Laboy Glass Buchner Funnel Filter 2mL with 10mm Features

• DESIGN---This is a buchner funnel made of borosilicate glass, on top of the funnel-shaped part there is a cylinder with a sealed in fritted glass disc instead of filter paper.The liquid to be filtered is poured into the cylinder and drawn through the fritted glass disc.The porosity of the fritted glass disc have two options:the medium and course porosity.

• ADVANTAGE & FUNCTION----A buchner funnel using vacuum suction for filtration can proceed filtration more quickly than common simple filter funnel via the force of gravity.It is commonly used in organic chemistry to collect recrystallized compounds.This buchner funnel is usually used with a filtering funnel with side hose connection to a vacuum source,a rubber buchner flask adapter,and vacuum pump,vacuum tubing.It is not recommended for filtration where pressure would exceed 15psi.

• DIMENSIONS------The glass frit disc plate on top of the funnel with the pore diameter from 20 to 35micron .The outer diameter of the frit disc plate is 10mm.The capacity of the cylinder is 10mL.

• HEAVY WALL ---This buchner funnel is heavy-wall designed , made by hand-blowing according to ASTM E438 ,made of high-quality borosilicate glass and annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling,durable and reusable.

• 100% 90 DAY MONEY BACK GUARANTEE If you are not satisfied for any reason, simply return for a full refund, no questions asked. You have nothing to lose.Please also kindly undertand glassware is fragile, even if we pack them carefully,it may be broken during the shipment ,if you receive the items in broken status,don't hesitate to contact us ,we will arrange free replacement or full refund.

About Laboy Glass Buchner Funnel Filter 2mL With 10mm

A Büchner funnel is a piece of laboratory equipment used in filtration.Comparing to common filter funnel,the buchner funnel using vacuum suction can proceed filtration much more quickly. Buchner funnel is traditionally made of porcelain,but this one is made of borosilicate glass by hand-blowing,with sand-core glass fritted disc which can be immediately used especially when paper filters cannot withstand chemical attack of the filtration.It is used in organic chemistry labs to assist in collecting recrystallized compounds,usually used with buchner flask,buchner rings and rubber adapters. It is not recommended for filtration where pressure would exceed 15psi. Laboy glass funnels are heavy wall designed,made by hand-blowing to ensure uniform wall thickness, made of high-quality borosilicate glass and annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.
