 Zebrafish Model Organism

Zebrafish (Danio Rerio) are rapidly gaining in popularity as bio-medical research subjects because of the ability to generate high resolution, in vivo images of the embryos. Zebrafish are easy to maintain and produce a large number of offspring. Additionally, the embryos have a nearly transparent skin, making their development easily visible. These fish are used for a variety of disciplines, including neuroscience, genetics and aging studies.

Empowering scientists with reliable instruments

Serving scientist for over 50 years, WPI offers a variety of instruments for Zebrafish microinjection including pumps, pipetters, microscopes and more. One of our most popular pumps for microinjection is the PV820 Pneumatic PicoPump.

The PV820 and PV830, Pneumatic PicoPumps, were designed to simplify intracellular injection. You get repeatable microinjection in volumes ranging from picoliters to nanoliters. PV820 offers eject and hold pressure. The hold pressure prevents backfilling of the pipette by capillary action. 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 volume injected is controlled by the inside diameter of the glass tip, the pressure and the time.

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 you may use to customize your system.


You may customize your system using the following options:


  • PZMIII Precision Stereo Zoom Microscope on Track Stand
  • PZMIV Precision Stereo Zoom on Track Stand
  • 504928 LED Lighted Microscope Stand, 12.5"
  • 504929 LED Lighted Microsccope Stand, 10.5"
  • 504596 Halogen Lighted Microscope Stand



  • M3301 Manual Micromanipulator
  • KITE Manual Micromanipulator


Ultra Micro Pump Nanoliter 2010
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. The Nanoliter 2010 system is perfect for applications in the 2.3–69nL range, with fast, accurate 2.3nL aliquot injections. It can be combined with the Micro4 controller.
