Laboratory Flasks

Introduction to Laboratory Flasks

Laboratory flasks and bottles are specialized vessels for containing, preparing, measuring volumes, performing chemical reactions, or storing samples in testing laboratories. This category includes a variety of types such as Erlenmeyer flasks, volumetric flasks, desiccators, round-bottom flasks, pycnometers, wash bottles, vacuum filtration flasks, rotary evaporator flasks, and liquid nitrogen containers, comprehensively meeting analytical operation needs.

When choosing laboratory flasks and bottles, users should consider the operating purpose, volumetric accuracy requirements (such as Class A, Class AW, or Class B), and construction materials like heat-resistant borosilicate glass or plastics like PP, PE, PC, PFA. Furthermore, flask designs are diverse with narrow-neck, wide-neck, ground-joint, or screw-cap types. Hoa Viet currently distributes laboratory flask and bottle lines from manufacturers including Aptaca, Assistent, Duran, Haier, Hirschmann, Kimble-DWK, and Vitlab.

When should laboratory glass flasks be chosen versus plastic flasks?

Borosilicate glass flasks are suitable for applications requiring heating, handling strong organic solvents, or demanding clear visual observation. Plastic flasks made of PP, PE, or PFA are preferred when working with glass-corrosive solutions or when minimizing the risk of breakage during handling.

What is the difference between Class A and Class B volumetric flasks?

Class A volumetric flasks have tighter volume tolerance limits, suitable for quantitative analyses requiring high accuracy. Class B volumetric flasks have wider tolerances and are commonly used for routine chemical preparation or educational laboratory practicals.

When should amber or brown volumetric flasks be used?

Amber or brown glass volumetric flasks are specially designed for preparing and storing light-sensitive samples or solutions. This design helps block optical radiation from degrading or decomposing the chemicals inside.

Which brands of laboratory flasks does Hoa Viet currently supply?
