BioLector XT
GET MO2RE DATA. NOW. With or without O2
The BioLector XT high-throughput microbioreactor enables real-time evaluation of biomass, pH, dissolved oxygen in the liquid phase (DO), fluorescence and other key cultivation parameters for aerobes and anaerobes— to quickly provide deep insights into your bioprocess development.
Building on trusted BioLector Pro technology, the BioLector XT microbioreactor is based on a standard ANSI/SLAS (SBS) microtiter plate (MTP) format, and operates with non-invasive, pre-calibrated optical sensors.
Disposable 48-well MTPs enable online measurement of key cultivation parameters while an optional microfluidic module supports simultaneous, well-individual pH control and feeding.
This patented microfluidic technology eliminates manual liquid handling—no tubing/pipetting required, as everything is part of the gamma-radiated ready-to-use plate.
