The A6093 Product Family

The A6093 product family comprises different products, the core tubing consists of a platinum-cured extruded silicon: 

  • A6093 platinum-cured silicon tubing without reinforcement
  •  AE6093 platinum-cured silicon tubing with reinforcement (fabric)
  • AES6093 platinum-cured silicon tubing with reinforcement (fabric) for RE-LINK SI 

These especially – intended for pharmaceutical/biotechnological uses – developed products consist of a specific material (60 Shore base material) and are produced according to a special production process that is established upon detailed quality agreements with the manufacturer.

Toxicological Assessment

 All detected extractable substances have been reviewed by toxicological experts (DGPT/Eurotox Registered Toxicologists (ERT)). They have been assessed to be of no toxicological concern and to do not present a health risk to the patients.

Regulatory Support File

As a special service, we have summarized all results in a very comprehensive “Regulatory Support File of the A6093 Silicon Tubing Product Family”. It is available upon request.

All silicon tubing from TECNO PLAST is also free from animal-derived materials and meet the requirements of the TSE Guideline EMA/410/01 of the European Union.

In conclusion, we can provide you specific customized solutions for all applications.

  •  Standard packaging of A6093 platinum-cured silicon tubing: Tubing coil fixture: A6093 silicon tubing
  • Non-perforated PR bags (pharma quality – EP 3.1.3)
  • Not imprinted or imprinted with white ink (standard) – ink is free from benzophenone!
  • Laser-engraving is under devolpment.

All types correspond to DIN EN 16821:2017-10
