Grab Sampling Systems

Configurable, Local, Reliable Grab Sampling Assemblies

Our standard grab sampling panels are fully configurable, locally built and supported.  Our panels reliably and safely capture accurate, representative process samples that maintain their chemical composition during storage and transport for later analysis.  Our panels are available in a variety of configurations and have advanced features that maximize operator safety, ease of use, and uptime. Plus, local support ensures fast, dependable expert service.

• Designed and built with the reliable components you trust from Swagelok

• Local, factory-certified experts for local fabrication and support

• Versatile mounting options for easier installation

• Standard sample systems can be configured using a part number table for simplified ordering

• Additional instrumentation is available, including gauges, meters, and flow indicators

• Backed by the Swagelok Limited Lifetime Warranty

• On-site commissioning certification available after installation

We offer two categories of grab sampling systems:

Two system types allow for capture into one of two types of containers: pressure containing metal cylinders as found in the Grab Sample Module (GSM) or non-pressure containing glass or polyethylene bottles as found in the Liquid Only Sampling Module (GSL). 


The Grab Sample Module (GSM) is a sampling panel that uses sealed, metal, pressure-containing cylinders to capture either liquid or gas.  This closed-loop sampling system uses differential pressure to drive fluid through the sampling system, ensuring fluid is fresh and ready for sample capture. 

The Grab Sample Liquid (GSL) is a liquid-only sampling system for drawing fluid into a non-pressure containing laboratory bottle with a self-sealing septum cap in applications where the process fluid is not at risk of fractionating or evaporating when stored at atmospheric pressure.
