DESIGN----The pressure equalizing funnel is a special type of dropping funnel .Comparing to the ordinary cylindrical dropping funnel and pear-shaped separatory dropping funnel,it is designed with an additional glass tube at side from the top of cylindrical body to the tube between the stopcock and lower male joint.The funnel features a graduated cylindrical tube as main body,with standard joints at top and bottom,a 0-4mm high vacuum valve above the lower joint.
ADVANTAGE---A pressure equalizing funnel is used to add exact amounts of liquid to the receiving flask slowly and smoothly.With the side narrow-bore tube,the liquid form the funnel drops smooth without having to remove the glass joint stopper.In a reflux reaction,the funnel will be attached to one neck of the receiving flask,while the reflux condenser will be placed on the other neck.It is also ideal to handle air-sensitive reagents in a sealed,inert-gas environment.
DIMENSIONS------This graduated addition funnel has a capacity of 60mL,with 14/20 top and bottom joints, with a 0-4mm high vacuum valve above the lower male joint.
HEAVY WALL ---This dropping funnel is heavy-wall designed , made by hand-blowing according to ASTM E438 ,made of high-quality borosilicate glass and annealed at 807 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.
