Addition Pressure Equalizing Funnel/Lines Graduated 125ml W/ 14/20 Joint &2mm Ptfe Stopcock
Special Price $60.66 Regular Price $93.87
- 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 PTFE stopcock 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 125mL,with 14/20 top and bottom joints, with a 2mm PTFE stopcock 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 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.
A dropping funnel usually features a graduated cylindrical tube or pear-shaped bulb as the main body.With female ground glass joint at top which can be stopped by a penny head joint stopper.The lower part of the funnel has a glass or PTFE stopcock to control the flow and a standard taper male joint.The dripping tube extends a bit below the lower joint. Separatory funnel with lower joint can be used as a dropping funnel.
This pressure equalizing funnel is a special type of dropping funnel which are used to add liquid slowing.Comparing to the common cylindrical dropping funnel,it features an additional glass tube that begins from top of the cylindrical body, continues to the lower tube, in the space below the stopcock and above the male ground glass joint.With the tube,the liquid from the funnel drops smooth without having to remove the stopper.The pressure equalizing funnel is perfect to add exact amounts of liquid to the receiving flask.
With standard taper glass outer joint at Top and inner joint at bottom, with a glass stopcock upper on the bottom glass joint.
Laboy glass flasks 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.
