P.I.P. Automatic Pipette Rinsing Set is made from stainless steel for washing different pipettes and some burettes with a maximum length of 600mm. This device has a basket and its design prevents pipettes from breakage or damage. It functions proportional to the water pressure; the nozzle is situated on the top rim and this eliminates back-syphoning as the water inlet is located above and away from any contaminated water. Water constantlay flows among pipettes, then it discharges automatically. It is resistant to most of the common laboratory acids and chemicals.
