Control Vessels from Any Vendor

Finesse G3Lab Universal Controllers have been designed to
interchangeably connect to most brands of glass, single-use
or rocker bioreactors without sacrificing the quality of control.
G3Lab Universal Controllers are modular by design, so hardware
configuration can easily evolve with a process, and integrate
even more functionality and third party peripherals as needed.

G3Lab Universal Controllers operate bench top single-use or
re-usable bioreactors (up to 45 L), and rockers (up to 50 L).
The system consists of a utility tower and a TruFlow gas manifold.
G3Lab Universal Controllers minimize footprint while maximizing
process flexibility. By leveraging the same industrial automation
components as the G3Pro, G3Lab systems enable fully traceable
cGMP process scale-up and scale-down in the laboratory
environment. G3Lab controllers are available in both NEMA2
(labscale) and NEMA12 (cGMP) versions.


  • Optimized to control a typical R&D glass,
    disposable stirred or rocker bioreactor
  • Modular, flexible yet affordable
  • Includes auxiliary control loops
    for third party peripherals
  • Powered by Finesse TruBio® software
  • Utilizes Finesse SmartParts components
