As WPI’s EVOM™ line of TEER/TER (Transepithelial Electrical Resistance) measurement meters continues to evolve, we have seen similar advancements in the design of its electrodes. The new STX4 electrode (EVM-EL-03-03-01) (LINK) offers many advantages over the STX2-PLUS released in 2020. Both the STX4 and the STX2-PLUS are improvements on the STX2 and STX3 designs used with the EVOM, EVOMX, MilliCell® ERS and ERS2, and EVOM2. In this article we will compare the two newest designs.

WPI’s EVOM™ Manual is the gold standard for delivering stable and repeatable Trans Epithelial Electrical Resistance (TEER) measurements. The EVOM™ Manual is the newest TEER meter. It qualitatively measures cell monolayer health and quantitatively measures cell confluence by determining an increase or a plateau in tissue resistance detected using our innovative EVOM™ technology. WPI’s state of the art EVOM™ technology provides you with real-time, valuable feedback during experimental measurements.
Electrode options are available for use with the new EVOM™ Manual. Here we will compare these options so you can choose one that’s right for your application.

The ATC2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. It has three modes of operation, which we discuss here.
Normal mode compares the temperature and the setpoint for PID control. Adaptive mode is ingenious. It uses the monitored animal temperature and the actual plate temperature to define an offset value which is used to adjust the PID parameters. That offset is recalculated at a set interval for extremely precise control. Shutdown mode is a fail safe that shuts the unit down if the plate temperature reaches a defined setpoint (like 45ºC) that would endanger the animal.

REMS AutoSampler is an automated TEER measurement system that uses a robotic arm to make measurements in 24- and 96-well plates. This article details how to upgrade the software for a REMS system.
Considerations Before You Begin
The first consideration is the hardware in your REMS system and the software version you are running.
Systems Older than 2014
- If your system was purchased before 2014, the REMS will have a PCI6023 data card, and you may only upgrade to the REMS4 software. See below for instructions on verifying your software version.
- To upgrade to the current version of the REMS software (REMS6.02), a unit purchase before 2014 will need a PCI6220 data card. You may purchase the upgrade kit (WPI# 300555), which includes the board/data card (for example, NI PCI6220), a new interface cable and software version 6.0.2.
In addition, you need a newer computer with free PCI slot. WPI’s current REMS computer...more

The ATC-2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. The ATC-2000 uses a digital PID controller to regulate the application of power to the heating plate to achieve the desired temperature at the monitored sensor. PID stands for Proportional, Integral and Differential. If the factory default PID settings do not adequately stabilize the system, you can manually adjust the PID parameters. WPI doesn't reccomend changing these parameters manually unless you are familiar with the functions of each PID parameter.
