Download Microinjection Systems Brochure   Empowering Scientists with Reliable Instruments Serving scientists for over 50 years, WPI offers a variety of instruments for microinjection including pumps, pipetters, microscopes and more. One of our most popular pumps for microinjection is the PV850 Pneumatic PicoPump. The PV850, PV830, uPump and MICRO-ePUMP were designed to simplify intracellular injection. You get repeatable microinjection in volumes ranging from picoliters to nanoliters. The volume injected is controlled by the inside diameter of the glass tip, the pressure and the time. The PV850 offers eject and hold pressure. The hold pressure prevents backfilling of the pipette by capillary action, ensuring repeatable injections. In addition, the PV830 also has vacuum pressure which allows you to securely hold a cell with one pipette while you inject it with another.  The uPUMP and MICRO-ePUMP have a built in pressure source, eliminating the need for an external pressure supply. The MICRO-ePUMP with Integrated Cell Penetrator and Internal Pressure Source is perfect for intracellular injection. The Cell Penetrator delivers a highly localized voltage signal to a targeted injection site to facilitate penetration with minimal trauma. WPI h
  2. Setting up the WPI PicoPump
    September 03, 2020
    Designed to simplify intracellular injection and a variety of other micro­in­jec­tion tasks, WPI’s PicoPumps (PV830 and PV820) use precisely regulated pres­sures for se­cur­ing cells and injecting them with fluid. Injected volumes range from picoliters to nanoliters. Separate ports supply positive and negative pressure—pos­i­tive pressure for high-pressure ejection, and suction for supporting the cell or for filling the pipette from the tip. In this quick series, you can see how to setup a PicoPump. 1. What's Included with a PV Pump In this first video (#1) you can see all the components of the system as they unpack the system.
