EVOM™ Auto, with both 24 and 96 HTS multiwell plate capability, is a high throughput screening (HTS) platform offering fast, noninvasive sample scanning by comparing electrical resistance measurements (transepithelial/transendothelial electrical resistance: TEER). TEER measurement experiments are simple to set up and less time consuming than more complex molecular studies. TEER measurement can be used as the primary scanning method to identify any physiological changes that can then be further evaluated by other methods. EVOM™ Auto can capture TEER measurements in 24 and 96 HTS multiwell plates from Corning, Millipore, or MatTek. The sample preparation time in these HTS plates is efficient, allowing for fast, multi-channel pipetting options.
The EVOM™ Auto autosampler ships with a red electrode array lock in place to prevent the electrode array connection port from moving during transit. Here you can see how to easily remove it without damaging the lock or the autosampler...more

If the EVOM™ Auto software switches from Resistance to TEER mode while you are selecting menu options, here's a quick tip:
Be careful when selecting Resistance mode, do not tap the background window and do not click on the side arrows.
Tapping the background window will switch you to TEER mode.
Instead, tap an option on the forefront square window to stay in Resistance mode...more

On the new WPI website, multiple related products may be grouped together to make them easier to compare.
The price range of all the options is shown at the top left corner of the product page.
To make a selection easier, a grid in the Details area (below the images) lists the details of all the products listed on the page, including the order code.
Click Choose an Option to select the model you want. If the option price deviates from the default selection, you see the additional cost listed next to the option. In this example in the video, the curved scissors cost $4 more than the straight, and the German steel scissors cost $43 more.
When you select your option, the price of your selection shows at the top of the screen.
Select the quantity you need and click the Add to Cart button. The shopping cart reflects the price of your option.

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.
