Gas & Vapor Dosing Systems

FlexiDOSE instruments are universal gas and vapor dosing devices and pressure controllers: Modular design, flexible and customizable high pressure gas and vapor dosing systems.

FlexiDOSE - gas & vapor mixing and pressure controller. The FlexiDOSE instruments can mix gases and/or vapors with exactly controlled compositions. Different models are available for mixing bulk components - typically  in the % concentration range - up to exact control of trace components in the ppm level. These mixtures can be used for instance for calibration of composition measuring instruments or for studying reaction in mixed atmospheres. FlexiDOSE are equipped with highly accurate pressure controllers for preparing the reaction atmospheres in a wide pressure range up to 700 bar.

With intiutive operation through touchscreen control and the integrated hard- and software safety features the FlexiDOSE are ideal for combination with all kinds of reactors, auto leaves and instruments.

Typical features are:

  • Gas dosing and mixing
  • Vapor generation and metering
  • Pressure control

The FlexiDOSE instruments are fully automatic operated by PC control. Its standard gas connections (Swagelok®) allow easy combination and integration with existing autoclaves or reactors.

Typical applications are:

  • High pressure reactions
  • Autoclave operations
  • Gas storage
  • Furnace reaction gas dosing
  • Supercritical fluid extraction
  • Membrane permeability measurements
  • Solubility
  • Catalyst testing

The FlexiDOSE systems can generate static or flowing atmospheres with gases and/or vapors. Basic setup is a gas dosing system (G) available in a pressure range from vacuum to 700 bar.

Models are:

  • Low pressure range (LP): vacuum up to 1 bar
  • Medium pressure range (MP): vacuum up to 50 bar
  • High pressure range (HP): vacuum up to 150 bar
  • Ultra high pressure range (HPII): vacuum up to 350 bar
  • Highest pressure range (HPIII): vacuum up to 700 bar

If dosing of vapor is necessary the gas dosing system can be combined with a vapor dosing device (V). If quantitative gas mixing and dosing is desired it can be combined with a volumetric gas mixing device (MIX).

The FlexiDOSE instruments are designed for operation with our Magnetic Suspension Balance to feed it with gases and/or vapors. Both devices together form a strong and flexible scientific measuring system.

An example of a typical high pressure sorption instrument for gases and vapors in the pressure range up to 150 bar could be our IsoSORP® series of the Magnetic Suspension Balance and a FlexiDOSE Flow system for gases and vapors.

The name of the system would be

IsoSOPR Flow (G&V-HP)
