![]() The EVOM Manual has adjustable current levels in three fixed ranges with two lower ranges for sensitive membranes and high resistance ranges up to 100 KΩ.įor further information please contact us or download the datasheet. The unique electronic circuit of the EVOM2 and the included STX2 elec-trode detect the confluence of the cellular monolayer. The EVOM2 not only qualitatively measures cell monolayer health, but also quantitatively measures cellular confluence. The auto ranging resistance feature allows for fast resistance measurements, and an over-range display feature eliminates false readings. EVOM2 is the next generation, redesigned for ease of use. When used with the footswitch it enables handsfree recording of measurements.Īt the heart of the EVOM Manual is WPI's latest processor and circuitry, providing users with quick, easy and reliable readings due to its fast stabilisation, automatic twenty times sampling average and low noise design. TEER is easily computed by applying a unit area formula to the resistanceĮliminating the need to log data by hand, the EVOM Manual writes the resistance or voltage information to a USB drive in CSV format for easy transfer to spreadsheets and data analysis programs.Prevent data loss with auto save and data recovery when battery is low.The small footprint allows more bench space.Auto data logging eliminates the need to track data by hand.Eliminates errors and reduces experimental processing time.Solute permeability was assessed using fluoresceinated dextran-70 (1 mg/ml, Sigma Inc., St. The touch screen interface provides users an intuitive, easy-to-use menu for configuration. TEER was measured using an EVOM voltohmmeter (World Precision Instruments Inc., Sarasota, FL). The new graphical displays for trend analysis and measurement values helps scientists deliver simple, stepwise methodology during experimental measurements. The results were presented as a percentage compared to the normal HBMECs without NCI-H209 cells treatments. The nal TEER values were calcu-lated as ohm cm2 by multiplying it with the surface area of the monolayer. l Millicell ERS Voltohmmeter or EVOM Voltohmmeter. TEER was measured using an EVOM voltohmmeter (World Preci-sion Instruments, Sarasota, FL). ![]() The EVOM TM Manual delivers improved workflow efficiency, more stable and repeatable measurements versus traditional Trans Epithelial Electrical Resistance (TEER) meters. Providing users with vital feedback during experiment measurements, the EVOM Manual’s large screen offers a range of informational views. 2.4 Materials for Permeability and TEER Measurement l l Electrode probes (World Precision Instruments). ![]()
