  1. Affordable New Injector: Configure the PV850 Software
    September 08, 2020
    [by Gabe Gonzalez] 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 8 7PSI. 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

  3. 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.  
  4. 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
  5. Protect Cell Survival and Improve Research Results with Fluorodishes Cell Culture Dishes
    June 16, 2020
    [by Alec Dickson]  WPI's FluoroDish™ tissue culture dishes provide exceptional imaging quality for many applications requiring the use of inverted microscopes such as high-resolution image analysis, microinjection and electrophysical recording of fluorescent-tagged cells. We have a 50 mm diameter dish and two types of 35 mm diameter dishes.        Better O
  6. Long Pathlength Ensures Significant Increase of Sensitivity
    June 15, 2020
    [by Tiana Riggi]  UV/VIS/NIR absorbance spectroscopy is governed by Beer's Law, where the absorbance signal is proportional to chemical concentration, light path length and the compound’s specific molar absorption coefficient. Typical optical pathlengths of cuvettes and flow cells are between 0.1 cm and 10 cm. Longer pathlengths are difficult to achieve due to mechanical constraints. WPI solved this problem with the LWCC Liquid Waveguide Capillary Cells. LWCCs are fiber optic flow cells that combine an increased optical pathlength range from 10–500 cm with small sample volumes ranging from 2.4 µL to about 3 mL. Compared with a standard 1 cm cell you can expect to achieve a 10-500 fold increase in sensitivity.    
  7. WPI's Photonics Center of Excellence Array of Optical Products
    June 15, 2020
    [by Tiana Riggi]  WPI now provides a full range of components and solutions, from proprietary qualified fibers to optical assemblies and fully integrated spectroscopy measurement systems. WPI knows the importance of making measurements where the science happens, and WPI has a full range of reflectance and transmission dipping probes, flowcells and long pathlength liquid waveguide capillary cells, also known as LWCCs with up to 500 cm pathlength that eliminates the need to take a sample to an instrument. Our Photonics Center of Excellence in Friedberg, Germany also allows us to build proven custom configurations quickly. Whether that is a new optical design for a probe, an optical assembly or a customized measurement system.    
  8. WPI Optical Fiber Solutions for Researchers and Product Developers
    June 15, 2020
    [by Tiana Riggi]  From Deep UV to Near Infrared, WPI's optical fiber solutions include a variety of multimode step index designs. In many fields of application in optical sensor and analysis technology, optical fibers and components are required for illumination and for light detection. WPI designs and builds customer-specific fiber assemblies that function reliably with unmatched lot to lot high transmission throughput. Our specialty fiber is one key feature in this in it's the only fiber material currently on the market certified to a DIN standard. The assembly can be a simple 1 fiber patch cord to integrate into your broadband spectrum analyzer to a custom-specific complex fiber transmission probe suitable for difficult environmental conditions. We also offer certified unjacketed bulk fiber.    
  9. Setup WPI CleanRay-2000 Ultraviolet Room Sterilizer
    June 11, 2020
      When your protection from bacteria, molds and viruses is important, WPI's CleanRay-2000 becomes a critical piece of your personal protective equipment. WPI's CleanRay-2000 UV Sterilizer can sterilize a small room in 30-60 minutes. Here we show you how to install the UV bulb in the lamp and setup your unit.          The CleanRay-2000 UV Room Sterilzer is easy to setup. Before you begin, though, we offer a few warnings.  WARNING: THIS UNIT USES UVC LIGHT, WHICH WILL DAMAGE SKIN AND EYES. PEOPLE AND PETS SHOULD NEVER
