一般說明

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.

特點和優勢

  • 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

Questions

1–3 of 3 Questions  

  1. can this septa be used with aggressive chemicals like Thionyl Chloride - some of this reagent may get into contact with the septa, would it degrade as a result of a brief contact at room temperature?

    1 answer

    1. There have not been any specific tests regarding the use of this silicone rubber septa with thionyl chloride. There is general information regarding chemical compatibility from online resistance guides for thionyl chloride that indicates this compound is recommended for use with "fluoroelastomers." Please see this chemical compatibility information at the link below.

  2. Can the Suba-Seal silicone rubber septa be sterilized with gamma irradiation?

    1 answer

    1. Our silicone suba seals are generally steam sterilized. Testing has not been done here at Sigma-Aldrich using gamma irradiation. Gamma rays are known to change some physical properties of silicone rubber. Refer to the attached white paper from a leading manufacturer of silicone rubber products. Based on this, it seems gamma irradiation is detrimental to silicone rubber.
