Buchner Filtration Flask with Side Arm, BORO 3.3
didn't see what you are looking for ?
Buchner Filtration Flask with Side Arm supplied by LabChoice Australia is purpose built for efficient vacuum filtration, solvent recovery and sample clarification across teaching, analytical and industrial laboratories. Commonly used with Buchner and Hirsch funnels, these heavy wall filter flasks provide a secure vacuum connection via the side arm, allowing rapid filtration of precipitates, activated carbon treatments, drying agent removal and routine sample clean up in chemistry, environmental and QC workflows.
Manufactured from premium BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, these flasks deliver excellent chemical resistance, strong thermal stability and reliable mechanical strength under routine laboratory handling. The thick walled body supports safer vacuum service by reducing stress concentration during pressure differential, while high clarity glass enables clear visual monitoring of filtration rate, foaming, bumping and filtrate level to minimise carryover and improve process control.
The integrated side arm is formed to provide a dependable interface with standard laboratory vacuum tubing, supporting a tight seal when used with correctly sized tubing and suitable clamps. In vacuum filtration assemblies, correct connectivity reduces leaks, improves filtration speed and helps maintain consistent suction. Where jointed neck options are supplied, ground glass tapers are manufactured in accordance with ISO 383 and ASTM E676 dimensional standards, supporting dependable compatibility with interchangeable glassware, adapters, vacuum manifolds and joint clips within modular setups.
All Buchner filtration flasks supplied by LabChoice Australia undergo ISO 9001 aligned quality control inspection. This typically includes wall thickness and form verification, side arm integrity checks, annealing and stress control review, surface quality inspection for defects that could compromise vacuum performance, and fit verification for stopper or jointed configurations where applicable. These controls support long term reliability, leak resistant operation and safe performance for laboratories requiring robust vacuum filtration glassware engineered from BORO 3.3 borosilicate glass.
