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

The WPSS01 skin stapler is an affordable, reliable solution for veterinary wound closures. A skin stapler is designed for the efficient closure of surgical incisions or wounds by applying surgical staples to the skin, reducing surgery time and time under anesthesia. Each disposable skin staple cassette contains at least thirty-five (35) 316L stainless steel staples.
Each reusable skin stapler handle is provided sterile with one disposable staple cassette already loaded into the handle. Discard the disposable staple cassette after the procedure. The reusable handle may be cleaned and resterilized (autoclave, EO) for subsequent procedures and will effectively deploy at least twenty (20) disposable staple cassettes and withstand at least twenty (20) autoclave cycles...more
