User Guide

Working with pressurized reservoirs requires to follow some recommendations to ensure your security.

Recommended pressure range: 0 - 200 mbar (other pressure ranges have not been tested).

Pressure resistance tests have been performed on the pressurized tanks. Protocols and results of the tests are available upon request.

General recommandations

  • Do not use a tube or a bottle that look damaged or has encountered a shock.
  • Use only the same tube references if you need a spare one. We cannot guarantee that other references of tubes or bottles used by the end-user will withstand the same pressure ranges.
  • Make sure that the tube/bottle used with Elveflow pressurized tube cap is adapted to the experimental conditions (chemical compatibility of the material, resistance to temperature, …) to fulfill security requirements.
  • Use security equipment adapted to specific experimental conditions. You may be using pressurized reservoirs containing dangerous liquids and presenting explosion risks (protection glasses, security net or shield). Also, depending on the nature of the liquid, it is the user responsibility to use indicated security equipment (PPE, chemical hood, …).
