Filter Funnel with Perforated Disc includes laboratory filtration funnels designed for solid-liquid separation, sample preparation, precipitate collection, and routine laboratory filtration workflows. This category includes heavy duty porcelain Buchner funnels and BORO 3.3 glass filter funnels with perforated disc designs, giving laboratories practical options for filtration setups where durability, chemical resistance, and controlled drainage are required.
The BORO 3.3 glass filter funnel with perforated disc supports clear visibility during filtration and allows users to monitor liquid flow, residue build-up, and sample behaviour during laboratory work. The perforated disc provides a support surface for suitable filter media where required, helping maintain even drainage through the funnel body. BORO 3.3 borosilicate glass is widely used in laboratory glassware because it provides strong chemical resistance, thermal stability, low thermal expansion, and clear sample visibility.
The heavy duty porcelain Buchner funnel option provides a robust filtration choice for laboratories that require durable ceramic filtration equipment. Porcelain laboratory apparatus is commonly selected for routine filtration work where strength, chemical resistance, and repeated handling are important. Users should select the correct funnel type based on sample compatibility, filtration method, filter media requirement, vacuum setup, and laboratory workflow.
For best practice, inspect funnels before use, ensure compatible filter media is correctly seated, avoid sudden vacuum changes where vacuum filtration is used, and clean the funnel promptly after filtration to minimise residue build-up. Glass and porcelain filtration funnels should always be used with compatible receiving vessels, suitable seals or adapters, and appropriate laboratory supervision.
For material and quality reference, ISO 3585 specifies the properties of borosilicate glass 3.3 used for laboratory glassware, glass plant, pipeline, and fittings. ASTM E438 covers glasses used in laboratory apparatus, including Type I borosilicate glass categories. ISO 1775 is relevant to porcelain laboratory apparatus and covers material quality and test methods for porcelain laboratory equipment. These references should only be used as compliance claims where supported by manufacturer documentation and product certification.
For LabChoice Australia customers, Filter Funnel with Perforated Disc provides a practical category for chemistry laboratories, teaching laboratories, research facilities, environmental testing, sample preparation, precipitate collection, and routine filtration workflows requiring BORO 3.3 glass or heavy duty porcelain funnel options.
