  1. Setting Up The MICRO-ePORE
    June 19, 2019
    The new WPI MICRO-ePORE™ Pinpoint Cell Penetrator is a simple and versatile system that can be used for efficient 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. Here Gabe sets up the system and connects all the components. Unpacking Your MICRO-ePORE™ System Connecting Your MICRO-ePORE™ System Connecting the MICRO-ePORE™ Electrode Holders
  2. Setting Up the DUO773 Electrometer
    June 19, 2019
    For intracellular dual or differential studies, WPI's Duo773 has separate negative capacity controls and built-in active filtering that allows the precise balancing of time constants for artifact-free differential measurement. It comes complete with two probe headstages, 1015Ω and 1011Ω probes to monitor signals from ion-specific micro-electrodes as well as KCl-filled electrodes. Jim shows you how to safely unpack and properly setup your new Duo773. Unpacking Your MICRO-ePORE™ System More Info

  4. 7 Reasons to Love the NEW EndOhm Chambers
    May 02, 2019
    EndOhm Chambers Re-engineered EndOhm chambers are designed for making accurate TEER measurement of epithelial and endothelial cell cultures. The design keeps the top and bottom electrodes at a fixed gap and maintains the sample (cell culture insert) in a centered position inside. This design minimizes the variability associated with electrode positioning and gap, making EndOhm chambers more accurate and capable of generating reproducible results. WPI made some recent upgrades to the EndOhm chambers. The NEW EndOhm Chamber is made of GLASS, making it easier to clean and more crack resistant. The chamber can be cleaned with ethanol, isopropanol, bleach, etc.
  5. FAQs about Metal Microelectrodes
    April 30, 2019
    Here are some frequently asked questions (FAQ) about Metal Microelectrodes. What metal type is best for my application?W- Tungsten Tungsten is a versatile and widely-used microelectrode material that offers a good balance between performance and cost. ADVANTAGES DISADVANTAGES Extremely strong and stiff metal provides probes with exceptional rigidity. Great for acute and chronic recording due to biocompatibility and lower cost. High corrosion resistance offers consistent long-term performance. Does not provide the same degree of electrochemical performance or stability as platinum-iridium alloy, making it a poor alternative for microstimulation. Lower charge transfer capacity of tungsten will result in larger, potentially
  6. How to Clean Surgical Instruments Using an Ultrasonic Cleaner
    March 13, 2019
    Prior to sterilizing surgical instruments, it is a good idea to make sure you have cleaned them to remove blood, tissue and all other organic material.  If soiled materials dries or is baked onto the instruments, it will interfere with microbial inaction and can compromise the sterilization process. Cleaning is the removal of foreign material (e.g., soil and organic material) from objects and is normally accomplished using water with detergents or enzymatic products. The most common type of mechanical automatic cleaner is the ultrasonic cleaner. Ultrasonic cleaners are used in conjunction with detergents and enzymatic cleaners.  Ultrasonic cleaning removes particulates by cavitation (bubbles) and implosion. Waves of acoustic energy are transmitted in aqueous solutions and disrupt the bonds that hold particulate m
  7. What's the Difference between Hanging and Standing Cell Culture Inserts used in EndOhm Chambers
    February 22, 2019
    WPI EndOhm chambers are used with WPI's EVOM2 meter for making TEER (transepithelial electrical resistance) measurements. Here Subhra shows the difference between hanging cell culture inserts and standing cell culture inserts.
  8. Prevent Damage to Snapwell Inserts by Using STX3 Electrode
    February 21, 2019
    The WPI EVOM2 meter is used to measure TEER (transepithelial electrical resistance) in cell culture inserts. The STX2 electrodes with a static length may cause damage to Snapwell inserts. Here Subhra demonstrates how to use the adjustable STX3 electrode to prevent damage to your cell culture inserts.
  9. Choosing an EndOhm Chamber Compatible with your Cell Culture Inserts
    February 21, 2019
    WPI's EndOhm chambers are used with WPI's EVOM2 meter to measure TEER (transepithelial electrical resistance) in cell culture inserts. Three chamber sizes are available for 6-well plates, 12-well plates and 24-well plates. Here Subhra demonstrates how to choose an EndOhm chamber to match the cell culture inserts you are using.
  10. Resurfacing Electrodes in a WPI EndOhm Chamber
    February 21, 2019
    WPI EndOhm chambers are used with WPI's EVOM2 meter for making TEER (transepithelial electrical resistance) measurements. After heavy use your background resistance measurement may start to rise. Your electrodes may need to be resurfaced to remove buildup of proteins, sugars and biological materials. Here Subhra demonstrates how to clean and resurface your EndOhm chambers.
