The ENDOHM-24 (#EVM-EL-03-01-03) is compatible with the following chambers: Corning Endohm chambers may be sterilized with EtO, alcohol or a bactericide not autoclavable. To date, cups from Corning, Millipore, Nunc, Greiner and BD Falcon have been tested.

Endohm together with EVOM™ Manual offers the most accurate and economical endothelial ohmmeter now available. Because of the uniform density of the AC square wave current from EVOM™ Manual errors owing to electrode polarization or membrane capacitance are largely eliminated. Compared with other resistance measurement methods, Endohm with EVOM2™ offers a much more convenient and economic solution to “leaky tissue” measurement. With Endohm’s fixed electrode geometry, variation of readings on a given sample is reduced from 10-30 Ω with STX2 electrodes (depending on the experience of the user) to 1-2 Ω. The background resistance of a blank insert is reduced from 150Ω (when using WPI’s hand-held STX2 electrodes) to less than 5 Ω. Make more precise measurements with EndohmsĮndohm’s symmetrically opposing circular disc electrodes, situated above and beneath the membrane, allow a more uniform current density to flow across the membrane than with STX2 electrodes. The height of the top electrode can be adjusted to fit cell culture cups of different manufacture.

The chamber and the cap each contain a pair of concentric electrodes: a voltage-sensing silver/silver chloride pellet in the center plus an annular current electrode. Transfer cups from their culture wells to the Endohm chamber for measurement rather than using hand-held electrodes. Using WPI’s EVOM™ Manual resistance meter, Endohm chambers provide reproducible resistance measurements of endothelial and epithelial monolayers in culture cups.

TEER measurement for removable culture cup systems using EVOM2™ meters for endothelial and epithelial cell cultures.

Simple test procedure to verify electrode performance.

Tri-leg supports offer mechanical stability and the membrane is held parallel to the electrodes (G version).

Symmetrical electrode pattern disperses test current uniformly.

Can be used with 6, 12 or 24 well plates with removable inserts.

Stability and reproducibility superior to the STX2 electrodes to 1% tolerance.

Three sizes cover a range of well cup sizes from a variety of manufacturers.

New insert holder with 120º tri-supports for three leg inserts.

Crystal clear glass chamber allows visualization of apical electrode positioning.

The glass chamber is easier to clean and more crack resistant than the prior version.

The new EndOhm chamber upper mount is made of polycarbonate and unaffected by alcohol.
