SEPARATE LIQUIDS WITH PRECISION: Purer extractions lead to more accurate work. Precisely separate compounds using the glass separator funnel and the leak-proof PTFE stopcock. The separation flask is designed for solvent/liquid-liquid extraction and is an essential tool in any lab. We recommend you run an extraction at least 2-3 times for the best results (distillation may be needed to remove impurities).

24/40 joint top and bottom,Pressure equalizing,Cylindrical style with PTFE stopcock

Capacity:500ml

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 125mL,with 24/40 top and bottom joints, with a 0-4mm high vacuum valve above the lower male joint.

Made of high quality, Borosilicate glass

Cylindrical Dropping Funnel, made of high quality borosilicate glass

Open top with PTFE Key Stopcock

Design: Comparing to an ordinary dropping funnel, the pressure-equalizing dropping funnels have an additional narrow-bore glass tube from the upper part of the funnel bulb to the ground glass joint around the stem at bottom. The pressures in the reservoir and the reaction flask are equal, and liquid will flow into the reaction flask even when the stopper is in place in the funnel. Pressure-equalizing dropping funnels are normally only used for inert atmosphere reactions.

Advantage: 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 dropping funnel has an upper connected tube, which can balance the air pressure without opening the stopper.

High Quanlity: Made of high-quality glass, durable and of high quality, can withstand typical laboratory thermal variations in Chemistry processes.

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.

Design - The constant pressure addition funnel can keep the internal pressure unchanged, measure the gas volume more accurately .

Premium Material - Made of high-quality glass, durable and reusable, can withstand typical laboratory thermal variations in Chemistry processes.
