Gas management - 2Mix

2Mix device controls the flow of gases

2Mix with 4 gas linesThe 2Mix is consist of two (default) or more gas lines (designated A, B...), with individual inputs on front side, and outputs on backside. Each line can separately control a flow of a desired gas or gas mixture, and the outputs can be joined together to form new mixtures.

The mixing ratio is dynamic and can be predefnined from the software.

The device can therefore act as easy and convenient way to control large number of individual gas flows, as well as a platform to perform variable partial pressure ramps and steps, total flow ramps, or any combination of such.

The default device has flow ranges:

  1. A: 0.005 ml to 50 ml/min
  2. B: 0.05 to 500 ml/min

But the flow range for each line can be freely adjust at the time of order where lowest possible range is 0.000 05 ml/min to 0.5 ml/min with no practical upper limit other than for ranges above 0.025 liter/min to 250 liter/min the size, weight and price will increase progressively.
