Vacuum Flask

The Erlenmeyer-shaped vacuum flask, also called a Büchner flask, has several distinctive features:

Shape and Structure:
Wide base and conical body, topped with a cylindrical neck.
A side arm with an olive (or glass connector) for connection to a vacuum source, such as a water pump or vacuum pump.
Thick walls to withstand the negative pressure generated during vacuum filtration. Includes a “cleated” base for greater stability and minimized abrasion.

Material:
Made of borosilicate glass (such as DURAN® or PYREX® glass), offering good chemical and thermal resistance.

Functionality:
Designed specifically for vacuum filtration, allowing rapid separation of solid and liquid phases.
Can be used for mixing, cooling, incubation, filtration, and storage in the laboratory.
Autoclavable for sterilization if made of a suitable material.

Compliance:
Complies with international standards such as ISO 6556 or DIN 12476.
