24-Channel Reader for Online O2 & pH Monitoring in 6- and 24-Well Plates

SDR SensorDish® Reader Extension Set

Up to 9 SDR Extension Sets can be combined with one Basic Set. The Extension Set consists of a reader and a connection cable to install up to 10 devices in a row. Instead of having to change the plate on the reader monitoring can be carried out in up to 240 samples in parallel. The up to 9 Extension Sets and the Basic Set SDR can be controlled and read out with one software.

  • Optional extension for parallel monitoring of up to 240 samples
  • Parallel online monitoring in disposable 24- or 6-well plates
  • Deep well plates (24-well format) & low well plates available
  • Non-invasive & non-destructive measurement
  • Pre-calibrated
  • For use in incubators and on shakers
