High quality and high speed. Solves the problem of washing pipettes up to 600mm long and Mohr burettes quickly and safely. Indispensable in the laboratory where radioactive, caustic and toxic materials are in use. The PE rinser fills via the spray nozzle situated on the top rim. This eliminates backsymphoning as the water inlet is located above and away from any contaminated waters. Contaminated waters will syphon out totally, once the syphon point at the top of the rinser has been reached, via the large diameter drain situated at lowest point, before refilling automatically. During washing the pipettes/burettes are housed in specially designed baskets which minimise breakages as it buffers the tips of pipettes against the soft PE base. Since soaking takes the longest time, two or three baskets of pipettes/ burettes can be soaking in their jars whilst another basket full is being washed in the rinser. On the bottom connection for outlet tubing (not included; Ø inner tube: 13mm).
