We offer 2 categories of grab sample systems:


Grab Sample Modules (GSM) using cylinders


Liquid-Only Systems (GSL) using bottles

The Swagelok® grab sample module (GSM) is a closed-looped sampling system that pulls from a positive-pressure process and returns back to the process at a lower pressure location. The Swagelok® grab sample liquid (GSL) is a liquid-only sampling system for drawing fluid into a non-pressure-containing bottle with a self-sealing septum cap in applications where the process fluid is not at risk of fractionating when stored at atmospheric pressure. All Swagelok grab sampling systems are designed to protect both your personnel and your profitability, and each panel is configured to meet your specifications.

Regardless of which type you need, Swagelok will provide you with accurate, safe grab sample systems customized to your specifications and completed with a turnaround to fit your schedule. We work with you to assess your current system, recommend a panel that meets your needs, customize our standard panel to your specifications, assemble and test the system, and train your technicians once the panel is assembled. The right local support by sampling system specialists can provide immense value to your organization.
