![]() ![]() The unit is supplied with an external battery charger. In addition, resistance readings are unaffected by membrane capacitance and membrane voltage.ĮVOM2 is designed with an internal rechargeable 6V NiMH 2700mAH battery pack. The EVOM2 produces an AC current that avoids electrode metal deposits and adverse effects on tissues, which can otherwise be caused by a DC current. ![]() When combined with WPI’s Endohm chamber, the EVOM2 can also be used to perform trans endothelial electrical resistance measurement. The EVOM2 qualitatively measures cell monolayer health and quantitatively measures cell confluence. The confluence of the cellular monolayer is determined by an increase in TEER detected using the unique electronic circuit of the EVOM2 and STX2 electrode (included with the instrument). INTRODUCTIONEVOM was the first instrument designed to perform routine Trans Epithelial Electrical Resistance (TEER) measurement in tissue culture research. 1–The EVOM2 measures resistance or voltage across a tissue membrane.
