ADAMAS-BETAADAMAS-BETA Glass Constant Pressure Graduated Addition Funnel with Double PTFE Stopcocks,Equalizing Dropping Funnel Chemistry Lab Glassware (B: 500ml,24/40)
Main highlights- Warranty - Glassware is fragile, if received damaged, please don't hesitate to contact us,we will solve it until satisfied.
- Specification - various specifications are availiable,25ml,60ml,125ml,250ml,500ml.Glass stopcock and double PTFE stopcock are for your choice.
- Premium Material - Made of high-quality glass, durable and reusable, can withstand typical laboratory thermal variations in Chemistry processes.
- Lab Addition Funnels Design - The constant pressure addition funnel can keep the internal pressure unchanged, measure the gas volume more accurately .
- Advantages - When adding liquid to an ordinary separatory funnel, it is necessary to open the stopper on the upper end of the funnel or align the groove on the stopper with the small hole on the bottle mouth, so that the liquid in the funnel can flow down smoothly. While the constant pressure addition funnel has an upper connected tube, which can balance the air pressure without opening the stopper.

LABOYLaboy Glass 125mL Addition Graduated Pressure Equalizing Dropping Funnel/Lines with 24/40 Joint at Top & 2mm PTFE Stopcock Chemistry Lab Glassware
Main highlights- 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.
- DIMENSIONS------This graduated addition funnel has a capacity of 125mL,with 24/40 top and bottom joints, with a 2mm PTFE stopcock above the lower male joint.
- 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 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.
