The funnel wall has no adhesion and adsorption to the solvent, can be completely emptied, the interface is clearly visible, and the sealing is good, which can prevent the penetration of chemicals in the separatory funnel; the piston device is easy to remove and easy to clean; It is convenient for the user to observe the liquid change in the cavity during the actual sample separation; the control valve made of high-purity experimental grade PTFE can flexibly control the flow; compared with the glass separatory funnel, the advantage is that it can separate hydrofluoric acid, and It is not easy to damage, can be used for a long time, the inner wall is smooth, does not adhere to any substances, and is easy to clean.

PFA gas scrubbing bottle is a vessel for washing impurities in gas. It absorbs impure gas by bubbling (dissolving or due to chemical reaction) through a selected suitable liquid medium, so as to wash away impurity gas, and get the purify gas. During the design process, the tetrafluoro balls are surrounded by small holes. Pay attention: 1. The gas scrubber is filled with the selected liquid to scrub the gas and remove the moisture or other gas impurities. When using, pay attention to the flow direction of the gas, the inlet pipe and the outlet pipe cannot be reversed; 2. The gas washing bottle cannot hold alkaline liquid detergent for a long time. After use, pour the detergent into a reagent bottle with a rubber stopper and store it for later use, and clean it with water. The bottle can also collect gas and calculate the volume of gas.
