LABORATORY & RESEARCH CENTERS GAS EQUIPMENT

Precision and Purity: Specialty Gases Driving Laboratory Success

  • Specialty gases play an important role in the research sector, creating controlled environments for high-precision scientific experiments.
  • Specialty gases can be used to calibrate gas detectors and other measuring equipment to ensure they are working properly.
  • Certain other applications, such as chromatography, may require the use of specialty gases.
  • Many other applications requiring high levels of precision and safety make use of specialty gases.

Rotarex products meet the highest standards

  • Safe, reliable distribution system to avoid any accidents linked to potential leaks.
  • Accurate gas flow is also fundamental for many specialty gas applications, to guarantee quality results.
  • Gas distribution installations need to be compact enough to minimize the space used in laboratories for example.
  • All this gas equipment is used by many people, so it has to be easy to use.
  • Rotarex offers a complete range of products for the distribution of specialty gases.
