White 8-425 Open Top Screw Closures

1) Description

These closures are specially designed for the 2ml 8-425 autosampler vial and have a built-in PTFE/SILICONE septat. It is an ideal choice for precise laboratory analysis. Made of high-quality materials, it has excellent chemical stability and excellent sealing properties, effectively preventing sample contamination and volatilization, and ensuring the accuracy of experimental results. It is suitable for widespread use in high-performance liquid chromatography (HPLC), gas chromatography (GC) and other analytical tests, and meets the laboratory’s high standard requirements for sample processing. Easy to operate and highly adaptable, it provides great convenience and reliability guarantee for scientific research and quality inspection work.

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.
