The portable vacuum system biovac 106 with integrated resistant diaphragm pump is used for the safe and accurate extraction of liquid, non-flammable supernatants in chemical, biological and medical processes. With various pipettes or glass tips, which are simply inserted into the pipette holder of the handpiece, excess liquids can be easily removed from or from slides, Petri dishes, cell culture vessels, etc. simply removed. Between collecting container and membrane pump sits a filter holder for a replaceable membrane filter. This filter can be used up to a pore size of 0.22 microns depending on the requirements. Depending on the pore size used, it is possible to achieve different separation rates, and thus to reduce the risk of handling bacteria and viruses. The seal between the header and collecting container via a profile seal. The resistant diaphragm pump has a long service life. The connection to the diaphragm pump via a quick coupling, which is provided on the container side with a shut-off valve. Collecting container and pipetting holder (handpiece) are connected via hose. When the connection is disconnected, a hermetic seal is provided by the integrated double-sided sealing hose coupling. The disposal of the trapped in the container and possibly contaminated liquids can thus be hermetically separated. The '' biovac 106 '' is switched on and off directly via the device switch or the optionally available foot switch. The suction system '' biovac 060 '' corresponds essentially to the '' biovac 106 ''. It is the device for dealing with sensitive tasks. An EC motor activates the pump. Via the rotary switch attached to the device, the speed and thus the suction power can be infinitely adjusted. The extraction systems '' biovac ... + '' are provided with an additional filtration attachment. The filtration attachment enables the universal use of these devices. By a small conversion of the functional parts of the collecting container, it is possible to realize filtration tasks. Suction systems '' biovac ... '' can thus be extended by the accessories '' Filtration attachment ''. The user can insert suitable pipetting tips into the holder of the pipette holder.
