Instrumental and wet chemistry — balances, spectrophotometers, volumetric glassware and reference standards. Method documentation usually matters as much as the instrument itself.
High-quality volumetric pipette, or bulb pipette, quality grade AS (Class AS), with high accuracy. It has a single fixed graduation mark and measures one volume only, with a clear graduation line and a colour-code ring indicating the size. Bulb pipettes are more accurate than graduated pipettes. Manufactured and designed to ISO: 648.
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
Cuvette for spectrophotometers; Cuvette made of glass; Suitable for spectrophotometric measurement; A small clear rectangular vessel, sold in a range of materials, quality grades and sizes
Cuvette for spectrophotometers; Quartz cuvette for UV-Vis; Suitable for spectrophotometric measurement; A small clear rectangular vessel, sold in a range of materials, quality grades and sizes
Used to determine the specific gravity of liquids, or of solids in powder form or that can be ground to a powder; an instrument for finding the density of liquids. Most are made from borosilicate 3.3 glass with a glass stopper on top.
Low form weighing bottle with a clear lid, made of glass, used to hold solid or powdered chemicals for weighing on a balance, since it protects the balance from the chemicals and stops the substance from scattering. A weighing bottle is a piece of glassware used in chemistry laboratories and science classrooms.
Tall form weighing bottle with a clear lid, made of glass, used to hold solid or powdered chemicals for weighing on a balance, since it protects the balance from the chemicals and stops the substance from scattering. A weighing bottle is a piece of glassware used in chemistry laboratories and science classrooms. Size: 3 cm wide, 5 cm high, excluding the lid.
Made of high-quality rust-proof plated metal, highly durable with a service life of more than 10 years. Holds burettes on both sides (left and right), with plastic rollers that grip the burette firmly without breaking it. Suitable for burettes of many sizes, from 10 ml, 25 ml, 50 ml and 100 ml.
Auto-burette bulb, used to draw or push the solution held in the auto-burette bottle up into the burette barrel; Pushes the solution up in a single squeeze
