29 Surgical Instruments with display case and flash cards
Learning to identify the instruments is made easier when students can handle each instrument and compare action, weight, and feel.
EVOM2The EVOM was the first instrument designed specifically to perform routine TEER (Trans Epithelial Electric Resistance) measurement in tissue culture research. Please note that the legacy EVOM and EVOMX were replaced by the updated EVOM2 in 2008. Features of the EVOM2 include:
One unique feature of the EVOM² is that resistance readings are unaffected by membrane capacitance and membrane voltage. The membrane voltage reading range is ±200 mV. EVOM² comes complete with the popular STX2 "Chopstick" electrode set. The STX2 consists of a fixed pair of double electrodes, 4mm wide and 1mm thick. Each stick of the electrode pair contains a silver/silver-chloride pellet for measuring voltage and a silver electrode for passing current. The small size of each electrode is designed to facilitate placement of the electrodes into cell culture wells. STX2 can be used with all tissue culture inserts currently on the market. For higher accuracy measurements or lower resistance epithelia, the EVOM² can be used in conjunction with the optional Endohm chambers.
