  1. Setting up the WPI PicoPump
    September 03, 2020
    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. 1. What's Included with a PV Pump In this first video (#1) you can see all the components of the system as they unpack the system.  
  2. Popular UMP3 Injector is Not Your Ordinary Syringe Pump
    July 13, 2020
    [by Alec Dickson] 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
  3. Versatile Microinjection Syringe Pump (UMP3T) for Injections in the Nanoliter to Milliliter Range
    May 15, 2020
    The UltraMicroPump3 is a versatile microinjection syringe pump designed to support the needs of a busy lab. The UMP3 Microinjector is suitable for delivery of media from nanoliters to milliliters. the UMP3 injecotor’s user interface and system design enables delivery of highly accurate and repeatable injections. The choice for thousands of scientists, it is widely cited in research papers.   Intuitive Touchscreen Display for Easy Setup The SMARTouch controller has an intuitive touch screen interface and an easy-to-use menu for quick configuration of the syringe size, volumes and f
  4. Genetic Transfer (viral or non-viral vector) Using Microprocessor-Controlled Injector
    March 02, 2020
    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
  5. Choosing a Pump for your Fluid Handling Application
    October 04, 2015
    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. Peristaltic Pumps A Peristaltic Pump has a series of rollers that rotate around the edge of the pump head. A flexible tubing is threaded around the rollers and pressed up tight next to them, pinching the tubing where it contacts a roller. As the rollers rotate around the head, the fluid in the tubing moves from the input to the output. The rate of head rotation and the size of the tubing determine the volume of fluid that can
  6. When a Bigger Bolus is Better
    June 12, 2015
    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

  8. Nanoliter Troubleshooting
    May 01, 2013
    The Nanoliter injector is a micro-processor controlled injection system that uses direct piston displacement. The collet assembly (exploded view) is shown in the image below. The glass pipette fits into the white, plastic sleeve (spacer). When the collet is screwed in place securely, the black rubber washers are compressed and hold the glass firmly in place. Nanoliter 2000 A side view of the assembled Nanoliter injector is shown below. Nanoliter 2010  As the plunger is depressed, it pushes into the glass to expel the liquid in the pipette. Eventually, the diameter of the plunger matches that of the glass,
  9. Choosing the Correct Pump
    April 29, 2013
     WPI carries a wide variety of fluid handling tools utilizing three different technologies: peristaltic pumps syringe pumps pneumatic injectors The range of applications and the criteria used to select a particular pump or injector is broad and complex, and we encourage you to phone (866.606.1974 in the USA) or email (customerservice@wpiinc.com) us and speak to a technical support specialist. In the meantime, we have tried to simplify the process by listing all of the pumps
