Laboy Glass High-Quality Separatory Funnel with PTFE Stopcock and Standard Taper Joints

Design: This borosilicate glass buchner funnel features a cylinder with a sealed, perforated glass disc for filtration using filter paper. This design solves the contamination and blindness problems associated with ceramic buchner funnels.
Advantage & Function: The vacuum suction used in this buchner funnel allows for faster filtration than simple gravity filtration. It is commonly used in organic chemistry to collect recrystallized compounds. This funnel is typically used with a filtering funnel, rubber buchner flask adapter, and vacuum pump, and is not recommended for filtration where pressure exceeds 15psi.
Dimensions: The outer diameter of the glass disc plate is 90mm, with a height of 90mm above the plate and a total height of 230mm. The cylinder has a capacity of 500mL.
Heavy Wall: This buchner funnel is heavy-wall designed, hand-blown according to ASTM E438, and made of high-quality borosilicate glass. It can be heated directly in an open flame and is durable and reusable, able to withstand typical laboratory thermal variations in chemistry processes like heating and cooling.
Safety Reminder: Avoid applying pressure above 1 atmosphere and handle with care to prevent breakage.
