Characterization

The biocompatibility of STHT® platinum-cured silicone hose, manufactured with Sani-Tech® silicone,has been tested and complies with the parameters set forth in the following test protocols:

  • USP XXIV (88) biological reactivity, in vivo
    - Intracutaneous test, Systemic injection test, Implantation test
  • USP XXIV (87) biological reactivity, in vitro
    - L929 MEM elution, AGAR diffusion
  • ISO 10993
  • FDA CFR 177.2600
  • Meets or exceeds USDA standard and 3A approval
  • European Pharmacopoeia 3.1.9
Sterilization Methods
  • Autoclavable
  • Radiation – up to 5.0 Mrad (50 Kilogray)
  • Gas – Ethylene Oxide

NOTE: STHT® hose will not deteriorate with repeated autoclaving. This method of sterilization is strongly recommended. STHT® silicones should not be considered for consistent steam applications.

WARNING: Do not use STHT® silicone hose in hot oil or acid applications.
