3) 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.
