Instrumental and wet chemistry — balances, spectrophotometers, volumetric glassware and reference standards. Method documentation usually matters as much as the instrument itself. Borosilicate glassware from Duran and Pyrex, including beakers, Erlenmeyer and volumetric flasks (Class A), measuring cylinders, round-bottom flasks and laboratory bottles. We supply universities, schools and labs across Thailand, and quotations are free.
Burette glass is an instrument used for titration, in the form of an amber glass tube with volume graduations and an open-close valve to control the release of the solution inside into the reaction, so the volume of reagent used in an experiment can be measured precisely.

Glass separating funnel with a PTFE stopcock (Separatory Funnel). A separating funnel is used for solvent extraction, or Liquid-Liquid Extraction, to separate two or more mixed liquids that form layers because of differing density or polarity, such as water and oil or water and organic solvents. The item is made of glass.
A sample vial, laboratory glassware used to store samples and solutions and for HPLC, GC and ICP work, made from high-quality Borosilicate. The commonly used accessory is red PTFE/White Silicone septa; caps come in two types, solid and with a hole.
A clear glass bottle for holding solutions. Sample vials are laboratory glassware used to store samples and solutions and for HPLC, GC and ICP work, made from high-quality Borosilicate. The commonly used accessory is red PTFE/White Silicone septa; caps come in two types, solid and with a hole.
Volumetric flask with stopper; the flask is made of glass and the stopper of plastic, with a long neck carrying a single volume graduation mark. Used for measuring where high accuracy is required, commonly for preparing solutions, Class A.
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.
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.
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
