4) Applications

HPLC & GC Autosampler Analysis

Open-top caps are designed for high-throughput automatic sample testing. The structure allows autosampler needles to pierce the septum directly for sample extraction without manual cap removal, greatly boosting testing efficiency and data accuracy.

For labs running high-volume sample batches, matching open-top caps with autosamplers dramatically improves sample processing speed and testing repeatability, while minimizing human operational errors.
