he 9mm Blue Screw Bonded Non-Slit Cap Septa features a permanently bonded PTFE/silicone septum without a pre-cut slit, providing an exceptionally tight seal to minimize evaporation and contamination. It is ideal for long-term sample storage and applications requiring maximum sample integrity. Although the initial needle penetration requires slightly more force than pre-slit septa, it offers superior sealing performance for sensitive analytical samples. Key Features - Bonded PTFE/Silicone solid (non-slit) septum - Excellent sealing performance for reduced evaporation - High chemical resistance and sample compatibility - Secure 9mm blue polypropylene screw cap - Suitable for repeated injections while maintaining seal integrity - Ideal for GC and HPLC autosampler vials Usage / Application Areas - Long-term sample storage before analysis - Volatile and evaporation-sensitive analytes - Gas Chromatography (GC) - High Performance Liquid Chromatography (HPLC) - Pharmaceutical and biotechnology laboratories - Environmental and food testing laboratories - Chemical and research laboratories Benefits - Minimizes sample loss due to evaporation - Protects samples from contamination - Provides reliable leak-proof sealing - Improves sample stability during storage and transport - Compatible with standard 9mm screw-thread autosampler vials
