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 has a customizable Microinjection System with everything you need to get started. The basic system is shown here. Below you will find many options and accessories to customize your system.

Ultra Micro Pump Nanoliter2020
The world's smallest dead volume (2.7µL) injection syringe system when the 10μL NanoFil syringe is used with WPI needles 33-36g. It comes with various needle sizes from 26 ga. to 36 ga. Versatile research applications are available, including RPE and IO Kits. Custom needle shapes are available —blunt, sharp, beveled. UMP3 is a motorized syringe pump that accepts syringes from 0.5μL–1mL. Using a 10μL syringe, the actual, minimum volume is 5–25nL. For intuitive, intelligent control, the UMP3 is combined with the Micro4 controller. Microprocessor-controlled Nanoliter Injector NANOLITER2020 with SMARTouch controller uses positive dis place ment injection, eliminating the need for pipette calibration. System uses glass micropipettes.
