EVOM™ Electrode Test Solution Kit

The kit contains 5 different ionic solution bottles (potassium chloride: KCl) 125 mL each. Kit includes Description EVM-AC-03-05-01 EVOM Test Solution A, 32X EVM-AC-03-05-02 EVOM Test Solution B, 16X EVM-AC-03-05-03 EVOM Test Solution C, 8X EVM-AC-03-05-04 EVOM Test Solution D, 4X EVM-AC-03-05-05 EVOM Test Solution E, 2X Note : X=10 mM (Multiply X with 10mM to calculate the concentration: e.g., 32X= 320 mM) The kit can be used to verify proper functionality of EVOM™ Manual and EVOM™ Auto systems including electrodes. The kit can be used to test EVOM™ Manual electrodes such as, STX4, ENDOHM Chambers, STX HTS electrodes and EVOM™ Auto electrode arrays for 96 HTS and C24 and M24/O24 HTS well plates. Application Use the solution kit to verify the resistance values for a specific electrode are within the acceptable range. Measure resistance values at different concentrations. Electrical resistance values should decrease with increasing ionic concentrations. Plot ionic concentration vs resistance as a scatter plot. Fit a trend line as power fit. R² value greater than or equal to 0.98 indicates normal functionality. This kit helps to confirm whether EVOM™ instrument/system is performing as per WPI’s specifications or the EVOM™ electrodes need cleaning, maintenance or replacement. Use this kit to verify EVOM™ instrument function daily or weekly or periodically or as needed. WPI recommends performing instrument reading verification at least once a week when used regularly. Erratic TEER readings collected with known samples would require EVOM™ system to undergo the verification testing using this kit. Additional Details Solutions should be discarded after use. Solutions of the kit are tested and verified by WPI using an EVOM™ Manual and a STX4 electrode. Certificate of Test Solution Analysis/Verification is provided with the kit. Individual concentration bottles are not sold. It is offered as a kit only. EVOM™ Electrode Test Solution Kit Instruction Manual
