Glassco Filtration Flask with Glass Side-Arm Connector
The Glassco filtration flask with glass connector is a borosilicate 3.3 glass vacuum flask specifically designed for use in vacuum filtration assemblies. The side-arm glass connector enables direct connection to a vacuum pump, water aspirator, or house vacuum line, creating the reduced pressure conditions required for efficient Buchner funnel filtration, membrane filtration, and other vacuum-assisted laboratory filtration procedures.
Manufactured from borosilicate 3.3 glass to ISO standards, these filtration flasks combine the chemical resistance and thermal stability required for routine filtration workflows with the structural integrity needed for safe operation under vacuum conditions. Available in capacities from 100mL to 2000mL, supplied from Glassco’s European warehouse in the Netherlands for fast delivery across Ireland.
Key Features
Glass Side-Arm Connector
The integrated glass side-arm connector enables connection to vacuum sources using standard laboratory vacuum tubing — providing a reliable and chemically resistant vacuum connection point. The all-glass construction of the connector avoids the permeability and degradation limitations of plastic or rubber side-arm fittings in aggressive solvent filtration applications.
Vacuum-Compatible Construction
The thick-walled borosilicate 3.3 glass construction provides the mechanical strength required for safe operation under vacuum, minimising the risk of flask implosion during routine filtration procedures.
ISO Compliant — Borosilicate 3.3 Glass
Manufactured from borosilicate 3.3 glass to ISO standards, providing excellent chemical resistance for filtration of aqueous, acidic, basic, and organic solvent-containing solutions across routine laboratory filtration workflows.
White Printing
Durable white capacity markings for clear filtrate volume monitoring during filtration procedures.
