Description
The Erlenmeyer Conical Filtering Flask with Glass Connector from Osmosis Scientific is engineered for efficient vacuum filtration, aspiration, and separation tasks commonly encountered in analytical, biochemical, and quality control laboratories. Manufactured from premium Borosilicate Glass 3.3, this flask exhibits superior thermal shock resistance and robust chemical durability, making it well-suited for repeated use under demanding lab conditions.
Featuring a conical Erlenmeyer body with a glass side connector, this filtering flask allows secure vacuum line or hose attachment for use with Büchner funnels and other filtration accessories. The heavy wall construction is designed to withstand reduced pressures safely, making it ideal for vacuum filtration of suspensions, particulate separations, and rapid phase clarifications.
Available in a wide range of capacities from 50 ml up to 5000 ml, this filtration flask accommodates both small-scale and larger volume filtration applications. Its flat base supports stable bench placement, and the borosilicate glass composition ensures excellent resistance to aggressive reagents and temperature variation.
Ideal for use in pharmaceutical QC, research laboratories, microbiology labs, environmental testing, and industrial workflows, this conical filtering flask blends durability, vacuum performance, and versatile capacities to support daily laboratory filtration needs.

Frequently Asked Questions (FAQs)
It is used for vacuum filtration, mixing, and collecting filtrates in laboratory procedures, especially when coupled with a Büchner funnel or filter holder to separate solids from liquids under reduced pressure.
The integral side arm (tubulation) connects to a vacuum source via flexible tubing, allowing rapid evacuation of air to support vacuum-driven filtration.
Regular Erlenmeyer flasks are not designed for vacuum stress and lack the side arm; attempting vacuum filtration in them risks flask breakage and safety hazards.
They are typically manufactured from borosilicate 3.3 glass, offering thermal shock resistance, chemical durability, and strength under vacuum conditions.
