World Precision Instruments (WPI) offers a broad range of research instruments for zebrafish (Danio Rerio) research, from the time the genetics of the subject are modified through the point where the physiological effects of the change are monitored. Whether researchers are performing microinjection or making cardiovascular measurements, the WPI product line includes instruments for research on oocytes, embryos, larvae and adult zebrafish.
Enhanced Microinjection Efficiency for Genetic Modification
The customizable Zebrafish Microinjection Toolbox includes...more

The PV850 Injector is designed to simplify intracellular injection and a variety of other microinjection tasks. The PV850 uses regulated air pressure for injecting cells with fluid. Injected volumes range from picoliters to nanoliters. The port supplies positive pressure for high-pressure ejection maximum of 87 PSI. The PV850 Microinjector offers separate regulated compensation (back filling prevention) and ejection pressures with a precision timing circuit that switches from injection pressure to compensation pressure automatically. Timing, injection pressure and compensation pressure are adjusted independently using the intuitive touch-screen user interface. Time intervals can range from 2 seconds down to 10 ms or less, depending on the injection pressure setting...more

Easy to Configure Using the SmartTouch Interface
The UMP3 UltraMicroPump is easy to configure using the SMARTouch interface. It is pre-programmed for popular microsyringes and allows for user-defined syringe parameters, too. This ensures nearly universal compatibility. You can control up to two pumps, either simultaneously or independently, and the optional foot switch means hands-free operation. You can instantly verify actual injection volume on the graphical display. You can even use the touch screen while wearing gloves.
Ensure Reliable Injections of Small Volumes
The extremely fine thread-pitch of the UMP3 drive shaft ensures reliable injections of small volumes. When you are using a 10-microliter syringe...more

The new WPI MICRO-ePORE™ pinpoint cell penetrator is a simple and versatile system that can be used to facilitate microinjection of a diverse array of compounds and biomolecules into oocytes and pre-implantation stage mammalian embryos. Patent pending Flutter Electrode Technology assists in small, clean, precise membrane penetration without tearing or damaging the membrane. It results in substantially increased viability of embryos. In this quick video, Dr. Pelczar from the Center for Transgenic Models in Switzerland demonstrates the ease of cell penetration using the new MICRO-ePORE™.
