Gilson pipetman pipet pipette P200 200 ul variable volume ejector P20 ol2

Two used Gilson pipetmans. model P200 (20-200ul) and P20 (2-20 ul) in the old style with tip ejector. The pipettors sold have been used only with non-radioactive and non-biohazardous materials. Also. all pipettors have been tested to work properly- I have measured the aliquottes on a Mettler scale.
