Macherey-Nagel pleated filter MN 616 md, high-quality, 4–7 µm (Ø 55–500 mm)
For finer particulate matter: Macherey-Nagel MN 616 md pleated filter Macherey-Nagel MN 616 md pleated filters are the right choice when standard filters (such as the MN 615) reach their limits. In this quality grade, the abbreviation ‘md’ stands for a slightly higher density and improved retention capacity. These are high-quality filter papers that are machine-pleated (1/4-fold) so that they can be inserted into the funnel straight away. The difference: medium-speed to slow In everyday laboratory work, it often happens that fine-grained precipitates pass through a standard filter (leaving the filtrate cloudy). This is where the MN 616 md comes into its own: Filtration rate: At approximately 55 seconds (in accordance with DIN 53137), this paper filters about half as fast as the standard MN 615 type. This reduced flow rate is necessary to reliably retain finer particles. Retention capacity: The pore size range is 4 to 7 µm. This ensures that fine precipitates such as barium sulphate (cold-precipitated), tin oxide or sugar solutions are reliably clarified. Surface: The filters are smooth, which enables good recovery of the precipitate. Advantages of pleated filters Despite the finer pore structure, you benefit from the pleated geometry. The large surface area prevents the filter from becoming clogged quickly, which is often a problem with flat circular filters of the same density. You obtain a clear filtrate within a reasonable time. Quality and purity The MN 616 md grade is made from high-quality cellulose with a very high proportion of alpha-cellulose. The ash content is < 0.1 per cent, which makes the paper virtually chemically inert. It is perfectly suited to qualitative analyses in chemistry, biology and food monitoring. Available sizes We offer this speciality paper in a comprehensive range, from small 55 mm filters for micro-funnel applications right up to the 500 mm large format for technical applications. Areas of application Analytical: Filtration of fine precipitates (e.g. calcium oxalate, magnesium ammonium phosphate). Beverage industry: Clarification of wine, beer or juices in cases of fine turbidity. Electroplating: Bath maintenance for fine suspended solids. Environment: Soil analysis and water treatment. Technical data Type: MN 616 md (pleated filter) Type: High-quality filter paper Filtration rate: Medium-fast to slow (approx. 55 s) Surface: Smooth Basis weight: 85 g/m² Thickness: 0.17 mm Retention range: 4–7 µm (fine particles) Ash content: approx. 0.1 % Material: Cellulose Format: folded into quarters Packaging unit: 100 pieces per pack Contents 1 x pack of 100 Macherey-Nagel pleated filters (type MN 616 md) (The diameter corresponds to the variant you selected above.) Custom requirements & accessories When should you choose MN 616 md instead of MN 615? Opt for MN 616 md if your filtrate is still cloudy when using MN 615. Switch back to MN 615 if filtration with MN 616 md takes too long and the filtrate is already clear enough. Do you need funnels, stand fittings or beakers to collect the filtrate? We can fully equip your workstation. Please contact our procurement service.

Macherey-Nagel pleated filter, type MN 617, high quality, fast-filtering (Ø 55 mm – 500 mm)
Macherey-Nagel MN 617 pleated filters represent a system solution optimised in terms of materials science and highly efficient in terms of geometry, designed for rapid clarification, coarse particle separation and general sample preparation in day-to-day laboratory work. Available in an extremely wide range of diameters, from 55 mm for small-scale analytical batches up to large-area 500 mm filters for high-volume separation processes, this filter series caters for every scale of modern laboratory processes. For routine filtration in food analysis, environmental chemistry or industrial quality control, the structural purity and fibre stability of the filter paper are the primary criteria for clarifying media in a way that is gentle on the material, contamination-free and process-reliable. Maximum filtration rate thanks to pre-pleated geometry The design and fluid-mechanical foundation of this series lies in its ready-to-use pleated structure. Unlike traditional round filters, which must first be laboriously folded twice before being inserted into the funnel, the pre-formed pleat pattern multiplies the effective filtration surface area. This leads to a drastic reduction in filtration times during daily high-throughput operation. With a standardised filtration rate of approx. 9 seconds according to the manufacturer’s specification, the MN 617 grade enables an extremely rapid liquid throughput. Flow resistance is minimised, thereby gently reducing unwanted blocking effects in viscous or particle-rich sample flows. High wet tear strength and the purest raw material base From a materials science perspective, the MN 617 grade is based on refined pulp and high-quality linters, which are processed entirely free from chemical binders or additives. The smooth surface structure ensures a homogeneous non-woven fabric that exhibits excellent inherent mechanical stability. Thanks to optimised fibre entanglement, the filters possess remarkable wet tear strength. They withstand the fluid-mechanical pressure during funnel filtration without damage and do not tend to release fibres into the filtrate. With a typical ash content of approximately 0.1 per cent, the paper is perfectly suited to qualitative analytical procedures where ash-free incineration is not strictly required. Cost-effective routine use and full GLP compliance The infrastructural validity of the MN 617 pleated filters is demonstrated by their reliability in recurring routine tasks. As the filters are supplied pre-pleated and ready for use, laboratory staff save valuable working time whilst simultaneously minimising the risk of contamination from manual folding. For laboratory managers and quality management officers in regulated B2B environments, Macherey-Nagel’s range provides a reliable basis for documentation and validation, enabling recurring test processes and certifications to be carried out reliably in accordance with GLP guidelines. Technical details Material Science & Filter Structure Filter type: High-quality filter paper / pleated filter (pre-configured and ready for use) Grade / Quality level: MN 617 Material basis: Refined alpha-cellulose and the purest linters Binder status: 100 per cent binder-free (free from chemical additives) Surface structure: Smooth Filtration properties: Fast filtration (open-pored structure for coarse precipitates) Filtration rate: approx. 9 seconds (standardised according to manufacturer’s specifications) Ash content: approx. 0.1 per cent (qualitative classification) Physical properties & dimensions Basis weight: approx. 85 grams per square metre (85 g/m²) Filter thickness: approx. 0.22 mm (millimetres) Available diameter range: 55 mm to 500 mm Diameter variants in the range: 55, 70, 90, 110, 125, 150, 185, 240, 270, 320, 385, 400, 450, 500 mm Resistance & Compliance Chemical resistance: Inert to mild acids, alkalis and a wide range of organic solvents Wet tear strength: High (structurally stable under liquid load) Quality management: Supports standardised, reproducible routine filtration processes in accordance with GLP Contents 1 x pack of Macherey-Nagel pleated filters, grade MN 617, high-quality and fast-acting (standard contents: 100 pieces per box) in the diameter selected by the customer (55 mm to 500 mm).

Macherey-Nagel MN 619 round filter: high quality, slow-filtering, smooth (Ø 55 mm – 500 mm)
The Macherey-Nagel MN 619 round filters represent a structurally optimised and process-proven system solution for high-quality filtration in everyday laboratory work. Available in a wide range of diameters, from 55 mm for compact standard funnels up to 500 mm for high-volume separation processes, this filter series caters for every scale in chemistry, pharmaceuticals, environmental analysis and industrial quality control. Wherever fine-particle suspensions need to be clarified or demanding samples pre-isolated, this slow-filtration quality guarantees gentle handling of materials, particle-free results and reliable process performance. Maximum particle retention thanks to a dense fibre structure The technological foundation of the MN 619 round filters is based on refined cellulose and linter fibres, which are processed into a homogeneous, close-meshed structure. The slow filtration rate of around 100 seconds (according to the manufacturer’s specifications), from which the filter takes its name, results from the high density of the pore structure. This geometric structure ensures that even fine crystalline precipitates and microparticles are reliably retained on the filter surface. The risk of a transient particle flow through the filter medium is thus effectively minimised, which reliably safeguards the validity of subsequent qualitative analyses. Smooth surface geometry for residue-free separation From a materials science perspective, the completely smooth surface of the round filter offers significant functional advantages in sample preparation. Unlike creped variants, fine precipitates on the smooth structure do not tend to become lodged in fibre recesses. This noticeably facilitates the subsequent mechanical removal or washing out of the filter cake. Furthermore, the material is characterised by high purity and a low ash content typical of high-quality filter papers, thereby gently preventing unwanted chemical interactions with the sample medium or solvent extractions. High wet strength for reproducible laboratory processes Despite being based on pure cellulose without synthetic stabilisers, the MN 619 round filters exhibit remarkable inherent mechanical stability when wet. The three-dimensional depth structure remains completely dimensionally stable even under the hydrostatic pressure of a fully filled funnel. For laboratory managers and quality management personnel in regulated environments, Macherey-Nagel offers, with this standardised fibre grade, a reliable and audit-compliant documentation basis for carrying out recurring routine filtrations in accordance with GLP guidelines in an error-free and reproducible manner. Technical details Material Science & Filter Structure Filter type: Qualitative round filter / paper filter Grade / Quality level: MN 619 Material composition: High-purity cellulose and refined linter fibres Surface texture: Smooth, uniformly structured Colour: White Filtration rate: Slow (approx. 100 seconds according to the manufacturer’s specifications) Intended use: Separation of fine-crystalline and very fine precipitates Physical properties Weight per unit area: approx. 85 grams per square metre (85 g/m²) Filter thickness: approx. 0.17 mm (millimetres) Fibre shedding: Extremely low due to dense fibre bonding Chemical resistance: Inert to mild acids, alkalis and common organic solvents Dimensions & range of variants Available diameter range: 55 mm to 500 mm Common diameters: 55, 70, 90, 110, 125, 150, 185, 240, 320, 400, 500 mm Cut: Geometrically precise, fibre-free circular cut Hazard classification: Not classified as a hazardous substance under GHS guidelines; safe to handle Contents 1 x pack of Macherey-Nagel glass fibre round filters, quality MN 619, smooth (standard contents: 100 pieces per box) in the diameter selected by the customer (55 mm to 500 mm).

These are high-quality filter papers designed for general separation tasks where the filter residue does not need to be determined gravimetrically (no ash-free ignition required). This product range is characterised by its versatility: it is available in numerous diameters ranging from 25 mm to 500 mm, thus covering every funnel size – from the smallest micro-funnel right through to large industrial filtration units. Features: The happy medium The MN 615 grade is the standard for routine filtration. It offers the ideal balance between time savings and particle retention: Filtration speed: Classified as medium-speed filtration (approx. 22 seconds according to DIN 53137), the paper enables rapid processing without clogging. Surface: The filters are smooth. This makes it considerably easier to scrape off or recover precipitates from the filter cake. Retention capacity: With a pore size range of approx. 4 to 12 µm, medium-fine to coarse precipitates (such as sulphides, bichromate or calcium oxalate) are reliably retained. Quality and purity Macherey-Nagel uses high-quality raw materials for these filters. They consist of approximately 95 per cent alpha-cellulose, which ensures high chemical stability. The ash content is extremely low at approximately 0.1 per cent. This means the filters are chemically almost inert and do not contaminate your filtrates. Areas of application Routine laboratory work: clarification of buffer solutions and reagents. Education: Standard filters for schools and universities (qualitative analysis). Food industry: Filtration of extracts and juices. Electroplating & metalworking: Bath maintenance and analysis. Select the correct diameter Simply select the diameter that fits your funnel from the menu above.

The VISOCOLOR SCHOOL analysis kit brings hands-on water analysis straight into the classroom: all the reagents included are approved in accordance with the GUV regulations for handling hazardous substances in the classroom (GUV-SR 2004) – pupils can therefore carry out the experiments themselves without teachers having to intervene at every step. A safe introduction to water analysis for the classroom Whether in chemistry, biology or geography lessons: water analysis is an integral part of many curricula when it comes to topics such as water quality, nutrient inputs or ecosystems. The VISOCOLOR SCHOOL analysis kit makes such experiments suitable for everyday use – for example, when analysing water samples from a nearby stream, pond or lake as part of a field trip, or directly in the classroom using samples brought in by the pupils. As the reagents comply with GUV-SR-2004, even younger pupils can carry out titrations and evaluate colour comparisons themselves under supervision. Ammonium and pH – two parameters of high educational value The kit covers the determination of ammonium (range 0 / 0.2 / 0.5 / 1 / 3 mg/L NH₄⁺) and pH (range 4.0 / 5.0 / 6.0 / 7.0 / 8.0 / 9.0). Both parameters are ideal for teaching pupils fundamental concepts: ammonium as a classic indicator of organic pollution and nutrient inputs into water bodies, and pH as a key parameter for virtually any chemical and biological analysis of water. The kit includes a case, test kits, accessories and instructions – ready to use for your next lesson. Ready for immediate use without a photometer Analysis is carried out purely visually by colour comparison, without the need for an additional photometer.

Macherey-Nagel pleated filter MN 615, high quality, medium-speed (Ø 70–500 mm)
Efficiency in the laboratory: Macherey-Nagel MN 615 pleated filters Macherey-Nagel MN 615 pleated filters are the time-saving solution for daily laboratory routines. Unlike simple round filters, which have to be laboriously folded by hand (quarter-fold) before being placed in the funnel, these filters are already machine-folded (1/4-fold). This not only saves valuable working time but also offers a decisive technical advantage: the pleated structure significantly increases the effective filter surface area. The result is a faster flow rate and a reduced tendency to clog, as the precipitate is distributed more evenly. The all-rounder for qualitative analyses The MN 615 grade is the globally proven standard paper for qualitative analyses (ash content approx. 0.1 per cent), which primarily involve the clarification of solutions or the recovery of filtrates. Medium-speed filtration: With a filtration time of approx. 22 seconds (according to DIN 53137), this paper offers the ideal balance between speed and retention. Smooth surface: The fibres are processed to form a homogeneous structure that reliably retains particles. Retention range: Particles ranging from 4 to 12 µm (e.g. lead sulphide, calcium oxalate) are reliably filtered. Wide range of sizes We offer the MN 615 pleated filters in a wide range of diameters – from 70 mm for small analytical funnels up to 500 mm for large-scale production batches. Please note that the diameter specified always refers to the diameter of the unfolded paper disc. Areas of application General chemistry: Clarification of salt solutions and buffers. Food analysis: Filtration of macerates, juices or extracts. Schools & Education: Time-saving preparation of school experiments. Environmental analysis: Pre-filtration of water samples. Technical data Type: MN 615 (folded filter) Type: Qualitative filter paper Filtration rate: Medium-fast (approx. 22 s) Surface: Smooth Basis weight: 70 g/m² Thickness: 0.16 mm Retention range: 4 – 12 µm Ash content: approx. 0.1% Material: Cellulose (approx. 95% alpha-cellulose) Format: folded into quarters (ready for the funnel) Packaging unit: 100 pieces per pack Contents 1 x pack of 100 Macherey-Nagel pleated filters (type MN 615) (The diameter corresponds to the variant you selected above.) Custom requirements & accessories Do you have the right funnel for your pleated filters? Rule of thumb: The top edge of the pleated filter should end approx. 1–2 cm below the rim of the funnel. A filter that is too large will protrude (risk of evaporation, tendency to creep), whilst one that is too small will not make full use of the funnel’s volume. Alternatives: If you need to filter very fine precipitates (e.g. barium sulphate), we recommend the denser type MN 619. For very coarse, bulky precipitates, opt for type MN 617. Do you require large quantities for industrial use or special sizes? Please contact our procurement service.
Macherey-Nagel MN 85/90 BF round glass fibre filter, binder-free, 0.5 µm (Ø 5 mm – 270 mm)
Macherey-Nagel MN 85/90 BF glass fibre round filters represent a high-purity, matrix-stable system solution for demanding filtration processes, gravimetric analyses and the highly efficient separation of ultrafine particles in laboratories, environmental analysis and industrial quality control. Manufactured from 100% pure borosilicate glass fibres without any organic or inorganic binders (BF=binder-free), these depth filters guarantee absolute chemical inertness and contamination-free analytical results. The wide range of available diameters, from a delicate 5 mm up to a large-area 270 mm, enables perfect scalability for all standard Nutsch, extraction and micro-weighing equipment. Material-science purity and binder-free structure The process-engineering heart of the MN 85/90 BF filters is their binder-free fibre architecture. As no chemical additives or acrylic resins are used at all during manufacture, the filter matrix remains absolutely stable even when filtering highly aggressive organic solvents, strong acids or alkaline media. Any leaching of foreign substances from the material into the filtrate – which could interfere with sensitive downstream detection methods (such as HPLC, GC or ion chromatography) – is reliably prevented in a manner that is gentle on the material and ensures process reliability. Furthermore, the high purity of the borosilicate fibres ensures complete biological inertness, which makes them ideal for use in microbiology and cell culture filtration. Excellent retention capacity and outstanding fluid dynamics With a nominal retention capacity of 0.5 µm in liquid media, these glass fibre filters are ideally suited for the separation of the finest precipitates, colloidal suspensions and proteins. The three-dimensional depth filter structure not only traps particles on the surface but also traps them within the fibre mesh. This results in an exceptionally high dirt-holding capacity and prevents premature clogging of the filter, even with samples containing high levels of matrix material such as wastewater, slurries or extracts. At the same time, excellent flow rates are achieved, which significantly reduces filtration times in multi-user operation. Extreme thermal resilience and versatile environmental analysis From a thermodynamic perspective, the MN 85/90 BF round filters are characterised by outstanding temperature resistance of up to 500 degrees Celsius. This thermal stability makes them ideal for standard gravimetric methods, such as the determination of filterable substances (dry residue) and loss on ignition in accordance with national and international environmental standards. The filters can be dried in a drying oven or ashed in a muffle furnace without any risk of the fibre structure collapsing. Typical areas of application include not only wastewater and drinking water monitoring but also air pollution control, the protection of membrane filters against clogging (pre-filtration) and the clarification of viscous phases. Technical details Metrology & Filter Specifications Filter type: Glass fibre round filter / depth filter Quality / Grade: MN 85/90 BF Binder: 100% binder-free (BF) Nominal retention capacity (liquid): 0.5 µm Retention capacity (air/gas): Higher (due to diffusion and interception mechanisms) Filtration characteristics: Very high flow rate with maximum particle retention Material properties & resilience Base material: High-purity borosilicate glass fibre mesh Chemical resistance: Universally resistant to organic solvents, acids and mild alkalis Thermal stability: Up to 500 degrees Celsius (completely incinerable/refractory) Biological reactivity: Inert (no breeding ground for microorganisms) Dimensions & Range of Variants Available diameters: 5 mm to 270 mm (selectable according to application) Filter shape: Round filters (pre-cut, flat) Packaging: Usually supplied in a handy cardboard box (quantity varies depending on diameter, usually 100 pieces) Contents 1 x pack of Macherey-Nagel MN 85/90 BF round glass fibre filters in the selected diameter variant 1 x batch-specific quality certificate from the manufacturer Important note: Vacuum filtration units, Büchner funnels, suction flasks and suitable rubber sleeves (Guko) are not included in the scope of delivery and must be selected separately to suit the specific workstation. Individual requirements & accessories To realise the full potential of the Macherey-Nagel MN 85/90 BF filters, their use in professional vacuum filtration set-ups is recommended. Our laboratory range includes suitable porcelain and stainless steel Büchner funnels, as well as glass filtration apparatus with frit supports. For the precise handling of damp round filters without damaging the fibre structure, we recommend the use of rounded stainless steel laboratory tweezers. Should you require filters with a different retention capacity or integrated organic binders for your analytical work, we also offer the complete Macherey-Nagel filter range (e.g. MN 85/70 or membrane filters). Please make use of our technical procurement service to design your filtration workstations to suit your specific requirements.

Macherey-Nagel NANOCOLOR VARIO Mini Thermoblock, 6 positions, portable, 919380
Anyone who has to digest water samples not in the laboratory but directly on site at the watercourse, at the sewage treatment works or at the customer’s premises is familiar with the problem: without a mains power supply and fixed laboratory equipment, it is virtually impossible to carry out a COD or nitrogen digestion. The Macherey-Nagel NANOCOLOR VARIO Mini thermoblock solves exactly that problem. It can be powered via a 12-volt car socket and, with its compact dimensions of 170 x 105 x 125 mm, fits into any boot or fieldwork bag. As the smallest and most affordable model in the NANOCOLOR VARIO range, it is the ideal entry-level solution for anyone who needs to digest samples occasionally or whilst on the move, without having to invest in a large benchtop unit straight away. Mobile operation without laboratory infrastructure The 12 V, 5 A and 60 W power supply allows connection to a vehicle’s on-board electrical system. This makes the thermoblock a mobile companion for on-site sampling, for example at water bodies, sewage treatment works or construction sites, where no laboratory mains supply is available. Weighing 1,450 g (gross) and with its compact dimensions, the unit can be transported with minimal effort, stowed in a vehicle and set up and made ready for use within a few minutes. Precise temperature control in accordance with standards, even on the move Six boreholes with an external diameter of 16 mm accommodate the cuvette tests. Six fixed temperature settings (70 °C, 100 °C, 120 °C, 148 °C, 150 °C and 160 °C) cover the standard digestion procedures in accordance with DIN, EN, ISO and EPA methods, with a temperature stability of ±1 °C to ensure reproducible results. Even outside the laboratory, there is no need to compromise on accuracy; results obtained in the field are comparable to those from a stationary digestion process. Simple operation and update capability Menu navigation is via an illuminated graphical LCD display with 128 x 64 pixels and four buttons with icon-based navigation, which is intuitive to use even in field conditions whilst wearing gloves or in changing light conditions. Free software updates can be installed via the mini-USB OTG interface, either via a PC and the internet or directly via a USB stick. Internal quality control is possible using the optionally available T-Set adaptors (919917 or the USB version 919921). The removable protective cover is secured magnetically, whilst overheating protection ensures additional operational safety during mobile use. Safe for field use Despite being designed for mobile use, the VARIO Mini meets CE requirements and is rated for an ambient temperature range of 10 to 40 °C and a maximum relative humidity of 80 per cent (non-condensing). The integrated overheating protection and the magnetically secured protective cover ensure that the thermoblock can be operated safely even outside controlled laboratory conditions. Position within the NANOCOLOR VARIO family In addition to the Mini, the NANOCOLOR VARIO range from Macherey-Nagel comprises four further thermoblocks for different requirements: the single-block VARIO C2 with 12 positions for everyday laboratory use, the VARIO C2 M with additional 22-mm bores for larger digestion vessels, the VARIO 4 with two independently controllable blocks for high throughput, and the VARIO HC with active cooling for shorter cycle times. Those who regularly process larger sample batches in the laboratory are better served by one of these benchtop models; in terms of sheer sample capacity, the Mini, with its 6 positions, has been deliberately kept compact. The VARIO Mini remains the right choice when mobility, low weight and an affordable entry-level price are the key priorities. Typical areas of application The NANOCOLOR VARIO Mini really comes into its own wherever samples do not need to be transported to the laboratory first, but digestion must take place directly on site – for example, when a water supplier’s field team needs to check a limit value on site at the weekend and does not want to wait until Monday for the laboratory result: Mobile sampling and on-site digestion for field teams from water suppliers and environmental laboratories Water and wastewater monitoring away from fixed laboratory facilities Small laboratories and in-house laboratories with occasional, non-routine digestion requirements Supplementary equipment for laboratories that already own a larger benchtop unit and wish to be mobile as well Determination of COD, total nitrogen and total phosphorus in the field in accordance with DIN, EN, ISO and EPA methods Technical details Positions/boreholes6 × 16 mm outer diameter Temperature settings70 °C, 100 °C, 120 °C, 148 °C, 150 °C, 160 °C Temperature stability±1 °C (in accordance with DIN, EN, ISO, EPA) Dimensions (L×W×H)170 × 105 × 125 mm Weight (gross)1,450 g Power supply12 V, 5 A, 60 W DisplayBacklit graphic LCD, 128 × 64 pixels Operating conditions10–40 °C, max. 80% relative humidity (non-condensing) CertificationCE Contents 1x NANOCOLOR VARIO Mini thermoblock 1x power cable 1x Fold-away protective cover 1x User manual 1x Certificate Customised requirements & procurement service Do you need suitable NANOCOLOR cuvette tests, a T-Set for internal quality control or accessories for other thermoblock models?

Macherey-Nagel NANOCOLOR VARIO C2 single thermoblock, 12 positions, 919350
For day-to-day work in water and wastewater analysis, a piece of equipment is needed that the laboratory team can rely on day in, day out – one that is robust, large enough to handle the usual sample throughput, and easy to operate. The Macherey-Nagel NANOCOLOR VARIO C2 thermoblock is designed precisely for this purpose: as a single-block unit with 12 positions, it covers day-to-day operations in sewage treatment works, environmental and contract laboratories, without the added complexity of a dual-block unit or the limitations of a small portable device. Unlike the portable or particularly high-performance models in the range, it is deliberately designed to strike a balanced compromise between capacity, ease of use and purchase cost. 12 positions for day-to-day laboratory work The VARIO C2 accommodates up to 12 cuvette tests with an external diameter of 16 mm simultaneously and carries out the chemical digestion prior to photometric measurement. Six preset standard temperatures (70 °C, 100 °C, 120 °C, 148 °C, 150 °C, 160 °C) minimise operational errors in routine work, whilst six additional freely definable programme slots also cover individual or less frequently required digestion procedures without the need for a second instrument. The standard bore size of 16 mm is compatible with common NANOCOLOR cuvette tests, meaning that standard methods can be carried out directly without the need for special accessories. Precise temperature range, user-friendly operation The temperature range extends from 40 to 160 °C in 1 °C increments, with a stability of ±1 °C in accordance with DIN, EN, ISO and EPA methods. Compliance with these recognised test methods is particularly relevant for laboratories with a duty to provide evidence to regulatory authorities or clients, as it enables results to be documented in a traceable manner. Operation is via a backlit colour touchscreen with an icon-based menu in nine languages, including German, English and French, ensuring that even temporary staff or trainees can quickly find their way around. Space-saving for everyday laboratory use With external dimensions of 282 x 169 x 146 mm and a weight of 2,800 g (gross, including packaging), the VARIO C2 fits on any laboratory workstation without taking up valuable space at the fume cupboard or on the workbench. Its compact design also makes it easy to position next to a NANOCOLOR photometer, enabling a direct transition from digestion to measurement. Network-ready and capable of data logging RS232, USB-A and USB-B interfaces enable connection to PC systems and data exchange. Free software updates can be installed via the internet/PC or a USB stick. This simplifies both integration with existing laboratory software and the sharing of test reports as part of quality assurance. In combination with the optional NANOCOLOR T-Set (919917) or the USB version (919921), automatic calibration including a test certificate in accordance with DWA-A 704 is possible – an important component for internal quality assurance and for audits. Reliable in everyday laboratory use The VARIO C2 meets CE requirements and is designed for an ambient temperature range of 10 to 40 °C and a maximum relative humidity of 80 per cent (non-condensing), as required for continuous operation in everyday laboratory use. Position within the NANOCOLOR VARIO range In addition to the VARIO C2, Macherey-Nagel offers four further thermoblocks in the NANOCOLOR VARIO range: the portable VARIO Mini with 6 positions for use outside the laboratory; the VARIO C2 M with additional 22 mm bores for larger digestion vessels; the VARIO 4 with two independently controllable blocks and 24 positions for high throughput; and the VARIO HC with active cooling for shorter cycle times. For those who exclusively digest standard 16 mm cuvettes and find that 12 positions are sufficient for their day-to-day laboratory work, the VARIO C2 is the ideal central piece of equipment, without having to pay extra for specialised applications. Typical areas of application The VARIO C2 is the workhorse of the NANOCOLOR thermoblock range: designed for daily routine operation where a moderate number of samples need to be digested regularly, for example when a plant laboratory processes a fixed series of COD and nutrient samples every morning before the samples are analysed photometrically: Daily COD, total nitrogen and total phosphorus analysis in sewage treatment works and municipal wastewater treatment plants Routine digestion in in-house laboratories with their own wastewater monitoring Environmental and contract laboratories with a regular, predictable sample throughput Training and university laboratories as the central sample preparation unit for practical sessions Metal digestion and other photometric cuvette tests, in which up to 12 samples are digested in parallel Technical details Positions/boreholes12 × 16 mm outer diameter Temperature range40–160 °C, adjustable in 1 °C increments Preset temperatures70 °C, 100 °C, 120 °C, 148 °C, 150 °C, 160 °C (+ 6 freely definable slots) Temperature stability±1 °C (in accordance with DIN, EN, ISO, EPA) Dimensions (L×W×H)282 × 169 × 146 mm Weight (gross, including packaging)2,800 g Power supply110–230 V AC, 50/60 Hz, 150/300 W DisplayBacklit colour touchscreen, icon-based menu InterfacesRS232, USB-A, USB-B Operating conditions10–40 °C, max. 80% relative humidity (non-condensing) CertificationCE Contents 1x NANOCOLOR VARIO C2 thermoblock 1x mains cable 1x Fold-away protective cover 1x User manual 1x data cable 1x software DVD 1x certificate Customised requirements & procurement service Do you need suitable NANOCOLOR cuvette tests, a T-Set for automatic calibration or accessories for other thermoblock models?
