    The CultiBag RM is a single use bioreactor bag available in multiple sizes and configurations depending on customer requirements. The inner layer of the disposable bioreactor bag is made of ethyl vinyl acetate (EVA), which shows an excellent biocompatibility.

    Precise and reliable single-use sensors for pH and DO come pre-installed and sterilized with the bag. The sensors are pre-calibrated and the calibration data is supplied together with the bag. After entering the data in the controller, the sensors are ready foruse. Calibration is fast and convenient. An optical fibre connects to the sensor patch, which is located at end of a sleeve in the bag. As there is no physical contact of the optical fiber to the inside of the bag, sterility is maintained at all times. The optical fibre transmits light of specific wavelengths to the sensor patch and returns the luminescence response from the sensor back to the measuring amplifier.

    Flexibility and Configurations
    The CultiBag RM is available in 1 L, 2 L, 10 L, 20 L, 50 L, 100 L, 200 L and 600 L bag sizes. Bags are available as basic, optical and perfusion pro configurations. Basic bags are designed for use in seed train and production applications without pH and DO control. Optical bags feature single use optochemical pH and DO sensor, which are already installed in everybag and calibrated. Used together with the BIOSTAT™ RM control tower, they allow high end cultivation with full process automation.
