Description
Buchner Funnel Sintered with Side Arm, BORO 3.3 is designed for efficient vacuum filtration where fast separation, controlled drainage, and reduced consumable use are essential. The integrated sintered glass frit provides a uniform porous filtration surface, removing the need for filter paper and supporting cleaner, more consistent particle retention during precipitate collection, catalyst recovery, solvent clarification, and sample preparation. The built-in side arm enables direct connection to vacuum tubing, supporting stable suction and improving filtration speed and repeatability in busy laboratory workflows.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, this funnel offers excellent thermal stability, low thermal expansion, and strong chemical resistance to many common laboratory solvents and reagents. 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 work. Smooth internal glass surfaces help minimise residue retention and support thorough cleaning, while consistent wall thickness improves robustness for frequent use.
The sintered disc delivers reliable flow under vacuum and retains solids according to the selected porosity grade, making it suitable for filtration of fine particulates and challenging precipitates. For best practice, match frit porosity to 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 applying vacuum, and secure tubing with a clamp to reduce slip risk.
Supplied by LabChoice Australia, this BORO 3.3 sintered Buchner funnel with side arm is widely used across Australian universities, research institutes, environmental laboratories, and industrial quality control facilities where robust borosilicate construction and dependable vacuum filtration performance are required.
