Instrumental and wet chemistry — balances, spectrophotometers, volumetric glassware and reference standards. Method documentation usually matters as much as the instrument itself. Lab reagents, culture media and everyday consumables: Merck and RCI-Labscan solvents and analytical-grade chemicals, Merck and Difco media, pH buffers and conductivity standards, chlorine and hardness test kits, pipette tips, microtubes, Petri dishes and Whatman filter paper. Send the list with grade and pack size, and we will quote it free on the same quotation as your instruments and glassware.

Methanol, also known as methyl alcohol, is a non-potable alcohol widely used as an industrial solvent, for example for cleaning plastics, in adhesives for plywood and as a component of biodiesel. It is also a main raw material for producing formaldehyde, a solvent used in paints and polishes.
A membrane filter is a polymer film with a specific rated pore size; the membrane retains particles and micro-organisms larger than the pores, acting as a physical barrier and capturing them on the membrane surface. Labfil membranes are available in a range of polymers, pore sizes, diameters and surface types.
Pack size 1 L. A standard solution for calibrating pH electrodes so that they can measure pH accurately in other solutions, certified to NIST standards. This chemical is for laboratory use only and is supplied with a safety data sheet.
Pack size 1 L. Buffer solutions are essential for maintaining the calibration of pH meters so that measurements are correct, precise and reliable, giving good results to CRM (Certified Reference Material) standard when analysing products; also certified to ISO Guide 34 and ISO/IEC 17025.
Potassium dihydrogen phosphate (also called potassium phosphate monobasic) is an inorganic salt used in solution in fertiliser production, as an additive and as a buffering agent, and is soluble in water.
Pack size 1 kg. A corrosive, highly hygroscopic alkali in the form of white crystals or flakes. Widely used in battery manufacturing as an alkaline cell material; soluble in water, used to make liquid soap, and also soluble in alcohol.
Premium grade with purity up to 99%, suitable for high-precision laboratory analysis, as well as laboratory analytical work, chemical synthesis and chromatography.
Pack size 1 kg. Premium-grade sodium chloride (salt) with purity up to 99.99%, suitable for high-precision laboratory analysis. It meets ACS/ISO standards and the European Pharmacopoeia standard for analytical reagents (Reag. Ph Eur), making it usable in every industry.
Sodium chloride, commonly known as table salt or halite, is a chemical compound responsible for the salinity of the oceans and of the extracellular fluid of multicellular organisms. It is the main component of edible salt and is widely used in the food industry as a seasoning and for food preservation.
Pack size 1 kg. Sodium hydroxide, also known as caustic soda, chemical formula NaOH, is a strong, corrosive base used in many industries such as the chemical, food, pulp and paper, and soap and detergent industries.
Aluminium-backed plate for thin-layer chromatography, 20 x 20 cm. Suitable for many applications such as preliminary separations, herbal medicines, substances in food and beverages, and semi-quantitative testing of drug synthesis.
Cellulose glass plates, 20 x 20 cm, suitable for highly efficient separation compared with thin-layer chromatography sheets (TLC Aluminium Sheet); 25 plates per box
A premium-grade chemical with purity up to 99.5%, suitable for high-precision laboratory analysis, as well as laboratory analytical work, chemical synthesis and chromatography.
Buchner funnel in a strong, durable material that does not break easily, resists chemical corrosion and withstands high heat. Used for vacuum filtration of mixtures with a liquid component; commonly used with crystalline precipitates and not suited to fine or gelatinous precipitates, because suction from the pump clogs the filter paper and prevents liquid from passing through it into the holes of the funnel.
Evaporating dish for research work, evaporating the solvent away from a solid mixed into it; the solvent used is most often water; Resistant to acids, alkalis and various chemicals
