General description

Suba-Seal® silicone rubber septa offer improved chemical resistance compared to natural rubber.
Suba-Seal® silicone rubber septa with turnover flange grips outside of the container neck promote a double seal in conjunction with annular serrations on the hollow plug. The annular serrations of the septa depress themselves against the inside wall of the bottleneck, making each serration a suction sealing point.

Features and Benefits

  • Translucent silicone rubber septa
  • Contains no pigments, waxes, or molding agents
  • Good for high heat applications (200°C continuous or 400°C intermittent)
  • Autoclavable for sterile uses
  • Excellent resistance to deterioration due to sunlight and ozone
