Special Price $26.18 Regular Price $40.52
- DESIGN---This is a buchner funnel made of borosilicate glass, on top of the funnel-shaped part there is a cylinder with a fritted glass disc instead of filter paper.The liquid to be filtered is poured into the cylinder and drawn through the fritted glass disc by vacuum suction.With a jointed vacuum take off adapter at bottom, it has a lower standard taper inner joint and serrated hose connection to a vacuum source.
- 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 with vacuum take off is usually used with a heavy wall Erlenmeyer flask.
- DIMENSIONS------The glass frit disc plate on top of the funnel with the pore diameter from 10 to 20 micron .The outer diameter of the frit disc plate is 20mm.With 19/22 standard taper inner joint at the/ lower part and a side glass hose connection with 10mm O.D.at the largest serration.The capacity of the cylinder is 15mL.
- 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.
