SYS-PV820
The World Precision Instruments Pneumatic PicoPump PV820 uses differential pressures to hold liquid in the glass needle between injections. The user manually controls short bursts of gas pressure to expel the liquid – allowing delivery of sub-nanoliter volumes. The amount of liquid delivered depends on two main variables – the size of the glass needle opening and the amount of time injection pressure is applied. set the instrument to 100 ms "TIMED" mode.
