Graduated Glass Beaker with Handle

Graduated beakers with handles are made of borosilicate glass 3.3 and designed to offer a versatile and safe solution for laboratory operations requiring precision, resistance, and ease of handling.

Produced in the Czech Republic in accordance with DIN 12331 and ISO 3819 standards, they guarantee quality, uniformity, and reliability in scientific applications. Their design incorporates a graduated scale that allows a quick estimation of volumes, as well as an integrated handle that improves ergonomics and facilitates handling, especially in heating or transfer processes.

Borosilicate glass 3.3 provides exceptional chemical resistance against water, saline solutions, acids, alkalis, and most common reagents. Its main limitation is against hydrofluoric acid and in conditions of prolonged exposure to concentrated bases at high temperatures. Thanks to its low coefficient of thermal expansion (3.3), it offers excellent resistance to thermal shock, making it suitable for processes with abrupt temperature variations.

These containers support autoclave sterilization, allowing multiple use cycles without compromising their physical or chemical properties. Their robust structure makes them suitable for demanding working environments where aggressive substances are handled or intense thermal conditions are required.

The material has a composition mainly based on silica (80.00 %) and boron oxide (12.50 %), along with other components that reinforce its stability. Additionally, it complies with high hydrolytic resistance classifications (Class 1 according to DIN 12111 and ISO 719), ensuring durability and stable behavior in contact with liquids.

These beakers are an essential element in analysis, research, education, and industry laboratories, being suitable for mixing, heating, dissolution, and liquid handling operations.

An ergonomic, resistant, and precise solution for daily laboratory work.
