MINI-4-GAS station: Automatic gas-mixing module

What is it about?

The MINIFOR bioreactor and fermentor system is used for growing and testing bacteria, yeast, fungi, mammalian cells and stem cells.

MINI-4-GAS is a module for MINIFOR that allows a completely automatic gas-mix.

The MINI-4-GAS consists of MASSFLOWs and PC-Software.

MASSFLOWS will be measuring and regulating the gas-flow of the desired gasses.

It could be controlled remotely using LAMBDA SIAM PC control software extension.

The LAMBDA gas-mixing module allows a flexible mass flow controlled supply of different gases with individual gas flow paths.
The gassing system automatically mixes up to 4 gases for mammalian cell systems as well as microbial applications at bench scale.
The automatically controlled aeration system provides an advanced gas diffusion by sparging and / or headspace gassing.
The extension 
of LAMBDA SIAM PC control software allows a complete automatic gas-mix control for up to 4 MINIFOR parallel-reactors (4 x 4 gas flow controller)

Build now your own automatic gas-mixing module!

MINI-4-GAS is as easy to interlock as plastic bricks:

The bricks of MINI-4-GAS are LAMBDA MASSFLOWS. Each MASSFLOW will control one gas in your gas-mixture. You can choose two, three or four gases for your gas-mix.

The MASSFLOWS will dose and measure the gas flow rates accoring your set-points (flow rate / pH / pO2 / pCO2…)

The MINI-4-GAS software (a SIAM extension) is the brain of the gas-mix. The PC-software controls, visualizes and saves all gas-flow data.

The MINIFOR bioreactor dissolve the gases by micro-sparger, surface-aeration and excellent stirring with FISH-TAIL – a most efficient gas-uptake under minimized shearing forces.

LAMBDA ADVANTAGES

  • Maintains optimal physiologic culture conditions
  • Optimized process efficiency
  • Retain reproducible production
  • Preclude limiting conditions
  • Cell line stability
  • Prevent inducing physical & chemical stress
  • Increase titer / product yield
  • Satisfy the cells requirement
  • Grow high-density cultures
  • Optimized substrate conversion

Compared to most bio-transformations with quick growing yeast or bacteria, mammalian cell cultures by their low specific growth rates have to be cultured for weeks or even months for satisfying the product yields.

MINIFOR bioreactor offers you the “Lambda Easy Sterility” concept and an excellent peristaltic pumps specially  constructed for the long-term cell cultures. The MINIFOR with the 4-gas-mixing-module maintains the optimal physiologic conditions for your mammalian cells and the stem cell cultures using the  modern control strategies.

Controlling the critical process parameters will help you to optimize the growth rates as well as to achieve the higher titres during protein processing and hormone production.
