Over time, you may experience mechanical drift in one or more of the axes of your manual micromanipulator. Here we show you how to adjust for that. The process is similar for other styles of manual micromanipulators. We will look at the process for adjusting all three axes of a KITE micromanipulator.
Let's talk about mechanical drift on a micromanipulator and how to correct it. In this demonstration, we will use the popular KITE. A manipulator axis may begin to move gradually under its own weight, even if it's not being touched. This is called mechanical drift, and it happens from normal use of the manipulator over time. Each course axis control on the micromanipulator has its own adjustments. This procedure is very similar to the one we used for adjusting an M3301 micromanipulator. It also...more

Magnetic stands act as an invaluable extra hand around the laboratory to hold an electrode, digital dials or tools. The base houses a strong magnet which can be activated by turning the switch. Position the magnetic stand on a weighted steel base plate or metal desk and rotate the dial counter-clockwise to engage the magnet. We offer multiple styles of magnetic stands, but these videos show a couple options.
Flexible Magnetic Stand
The M11 Flexible Magnetic Stand is ideal for probe holders and other lightweight objects. The flexible arm bends like a snake and locks into position with a flick of the control lever. Here we show you how easy it is to set it up.
Magnetic Stand with Adjustment Arm
The M9 Magnetic Stand has an adjustment arm. We'll show you how to easily position it...more

WPI pre-pulled pipettes (MicroTips) are a popular choice for pharmaceutical companies carrying out CCIT (Closed Container Integrity Testing). Each MicroTip is individually tested and inspected and can be shipped with a certificate of compliance.
CCIT is an important part in understanding the biological safety and...more

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

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.

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
