Tandem Off Gas Analyzers | Multi Line and Continuous Systems

The Tandem gas analyzer systems will give you real-time, on-line data that helps you understand and control your cell culture experiments. Specifically designed for CO2 and O2 exhaust gas analysis from cell culture experiments, the tandem range fits onto a wide range of systems, from different manufacturers.

Key Features

– Get deeper understanding of your cell cultures on-line
– With greater control, increase the reliability and repeatability of your process
– Automate your processes and controls, based on real-time feedback
– Flexible design allows the same data to be recovered from all your reactors
