EVOM Manual - TEER Measurement Device

Overview

TEER measurement device with automatic data logging.

This manual TEER measurement meter now has automatic data logging. EVOM™ Manual has a low noise design that offers greater resolution and accuracy in your TEER measurement protocol. It has automatic 20X sample averaging, which improves accuracy and stability. Choose from the adjustable fixed measurement currents (2, 4 or 10 μA). Resistance measurements auto range from 1 Omega to 100,000 Omega or with three fixed current ranges. The reliable low current, low voltage design prevents metal ion transport, and it has fast resistance stabilization on low levels under 200 Omega with resolution to 0.1 Omega. Use the ergonomic tilt stand for low glare operations. You get automatic plate indexing operation with or without control well subtraction for resistance and potential difference (PD) measurements, and continuous data logging via USB (PC, Mac, Linux).

EVOM™ Manual For TEER Measurement

The EVOM™ Manual delivers improved workflow efficiency, more stable and repeatable measurements versus traditional Trans Epithelial Electrical Resistance (TEER) meters. Providing you with vital feedback during experiment measurements, the EVOM™ Manual’s large screen offers a range of informational views. The new graphical displays for trend analysis and measurement values helps scientists deliver simple, stepwise methodology during experimental measurements. The touch screen interface provides you with an intuitive, easy-to-use menu for configuration.

Eliminating 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. When used with the footswitch it enables hands-free recording of measurements.

At the heart of the EVOM™ Manual is our latest processor and circuitry, providing users with quick, easy and reliable readings due to its fast stabilization, automatic twenty times sampling average and low noise design. The auto ranging resistance feature allows for fast resistance measurements, and an over-range display feature eliminates false readings. 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 KOmega .

TEER Measurement Electrode

The STX4 electrode (not included) was designed for easy insertion into many 24-well plates. It is location re-placeable in the insert for repeatable and consistent measurements. The new shielded electrodes are now designed to minimize electrical interference and to be more easily maintained.

• STX4 new electrode designed for 12 and 24-well plates
• Weighted self-standing electrode for hands-free stable measurements
• Shielded cable to minimize electrical and cell phone interference
