  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. How to Set the Gap on your WPI EndOhm Chambers
    February 21, 2019
    WPI EndOhm chambers are used with WPI's EVOM2 meter for making TEER (transepithelial electrical resistance) measurements. Each EndOhm chamber comes with a "spacer" disk for calibrating the gap between the two chamber electrodes. A consistent gap ensures reliable measurements. Here Subhra shows how to calibrate your chambers.
  6. Using WPI's PUL-1000 Micropipette Puller
    March 06, 2015
    World Precision Instruments' PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes used in intracellular recording, microperfusion and microinjection. It offers programmable sequences of up to four steps with complete control over the heating, force, movement and cooling time. This allows graduated cycles for a variety of applications. PUL-1000 can produce pipettes with tip diameters from less than 0.1µm to 10+ µm.  More Info
