ENDOHM Tissue Resistance Measurement Chambers
· Endohm Chamber with EVOM Voltohmmeter provide reproducible resistanc
measurements of endothelial tissue in culture cups.
· Endohm with EVOM offers a much more convenient and economic solution to
“leaky tissue” measurement.

AUTOMATED TISSUE RESISTANCE MEASURING SYTEM

The REMS AutoSampler automates measurements of electrical
resistance of transepithelial, transendothelial or Caco-2 cell me mbranes
being grown to confluence on microporous filters of high
throughput screening (HTS) 24 well microplates.
Automated measurement of tissue resistance in cell culture microplates
provides the important advantages of speed, precision,
decreased opportunity for contamination and the instant availability
of measured resistance data on a computer. These measurements
are useful in applications such as drug bioavailability studies
and studies on the mechanisms of drug transport.
