Septa Vial Sealing Materials
Tac-Sep Septa liner materials are designed for proper sealing of medicinal vials and other devices to prevent contamination.
Tac-Sep is a two-layer composite consisting of silicone elastomer and PTFE film. When installed inside a metal or plastic cap, a syringe needle can pierce the rubber septum and pull a substance from the vial for the purpose of injection. Upon withdrawal of the syringe needle, the elasticity of the silicone septum ensures that the hole reseals.
The quality of the barrier film and rubber is a critical factor in vial sealing applications. Poor quality materials can cause improper re-sealing, skewed test results, and yield poor quality products.
Features:
• Excellent resealability • High PTFE/Silicone rubber bond strength • Temperature resistant from -40 - 200 °C (-40 - 392 °F) • Excellent chemical resistance • Uniform hardness of silicone rubber
Applications:
• Vial sealing in pharmaceutical and life science industries
• Chromatography research (gas chromatograph & mass spectrometer experiments
