One of our frequently asked questions (FAQs) concerns TEER measurements with an EndOhm. If the resistance readings from your ENDOHM don't stabilize, you may need to do some troubleshooting.

The EVOM™ family of TEER measurement meters have been cited in over 16,000 peer-reviewed, scientific journal articles. The EVOM™ Manual has been designed to improve workflow efficiency, increase stability, and provide more repeatable measurements than older Trans Epithelial Electrical Resistance (TEER) meters including the Millipore MilliCell® ERS-2, Millipore MilliCell ERS and World Precision Instruments EVOM2, EVOM and EVOMX. Here’s a quick summary of benefits of the EVOM™ Manual versus the MilliCell ERS voltohmmeter.

Here are some frequently asked questions (FAQ) about Metal Microelectrodes.
...moreWhat metal type is best for my application?
W- Tungsten
Tungsten is a versatile and widely-used microelectrode material that offers a good balance between performance and cost.
ADVANTAGES
DISADVANTAGES
- Extremely strong and stiff metal provides probes with exceptional rigidity.
- Great for acute and chronic recording due to biocompatibility and lower cost.
- High corrosion resistance offers consistent long-term performance.
- Does not provide the same degree of electrochemical performance or stability as platinum-iridium alloy, making it a poor alternative for microstimulation.
- Lower charge transfer capacity of tungsten will result in larger, potentially unsafe interfacial potentials when applying the same stimulation current as to a platinum-iridium electrode.
- Certain pH or stimulation conditions can lead to tungsten corrosion.
PI- Platinum-Iridium Alloy
Platinum-Iridium alloy is considered by many to be the “gold standard”
