Sartorius Water Jet Pump. With g ¾ Female Thread

Water jet pump with G3/4 female thread

The Microsart^® e.jet vacuum laboratory pump is designed to create sufficient vacuum for filtration and unlike traditional vacuum pumps, it allows simultaneous transfer of the filtered liquid to waste. The Microsart^® e.jet Transfer Pump is ideal for sample filtration in Microbiology achieving a trans membrane pressure below 700 mbar in compliance with ISO 8199 (Water quality - General guidance on the enumeration of micro-organisms by culture). Constant flow rates and a defined maximum vacuum guarantee smooth and reliable filtration. The Microsart^® e.jet Transfer Pump greatly reduces operating complexity and is an ideal accessory for 3-branch and 1-branch manifolds. The Microsart^® e.jet is designed to pump both gas and liquids, meaning no loss of efficiency or malfunctions from water drawn into the pump head.

The vacuum pump series Microsart^® maxi.VAC and Microsart^® mini.VAC provide up to date technology for daily use in the Microbiology laboratory environment. They are electric neoprene membrane pumps and therefore oil- and maintenance-free with a low noise level. The vacuum produced by these pumps is controlled and can be easily adjusted to your specifications. Thus sensitive cells (e.g. bacteria) are concentrated on the surface of a membrane filter under better conditions, which results in decreased mortality of the cells, higher recovery rates and shorter incubation times.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. Alternatively, the use of a Woulff’s bottle makes a visual control possible. Such a bottle is also useful for a simple adjustment of vacuum with filter holders without a tap for vacuum control. Systems with manifolds Polycarbonate holders type 16511 can be fitted directly onto 3- or 6-branch manifolds. Glass holders require adapters. Also stainless steel holders can be mounted by using adapters and multi-manifolds. The complete manifold systems described on the previous page are far less expensive and more convenient to use. Additionally, a vacuum hose and a source are required. When an electrical pump is used, a vacuum resistant container must be inserted between manifold and pump. The insertion of a Vacusart unit in the vacuum line between the container and the pump is recommended. Further useful accessories Forceps are very important for the use of the membrane filters.
