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

With the first approved human gene therapy trial in 19891 (Rosenberg, et.al.), gene therapy has come a long way in modern medicine and is making inroads in clinics and the market in general.2,3 2017 was an important year for gene therapy when Luxurna, the first human gene therapy drug for an inherited retinal dystrophy, was approved by Food and Drug Administration (USA).4 Now several drugs are undergoing clinical trials. With an estimated $11 billion (USD) market in the next 10 years, both clinical trials and the pharmaceutical industry are expected to benefit immensely from gene therapy.5
With improved use of viral vectors (Adeno-associated virus (AAV), adenovirus, lentivirus, retrovirus, HSV) or non-viral vectors, research and clinical trials on the development of therapeutic genes have witnessed great success. Viral vectors have been employed for the treatment of various diseases such as metabolic...more

The type of pump you choose for your fluid handling will largely depend on your laboratory application. In this article, we will compare the popular pump types.
Microinjectors
WPI Microinjectors use carefully regulated air pressure for injecting cells with fluid. Injected volumes range from picoliters to nanoliters. The port supplies positive pressure for high-pressure ejection. The pressure port maintains a low positive “compensation” pressure to the injecting pipette between injection pulses to prevent fluid uptake through...more

First, let's consider volumes. - A milliliter (mL) is one thousandth the volume of a liter (L) or 10-3L
- A microliter (µL) is one thousandth the volume of a mL (10-6L)
- A nanoliter (nL) is one thousandth the volume of a µL (10-9L)
- A picoliter (pL) is one thousandth the volume of a nL (10-12L)
This is graphically represented at the right. Notice that the mL is one trillion times larger than the picoliter. The table (right) shows that the side of a cube with a volume of 1mL is 1cm long. Likewise, the side of a cube with a volume of 1pL is 10µm long. Just for comparison, it shows that the diameter of a sphere with a volume of 1mL is 1.24cm, and the volume of a sphere with a volume of 1pL is 12.4µm.
With these volume comparisons in mind, lets consider some of the available options for microinjection pumps.
