Defined, continuous, online real-time CO2 analysis often is the key to success in modern bioprocessing. The BCP-CO2 gas analyzer can be applied in every scale starting from shake flasks or anaerobic digesters in the lab up to industrial scales. The BCP-CO2 allows you to scale up your process using the same technology at every scale step minimizing variations and unpredictabilities due to changes in measuring technology at the different scales. The BCP-CO2 gas analyzer is easy to connect directly to the exhaust flow of all types of fermenters and bioreactors (stainless steel, single-use or glass). In combination with a bioprocess software (such as BlueVis) the BCP-CO2 can be used to calculate essential respiration parameters as CER (carbon dioxide emission rate) and RQ (respiratory quotient). All BCP-analyzers are available with aluminium (pilot to industrial scale use) or PA (lab scale) casings.

BCP-CO2 – non-invasive measurement independent from flow and scale  

  • in-situ gas analysis ➔ non-invasive measurement directly where it happens
  • flow and scale independent ➔ one type of analyzer (technology) type for all scales ➔ less variations and unpredictable influences
  • direct integration in gas pipelines behind the sterile barrier ➔ calibrate your analyzer at any time without the risk of contamination
  • pressure and temperature compensated automatically leading to high accuracy and process reliability
  • universal mounting opportunities for convenient integration on new or existing equipment
  • standardized data interfaces for simple connection to any process lead system (PLS)

Application areas

  • pharmaceutical industry
  • biogas plants
  • any type of fermentation processes
  • laboratory scale
  • large industrial plants
  • (parallel) bioreactors
  • connection to disposables available

BlueVary – for 100% flexibility

BlueVary is a maintenance free gas analyzer for variable applications. By freely selectable sensor cartridges different measuring tasks can be covered by just one device.

BlueVary consists of a basis element with measurement places for two of the variable gas sensor cartridges. That way two gases can be measured in parallel. The third place holds a sensor cartridge for pressure and/or humidity. An integrated display ensures insight of the measured data at any time. Various mechanical connections make BlueVary fit on every fermenter. Numerous data output possibilities are available. Annual maintenance is unnecessary. To maintain accuracy of the readings a one-point calibration has to be performed (by the user) in reasonable time intervals.
