Material Properties

Autoclaving Guidelines:

Products that are autoclavable (see Physical Properties) should be autoclaved according to the following procedure:

  • Temperature: 121°C
  • Pressure: 15psi
  • Time: 15 minutes
  • Cycle: Steam

* Dry Cycle Not Recommended

Sterilized Products:

Products denoted as sterile are manufactured with radiation grade material to ensure their continued quality after the sterilization process. Radiation grade material better maintains its physical properties and is less likely to discolor. Products are sterilized in accordance with AAMI guidelines by Gamma Irradiation. Certificates are available upon request.
