Glass beakers

Introduction to Glass beakers

A glass beaker is a fundamental laboratory tool used for holding, mixing, dissolving, heating, and estimating the volume of liquids in the laboratory. Manufactured from borosilicate glass 3.3 with uniform wall and bottom thickness, it provides excellent thermal resistance, chemical resistance, and thermal shock resistance.

When purchasing, users can select between low-form or tall-form beakers, with or without spouts, and graduated or non-graduated designs based on operational needs. The capacity ranges from 5 ml, 10 ml, 50 ml, 100 ml, 600 ml up to 2000 ml, complying with standards such as DIN EN ISO 3819 or ASTM E960 Type I. Hoa Viet currently distributes genuine glass beakers from brands including Duran (Germany), Assistent (Germany), and Kimble-DWK (USA).

How do low-form and tall-form glass beakers differ?

Low-form beakers have a wider base diameter, providing good stability and convenience when mixing or heating solutions. Tall-form beakers feature vertical walls and a greater height, helping to minimize chemical splashing during vigorous reactions or stirring.

Are the graduation marks on glass beakers used for accurate volume measurement?

Graduation marks on glass beakers are intended only for rough volume estimation during preparation. If an analytical procedure requires high volumetric accuracy, laboratory personnel must use graduated cylinders, pipettes, or volumetric flasks.

Which technical standards do laboratory glass beakers comply with?

Depending on origin and brand, glass beakers may comply with DIN EN ISO 3819 or ASTM E960 Type I standards. These standards specify requirements for borosilicate glass 3.3 material, geometric dimensions, and uniform wall thickness.
