1) Description
The high-quality green 9-425 open top ribbed screw cap, equipped with PTFE/Silicone septa , is a closed system specially designed for high-precision laboratory analysis. This unique combination is designed to provide optimal sealing performance and chemical inertness for a variety of scientific research, chemical analysis and storage of biological samples. The green closures are easy to identify, while the double-layer structure of PTFE and Silicone ensures the safety and integrity of the sample.
2) Application
HPLC and GC Autosampler Analysis
Open top caps are used where high-throughput sample analysis via an autosampler is required. This design allows the sampler needle of the autosampler to pass directly through the opening in the cap to extract the sample in the bottle without manually opening the vial cap, improving the efficiency and accuracy of analysis. For laboratories that conduct a large number of sample tests, the use of open top caps with automatic samplers can significantly improve the speed and repeatability of sample processing and reduce human errors during operation.
3)Features
▶ High-quality Materials: Use chemically resistant PTFE and flexible silicone materials to ensure compatibility with various chemical substances and prevent sample contamination.
▶ Excellent Sealing Performance: The green 9-425 open top closures, with ribbed design, provide extra grip to ensure the lid is easy to tighten and open while maintaining an excellent seal.
▶ Double-layer Septa Design: The PTFE and silicone Septa combine the chemical stability of PTFE with the excellent sealing and elasticity of silicone to provide double protection for the sample.
▶ Easy to Identify: The design of green caps and septa in various color combinations facilitates laboratory management and quick identification, improving work efficiency.
▶ Wide Compatibility: suitable for most 9-425 screw-top vials to meet the needs of different laboratory applications.
