PTFE Constant pressure dropping funnel 100ml 250ml

The Constant pressure dropping funnel, also known as constant pressure separating funnel, is also a kind of separating funnel. It can perform liquid separation, extraction and other operations. But different from other separatory funnels, the constant pressure separatory funnel can keep the internal pressure unchanged. First, it can prevent back suction. Second, it can make the liquid in the funnel flow down smoothly. Third, it can reduce the pressure of the increased liquid on the gas. effect, so that it is more accurate when measuring gas volume.

The constant pressure dropping funnel includes a bucket body and a bucket cover. A piston with a two-way structure is installed on the lower opening of the bucket body, and the two-way connections of the piston are respectively connected with the two lower pipes. This product can facilitate the control of the experimental operation process and reduce the labor intensity. When the amount of liquid to be separated is large, the two liquids in the bucket can be simultaneously flowed to the lower pipe by simply turning the tee of the piston, without changing the container. Finished at once. The device is an experimental vessel with better functions in scientific research and chemical experiments.
