Description
The Buchner Funnel, Sintered with Ground Joint for Vacuum Filtration, BORO 3.3 Glass, also known as a jointed sintered glass filter funnel, is laboratory filtration glassware used to separate suspended solids from liquids. Its integrated porous glass disc acts as a filtration medium, retaining particles according to the selected porosity grade while allowing liquid to pass through. It is suitable for laboratory sample preparation, precipitate collection, chemical processing and filtration procedures where a reusable glass filtration surface is preferred.
Manufactured from BORO 3.3 borosilicate glass, the funnel offers resistance to many laboratory chemicals and temperature changes encountered during routine filtration. Its glass construction is suitable for use with compatible aqueous solutions, chemical mixtures and organic solvents. The sintered disc is permanently integrated into the funnel, reducing the need for disposable filter media and providing a reusable filtration surface when properly cleaned and maintained.
The range includes five porosity grades, G-0 through G-4, allowing users to select the filtration characteristics required for their samples. G-0 provides the coarsest filtration, while G-4 provides the finest filtration within the available range. Intermediate grades G-1, G-2 and G-3 offer progressively finer particle retention. Selecting an appropriate grade helps balance particle retention and filtration flow, particularly when processing suspensions containing different particle sizes. Available in 35 mL, 80 mL, 200 mL, 500 mL and 1000 mL capacities, these sintered Buchner funnels accommodate different laboratory filtration requirements. Approximate sintered disc diameters range from 30 mm for the 35 mL funnel to 120 mm for the 1000 mL funnel. Smaller models are suitable for small-scale analytical procedures and sample preparation, while larger options can accommodate greater quantities of liquid and collected solids during filtration.
The ground glass joint connection allows the funnel to be fitted to a compatible receiving flask or filtration assembly with a matching joint size. When combined with suitable vacuum-rated glassware, vacuum tubing, a vacuum source and appropriate protection against liquid carryover, it can be used for vacuum-assisted filtration. The ground glass joint size should be confirmed before purchase to ensure compatibility with existing laboratory equipment.
Supplied by LabChoice Australia, this range of borosilicate glass sintered Buchner funnels is suitable for chemistry laboratories, universities, research institutions, quality control facilities and industrial testing applications. With 25 combinations of capacity and porosity available, laboratories can choose a funnel suited to their sample volume, particle retention requirements and existing vacuum filtration setup. Each funnel is supplied individually.
