Cell Culture Tubes with Integrated pH Sensors

iTube pH

The iTube pH consists of a plastic tube with integrated and pre-calibrated pH sensor spots. They are read out by the SFR Shake Flask Reader or SFR vario in combination with the specially designed iTube adapters. A small plastic adapter piece on the tube bottom allows correct positioning of the tube on the SFR / SFR vario.
