Description
Buchner Funnels Sintered for Vacuum Filtration, BORO 3.3 are designed for fast, dependable vacuum filtration where consistent particle retention and repeatable flow are essential. The integrated sintered glass frit provides a uniform porous filtration surface, eliminating the need for filter paper and supporting cleaner, more consistent separations in sample preparation, precipitate collection, solvent clarification, catalyst recovery, and general solid–liquid separation workflows. This makes sintered Buchner funnels a practical choice for laboratories seeking reduced consumable use and more reproducible filtration performance.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, these funnels offer excellent thermal stability, low thermal expansion, and strong chemical resistance to many common laboratory reagents and solvents. BORO 3.3 glass performance aligns with recognised borosilicate standards such as ISO 3585 and ASTM E438 Type I, supporting dependable durability under routine laboratory handling and the pressure differentials associated with vacuum filtration. Smooth glass surfaces support efficient cleaning, while consistent wall thickness improves robustness for frequent use in teaching, research, and industrial QC settings.
The sintered disc delivers stable flow under vacuum and retains solids according to the selected porosity grade, supporting reliable filtration for fine particulates and precipitates. For best practice, match frit porosity to your particle size, avoid sudden vacuum surges, and clean the frit promptly after use to prevent clogging. Always inspect glassware for chips or star cracks before vacuum use, and seat the funnel securely on a compatible filter flask using the correct rubber cone adapter or jointed connection.
Supplied by LabChoice Australia, these BORO 3.3 sintered Buchner funnels are widely used across Australian universities, research institutes, environmental laboratories, and industrial quality control environments where dependable vacuum filtration and durable borosilicate construction are required.
