Stainless Steel Holder with 200 ml capacity, for the filtration of up to 5 Liter volumes. A practical holder for a lot of laboratory filtrations. It can be attached to a tripod with the help of a steel rod which can be screwed in. The hose nipple is screwed into the side of the top part in order to leave room for a large filling opening. This simplifies the pouring-in of the sample and the sample can be refilled without removing the tube connection to the pressure source. Leak-proof sealing is achieved by hand-tightening of the closing ring. For the filtration of small volumes ( up to about 200 ml soil samples or viscous liquids, such as oils), the holder is connected directly to a pressure source. For the filtration of up to 5 liter volumes of relatively easily filterable liquids (e.g. buffer solutions, solutions for cell counters and tissue culture solutions), it is used in combination with a pressure tank.
