<p>The fluid removal unit contains a pump head (14) having suction and pressure connection (16, 17) and a nozzle formed by the outlet of the water tap so that a spray jet can be directed onto the pressure connection (17) transverse to the suction channel (16). Thus the outlet head which fits tightly in the pump head can be used to supply the fluid which is drawn off to the pressure connection via the suction pipe which is associated with the pump head. To empty the cuvettes or the like which can be built into the work bench, the suction pipe n19) which is firmly associated with the pump head can be used as a rake or poker. The suction and pressure levels required can be easily reached without any special installations.</p> |
