Bürkle Liquid Cup Sampler, V4A stainless steel, 100 ml, 5357-0001
Anyone wishing to take a sample from a specific point in a tank, basin or open container without having to reach across the entire vessel or decant the contents needs a tool with sufficient reach and a clean collection cup. The Liquid CupSampler from Bürkle is a stainless steel V4A (1.4404) sample scoop designed precisely for this purpose. It collects liquids of varying viscosities, even if they contain particles, at a precisely specified depth.1,060-millimetre reach for targeted samplingThe CupSampler measures 1,060 millimetres in total and can be immersed to a depth of up to 950 millimetres; the handle alone is 1,000 millimetres long. At the lower end is a collection cup with a capacity of 100 millilitres and an external diameter of 55 millimetres, which collects the sample as soon as it reaches the target point. With this handle reach, the sample can be extracted without having to lean over the rim of a deep container or use a step stool, which helps maintain good posture, particularly when taking frequent samples from the same container.Also suitable for viscous and particulate mediaUnlike a simple ladle, Bürkle states that the CupSampler also collects liquids with higher viscosity and containing particles without the cup becoming clogged. This makes it suitable for applications in the chemical, food and cosmetics industries, where samples are rarely purely aqueous and the consistency can vary from batch to batch.Screw-on cup for switching between samplesThe collection cup can be unscrewed and thus thoroughly cleaned before the next sample is taken. When taking a series of samples from several batches or preparations, this prevents residues from the previous sample from contaminating the next one. The handle and cup are made entirely from V4A stainless steel, ensuring that even strong cleaning agents do not damage the surface.Batch sampling in goods-in inspectionIf several drums or tank wagons from a single delivery are sampled in succession to detect variations between batches, the CupSampler can be used directly one after the other for each sample. After each use, only the cup is unscrewed and cleaned; the rest of the tool remains in use as is. This is quicker than with samplers where the entire assembly must be dismantled between two samples.Other liquid samplers available on requestBürkle also supplies collectors for liquids with different opening designs, such as the liquid collector with a thumb-operated opening, which, like the CupSampler, is made from V4A stainless steel. The difference lies in how the sample enters the collection container: With the CupSampler, an open cup is immersed directly into the liquid; with a collector featuring an opening mechanism, the sample is only released at the target point via a flap or by pressing with the thumb. For applications where an opening is only required at the target point, it is worth considering this alternative before placing an order.Where the limitations lieThe CupSampler is a target-point sampling tool, not an all-layer sampler. Anyone requiring a representative sample from the entire depth of a tank or tank wagon is better served by the Bürkle immersion vessel, which operates with flow-optimised flow flaps. The CupSampler is not the right choice for petroleum products and other media in potentially explosive atmospheres, as it has no documented explosion protection. For such applications, the Ex immersion bottle and the Mini immersion bomb are available, which Bürkle specifies for use in explosion protection zone 0.Typical applicationsTargeted sampling from tanks, basins or open containers in the chemical industrySampling in food production, including viscous or particulate-laden mediaQuality control in cosmetics productionBatch sampling from multiple batches or lots; quick to clean thanks to the screw-off beakerTechnical detailsMaterialV4A stainless steel (1.4404)Overall length1,060 mmMax. immersion depth950 mmOuter diameter55 mmCapacity of collection cup100 mlCollector height60 mmHandle/stem length1,000 mmContentsLiquid Cup SamplerService and procurementIf, in addition to spot samples, you occasionally require all-layer or ex-samples, it is best to coordinate your order with LT Laborhandel straight away to include the appropriate immersion containers, rather than placing a second order later. A consolidated order can also be arranged for larger quantities required for multiple workstations.

Bürkle Glass Immersion Bottle for Liquid Sampling, brass and clear glass, 1,000 ml, 5365-4000
Anyone taking a sample from a clarification tank or a process pipe often wants to see straight away how cloudy or discoloured the liquid is, without having to decant it first. The Bürkle glass sampling bottle combines a brass sampling frame with a clear glass collection vessel; according to Bürkle, it is suitable for use in potentially explosive atmospheres in Ex protection zone 0, explosion groups IIA and IIB.Clear glass container with a capacity of 1,000 millilitresThe clear glass container holds 1,000 millilitres and makes the sample visible immediately as it is drawn, without the need for decanting. The outer diameter is 149 millimetres, the total height is 330 millimetres, of which 140 millimetres is accounted for by the collection vessel. Weighing 3.2 kilograms, the bottle sinks rapidly, much like the brass version, even though part of the assembly is made of glass.Visual inspection directly at the sampling pointAs the container is made of clear glass, the turbidity or discolouration of a sludge or water sample can be assessed right at the edge of the tank before the sample is sent to the laboratory. This helps with the monitoring of treatment stages, as it allows a quick on-site assessment of whether a sample is representative enough for further analysis, or whether a new sample needs to be taken.Easy-Click closure for quick bottle replacementThe cap features an Easy-Click mechanism made from electrically conductive polyamide. This allows the glass bottle to be quickly removed from the immersion rack and replaced with an empty one, ensuring minimal delay between two sampling operations.Brass, copper and conductive polyamide: only spark-free materialsThe immersion frame is made of nickel-plated brass, supplemented by copper and seals made of acrylonitrile-butadiene rubber and polyamide. None of the materials used in the construction are spark-prone, ensuring that the entire assembly remains suitable for use in hazardous areas, even though the collection vessel itself is made of glass.Maintenance between sampling sessionsAs the glass container is mounted separately from the brass frame, it can be removed for cleaning and rinsed independently of the metal parts. When taking serial samples from several clarifiers in succession, this reduces the time required for changeovers, as the frame and container can be cleaned in parallel rather than having to be processed one after the other. After use, the entire assembly can be left to dry before being lowered back into the basin or tank.Weight and handling compared to the brass versionAt 3.2 kilograms, the weight of the glass version is only slightly less than that of the all-brass bottle, which weighs 3.3 kilograms. This makes little difference to how quickly it sinks; both versions reach the bottom of a tank or basin rapidly. The difference is most noticeable at the edge of the basin: the glass version makes the sample taken immediately recognisable, whereas with the solid brass version, it is only after opening that it becomes clear what has actually been taken.For sewage treatment works as well as for mineral oil samplesBürkle specifies two areas of application for the glass immersion bottle: sludge and water samples in sewage treatment works, as well as crude oils, fuels, heating oils, petroleum and liquid lubricants. For groundwater samples taken from outside tanks, LT Laborhandel also stocks the AquaSampler. If, on the other hand, the higher explosion group IIC is required – for example, with certain fuels – the brass Ex sampling bottle is the more suitable choice, as, according to Bürkle, it is also suitable for IIC. The sampling vessel is available for full-depth samples with larger volumes.Typical areas of applicationSampling in sewage treatment works, sludge and water samplesVisual inspection of the sample directly at the sampling pointCrude oils and liquid petroleum productsFuels, special and test petrol, heating oils, kerosene, liquid lubricantsWork in areas for which Bürkle specifies Ex protection zone 0, explosion groups IIA and IIBTechnical detailsMaterialsImmersion frame: brass; container: clear glass; seal: electrically conductive polyamideDesignEasy-Click closure, non-sparking materialsCapacity1,000 mlOuter diameter149 mmTotal height330 mmHeight of collection container140 mmHeight with handle330 mmWeight3.2 kgExplosion protection according to BürkleSuitable for Zone 0, explosion groups IIA and IIBContentsLiquid sampler, immersion bottle, glassService and procurementIf sampling is carried out regularly at both sewage treatment works and oil tanks, it is worth checking with LT Laborhandel whether, in addition to the glass version, the brass variant with a higher explosion group is also included in the range.

Bürkle GeoSampler soil sampler, V2A stainless steel, 560 mm, 5350-5003
Anyone wishing to take a full-depth sample from a lawn or light soil needs a tool that can be driven into the ground and pulled out again by hand, without the need for a drill or heavy equipment. The GeoSampler, made from V2A stainless steel, is designed specifically for these light soils and is available in two lengths – 560 and 810 mm – each with a 300 mm chamber length for the actual sampling.Full-depth sample by handThe GeoSampler is pressed into the ground by hand, taking a continuous cross-sectional sample over the entire chamber length of 300 mm. This is suitable when you are interested not just in a single depth but in a profile across several soil layers, for example to see how soil type or moisture content changes from the surface down into deeper layers. A hand drill or a motorised drilling aid is not required for this type of sampling.Two lengths, with and without a foot restThe shorter version, with a total length of 560 mm, has a tube diameter of 11 mm and does not feature a foot rest. The longer version, at 810 mm, has a slightly larger tube diameter of 14 mm and a foot rest, which makes it easier to drive the tube into firmer soil.For light soils, grassland and lawnsBürkle describes the GeoSampler as a tool for light soils, grassland and lawns. For heavier, stony soils, where more force and a more robust design are required, the Pürckhauer – made from the same material class – is the more suitable choice.Cleaning between two sampling pointsThe GeoSampler’s V2A stainless steel can be quickly wiped down or rinsed between two sampling points to ensure that soil residues from one area do not contaminate the next sample. This is particularly important when, as part of a survey, several areas with different soil conditions are sampled in quick succession.Handling in the fieldThe GeoSampler is pressed directly into the ground by hand without the need for tools and is pulled out again after sampling. With the shorter version without a foot rest, body weight and arm strength are usually sufficient for this; with the longer version with a foot rest, you can apply additional pressure with your foot, which is particularly helpful on slightly firmer ground. Both versions are made from V2A stainless steel and are therefore designed for repeated outdoor use.Soil profile rather than a single depthUnlike a soil cylinder, which only samples a specific depth, the GeoSampler, with its 300 mm chamber length, provides a continuous sample across the top 30 centimetres of the soil. Anyone wishing to know whether soil type, moisture content or compaction vary within this zone can determine this directly from the soil column collected, without having to take several individual samples from different depths.Typical applicationsSoil sampling on grassland and lawnsLight, slightly compacted soilsFull-depth samples for agricultural or horticultural soil analysesTechnical detailsSampling methodFull-depth sample/cross-section sampleDrive typemanually operatedMaterialV2A stainless steel (1.4301)Chamber length300 mmVariants at a glanceItem numberTotal lengthPipe ØOuter diameterFootrest5350-5003560 mm11 mm17 mmwithout5350-5006810 mm14 mm20 mmwith footrestTube and outer diametersThe tube diameter is 11 millimetres for the shorter version and 14 millimetres for the longer version, whilst the outer diameter is 17 and 20 millimetres respectively. The smaller the diameter, the less force is required to push it into the soil; however, the amount of soil extracted per puncture is reduced. This is not a disadvantage for a quick survey sample across several areas; however, for a larger analytical sample from a single puncture, the larger diameter of the 810 mm version may be advantageous.Contents of the deliveryGeoSampler soil sampler in the selected lengthService and procurementThe GeoSampler is generally sufficient for light soils; for heavier or stony soils, switching to the Pürckhauer is recommended. Which of the two lengths is most suitable depends on how deep the soil profile of interest extends and how easily the soil can be worked on site. LT Laborhandel stocks both lengths of the GeoSampler individually and can also advise on the choice between the GeoSampler and the Pürckhauer if required. If you have any queries regarding the appropriate model, please contact LT Laborhandel for assistance.
Bürkle AquaSampler groundwater sampler, FEP/PTFE, 350 ml, 5308-0350
When sampling groundwater from a inspection chamber, the sampler must not get caught on the edge of the chamber or the inner wall whilst being lowered; otherwise, the sampling process will be delayed or the sample will be contaminated by contact with foreign material. The AquaSampler is designed for standard well shafts with an inspection opening of 2 inches or larger and can be inserted and withdrawn without jamming, even if the shaft is several metres deep.Ultra-pure material for sensitive analysisThe AquaSampler is made from ultra-pure FEP/PTFE with a non-stick surface. This reduces the risk of residues from a previous sample adhering to the inner wall and contaminating the next sample, which is particularly relevant in trace analysis, where even the smallest contaminants can distort the measurement result.Suitable for 2-inch shafts without jammingWith an external diameter of 45 millimetres, the AquaSampler fits through the inspection openings of standard well shafts from 2 inches upwards. Rounded edges and a threaded connection further facilitate cleaning between two sampling operations at different measurement points.Three sizes for different sampling requirementsThe AquaSampler is available in three volumes: 350, 700 and 1,050 millilitres. The small size is sufficient for individual parameters or rapid on-site tests, whilst the larger volumes are suitable for samples that are analysed for several parameters simultaneously in the laboratory or where part of the sample is retained as a reference sample. The larger the collection container, the less frequently it is necessary to take further samples from the same sampling point, which reduces the time required per sampling point in the case of deep or hard-to-reach shafts.Autoclavable for reuseAccording to the manufacturer’s specifications, the AquaSampler is autoclavable and can therefore be fully sanitised between sampling sessions at different measurement points. For practical use at the measurement point, a PTFE rope attachment sleeve is included, which allows the sampler to be secured to the shaft rope without any metal parts coming into contact with the sample.Why use a specialised sampler for wells and manholes?An open scoop or a submersible vessel for liquids from accessible containers is virtually impossible to handle in a narrow inspection shaft several metres deep. The AquaSampler is specifically designed for this situation: slim enough to fit through the manhole opening, fitted with a rope attachment for lowering and raising, and made from a material that leaves no residues on the sample when it comes into contact with the manhole wall.Groundwater monitoring across multiple sampling pointsWhen sampling is carried out at several wells or inspection shafts as part of a monitoring programme, ease of handling in hard-to-reach locations is just as important as sample purity. Rounded edges, a lightweight plastic body and ease of cleaning make the AquaSampler practical for recurring campaigns at varying sampling points.Sampling procedureThe AquaSampler is attached to the PTFE rope-fastening sleeve and lowered into the shaft until it reaches the desired depth in the water body. Once filled, it is hauled back up using the same rope, without hands or tools coming into contact with the sample. For the next sampling point, autoclave sterilisation is sufficient before the sampler is reused.Typical applicationsGroundwater monitoring at wells and inspection shaftsSampling of seepage water or process water in environmental analysisContaminated site investigation and soil protectionTrace analysis with high requirements for sample purityTechnical detailsMaterialFEP/PTFE, ultra-pure, non-stick surfaceOuter diameter45 mmSterilisableautoclavable (manufacturer’s specification)Overview of variantsItem numberCapacity mlTotal height mmHeight of collection container (mm)Net weight kg5308-03503504504100.465308-07007007907500.765308-10501,0501,2221,0811,039Contents of deliveryAquaSampler groundwater sampler in the selected size1x PTFE rope attachment sleeveService and procurementThe size suitable for each sampling point depends on the shaft diameter and the required sample volume.

Bürkle ViscoSampler sampler for viscous substances, PP, 60 cm immersion depth, 160 ml, 5331-1060
Anyone taking a sludge sample from a settling tank two metres deep won’t get very far with a simple beaker: the medium is too viscous to be collected cleanly, and contact with the previous sample will skew the result. The ViscoSampler PP extracts such samples from deep within using a suction piston, without the user having to reach into the medium themselves. The polypropylene range, with three lengths offering immersion depths from 60 to 200 cm, covers tanks and basins of varying depths.Suction piston instead of scoopingThe ViscoSampler works like a large pipette. The tube is inserted into the medium to the desired depth; the piston draws in the sample and holds it in the tube until it is expelled at the destination. Surfaces are manufactured to be non-porous and free of undercuts; a round thread replaces the usual tapered thread, thereby reducing the number of places where dirt can accumulate. The sampler can be completely dismantled for cleaning.Three lengths, three sample volumesThe shortest version, with a 60 cm immersion depth, holds 160 ml and is suitable for shallow containers or basins with an easily accessible surface. The medium length of 100 cm holds 300 ml, whilst the longest version, with a 200 cm immersion depth, holds 650 ml and can also reach the bottom of deeper tanks or settling tanks. Anyone who regularly takes samples from containers of varying depths can select the appropriate length for each task, rather than having to switch between a single version that is either too short or too unwieldy.Material and sealsThe tube and piston are made of polypropylene, whilst the seals are made of PTFE. A Declaration of Conformity for the PTFE seals is available in accordance with EU Regulation 1935/2004, EU Regulation 10/2011 and the GMP Regulation (EC) 2023/2006. It specifies concrete migration limit values for the PTFE components used, including for tetrafluoroethene and perfluoropropylperfluorovinyl ether, and thus confirms their suitability for contact with the tested media. Bürkle also provides a general material declaration for the plastic parts made of PP, PTFE and FEP across the entire ViscoSampler range.When the PP version is the right choiceFor most viscous media such as slurries, silt or oils, polypropylene is a suitable material. For more aggressive chemicals, the ViscoSampler version made from PTFE/FEP offers greater chemical resistance. For smaller sample volumes of up to 75 ml, the Mini ViscoSampler made from V4A stainless steel is the more compact alternative. If the samples are not slurries or liquids but solid soil samples, the GeoSampler or the Pürckhauer are more suitable.Cleaning between two sampling operationsAs the ViscoSampler can be completely dismantled, each individual part can be cleaned separately between sampling operations. This is important whenever samples are taken consecutively from different batches or containers: residues from the previous sample in the tube or on the piston would otherwise contaminate the next sample. The non-porous, undercut-free surface further facilitates this residue-free cleaning, as viscous material adheres less to smooth surfaces than to edges or crevices.Typical applicationsSludge and silt from clarifiers and settling tanksAqueous clay and soil samplesSediment from tanks and containersOils and emulsionsCreams and other paste-like productsTechnical detailsMaterial of tube and pistonPolypropylene (PP)Seal materialPTFEOpening diameter10 mmOuter diameter32 mmTube diameter25 mmDesignCan be dismantled for cleaningCompliance with standards for sealsEU 1935/2004, EU 10/2011, GMP (EC) 2023/2006Overview of variantsItem numberMax. immersion depthTotal sample volumeTotal length5331-106060 cm160 ml770 mm5331-1100100 cm300 ml1,170 mm5331-1200200 cm650 ml2,170 mmContentsViscoSampler PP, sample extractor for viscous substances, in the selected lengthService and procurementThe appropriate length and sample volume for a particular application depend on the depth of the container and the required sample quantity. For deep tanks or settling tanks, it is worth considering the 200 cm version, even though in everyday use only the upper layers are usually sampled, as this avoids the need for a second order later on for special cases. LT Laborhandel stocks each of the three ViscoSampler PP lengths individually and, if required, can also advise on the choice between the PP and PTFE/FEP versions. If you have any queries regarding the appropriate size or the combination of several samplers for different media, please contact LT Laborhandel for assistance.
Bürkle PharmaScoop pharmaceutical scoop, V4A stainless steel, 10 ml, 5324-0010
Sampling of powders and granules in pharmaceutical production requires clean transitions between batches. A quality assurance (QA) staff member taking an incoming goods sample from a drum must ensure that no residue from the previous sample is carried over into the new batch by the scoop. This is precisely why the PharmaScoop is manufactured to be completely free of edges, gaps and undercuts. With nine sizes ranging from 10 to 3,000 millilitres, the range covers almost any sample volume, from small retention samples in the laboratory to larger batches during incoming goods inspection.Edge-free design for high hygiene standardsEvery sharp edge, every gap and every undercut is a place where powder residues can accumulate and be transferred to the new sample the next time the scoop is used. The PharmaScoop completely avoids such areas and is, in addition, high-gloss polished inside and out in V4A stainless steel (1.4404, AISI 316L). The smooth surface can be cleaned without leaving any residue, as required when sampling powders and granulates in the pharmaceutical industry. The material is certified for food contact in accordance with EU Regulation 1935/2004; Bürkle provides a collective certificate covering several V4A items for this purpose.Nine sizes for every sample quantityThe smallest scoop holds 10 millilitres and is suitable for very small samples, for example when only a small amount of material is available for a retentive sample. The largest, with a capacity of 3,000 millilitres, can hold a significantly larger quantity of powder in one go, which is practical for checking entire containers. In between, there are seven further sizes at 50, 100, 500, 750, 1,000, 1,250 and 1,700 millilitres, each with its own internal diameter and overall length (see table below). Those who regularly test different batch sizes can thus select the appropriate scoop for each task, rather than switching between one that is too small and one that is too large when using a single size.Selection guide based on sample volumeFor small retention samples in the laboratory, such as during incoming goods inspections of individual raw material batches, sizes ranging from 10 to 100 millilitres are usually sufficient. The sizes in the medium range of 500 to 1,250 millilitres are those most frequently used when sampling larger containers or when checking mixed batches. The two largest sizes, 1,700 and 3,000 millilitres, are suitable when a representative quantity needs to be taken from a large container in a single go, such as from a big bag or a large drum.V4A material in practiceStainless steel 1.4404, also known as V4A or AISI 316L, is a material widely used in the pharmaceutical industry due to its high corrosion resistance. It can also withstand frequent cleaning with more aggressive agents without the surface or finish being affected, ensuring consistently smooth, residue-free surfaces throughout the scoop’s service life.Handle and HandlingThe handle is included in the overall length for all nine sizes and ranges from 53 to 124 millimetres, depending on the model. This is sufficient for most open containers and bags. If the short handle is not long enough for deeper containers such as drums or IBCs, the identically constructed PharmaScoop with a 600-millimetre-long handle and a scoop volume of 1,000 millilitres is available as a separate product.A suitable addition to the rangeFor very small sample quantities from 0.1 millilitres, the PharmaPicker is the more suitable choice; for cohesive, poorly flowing powders, the Scratcher powder sampler is recommended. If a closed system for zone sampling from drums is required instead of an open scoop, the Novartos Uno Pharma zone sampler is a better fit.Typical applicationsSampling of powders and granules in pharmaceutical productionRetention samples for quality assurance during goods receipt and releaseBatch control prior to further processing in mixers or filling linesSampling in cleanrooms where residue-free cleaning is mandatoryTechnical detailsMaterialV4A stainless steel (1.4404, AISI 316L)SurfaceHigh-gloss polished inside and outDesignedge-free, gap-free, undercut-freeColoursilverVolume range10 to 3,000 mlCompliance with standardsEU 1935/2004 (food contact, material tested)Overview of variantsItem numberCapacity mlInner diameter (mm)Length mmTotal length mmHandle/shank length mm5324-001010254499555324-0011503870121535324-001210050100175765324-0018500951402621205324-0013750952103301205324-00141,0001082353571245324-00151,2501261903101205324-00161,7001322353551205324-00173,000180215333120ContentsPharmaScoop pharmaceutical scoop in the selected sizeService and procurementThe appropriate size depends on the typical sample volume and the container opening at the workplace.

Bürkle Pigment Sampler, 25% groove opening, V4A stainless steel, 300 mm penetration depth, 5369-0300
Pigment powders and similar pastes tend to clump together inside a sampling lance and block the opening before a sample has even been taken. The pigment sampler with a 25 per cent slot opening is designed precisely for such agglomerating, slightly sticky bulk materials, featuring a narrower chamber opening that cleanly accommodates even low-flow materials.Narrow slot opening for sticky productsThe collection chamber opens across 25 per cent of the tube’s circumference, with a chamber width of 19 millimetres. This narrower opening is intended for pigments, pastes and other agglomerating or sticky bulk materials, which, with a wider opening, would easily get caught on the edge or block the chamber. The actual amount of material that enters the chamber depends not only on the width of the opening but also on the bulk material’s own tendency to stick together.Tapered piercing tipThe lance tapers to a point for insertion, enabling it to penetrate even firmer, clumped material. The tube and outer diameters are 30 millimetres, and it is made from V4A stainless steel (1.4404, AISI 316L). Once the lance has been inserted to the desired depth, it is rotated or moved slightly so that the collection chamber fills with the surrounding material before it is withdrawn again.Three lengths to suit container heightThe penetration depth ranges from 300 to 600 to 900 millimetres; the total length is accordingly 432, 732 or 1,032 millimetres. The sample volume increases with length from 145 through 312 to 480 millilitres; for quality assurance checks on incoming goods, the shortest version is usually sufficient, whilst the longer lance is required for inspections deep within a silo or container. As the chamber remains open throughout the entire penetration depth, a single length can be used to take a cross-section through several layers of the container, rather than merely sampling a single point.Markings and material certificationBürkle labels the product with the pictogram ‘Manufactured in accordance with DIN standard’, without specifying the exact standard number on the product page. For the stainless steel components used in this series, a material certificate from the manufacturer is also available, confirming the material specification 1.4404.Typical industriesThe pigment sampler is used wherever colour and pigment powders, printing ink pastes or similar sticky precursors are tested for batch conformity, for example in the paint and varnish industry or in the chemical production of pigment concentrates. An inspector who needs to approve a new batch of pigment on receipt of goods uses the lance to draw a sample from the centre of the sack or drum without having to open the container completely.Selection based on slot openingFor more adhesive or sticky products, which are less likely to enter the chamber with a 25 per cent slot opening, there is the identically constructed pigment sampler with a 50 per cent slot opening. The wider chamber accommodates a smaller sample volume per penetration depth, but this makes it easier to collect highly adhesive material. For cohesive powders without a pronounced tendency to stick, the Scratcher powder sampler is an alternative; for samples taken from silos from above, the SiloPicker is recommended.Typical applicationsSampling of pigments, colour pastes and similarly sticky bulk materialsIncoming goods inspection of agglomerating powders in chemical and pharmaceutical productionTesting of clumped or slightly caking materialsThixotropic and viscous liquidsTechnical detailsMaterialV4A stainless steel (1.4404, AISI 316L)Pipe diameter30 mmOuter diameter30 mmChamber width19 mmChamber opening25 per cent of the tube circumferenceNumber of collection openings1Overview of variantsItem numberInsertion depth mmTotal length mmSample volume ml5369-03003004321455369-06006007323125369-09009001,032480Scope of deliveryPigment sampler for agglomerating media, 25% slot opening, in the selected lengthService and procurementThe appropriate length depends on the insertion depth of the respective container; the sample volume increases automatically with the length. LT Laborhandel supplies the pigment sampler with a 25 per cent slot opening in all three lengths and, if required, can also coordinate its use with other samplers from the range – for example, where both sticky pigments and other bulk materials are tested in the same facility. If you have any queries regarding the choice between 25 per cent and 50 per cent slot width, or regarding other samplers for powders and pastes, please contact LT Laborhandel for further assistance.
Bürkle Multi-Collector Multi-stage Sampler, V4A stainless steel, 430 mm, 5316-3055
A sack in the goods-in area, a horizontal drum in production or a loose pile in the storage area: each of these situations requires a probe that can be inserted vertically from above or horizontally from the side and only releases its samples at the desired depth. The V4A Multi-Sampler is made entirely of 1.4404 stainless steel (V4A, AISI 316L) and is available in three sizes, with penetration depths ranging from 430 to 1,355 millimetres, featuring either three or five sampling chambers.Suitable for use in sacks, drums, silos and stockpilesThe lance can be inserted vertically into a silo or a big bag, or horizontally from the side into a sack or a horizontal drum. A twisting motion of the handle opens the collection chambers only at the point where the sample is to be taken, and closes them again as the lance is withdrawn. This allows zone profiles to be taken even where a container is not accessible from above, such as in the case of horizontally stored drums or piles of material on the ground.Solid stainless steel tube instead of a PTFE coreUnlike the V4A/PTFE multi-sampler, this version does not have a polytetrafluoroethylene core within the tube. The tube, made entirely of stainless steel, is more robust against intensive use and abrasive particles, though it is slightly heavier than the PTFE-core variant. The seals are made of acrylonitrile-butadiene rubber (NBR), whilst the mechanism also incorporates components made of polytetrafluoroethylene (PTFE). Anyone who uses the sampler several times a day and is sensitive to every gram of weight will find the lighter PTFE-core version to be the more suitable alternative.Removable tip for cleaningThe tip of the lance can be removed. This makes cleaning easier between two sampling operations on different materials, particularly when residues from the collection chambers or from the tip itself need to be completely removed before the next sample.Three sizes ranging from 430 to 1,355 millimetresThe shortest version (5316-3055) has a penetration depth of 430 millimetres and three chambers, each with a capacity of 14 millilitres, totalling 42 millilitres. This short size is only available in the version made entirely from stainless steel; it is not available in the V4A/PTFE variant. The medium size (5316-3085) measures 710 millimetres and has three chambers, each with a capacity of 17 millilitres, totalling 51 millilitres. The longest version (5316-3150) measures 1,355 millimetres and has five chambers, each with a capacity of 17 millilitres, totalling 85 millilitres.Chamber length and spacing increase with the sizeAs the size increases, not only does the number of chambers change, but so do their length and the distance between them. In the shortest version, the chambers are 80 millimetres long and 56 millimetres apart; in the two longer versions, the chamber length is 100 millimetres and the distance between them is 168 and 195 millimetres respectively. If you wish to test zones as evenly as possible across the entire penetration depth, you will find the exact values for each size in the table below.Applications by sectorIn the food industry, the Multi-Collector tests the homogeneity of cereals, maize, nuts, powders and granulates. In the pharmaceutical industry, it is used for quality control of raw materials as well as intermediate and end products; in the chemical industry, it is used to analyse chemicals and powders for homogeneity and compliance with specifications. In the construction sector, materials science and research and development, it is used for sampling bulk materials such as sand and gravel.Material tested in accordance with EU Regulation 1935/2004A Bürkle collective certificate in accordance with EU Regulation 1935/2004 is available for the parts in contact with the medium, which are made of stainless steel, aluminium and PTFE; this confirms their suitability for food contact. The certificate covers several Bürkle products and does not constitute a product-specific individual test.Choice within the Multi-Collector rangeWithin the Multi-Collector family, this version differs from the Multi-Collector V4A/PTFE in that it features a continuous stainless steel tube and an additional short version with a penetration depth of 430 millimetres. If, instead of a zone profile, only a targeted sample from a single depth is required, the Uno sampler – a targeted sampler from the same material family – is sufficient. If the sample is intended to represent the entire layer height rather than individual zones, the V4A all-layer sampler is more suitable.Typical applicationsZone profiles of bulk materials in sacks, drums, silos, big bags and stockpilesHomogeneity testing of cereals, maize, nuts, powders and granulates in the food industryQuality control of raw materials, as well as intermediate and end products, in the pharmaceutical industryAnalysis of chemicals and powders in the chemical industrySampling of sand, gravel and other bulk materials in the construction industry and materials scienceTechnical detailsMaterialV4A stainless steel (1.4404, AISI 316L)SealAcrylonitrile-butadiene rubber (NBR)Other componentsPolytetrafluoroethylene (PTFE)Pipe diameter25 mmChamber width12 mmCompliance with standardsEU 1935/2004 (food contact, collective certificate)Overview of variantsItem numberInsertion depth (mm)ChambersSample volume per chamber mlTotal sample volume mlTotal length mmChamber length mmDistance between chambers (mm)5316-30554303144258080565316-3085710317518831001685316-31501,355517851,540100195Scope of supplyMulti-stage sampler Multi-Collector V4A in the selected sizeService and procurementWhether the version made entirely of stainless steel or the lighter V4A/PTFE version is more suitable depends on the frequency of use and the requirements regarding weight and robustness.

Bürkle PowderProof vertical sampling lance, V4A/V2A stainless steel, granules, 600 mm, 5302-0601
A drum, a barrel or a big bag can be opened from the top, but it is virtually impossible to obtain a representative sample from the centre or the bottom of the container using a hand shovel. The PowderProof vertical lance is inserted from the top and extracts the sample material using a motorised spiral conveyor from the set depth – either 600, 900 or 1,200 millimetres.Insertion from the top into large containersUnlike the horizontal lance, which is inserted from the side, this version is inserted vertically from above into open containers. This is suitable for drums, barrels and big bags with unobstructed access from above, when a sample needs to be taken from a specific depth rather than just from the surface.Three insertion depths for containers of different sizesThe 600-millimetre version is suitable for small to medium-sized drums, the 900-millimetre version for larger barrels, and the 1,200-millimetre version for tall big bags or stacked containers. As the insertion depth increases, so does the total length of the lance from 907 to 1,207 to 1,507 millimetres (see table below), whilst the weight rises accordingly from around 6.2 to up to 7.1 kilograms.Motorised feeding instead of a hand shovelA Bosch battery-powered drive unit drives the feed screw inside the lance, ensuring that the sample material is fed evenly from the set depth into the sample bag provided. For repeated sampling from the same type of container, this ensures a more consistent extraction than a manual tool, regardless of the operator’s manual strength.Powders and granules for each penetration depthFor each of the three lengths, there is a version for powders with a particle size of up to 2 millimetres and one for granules with a particle size of 2 to 4 millimetres, making a total of six variants. The housing, drive unit and accessories are identical across all six; the differences lie in the feed screw, overall length and weight.Cleaning after samplingAfter use, the lance can be cleaned of any residual material using the cleaning brush supplied before it is used for the next sample. When changing materials, thorough cleaning between samples prevents residues from the previous sample from contaminating the next batch.Typical applicationsSampling of free-flowing powders and granules from open containers such as drums, barrels or big bagsZone sampling from a defined depth rather than just from the surface of the containerIncoming goods inspection of large containers in chemical and food processing plantsRecurring sampling with a consistent flow rate thanks to a motorised driveTechnical detailsMaterialStainless steel V4A (1.4404) / V2A (1.4301)Outer diameter25 mmDriveBosch cordless drive unitSterilisableAutoclavable (manufacturer’s specification)Overview of variantsItem numberType of bulk materialInsertion depth mmTotal length mmParticle sizeNet weight kg5302-0601Granules6009072 to 4 mm6.2145302-0602Powder600907up to 2 mm6.35302-0901Granules9001,2072 to 4 mm6.55302-0902Powder9001,207up to 2 mm6.75302-1201Granules1,2001,5072 to 4 mm6.895302-1202Powder1,2001,507up to 2 mm7.1455Select the depth to suit the containerA 200-litre drum can usually be fully sampled using the 600-millimetre version. For taller drums or big bags with a higher fill level, the 900- or 1,200-millimetre version is the safer choice, ensuring that the sample comes from the actual centre of the container rather than just the top layer.Scope of supplySampling lance with feed spiralBosch drive unit2 x rechargeable batteryBattery quick chargerAdapter for sampling lance100 x sample bags, 400 mlBag holder clipPliers for retaining ringCleaning brushRegulatory informationThe PowderProof vertical lance is classified as an electrical appliance under the German Electrical and Electronic Equipment Act (ElektroG) due to its battery-powered drive unit. Information on return at the end of its service life can be found under ‘Environment and Disposal’. The batteries supplied must not be disposed of with general household waste, but must be returned via standard household battery and rechargeable battery collection schemes.Service and procurementIf the container is only accessible from the side – such as a horizontal sack – the PowderProof horizontal lance is a better fit. The PowderProof feed spiral is available separately as a spare part, serving as a wear part for both lance orientations. For cohesive, non-free-flowing substances where the feed spiral reaches its limits, the Scratcher powder sampler is more suitable; for smaller manual samples without a motor, the PharmaScoop pharmaceutical scoop is recommended. LT Laborhandel stocks each of the six variants individually and, where required, coordinates their use with the horizontal lance for mixed sampling tasks.
Bürkle ‘Mole’ Drill Head ‘Riverside’, interchangeable head for soil samplers, iron/steel, 5350-1035
Hard, encrusted soils and gravelly sites slow down a soil sampler more than any other soil type in the Maulwurf range. A drill head that encounters resistance across its full width whilst drilling makes hardly any progress here. The ‘Maulwurf’ Riverside drill head therefore utilises drill blades that extend beyond the core drill, reducing friction in the soil rather than forcing its way through hard ground with its entire surface area. Without this design, the only option in such locations would often be the laborious task of repeatedly repositioning the same head until a sample can finally be obtained.Drilling blades instead of a full faceUnlike the closed flanks of sand and combination heads, the Riverside head features drilling blades that extend beyond the actual core drill. This design reduces friction during penetration because the entire head surface is not working against the hard ground at once; instead, the blades loosen the material step by step. For hard, encrusted and gravel-intermixed soils, this is the crucial difference compared to heads with continuous flanks.Identifying encrusted soilsA hard crust often forms at sites that periodically dry out and then become re-wetted, such as along riverbanks, in former floodplains or on heavily compacted paths and open spaces. A standard auger head often hits the surface at such locations before it even penetrates deeper, softer soil layers. The Riverside head is designed precisely for this transition from a hard crust to the underlying, more gravelly material.Use with the Mole handleThe Riverside drill head also works exclusively in conjunction with the ‘Mole’ handle and shaft, which is 750 millimetres long. For deeper drilling in hard ground, the handle can be extended with a 100-centimetre extension (5350-1010) to provide greater force and reach during operation.Typical applicationsThe Riverside head is designed for hard, resistant soils, such as those found here:Sampling in hard, encrusted soilSampling of gravel-intermixed bank areas and former floodplainsSoil investigation on heavily compacted paths and squaresContaminated site investigation at locations with a hard surface layerRiverside or another bit?If the soil is gravelly but not hard and encrusted, the gravel drill head with its curved blades works more precisely because it clamps individual stones between its flanks. If individual large stones are blocking the borehole, rather than the entire soil being hard, the stone-catcher drill head removes these first. If the ground is merely coarse-grained and dry, but not encrusted, the coarse sand drill head is usually sufficient.Robust, maintenance-free constructionLike the other mole drill heads, the Riverside head is made of iron/steel and has a purely mechanical design, with no electronics that could be damaged by frequent contact with hard, stony ground. No calibration is required, nor does it have a charge level. To store it between uses, a dry place at room temperature is sufficient; any clinging soil residue should be removed before stowing.Technical detailsProduct typeReplacement drill head for the ‘Mole’ soil samplerDesignDrill blades protrude beyond the core drill, low frictionMaterialIron/steel (Bürkle material code FE)Country of originNetherlandsStorage conditionsRoom temperatureCompatible withMole handle with rod, 750 mm, 5350-1005ContentsMole drill head, RiversideThe Mole handle with rod is not included in the scope of delivery and must be provided separately or ordered at the same time.Service and procurementFor sites with a hard surface layer over softer, gravelly subsoil, LT Laborhandel can, on request, supply the Riverside head together with the gravel drill bit or the stone trap, ensuring that the correct head is to hand for every drilling depth, without the need to halt an exploration due to using the wrong head.

Bürkle liquid collector with thumb opening, V4A stainless steel, 380 mm, 5326-0001
Taking a liquid sample from a tank or container is not always easy with just one hand, particularly when you also have to hold a lid or railing. The liquid sampler with thumb-operated opening can be operated with one hand whilst being immersed and filled; the thumb opens and closes the sampling opening directly on the handle. Two sizes, with collection volumes of 50 and 100 millilitres and immersion depths of 380 and 450 millimetres respectively, cover shallow to medium-sized containers, ranging from smaller canisters to medium-height drums.One-handed operation via the thumb-operated openingThe opening on the collection container is controlled by a thumb button at the end of the handle. This allows the sampler to be immersed, opened at the desired depth, filled and resealed without needing the other hand for a separate mechanism. This is useful when, for example, a valve needs to be operated or a ladder held onto at the same time whilst working on a piece of plant. If, instead, the opening is triggered by placing the sampler on the base of the container, the identically constructed liquid collector with a push-to-open mechanism is a better fit.Two sizes for different containersThe smaller version holds 50 millilitres at a submersion depth of 380 millimetres and is suitable for shallower containers or smaller sample volumes, such as when taking frequent spot samples from smaller canisters. The larger version holds 100 millilitres and has an immersion depth of 450 millimetres, making it suitable for deeper containers or when a larger sample volume is required. A spout on the collection container facilitates the subsequent transfer into sample bottles for both sizes, without spilling liquid or soiling labels on the workbench.Material suitable for low-viscosity to viscous mediaThe sampler is manufactured entirely from V4A stainless steel (1.4404, AISI 316L) and is designed for low-viscosity to viscous media. The material can also withstand frequent cleaning between different samples without the surface or function of the opening being compromised. For thicker, paste-like substances where an open collection port is insufficient, standalone products such as the ViscoSampler are the more suitable choice.Use on tanks and open vesselsWhen taking a sample from a tank through a narrow access hatch or from a platform, every free hand often counts. The thumb-operated opening mechanism allows the sampler to be guided with the same hand used for immersion, whilst the other hand remains on the handrail or the container hatch. Particularly at elevated work stations with fall protection, this one-handed operation offers a practical advantage over samplers that require two hands to open and close.Addition to the sampler rangeLT Laborhandel offers further models for liquids that are too viscous for the liquid collector, or for sampling directly from the bottom of the container without using the thumb mechanism. This allows the appropriate sampler to be selected for different media and workflows within the same organisation, without having to introduce a completely new system for every new application. This also reduces the training required, as the basic principle of sampling remains consistent across all models.Typical applicationsSampling of low-viscosity to viscous liquids from tanks, drums and open containersQuality control during goods receipt and release of liquid raw materialsSampling in hard-to-reach places where only one hand is freeProcess control in chemical and pharmaceutical productionRecurring sampling on equipment where space is limited for both handsTechnical detailsMaterialV4A stainless steel (1.4404, AISI 316L)OperationThumb opening on the handle, one-handed operationOuter diameter32 mmSpoutSpout funnel on the collection containerCompliance with standardsEU 1935/2004 (food contact, parts in contact with the medium tested)Overview of variantsItem numberMax. immersion depth mmCapacity mlTotal length mmHandle/shaft length mm5326-0001380504602445326-0002450100540195ContentsFluid collector with thumb opening in the selected sizeService and procurementWhether the thumb opening or the top opening is more practical to use depends on the workflow involving the container.

Bürkle Spiralus Zone Collector, aluminium/PA, 1,320 mm, 5318-0145
Grain and pellets are coarse-grained and often settle in layers within a silo or railway wagon, depending on the conveying technology and the length of time they have been stored. The Spiralus zone sampler draws a sample through a spiral arrangement of slotted openings, which represents the individual depth zones of the lance, rather than mixing them as an open tube would. Two lengths, with penetration depths of 1,320 and 1,736 millimetres, cater for silos, lorry bodies and railway wagons of varying heights. This makes it possible to determine upon delivery whether a load is uniformly composed throughout its entire height or whether grain fractions have segregated.Eight sampling openings in a spiral arrangementEight sampling openings are arranged in a spiral pattern along the length of the lance. This arrangement ensures that the sample taken from each opening actually captures the material at that specific depth, rather than passing through adjacent slots. By rotating the lance, each chamber can be selectively opened and closed again, allowing the eight sub-samples to be taken separately. For a homogeneous composite sample without zone separation, the Aluminium All-Layer Sampler is the simpler choice.Designed for coarse-grained bulk materialsThe tube and external parts are made of aluminium, whilst the internal parts are made of polyamide. This combination is designed for coarse-grained materials such as grain, pellets or similar bulk materials, where fine particles or highly adhesive substances are not a factor. Polyamide is lighter than metal parts and further reduces the weight of the long lance. For finer or sticky powders, a stainless steel sampler with tighter tolerances is more suitable, such as those offered by Bürkle in its other product ranges.Two lengths for silos, lorries and rail wagonsThe 145-centimetre-long version achieves a penetration depth of 1,320 millimetres and has a sample volume of up to 770 millilitres. The 200-centimetre-long version achieves a penetration depth of 1,736 millimetres and a volume of 1,100 millilitres, making it suitable for deeper silos or heavily loaded railway wagons. Both lengths utilise the same chamber geometry with a chamber length of 92 millimetres and a chamber spacing of 125 millimetres, which means that samples taken with the two sizes can be directly compared and the same analysis method works for both sizes.Use during delivery and stock controlWhen grain or pellets are delivered by lorry or rail wagon, a sample taken from several depths shows whether the batch is uniformly composed throughout the entire load. In the warehouse itself, the same lance can be used to check regularly whether the material has segregated during its time in the silo or has absorbed moisture from below.For larger quantities: the Jumbo samplerIf a sample volume of 770 or 1,100 millilitres is insufficient – for example, because a larger reference quantity is required from a particularly large silo or bunker – Bürkle offers two models with a significantly larger tube diameter specifically for this purpose: the Jumbo Sampler Allschicht and the Jumbo Sampler Multi. The Spiralus lance, on the other hand, remains the slimmer and lighter solution for daily routine checks.Typical applicationsSampling of grain and pellets from silos, storage facilities, lorries and railway wagonsQuality and homogeneity testing of coarse-grained agricultural productsIncoming goods inspection upon delivery of large quantities of bulk materialsChecking whether material has segregated by grain size during transportRegular stock checks during prolonged periods of storage in silosTechnical detailsPipe materialAluminiumMaterial of internal componentsPolyamideCollection openings8 in total, arranged in a spiral patternChamber length92 mmChamber width22 mmChamber spacing125 mmPipe diameter / outer diameter38 mm / 50 mmCompliance with standardsEU 1935/2004 (food contact, parts in contact with the medium tested)Overview of variantsItem numberInsertion depth mmSample volume mlOverall length (mm)5318-01451,3207701,4605318-02001,7361,1002,000ContentsSpiralus zone manifold in the selected lengthService and procurementThe appropriate length depends on the height of the silo, lorry body or railway wagon from which the sample is taken.

Bürkle Allschicht collector, V4A stainless steel, 710 mm, 5316-2085
If a sample is intended to represent the entire layer height of a bulk material rather than individual zones, a zone profile comprising separate chambers is not the right tool. The full-layer sampler is manufactured entirely from V4A (1.4404) stainless steel and is designed for sampling over the full insertion depth, from the food and pharmaceutical industries through to the chemical industry.Made entirely of stainless steel rather than with a PTFE coreUnlike the V4A/PTFE Multi-Collector, the All-Layer Collector does not have a PTFE core, but is made entirely of V4A (1.4404) stainless steel. This makes it more robust against intensive use and abrasive particles, and corrosion-resistant even in damp or aggressive environments.Hygienic surface for sensitive sectorsThe smooth surface facilitates cleaning and disinfection. According to the manufacturer, the All-Layer Collector is autoclavable up to a maximum of 121 degrees Celsius for 20 minutes and can also be flame-sterilised, which reduces the risk of contamination between two sampling operations.ISTA-compliant seed samplingFor seed sampling, the Allschicht collector complies, according to the manufacturer’s specifications, with the ISTA standard for a seed length of 10 millimetres – such as for wheat and oats – and 5 millimetres – such as for flax and vetch. This makes it suitable not only for use in the food, pharmaceutical and chemical industries but also for seed inspection, where sampling requirements are strictly regulated.Two sizes with three or five openingsThe shorter version, with a penetration depth of 710 millimetres, has three collection openings and yields a sample volume of 130 millilitres; the longer version, with a penetration depth of 1,355 millimetres, has five openings and yields 260 millilitres. Both sizes correspond in penetration depth to the two versions of the Multi-Collector, and thus cover the same container heights.When a continuous sample is the better choiceIn the case of bulk materials that have become heavily segregated, a zone profile taken from individual chambers can indicate at which point in the container the quality deviates. If, on the other hand, the question is whether a batch as a whole meets the specifications, a continuous sample taken across the entire layer height is often more informative and quicker to analyse than several individual samples. For seed testing in accordance with ISTA guidelines, this design is mandatory in any case, as a representative sample covering the entire quantity is required here, rather than a spot zone sample.Suitable for flame sterilisation to meet particularly high hygiene requirementsIn addition to autoclaving, Bürkle explicitly mentions the option of flame-sterilising the all-layer sampler. This is an additional option if there is no time for a full autoclave cycle between two sampling operations, or if the sampler needs to be cleaned directly on the production line between two batches.Typical areas of applicationSamples taken across the entire layer height in the food, pharmaceutical and chemical industriesSeed sampling in accordance with ISTA specifications, for example for wheat, oats, flax or vetchApplications with high standards of hygiene and cleaningEnvironments containing abrasive particles or aggressive cleaning agentsTechnical detailsMaterialV4A stainless steel (1.4404)SealAcrylonitrile-butadiene rubber (NBR)Pipe diameter25 mmSterilisableAutoclavable up to a maximum of 121 °C for 20 minutes (manufacturer’s specification)Standard specificationISTA standard for seed lengths of 10 mm (e.g. wheat, oats) and 5 mm (e.g. flax, vetch), according to the manufacturer’s specifications.

Anyone who uses the all-layer sampler several times a day, for example when taking regular incoming goods samples, will notice this difference over the course of the working day. For occasional, less frequent sampling from tall containers, the greater weight of the long version is usually not a problem. Where there are frequent changes between several samples in a day, the shorter version may be the more practical choice, provided the insertion depth is sufficient for the container in question.Scope of deliveryV4A All-layer sampler in the selected sizeService and procurementIf a profile comprising individual zones is required instead of a continuous sample across the full layer height, the Multi-Sampler is more suitable. For a lighter aluminium version, the All-Layer Aluminium Sampler is recommended; for larger containers, the Jumbo All-Layer Zone Sampler is suitable. LT Laborhandel provides advice on selection and orders each size individually.
Bürkle Pürckhauer soil sampler, V2A stainless steel, 810 mm, 5350-5012
Stony or compacted soils quickly present a challenge to a simple soil sampler; a tool that is too flimsily constructed will bend or be almost impossible to pull out again. The Pürckhauer is designed precisely for this purpose: it is robust and features an embossed depth scale, and is available in two lengths: 810 and 1,175 mm.Robust construction for heavy soilsThe Pürckhauer features a detachable handle with non-slip rubber grips and a reinforced striking head, which makes it easier to drive into compacted or stony soils. From 60 cm onwards, the tip of the longer version (5350-5018) tapers, making it easier to withdraw from the soil.Depth scale and Nmin samplingAn embossed depth scale with 10-cm markings shows directly the depth from which the sample was taken, without the need to carry a separate tape measure. This makes the Pürckhauer suitable for Nmin sampling between 0 and 90 cm, as is standard practice in agricultural fertiliser planning to determine the available nitrogen in the soil. The embossed, rather than printed, scale remains legible even with frequent use and contact with soil.Two lengths for different profile depthsThe shorter version has a total length of 810 mm and a chamber length of 600 mm; the longer version has a total length of 1,175 mm with a chamber length of 1,000 mm. Both feature a depth scale with 10-cm graduations.Differences from the GeoSamplerFor light soils, grassland and lawns, the GeoSampler made from V2A stainless steel is sufficient and can be manoeuvred with less effort. As soon as the soil becomes stony or heavily compacted, the Pürckhauer, with its reinforced impact head, is the more robust choice.Tapered tip of the long versionIn the longer version (5350-5018), the tip tapers from 60 cm onwards. This reduces friction between the ground and the tube over the final few centimetres, thereby making it easier to withdraw the tool from deeper, often more heavily compacted soil layers. With the shorter version (5350-5012), which has a total length of 810 mm, this effect is less significant, as the penetration depth remains shallower.Why Nmin sampling requires a long chamberThe Nmin method assesses the available nitrogen across an entire soil profile, typically to a depth of 90 cm, often broken down by layer. The chamber length of 600 mm for the shorter version and 1,000 mm for the longer Pürckhauer version covers these depths in a single pass, rather than having to take several short individual samples one on top of the other and combine them.Handle and striking head in detailThe detachable handle with non-slip rubber grips can be removed for transport and reattached on site. The reinforced striking head absorbs the pressure or light impacts when driving the tube into firmer soil, without placing any strain on the tube itself.Typical applicationsSoil sampling in heavy and stony soilsNmin sampling from 0 to 90 cmProfile investigations across multiple soil layersTechnical detailsSampling methodFull-depth sample/cross-section sampleDrive typemanually operatedMaterialV2A stainless steel (1.4301)Scaleembossed, 10 cm graduationsOverview of variantsItem numberTotal lengthChamber lengthPipe diameterOuter diameter5350-5012810 mm600 mm13 mm20 mm5350-50181,175 mm1,000 mm18 mm25 mmTube and outer diametersThe tube diameter is 13 millimetres for the shorter version and 18 millimetres for the longer version, whilst the external diameter is 20 and 25 millimetres respectively. The larger diameter of the 1,175 mm version is suited to the greater chamber length of 1,000 millimetres and consequently provides more sample material per penetration; however, it also requires more force when driving into compacted soil than the shorter version with a chamber length of 600 millimetres. Those who regularly alternate between lighter and heavier soils will need to weigh up the greater sample yield of the long version against the greater force required to drive it into the ground.Scope of deliveryPürckhauer soil sampler in the selected lengthService and procurementFor heavy and stony soils, the Pürckhauer is the more robust choice compared to the GeoSampler, particularly when Nmin samples are regularly taken to a depth of 90 cm.

If you have any queries regarding the appropriate length or combining the Pürckhauer with the GeoSampler for different soil types, please contact LT Laborhandel for further assistance.
Bürkle liquid collector with top opening, V4A stainless steel, 425 mm, 5326-0003
Not every hand has room for a thumb button when inserting a sampler – for example, when holding a heavy container lid at the same time. The liquid collector with a contact-activated opening triggers the release as soon as the sampler touches the bottom of the container, without the need for any separate operation on the handle. Two sizes are available, with collection volumes of 50 and 100 millilitres and immersion depths of 425 and 500 millimetres respectively, suitable for both shallower and deeper containers.Opening by contact rather than thumb pressureAs soon as the tip of the sampler touches the bottom of the container, the collection opening opens automatically and fills with the liquid at that point. This makes handling straightforward when the bottom is easily accessible and no additional operation of the handle is required, for example when taking several samples in quick succession from similar containers. If, on the other hand, the opening is to be triggered at a specific depth rather than only when it reaches the bottom, the liquid collector with thumb-operated opening is the more practical choice.Two sizes with different immersion depthsThe smaller version holds 50 millilitres with an immersion depth of 425 millimetres and is suitable for shallower drums and canisters. The larger version holds 100 millilitres and has an immersion depth of 500 millimetres, for deeper containers or larger sample volumes. On both sizes, a spout on the collection container facilitates decanting into sample bottles; the handle is 349 millimetres long on both sizes, allowing for a consistent grip regardless of the size chosen and making it possible to switch between the two sizes during operation without needing to adjust.Material suitable for low-viscosity to viscous mediaThe sampler is manufactured entirely from V4A stainless steel (1.4404, AISI 316L) and is designed for low-viscosity to viscous media. The material is sufficiently corrosion-resistant for frequent contact with various liquids and can be thoroughly cleaned between samples without damaging the surface or the mechanics of the opening. For thicker, sticky liquids where an automatic bottom-contact mechanism does not trigger reliably, a sampler such as the ViscoSampler PTFE/FEP is more suitable.Use with recurring samplesWhere the same type of container is sampled regularly – for example, in a filling plant with similar drums – the automatic release mechanism saves one step per sample compared with manual operation. Over many repetitions throughout the day, this adds up to a significant time saving, particularly when several batches need to be released one after the other during ongoing operations.Addition to the sampler rangeFor liquids that are too viscous for the liquid sampler, or for applications where precise triggering at a specific depth is more important than automatic bottom contact, LT Laborhandel offers further models. This allows the appropriate sampler to be selected depending on the medium and the operational workflow, rather than having to use a single type for all applications. By ordering from LT Laborhandel, multiple models can be procured together and coordinated.Typical areas of applicationSampling of low-viscosity to viscous liquids from the bottom of tanks and containersQuality control during goods receipt and release of liquid raw materialsSampling where both hands are needed on the container itselfProcess control in chemical and pharmaceutical productionRepeated sampling from similar containers in quick successionTechnical detailsMaterialV4A stainless steel (1.4404, AISI 316L)OperationOpen by placing on the base of the containerOuter diameter32 mmHandle/shank length349 mmSpoutSpout on the collection containerCompliance with standardsEU 1935/2004 (food contact, parts in contact with the medium tested)Overview of variantsItem numberMax. immersion depth mmCapacity mlTotal length mmCollector height mm5326-0003425504551065326-0004500100531182ContentsFluid collector with top-loading opening in the selected sizeService and procurementWhether a top-opening or thumb-opening design is better suited to your workflow depends on whether you need to trigger the discharge at the base of the container or at a specific depth.

Bürkle Uno Collector Target-Point Sampler, V4A stainless steel/PTFE, 430 mm, 5316-1055
Not every sampling operation requires a depth profile across multiple levels. If only a single, targeted sample is required from a specific zone of a bag, drum, silo or stockpile, a sampling chamber is sufficient. The Uno sampler opens exactly one chamber at the desired depth and provides a spot sample, which can be analysed individually or combined with other spot samples to form a composite sample, depending on the requirements of the test specification.One chamber instead of multiple zonesUnlike the Multi-Sampler, which has three or five collection chambers, the Uno Sampler has just a single chamber. This makes it the simpler and more cost-effective choice when a complete zone profile is not required, but rather a targeted sample from a specific depth or zone. For businesses that predominantly take individual samples, the simpler design is also less prone to operator error than a device with multiple chambers.Combining several Uno samplers to create your own profileColoured caps distinguish between multiple Uno samplers when several samplers are deployed simultaneously from different depths within the same container. This allows a customised depth profile to be created without being restricted by the fixed chamber layout of a multi-collector, and individual target-point samples can be analysed separately if required, rather than being automatically mixed. This is useful when the depth intervals need to vary on a case-by-case basis, rather than being fixed within a single device.Material and sealAs with the multi-collector, the tube is made of V4A (1.4404) stainless steel with a PTFE core, whilst the seal is made of acrylonitrile-butadiene rubber (NBR). This combination ensures the sampler is easy to handle whilst also being chemically resistant to most bulk materials and cleaning agents, which is particularly beneficial when the chamber is frequently screwed on and off.Two sizes with different insertion depthsTwo insertion depths are available: 430 millimetres with a sample volume of 14 millilitres and 710 millimetres with a sample volume of 17 millilitres. The shorter version is suitable for shallower containers such as sacks, whilst the longer version is designed for deeper drums or silos where the target position is further down. The correct length is determined solely by the depth of the target position within the respective container, not by the volume of sample material required.Use in food and pharmaceutical facilitiesBürkle specifies that the material of the Uno sampler is suitable for foodstuffs, without reference to a specific standard such as EU 10/2011. According to the manufacturer’s specifications, the sampler is also manufactured in accordance with a DIN standard; however, Bürkle does not specify a particular standard number for this model. For applications with higher hygiene requirements, it is autoclavable according to the manufacturer’s specifications, meaning it can be fully decontaminated between use with different materials.Practical example: raw material inspectionIf, upon delivery, the aim is simply to check whether the material at a critical point in the drum – for example, near the bottom – meets the specifications, a single spot sample is sufficient and can be taken more quickly than a complete zone profile involving several chambers. The UNO sampler provides precisely this single sample without the need to sample and analyse the remaining zones, thereby reducing the testing effort per batch.Typical applicationsTargeted single sample from a specific depth or zone of a bulk materialCombination of several UNO samplers to create a customised depth profileQuality control of raw materials in sacks, drums, silos and big bagsSituations where a complete zone profile is not requiredTechnical detailsMaterialV4A stainless steel (1.4404) with PTFE coreSealAcrylonitrile-butadiene rubber (NBR)Pipe diameter25 mmSterilisableAutoclavable (manufacturer’s specification)Standard specificationAccording to the manufacturer, the product is also manufactured in accordance with a DIN standard; however, Bürkle does not specify a specific standard number on the product page.

Bürkle Novartos Multi Pharma 3-way zone collector, V4A stainless steel, 600 mm insertion depth, 5358-0603
Some validation guidelines require three samples per zone tested for homogeneity testing, rather than two. The Novartos Multi, with its 3-way sample extractor, draws three sub-samples from four to nine zones along the penetration depth in a single puncture, for tests where two duplicates are insufficient and a third sample is required as a reserve or for a second method.Three samples per zone, one punctureEach collection chamber accommodates three sample inserts (sold separately), which fill simultaneously at the same point when the lance is inserted. Distributed across the entire penetration depth, it delivers between 12 and 27 individual samples from a single penetration, depending on the length, without the need to penetrate each zone separately.Use in validation and releaseThree samples per zone provide more robust results than two, for example when a mixing batch is released for the first time or a mixing process is being validated. One of the three sub-samples can serve as a retained sample, whilst the other two can be used for the ongoing and a repeat test, without the need for a new puncture in the same zone for the repeat test. For a quality assurance team qualifying a new mixing plant for the first time, this provides a triple data set for each zone straight away, rather than having to carry out several sampling punctures at different times.Three lengths, increasing number of zonesAt a penetration depth of 600 millimetres, the lance has four zones with twelve chambers, with a total length of 800 millimetres. At 1,000 millimetres, there are seven zones with 21 chambers, with a total length of 1,200 millimetres. At 1,400 millimetres, there are nine zones with 27 chambers, giving a total length of 1,600 millimetres. The chamber spacing is 125 millimetres in the shortest and middle versions, and 135 millimetres in the longest.Material for the pharmaceutical sectorManufactured from V4A stainless steel (1.4404) with components made from 1.4571, tube diameter 25 millimetres, chamber length 30 millimetres, with the first collection chamber starting 55 millimetres from the tip of the lance.Why the chamber position mattersBecause the first collection chamber begins only 55 millimetres behind the lance tip, the top 55 millimetres of the container are left without a sample of their own. The chamber spacing of 125 or 135 millimetres determines how closely or widely the zones are distributed across the selected penetration depth. Anyone wishing to cover the entire fill height of a container as completely as possible should select the length that is closest to the actual height.Replacement tip and sample insertsA replacement tip made of V4A is available as a separate spare part for the Novartos Multi series. The corresponding sample inserts are available in five volumes ranging from 0 to 2 millilitres; for the 3-channel version, three inserts are required per zone instead of two.Choice within the Novartos rangeIf two samples per zone are sufficient, the Novartos Multi with a 2-position sample holder is the more compact alternative with fewer chambers per zone. If, instead of multiple zones, only a single target site with three samples is being tested, the Novartos Uno with a 3-position sample holder is a better fit. For a target site with two samples, the Novartos Uno with a 2-position sample holder is available.Typical industriesThe triple sample draw is primarily used where mixing processes need to be formally validated or qualified for the first time, for example in the pharmaceutical manufacture of powder mixtures or in the chemical production of granules with strict homogeneity specifications. In such cases, the quality system often requires a third, independent sample per test point, which the Novartos Multi 3-sample version provides without the need for an additional puncture.Typical areas of applicationValidation of mixing processes with three samples per zoneHomogeneity testing across multiple layers with an additional retention sampleRelease testing of large batches in drums and big bagsPharmaceutical and chemical production with increased testing requirementsTechnical detailsPipe diameter25 mmMaterialV4A stainless steel (1.4404) with components made from 1.4571Chamber length30 mmChamber width13 mmStart of the collection chamber55 mmStorageRoom temperatureOverview of variantsItem numberInsertion depth mmTotal length mmCollection zonesTotal number of socketsChamber spacing mm5358-06036008004121255358-10031,0001,2007211255358-14031,4001,600927135ContentsNovartos Multi collection lance, 3-way sample line, in the selected lengthexcluding sample inserts (available separately)Service and procurementThe choice of length depends on the insertion depth into the container and the required test scope.

Bürkle ‘Mole’ soil sampler handle with shaft, steel, 750 mm, 5350-1005
Whether a soil sampler produces usable samples depends less on the handle than on the drill head, which comes into contact with the specific type of soil. A drill head designed for sandy soil will barely penetrate heavy clay soil; conversely, a head designed for wet clay will become stuck in dry sand. The ‘Mole’ handle with pole from Bürkle is therefore deliberately designed as a basic unit only: 750 millimetres long, made of steel, without a fixed drill head. The soil conditions on site determine which of the seven available drill heads is suitable.Basic tool without drill headAt 750 millimetres in length, the handle with rod fits comfortably in the hand and transfers the necessary force into the ground when screwing in and pulling out. It is made of unalloyed steel, robust enough for repeated use in the field and for daily transport between multiple sampling points. Without a drill head attached, the unit cannot be used on its own for sampling; it forms the base onto which a suitable drill head for the respective soil type is screwed.Seven drill heads for seven soil typesBürkle supplies seven different drill heads for the Maulwurf system, each tailored to a specific soil condition, ranging from damp clay to coarse gravel. The drill head for clay and damp soils has narrow flanks to minimise friction and is suitable for damp, cohesive soils in which the material adheres well to the drill. The drill head for sand, on the other hand, has wide flanks with a larger contact surface to allow the sand to grip firmly. For very dry soils and coarse sand, the drill head for coarse sand is designed with extra-wide flanks and a wider-closing drill bit. Where strongly and weakly cohesive soils alternate within the same area, the ‘Combination’ drill head covers both properties with a single tool. For hard, encrusted and gravel-intermixed soils, the blades of the Riverside drill head extend beyond the core drill, which reduces friction during penetration. The gravel auger has slightly curved, angled blades that draw themselves downwards through the gravel, whilst stones become lodged between the flanks and finer material is retained inside. If individual stones block sampling with one of the other heads, the stone trap extracts them specifically.For the classification of soil samplesThe ‘Mole’ is used to determine soil properties, moisture content and structure directly on site, for example when surveying building sites, in agriculture or during environmental investigations. As the appropriate drill head may need to be changed depending on the soil layer, it is worth keeping several drill heads for the same handle, rather than purchasing a complete set of equipment for every soil type. On a site with varying soil types, such as from sandy topsoil to loamy subsoil, the drill head can be easily swapped on the same handle between two samples.Alternative soil samplersFor soil samples with a larger diameter or from deeper layers, LT Laborhandel also stocks the GeoSampler soil sampler made from V2A stainless steel, as well as the Pürckhauer soil sampler. Both operate on a different principle to the ‘Mole’ and, depending on the soil type and the required sample quantity, are suitable as a supplement or alternative – for example, when a larger sample quantity per puncture is required in addition to the specific soil type.Typical applicationsSoil investigation on construction sites and for building projectsAgricultural soil analysis for moisture and structureEnvironmental investigations into soil propertiesSampling at varying locations with different soil typesChecking soil structure before planting or after harvestUse by rotating teams at multiple sampling points on the same dayTechnical detailsMaterialSteel (unalloyed)Length750 mmContentsSoil sampler ‘Mole’ handle with shaftDrill head not included; must be ordered separately to suit the soil typeService and procurementLT Laborhandel can, if required, include several suitable drill bits for different soil types in a single order for the ‘Mole’ handle, ensuring that the correct bit is immediately to hand for use in varying soil layers. This also applies to companies that manage multiple sites with different soil types and wish to provide a standardised handle for all teams. If you are unsure which drill bit is suitable for the soil type in question, please contact LT Laborhandel directly for assistance.
Bürkle Immersion Bomb Sampler, brass, 1,000 ml, 5365-7000
For crude oil, fuels or heating oil, a sampler is required that operates safely in potentially explosive atmospheres whilst still sinking quickly to the bottom of a tank. The brass immersion sampler is designed specifically for these petroleum products; it is made entirely of non-sparking, nickel-plated brass and is available in two capacities: 500 and 1,000 ml.Robust housing for rapid descentThe immersion bomb’s heavy weight of 3.0 to 4.3 kg ensures that it sinks rapidly to the desired depth, even when there is a current in the tank. The upper section can be unscrewed, allowing the immersion bomb to be opened completely for cleaning. A robust carrying handle facilitates handling when lowering and raising it.Two volumes for different sample quantitiesThe smaller version (5365-7500) has a capacity of 500 ml and a total height of 300 mm, whilst the larger version (5365-7000) has a capacity of 1,000 ml and a total height of 450 mm. Both have the same external diameter of 75 mm and therefore fit through the same tank openings.Use in potentially explosive atmospheresBürkle describes the immersion bomb as tested for use in Ex protection zone 0, for explosion groups IIA, IIB and IIC. There is no certificate number or ATEX marking available for this product; the information is taken from the manufacturer’s description.Media for which the submersible pump is intendedBürkle lists crude oils, liquid petroleum products, fuels, special and test petrol, heating oils, kerosene and liquid lubricants as typical media. For more general liquid samples from tanks, tank wagons or sewage treatment works, where there is no specific focus on an Ex zone, the immersion vessel made of brass or V2A stainless steel with its EasyFlow valves offers a wider range of applications. For potentially explosive atmospheres, but with a glass container for sewage treatment plant samples, there is the glass immersion bottle, and for hard-to-reach, confined spaces, the mini immersion bomb. Anyone requiring precise sampling with a descent hose will find what they need in the Target immersion bomb.Choice of volumeIf a smaller quantity of fuel or oil is sufficient for the analysis, the 500 ml version saves weight during handling and, at 3.0 kg, is easier to manoeuvre than the 1,000 ml version, which weighs 4.3 kg. For larger-scale analyses or when several analyses are to be carried out on the same sample, the 1,000-ml version provides more capacity without the need for a second dip.Why brass in potentially explosive atmospheresBrass is a non-sparking material and is therefore the material of choice for tools and samplers used in potentially explosive atmospheres containing flammable vapours. The nickel plating provides additional protection for the surface against corrosion caused by the fuels and oils being sampled.Sampling procedureThe sampling bomb is lowered into the tank on a rope; it sinks rapidly to the desired depth under its own weight and is then pulled back out. Once the upper section has been unscrewed, the sample can be decanted directly, without any residues remaining in the housing that could compromise the next sampling.Typical areas of applicationCrude oils and liquid petroleum productsFuels, special-purpose and test petrolsHeating oils and petroleumLiquid lubricantsTechnical detailsMaterialBrass, non-sparking, nickel-platedOuter diameter75 mmRegulatory complianceTested by the manufacturer for Ex protection zone 0, explosion groups IIA, IIB, IICVariants at a glanceItem numberCapacityTotal heightHeight of collection containerWeight5365-70001,000 ml450 mm341 mm4.3 kg5365-7500500 ml300 mm195 mm3.0 kgProportion of the handle and collection container in the total heightOf the total height, 341 millimetres are accounted for by the collection container itself in the 1,000 ml version, whilst in the 500 ml version the figure is 195 millimetres. The difference between the respective total heights of 450 and 300 millimetres is accounted for by the carrying handle and the connector, which are of similar length on both versions. Anyone who needs to feed the submersible pump through a narrow tank opening should take into account not only the outer diameter of 75 millimetres but also the total height, to ensure that the unit does not catch on the edge of the opening when being lowered in.Scope of deliverySubmersible sampler (submersible bomb) in the selected volume variantService and procurementThe appropriate volume depends on the required sample quantity and the tank opening. LT Laborhandel stocks both versions of the submersible sampler individually and, if required, can also advise on how they differ from submersible vessels, submersible bottles and mini submersible samplers in the range – for example, if other liquids are sampled alongside fuels at the same site.

Bürkle EasySampler solid-material sampler, V4A stainless steel, 870 mm, 5360-0600
Free-flowing bulk materials such as fine granules or powders can be sampled quickly if the tool itself does not take up any time. The EasySampler opens its tip directly above the handle and discharges the sample immediately, without needing to be turned upside down or dismantled. The smooth, edge-free design prevents material from getting stuck in the tube and contaminating the next sample. Two lengths are available, with penetration depths of 870 and 917 millimetres, offering significantly different chamber lengths and sample volumes.Direct emptying via the handleThe handle opens the tip of the sampler, allowing the material to be emptied directly without first having to turn the EasySampler upside down or dismantle it. This saves time during repeated sampling compared to samplers that must be dismantled for emptying, for example when taking a series of spot checks from several similar bags in succession. This mechanism is not designed for viscous or pasty substances that do not flow freely; in such cases, the folding sampler for all-layer samples is more suitable.Smooth design with no sharp edgesBoth the internal and external surfaces are designed without any sharp edges, ensuring that no residual material accumulates and enters the next sample. For thorough cleaning, the EasySampler can nevertheless be easily dismantled, allowing even fine residues between two different batches to be removed without the need for special tools. For cohesive, poorly flowing powders that stick to the walls despite the smooth design, a sampler such as the Scratcher powder sampler is the more robust choice.Two lengths for different containersThe shorter version, with a total length of around 995 millimetres, achieves a penetration depth of 870 millimetres and holds 60 millilitres of sample in a single continuous chamber, which is sufficient for simple routine checks. The longer version, with a total length of approximately 1,039 millimetres, has a penetration depth of 917 millimetres and, with a 400-millimetre-long chamber, can hold up to 200 millilitres – ideal for larger sample volumes from deeper containers or when a single sample needs to suffice for several analyses at once.Rapid sampling in day-to-day operationsWhere samples are regularly taken from sacks or open containers as part of day-to-day operations, the time taken per sample is just as important as the sample quality. As the EasySampler empties without needing to be dismantled, a series of samples can be taken more quickly than with a sampler that has to be opened and reassembled each time. This also reduces the number of individual parts that can be lost or mixed up during sampling, which is a practical advantage, particularly when sampling outdoors or under time pressure.Differences from other samplers in the rangeThe EasySampler is specifically designed for free-flowing, self-flowing materials. If, on the other hand, a powder sticks to the sides or clumps together, a sampler such as the Scratcher works more reliably because it actively dislodges the material rather than simply collecting it. For viscous, paste-like substances, on the other hand, the clamshell sampler features a more suitable opening mechanism. This distinction helps in making the right choice whenever the consistency of the material to be sampled changes during operation or when several types of material are to be tested in succession.Typical areas of applicationSampling of free-flowing, self-flowing bulk materials such as fine-grained granules or powdersRapid incoming goods and intermediate checks with direct dischargeSampling in production environments where samples are changed frequentlyQuality assurance for materials that must not leave any residue in the samplerSequential sampling from several identical bags or containers in successionTechnical detailsMaterialV4A stainless steel (1.4404)Sampling methodFull-thickness sample/cross-section sampleSuitable sample materialflowable, free-flowingDesignHandle-operated tip, no rear edges, can be dismantledOverview of variantsItem numberPenetration depth mmSample volume mlChamber length mmTotal length mmEAN5360-06008706010099540677220139745360–10009172004001,0394067722013981ContentsEasySampler sampler for solids in the selected lengthService and procurementThe appropriate length depends on the container height and the required sample quantity.

Bürkle Qualification Sampler Set, PP/PTFE, with carrying case, 5330-1000
Anyone who needs to take samples of both low-viscosity and high-viscosity media on site usually requires two different samplers, each with its own container. The Quali Sampler Set combines a LiquiSampler and a ViscoSampler with five sample bottles and a cleaning brush in a 121 cm long carrying case, so that both samplers are stored together, ready for use in the field.Two samplers for different viscositiesThe LiquiSampler in the set is designed for low-viscosity media, whilst the ViscoSampler is designed for more viscous liquids; both are the 100-cm version. This means the set covers a wider viscosity range than a single sampler could, without the need to carry a separate device for every application.Five bottles and a cleaning brush in the caseThe scope of delivery includes five 100 ml HDPE bottles for direct filling on site, as well as a cleaning brush that can be used to clean both samplers between samples to prevent carry-over. The carrying case measures 121 x 22 x 11 cm and holds all the components required for on-site use.Materials: PP, PTFE and other plasticsThe plastic components of the two samplers consist, amongst other things, of polypropylene and polytetrafluoroethylene, supplemented by fluoroethylene-propylene, polyvinylidene fluoride, aluminium and a seal made of acrylonitrile-butadiene rubber. Bürkle provides a material declaration for these materials, listing the individual plastics used in the ViscoSampler and LiquiSampler ranges.Individually or as a setAnyone who only requires one of the two sampler types, or needs a different length, will find the individual products available as the ViscoSampler PP and in a PTFE/FEP version. For smaller sample volumes with a similar design, the Mini ViscoSampler is also available. The Quali Sampler Set, on the other hand, is ideal for anyone who wishes to have both sampler types to hand in the same case.A case for field useInstead of transporting two samplers separately and organising a separate storage space for each, the case keeps both devices, the five bottles and the cleaning brush together in one fixed place. This reduces the risk of forgetting a necessary item on site, particularly for appointments outside one’s own laboratory.Cleaning between two sample typesThe cleaning brush provided is used to remove residues from the LiquiSampler and ViscoSampler between two sampling sessions. This is particularly important when sampling different batches or media in succession and it is essential to prevent carry-over from one sample to the next.Five bottles for multiple samples in a single sessionWith five 100 ml HDPE bottles, several samples can be collected during a single field visit without having to empty and reuse the bottles in between. This saves time on site and keeps the individual samples cleanly separated from one another until they are analysed in the laboratory.Who will benefit from this setThe Quali Sampler Set is designed for anyone working in the field or in mobile quality control who does not know in advance whether they will be dealing with low-viscosity or higher-viscosity media. On the other hand, those who regularly sample only one viscosity class will often find that one of the individual products is sufficient, without needing the additional equipment included in the set. For teams visiting multiple sites or customers in a single day, the fixed configuration in the case also reduces the hassle of having to reassemble the correct equipment before every appointment.Typical areas of applicationOn-site qualitative sampling of liquids with varying viscositiesField assignments where a complete sampling kit in a case is requiredVarying sample types that require both a Liqui-Sampler and a ViscoSamplerEquipment for field service or mobile quality controlTechnical detailsLength121 cmWidth22 cmHeight11 cmMaterialPolypropylene (PP), polytetrafluoroethylene (PTFE), fluoroethylene-propylene (FEP), aluminium, polyvinylidene fluoride (PVDF), acrylonitrile-butadiene rubber sealContentsLiquiSampler, 100 cmViscoSampler, 100 cmCarrying case5 x HDPE bottles, 100 mlCleaning brushService and procurementBürkle also stocks a second version of the Quali Sampler; LT Laborhandel can advise on the most suitable configuration for your specific application.

Bürkle SiloBohrer Tank and Silo Sampler, V2A stainless steel, 1,500 mm penetration depth, 5301-2000
Moist bulk materials, corrosive cleaning agents or strict hygiene requirements place greater demands on a sampler than dry, neutral material. The SiloBohrer V2A is the tank and silo sampler version made from V2A stainless steel (1.4301), designed specifically for these conditions: 1,500 mm penetration depth, a smooth, easy-to-clean surface and resistance to a wide range of chemicals.V2A stainless steel: corrosion-resistant and hygienicV2A stainless steel (1.4301) withstands moisture, many acids, alkalis and cleaning agents significantly better than aluminium and retains its shape even with frequent contact with aggressive media. The smooth surface can be thoroughly cleaned and disinfected, which is an advantage wherever cross-contamination between batches must be avoided. This makes the V2A Silo Drill suitable for use in the food, pharmaceutical and chemical industries, where hygiene and material resistance are important factors beyond mere sampling.Construction: identical dimensions, more robust materialThe tube diameter, outer diameter and collection chamber correspond to those of the aluminium version: 40 mm tube diameter, 90 mm outer diameter at the tip, a collection chamber 300 mm long and 32 mm wide, which begins 123 mm behind the tip and holds 400 ml of sample material. With a total length of 1,524 mm, the SiloBohrer V2A weighs 5.9248 kg, around 1.8 kg more than the aluminium version. Given the more robust material and the greater resistance to abrasive particles, this is a reasonable trade-off in terms of weight.When V2A stainless steel is worthwhileWhere tanks and silos are regularly cleaned and disinfected, or where sample material comes into contact with chemicals, the greater material resistance of V2A stainless steel pays off. If, on the other hand, the bulk material is dry and not very aggressive, and budget is the main consideration, the lighter and more affordable aluminium version of the SiloBohrer is the suitable alternative, offering identical dimensions and collection volumes.A representative sample rather than a snapshot from aboveIf a silo is sampled only from the surface, the sample often reflects only the most recently filled layer. Moisture, clumping or chemical residues often only become apparent in deeper layers. With a penetration depth of 1,500 mm, the SiloBohrer V2A reaches a zone where such effects are more likely to be detected than at the surface, thereby providing a more reliable basis for quality assessment.A single chamber or multiple zones simultaneouslyThe single collection chamber of the SiloBohrer V2A is sufficient for a single spot sample taken at a defined depth. However, if several layers are to be sampled in a single operation – for example, to document segregation across the entire height of the container – a multi-stage sampler such as the Multi-Collector is the more suitable solution.Cleaning between two batchesThe smooth stainless steel surface of the SiloBohrer V2A can be quickly wiped down or treated with cleaning agents between sampling operations without damaging the polish or material structure. This is a practical advantage, particularly when there are frequent batch changes within the same silo or tank, compared to materials that are more sensitive to aggressive cleaning agents. Residues can thus be completely removed before the sampler is inserted into the next batch.Classifying V2A stainless steel as a materialStainless steel 1.4301 contains chromium and nickel, which form a passive protective layer on the surface, making the material resistant to many everyday chemicals. Unlike aluminium, this protective layer remains stable even with frequent contact with cleaning agents or slightly acidic media, which explains the higher cost and weight compared to the aluminium version.Typical areas of applicationSampling from tanks and silos in the food, pharmaceutical and chemical industriesMoist or corrosive bulk materials that require frequent cleaning of the samplerFacilities with high hygiene requirements for sampling equipmentSampling of abrasive particles that place greater strain on the materialTechnical detailsMaterialV2A stainless steel (1.4301)Penetration depth1,500 mmOverall length1,524 mmPipe diameter40 mmOuter diameter90 mmNumber of collection openings1Sample volume per chamber400 mlTotal sample volume400 mlChamber length300 mmChamber width32 mmStart of the collection chamber123 mmNet weight5.9248 kgContents of deliveryTank and silo sampler SiloBohrer V2AService and procurementFor greater penetration depths or silos that are difficult to access, LT Laborhandel recommends the PowderProof vertical sampling lance.

Bürkle folding core sampler for multi-layer samples, V4A stainless steel, 500 mm, 5359-1600
Paste-like and porridge-like substances often settle in a barrel or bucket in distinct layers: a thinner upper layer and a thicker lower layer. An open-top sampler easily smears these layers when the sample is extracted. The folding sampler for all-layer samples is designed precisely for this purpose; its opening mechanism keeps the layers separate whilst the sample is being taken and can be completely dismantled for cleaning. Two lengths are available, with penetration depths of 500 and 750 millimetres, suitable for both shallower buckets and deeper drums.Folding mechanism for viscous and paste-like mediaUnlike a simple tube sampler, the folding sampler opens and closes via a dedicated mechanism designed for tough, paste-like substances. It remains closed during sampling; at the desired depth, it opens and collects the sample across the entire cross-section. According to Bürkle, the mechanism is optimised so that it remains easy to operate even after contact with sticky media. This mechanism is not necessary for free-flowing, self-flowing solids; in such cases, the simpler EasySampler is sufficient.Fully dismantlable for cleaningThe entire folding sampler can be dismantled for cleaning, which is important when dealing with sticky, paste-like media to ensure no residues end up in the next sample. The 34-millimetre diameter provides a sufficiently wide opening to accommodate even viscous substances without clogging, whilst remaining narrow enough for most standard drum openings. For cohesive powders – which, whilst not liquid, are also difficult to homogenise – the Scratcher powder sampler may be the more suitable alternative.Two lengths for different containersThe shorter version, with a total length of 550 millimetres, has a penetration depth of 500 millimetres and can collect around 300 millilitres of sample, which is sufficient for most routine analyses. The longer version, with a total length of around 833 millimetres, has a penetration depth of 750 millimetres and a sample volume of 460 millilitres, suitable for deeper drums or buckets. Both lengths have the same tube diameter of 34 millimetres, so the choice of version depends solely on the required penetration depth.Compliance with DIN standardsThe folding sampler complies with DIN 51750 Part 3 for the sampling of solid fuels, as well as DIN EN ISO 15528 for coating materials, paints and varnishes. Both standards set out requirements for the sampling of viscous and pasty substances, as is customary in the respective industries. For businesses that are required to document their sampling in accordance with one of these standards, this serves as proof that the design and handling of the folding sampler are specifically tailored to meet these exact requirements.Distinction from other samplers in the rangeThe folding sampler specifically covers the range between free-flowing bulk materials and completely liquid media. For free-flowing, dry solids, the EasySampler is the quicker choice; for low-viscosity to moderately viscous liquids, the liquid collectors with thumb or screw-top openings are more suitable. This clear distinction simplifies the selection process when different consistencies need to be sampled within the same facility, without having to test a new tool for each substance.Typical applicationsSampling of viscous, pasty and paste-like substances from drums and bucketsQuality control in chemical and food production for viscous productsIncoming goods inspection of layered, non-free-flowing materialsProcess control where layers would otherwise mix if a simple puncture were usedSampling of paints, varnishes and coating materials in accordance with DIN EN ISO 15528Technical detailsMaterialV4A stainless steel (1.4404)Sampling methodFull-thickness sampleSuitable sample materialpaste-like, highly viscousDesignFolding mechanism, can be completely dismantledOuter diameter / Tube diameter34 mmStandardsDIN 51750 Part 3, DIN EN ISO 15528Variants at a glanceItem numberInsertion depth mmSample volume mlOverall length mmEAN5359-160050030058340677220139505359-18007504608334067722013967ContentsFolding corer for all-layer samples in the selected lengthService and procurementThe appropriate length depends on the height of the container from which the paste-like or slurry-like substance is extracted. LT Laborhandel stocks both lengths separately and can advise on the distinction between these and samplers for free-flowing solids.

Bürkle Profi Sampler Vacuum Sampling Pump, Aluminium, GL 45, 5305-1100
Solvents and other flammable liquids must not generate any electrostatic charge during sampling. The Profi Sampler Aluminium is a vacuum sampling pump designed specifically for this purpose, suitable for explosion groups IIA, IIB and IIC, and included in the scope of delivery is a grounding cable to earth the unit before sampling.Aluminium, glass and electrically conductive suction tubesThe pump housing is made of aluminium; the 500 ml sample bottle is made of glass and connected via a GL-45 thread, compatible with standard Schott glass bottles ranging from 100 ml to 1,000 ml. Five black, electrically conductive polyamide suction tubes, each 220 cm long, are included in the Scope of delivery, as is a brass hose weight.Earthing as a prerequisite for safe useBürkle expressly points out that the device must be earthed when sampling flammable liquids. The earthing cable included in the Scope of delivery fulfils this requirement; in addition, depending on the application, the manufacturer recommends an anti-static kit, which is not included in the Scope of delivery. The explosion protection note refers to the specified explosion groups and the requirement for earthing. Bürkle does not state an ATEX marking for the device; according to the manufacturer, it is suitable for Ex zones 0, 1 and 2.Aluminium or PP: the right versionFor solvents and flammable liquids requiring explosion protection, the aluminium version with a GL-45 glass bottle is the correct choice. Where, on the other hand, weak acids, alkalis or aqueous cleaning agents without a risk of explosion are involved, the Profi-Sampler version made of polypropylene with a PP bottle and PE suction hose meets these requirements. Both pumps draw the sample using the same vacuum principle, achieving a suction height of up to 5 mWS for media with a viscosity of up to 500 mPa·s.Why glass rather than plasticWith solvents, a plastic bottle may corrode the medium or, conversely, leach components into the sample, which would distort the analysis result. The 500-millilitre glass bottle with a GL-45 thread avoids this risk and is compatible with standard Schott glass bottles ranging from 100 ml to 1,000 ml, meaning that different bottle sizes can be connected depending on the required sample volume.Seal for tamper-evident verificationAs with the PP version, seal-it bottle seals secure the glass bottle tamper-proof after sampling. 20 seals are included to ensure the sample’s journey from the collection point to the laboratory remains traceable, a particularly important consideration for flammable or safety-critical samples.Electrically conductive suction tubes instead of tubingUnlike the PP version with a flexible suction hose, the Profi Sampler Aluminium uses five rigid, electrically conductive suction tubes made of polyamide, each 220 cm long. The electrical conductivity of the tubes, together with the earthing cable, helps to prevent electrostatic charging when drawing in flammable liquids.Five suction tubes for continuous operationAs five suction tubes are included in the Scope of delivery, a replacement is immediately available should a tube become worn or damaged, without the need to interrupt sampling whilst awaiting a replacement. This is a practical advantage in safety-critical applications with explosion-proof requirements, as damaged tubes that are no longer continuously conductive should be replaced before they are used further. Replacement tubes can be reordered separately if required.Typical applicationsSampling of solvents and other flammable liquidsFacilities where explosion groups IIA, IIB or IIC are relevant during samplingFilling directly into Schott glass bottles ranging from 100 ml to 1,000 mlSampling where earthing of the sampler is mandatoryTechnical detailsMaterialAluminium (pump), glass (bottle), polyamide (PA, suction tubes), brass (MS, hose weight)ThreadGL 45, internal threadSuction tube length220 cmBottle capacity500 mlViscosity up to500 mPa·sSuction height5 mWSNet weight3.944 kgScope of deliveryAluminium vacuum pump with support legs, vent valve and GL 45 bottle threadGlass bottle, 500 ml5x black PA suction tubes, 220 cm, electrically conductiveHose cutterBrass hose weight20x ‘Seal-it’ bottle sealsEarthing cableService and procurementFor use with flammable liquids, the manufacturer also recommends an anti-static kit, which is not included in the Scope of delivery. LT Laborhandel can assist with the procurement of spare parts such as suction tubes, bottle seals or replacement bottles in the appropriate GL-45 format. Anyone who samples aqueous media without a risk of explosion in addition to solvents should supplement their equipment with the PP version of the Profi Sampler, ensuring that a suitable device is available for both types of media.
