PFA gas washing bottle is a vessel used to remove impurities from gases. It involves bubbling and absorbing impure gases through a selected suitable liquid medium (dissolution or chemical reaction), in order to wash away impurities and achieve the goal of purifying gases. When designing, the surroundings of the PTFE balls are covered with small holes. In general, long catheters come in and short catheters come out. #gaspurification #reactionbottle #PFAvessel
