MEDICAL, the ideal choice for plants for the distribution of medical gases and vacuum systems.
The MEDICAL copper tube is manufactured according to the most modern technologies on the current world market, in observance of European standard EN 13348, compatible with equipment manufactured in accordance with the Medical Device Directive 93/42/EEC and the result of scientific studies and tests that guarantee the maximum compatibility for distributing the following gases and systems:
- oxygen, nitrous oxide, nitrogen, helium, carbon dioxide, xenon;
- air for breathing;
- specific mixtures of these gases mentioned above;
- air for operating surgical instruments;
- anaesthetic gases and vapours;
The inner surface meets the requirements of reference standard and is also free from incompatible materials with medical gases.
*The inner surface meets the requirements of reference standard and is also free from incompatible materials with medical gases.
