Meditrade Nitrile Black Examination Gloves, black (100 pcs.), 1284X
Meditrade Nitril Black is a powder-free, latex-free nitrile examination glove that combines high levels of protection with a striking black appearance. It is dual-certified as a Class I medical device and as Category III personal protective equipment. Black colour for tattooing, beauty treatments, catering and contrast detection The black colour is popular wherever stains from ink, paint or food need to be concealed, or where a uniform, professional appearance is desired. In tattoo and beauty salons, black has now almost become the standard; it looks professional and does not immediately reveal colour residues from ink or pigments. In the catering industry and at events, the uniform black appearance ensures staff look well-groomed. In laboratories and in the medical sector, black offers a practical additional benefit: light-coloured powders, tablets or crystals stand out clearly against the dark glove, making it easier to spot spills or contamination – a contrast that a natural-coloured glove does not provide. Latex-free The glove is completely latex-free, providing a safe alternative for staff with a diagnosed Type 1 latex allergy, regardless of the area of application. Certified to EN 455 and PPE Category III The Nitril Black complies with EN 455 for examination gloves and is classified as Category III personal protective equipment (PPE), the highest PPE category for complex risks. It is also suitable for contact with food.

Meditrade NextGen Nitrile Examination Gloves, blue, 100 pcs., sizes XS–XXL, 1283X
In day-to-day laboratory work, a nitrile glove must do two things at once: provide reliable protection whilst being so unobtrusive that you forget you’re wearing it whilst working. The Meditrade Nitrile NextGen is designed precisely for this purpose. It is blue, powder-free, latex-free and holds dual certification: as a Class I medical device and as Category III personal protective equipment. This means that a single pack covers what would otherwise require two different types of gloves in the cupboard. Blue nitrile gloves: why the colour matters In laboratory and medical settings, blue is the established signal colour for disposable gloves. It stands out clearly against most work materials, which has two practical advantages. Firstly, a tear or hole is spotted more quickly because of the high contrast with the skin. Secondly, a torn piece of glove is easier to spot in a production process or in a sample than one that is a natural colour. In food processing, this is precisely why blue gloves have been the standard there for years: the colour is virtually never found naturally in food. Thickness, tear resistance and grip The glove is deliberately designed to be thin so that tactile sensitivity is maintained. The thickness is 0.07 mm on the palm, 0.10 mm on the fingertips and 0.07 mm on the back of the hand, in each case with a tolerance of 0.02 mm. The slightly greater thickness on the fingers is no coincidence; this is the area subject to the greatest mechanical stress. Despite the thin material, the median tear strength is at least 6.0 N, both when new and after artificial ageing. This is the more relevant of the two values, as gloves are rarely found on the shelf straight from production. The surface is micro-textured. This ensures a good grip when vessels, pipettes or instruments are damp, without the need to grip any tighter than necessary. The rolled cuff stabilises the glove whilst putting it on and prevents it from rolling down whilst working. With a length of at least 240 mm, it extends securely over the wrist. Latex-free, powder-free, protein-free The Nitrile NextGen is manufactured without natural rubber latex and is therefore suitable for people with a diagnosed type 1 latex allergy. As it is also powder-free, it does not contain maize starch dust, which acts as an allergen carrier in powdered gloves and is a source of particles that can cause disruption in cleanrooms or during sensitive analyses. The glove is also free from mercaptobenzothiazoles and thiurams, two groups of accelerators that are frequently responsible for type 4 contact allergies. However, it does contain dithiocarbamates, which is why it should not be used by anyone with a known hypersensitivity to this group of substances. Dual certification: medical device and PPE Category III As an examination glove, the Nitrile NextGen complies with the EN 455-1 to EN 455-4 series and is classified as a Class I medical device under Regulation (EU) 2017/745. At the same time, it is Category III personal protective equipment (PPE) under Regulation (EU) 2016/425, i.e. the highest category intended to protect against irreversible damage to health. This is demonstrated by testing in accordance with EN 374-1, -2, -4 and -5, as well as EN 16523 for permeation and ASTM F 1671 for the penetration of blood-borne pathogens. The general requirements for protective gloves set out in EN 21420:2020 are also met. The gloves are tested for freedom from holes with an AQL of 1.5. They are manufactured under a quality management system in accordance with EN ISO 13485:2016. The gloves are expressly suitable for contact with food. Typical areas of use Laboratory: sample preparation, handling reagents and disinfectants, work at the workbench, cleaning glassware Medicine and care: examinations, taking samples, changing dressings, patient contact Food processing: Portioning, packaging, order picking, work relating to production hygiene Industry and cleaning: handling cleaning and disinfectant chemicals, assembly and testing work requiring a delicate touch A typical real-world scenario: In a routine laboratory, samples are prepared in the morning, analytical work is carried out at midday, and disinfection takes place in the afternoon. Anyone who has to keep three different types of gloves on hand for this has three stocks to manage and three potential sources of error when reaching into the box. A glove that complies with both EN 455 and PPE Category III, and is also food-safe, reduces this to a single item. Storage and shelf life Store in a cool, dry place and protect from direct sunlight. The shelf life is 3 or 5 years depending on the batch; the exact date is stated on the packaging. The glove is non-sterile and intended for single use only; reuse is not permitted, even after cleaning, as changes in the material cannot be reliably detected.

Meditrade Gentle Skin Sensitive Latex Gloves, natural colour, powder-free, 100 pieces, size L, 1221RLT
Meditrade Gentle Skin Sensitive is a low-protein examination glove made from natural latex, designed for situations where tactile sensitivity and a snug fit are particularly important – such as for tasks requiring fine motor skills in laboratories and the care sector. Natural latex offers high elasticity with low mechanical tension, allowing the glove to fit snugly without causing fatigue even during prolonged wear. Low-protein thanks to a sophisticated processing method Natural latex naturally contains water-soluble proteins which can trigger allergic reactions in some people. The Sensitive range is therefore treated using a multi-stage washing process (leaching), which largely removes proteins and residues from the manufacturing process – the protein content is less than 30 µg/g. The inside is also chlorinated, making the gloves easy to put on without powder. Non-slip and tear-resistant The micro-textured surface ensures a secure grip, both when dry and in contact with liquids such as saline solution or blood. With a tear strength of at least 6.0 N (pre-ageing, in accordance with EN 455-2) and an elongation of at least 650 per cent, the glove is designed for frequent donning and doffing in everyday clinical and laboratory practice; the rolled cuff further reinforces the cuff edge to prevent it from unrolling. Standards and scope of use The glove complies with EN 455 (Parts 1–4) for single-use medical gloves; it is certified as a Class I medical device in accordance with EU Regulation 2017/745 and as Category III PPE in accordance with EU Regulation 2016/425, and is chemical-resistant in accordance with EN ISO 374-1 (Type C) and offers protection against viruses in accordance with EN ISO 374-5. With an AQL of 1.5, barrier integrity is ensured to a high standard. Furthermore, they are suitable for food contact in accordance with BfR Recommendation XXI – relevant, for example, for sample preparation in food analysis. As they are made of natural latex, the gloves may swell on contact with non-polar solvents (e.g. oils, fats) and should not be used for this purpose – nitrile gloves are the more suitable choice in such cases.

Meditrade Gentle Skin Grip, latex examination gloves, powder-free, 100 pieces – M, 1221GRIP-M
Polymer physics and elastic kinematics In clinical and chemical-analytical laboratory practice, uncompromising mechanical barrier protection whilst maintaining tactile sensitivity is crucial. The Meditrade Gentle Skin Grip is made from high-purity natural rubber latex (polyisoprene). The macromolecular matrix of this biogenic polymer offers mechanical tear resistance and elasticity that synthetic elastomers can scarcely match physically. Unlike nitrile or vinyl, the highly cross-linked isoprene chains return almost entirely to their original structure following severe mechanical stretching or torsional stress (memory effect). This extreme restorative force ensures that the glove fits snugly against the skin, thereby eliminating dead spaces and drastically reducing occupational muscle fatigue during repetitive pipetting tasks. Tribological adhesion and tactile metrology Handling smooth, wet glass flasks or microscopically small analytical vials requires optimal rheological interface conditions. To prevent uncontrolled slipping, Gentle Skin Grip gloves feature a fully textured (micro-roughened) surface structure. This specific modification significantly increases the coefficient of friction at the polymer interface. It generates maximum micromechanical adhesion (grip) between the glove and the instrument, without dampening the transmission of haptic impulses to the mechanoreceptors in the fingertips. Prevention of immunological contamination and aerosol blockage Natural rubber latex contains water-soluble proteins which can trigger immunological reactions in sensitised users. The complete absence of powder on the inner lining of the Gentle Skin Grip acts as an essential preventive barrier. The powder-free design blocks the fluid-dynamic formation of aerosols from carrier particles when putting on and taking off the gloves. This prevents the airborne spread of rubber proteins and minimises the risk of respiratory sensitisation; however, it strictly excludes the system for users with an already established Type I latex allergy. Furthermore, the powder-free surface effectively prevents metrological cross-contamination caused by stray talc particles in sensitive molecular biological (PCR) or spectroscopic trace analysis. Technical details Product type: Disposable examination and protective gloves (variations available for all sizes) Material: Natural rubber latex (polyisoprene) Tribology: Micro-textured surface across the entire surface for maximum tactile adhesion Kinematics: Extreme elastic recovery and macromolecular tear resistance Occupational safety: Powder-free to eliminate particle aerosols and cross-contamination Immunological limitations: Contains biogenic rubber proteins (contraindicated in cases of diagnosed Type I latex allergy) Design: Suitable for use on either hand (ambidextrous), with a mechanically rolled cuff Packaging unit (PU): 1 dispenser box = 100 pieces Contents 1 x Meditrade Gentle Skin Grip dispenser box in the selected size (contents: 100 pieces) (Important note: This is a non-sterile, single-use consumable which must be disposed of properly following any chemical or biological contamination!) Individual requirements & accessories Choosing the exact glove size (XS to XL) is not only a matter of ergonomics but is also essential from an occupational health perspective: an elastomer that is too tight is under constant tensile stress and is prone to rupture, whilst a glove that is too large compromises tactile precision and creates pathways for solvents to enter the cuff. To efficiently ensure logistical availability in high-throughput laboratories, we recommend purchasing in sealed bulk cardboard packs (10 boxes of 100 pieces each).

Unicare Black Latex, Latex gloves, Black, Powder-free, 100 pieces - S, GS2902
Unicare Black Latex is a powder-free latex examination glove in black, which is also certified as a chemical-protective glove in accordance with EN 374 (Type B). It therefore offers documented protection against viruses, fungi and bacteria and is suitable for tasks requiring more than just basic medical protection. Documented chemical protection Unlike a standard examination glove, the Black Latex has been tested in accordance with EN ISO 374-1 against a range of specific chemicals, with documented permeation values for caustic soda, sulphuric acid, nitric acid, hydrogen peroxide and formaldehyde. This makes it a better choice than a standard examination glove wherever more aggressive chemicals are handled in the laboratory or during cleaning, not just when dealing with water and mild disinfectants. Black colour for contrast and visibility The black colour stands out clearly against light-coloured powders, tablets or substances, making spilled material in the laboratory easier to spot than with a natural-coloured glove. At the same time, black is a popular, professional-looking alternative to the usual light-coloured disposable gloves in sectors such as cosmetics, tattooing and catering. Please note: latex allergy The glove is made from natural rubber latex; it is not suitable for users with a diagnosed latex allergy – in such cases, we recommend a nitrile alternative from our range.

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 VISOCOLOR Fish Analysis Kit, 933101
The VISOCOLOR Fish test kit has been specially developed for the analysis of fishing waters. It combines reagents and accessories for the six most important water parameters in a single kit: ammonium, nitrate, nitrite, phosphate, pH and total hardness. Six key parameters for water quality Anyone wishing to assess fishing waters cannot afford to ignore these six parameters: ammonium, nitrate and nitrite indicate nitrogen loading and thus, indirectly, the condition of the fish population; phosphate indicates nutrient inputs and algal growth; whilst pH and total hardness provide the basic data for almost any further hydrological assessment. With a single kit, the most important parameters for a fisheries water assessment can be covered directly on site, without having to put together several individual tests. Use in fish farming, club waters and water monitoring Whether monitoring an aquaculture pond, carrying out a routine check by an angling or fishing club on its own waters, or taking a random sample as part of official water monitoring: the kit provides the key parameters needed to identify pollution issues at an early stage, before they endanger fish stocks. As all the tests can be carried out without an additional photometer, the kit can be used directly at the water body – without a power supply or sensitive additional equipment. Ready for immediate on-site use The kit includes a case, test kits, accessories and instructions – results are interpreted purely visually by colour comparison. The reagents have a shelf life of 1.5 years from the date of manufacture and should be stored at 15–25 °C to ensure that results remain reliable throughout their entire service life.

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.

Customised requirements & accessories To ensure the optimal integration of Macherey-Nagel round filters into your daily laboratory routine, we offer a comprehensive range of complementary accessories. For standard filtration, our portfolio includes robust glass funnels, polypropylene funnels, as well as suitable laboratory stands and funnel holders. For contamination-free and gentle handling of the wet circular filter discs, we recommend the use of flat-tipped filter tweezers made from high-alloy, corrosion-resistant stainless steel. For subsequent drying or storage processes, we also offer chemically inert Petri dishes, watch glasses and desiccators. Please make use of our technical procurement service to design your filtration workstations to suit your specific requirements.
Macherey-Nagel MN 615 circular filter, high quality, medium-speed (Ø 25 – 500 mm)
The all-rounder for the laboratory: Macherey-Nagel MN 615 round filters Macherey-Nagel MN 615 round filters are an indispensable part of the basic equipment for chemical analysis and industrial quality assurance. 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. As a rule of thumb: when inserted, the filter should not protrude beyond the rim of the funnel, but should end approximately 1–2 cm below the rim. Technical data Type: MN 615 Type: High-quality filter paper, round filter Filtration speed: 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 Packaging unit: 100 pieces per pack Contents 1 x pack of 100 Macherey-Nagel round filters (type MN 615) (The diameter corresponds to the variant you selected above.) Individual requirements & accessories Filter paper is only as good as the accessories used with it. To ensure your filtration process runs smoothly, you’ll need the right funnel. Suitable funnels: Whether made of glass or robust plastic (PP/TPX) – ensure that the filter diameter you have chosen matches the funnel size (the filter should end approx. 1–2 cm below the rim). Other pleat configurations: Do you require faster filtration whilst maintaining the same pore size? We also stock this type as a pleated filter (increased surface area). Quantitative analyses: If you need to ash the residue (gravimetry), you will require ash-free filters (e.g. MN 640). Can’t find the right size, or do you need large quantities for industrial applications? We can source any speciality filter for you. Please contact our procurement service.

Macherey-Nagel VISOCOLOR School Analysis Kit, 933100
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. This significantly lowers the barrier to entry for schools and other educational institutions with limited equipment and enables several groups to work simultaneously – each group with its own test kit, without a single measuring device becoming a bottleneck. Cost-effective refills Once the supplies have run out, there’s no need to buy a whole new kit: an affordable refill pack is available if required.
