17004, Stopper for 1 l Suction Flask 16606

System with suction flask Sartolab RF complete units, the all-glass filter holder type 16309 and the 47 mm polycarbonate holder type 16510, are supplied with a filtrate receiver flask and can be connected directly to the vacuum source with a vacuum hose. All other holders must be fitted onto either a suction flask or a manifold. Additionally to the vacuum hose and source, a suction flask and a suitable bored stopper is necessary. The vacuum source can either be an electrically driven pump, a water jet pump or a hand operated pump. Avoid liquid filtrate flowing into the electric pump. This can be achieved by using a Vacusart unit with hydrophobic PTFE filter when the suction flask is filled or foamed over. When a water pump is used, this combination avoids that water flows back into a suction flask.
