Wanted: Safe solution with local assembly

As more industries bring additional analytical equipment online, it becomes more imperative to have quality sample systems that can accurately capture the process for later analysis. Swagelok understands the complex need to have a reliable grab sample system that can be available across multiple sites and between site locations and still support specific application needs. As an industry expert with years of sampling expertise, it was fitting for the company to introduce a safe solution capable of being locally assembled.

Configurable. Local. Reliable.

Swagelok grab sampling systems satisfy gas and liquid non-slurry sampling service in a consistent, reliable package. 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).

Selecting system type & sample container

The selection process is aided by the actual limitations of the sample containers themselves. 

  • Sample Cylinder – the GSM system is for samples with a vapor pressure above 14.7 PSIa (1.01 Bara) at ambient conditions.
  • Bottle Sampling – the GSL system for samples with a maximum vapor pressure of 14.7 PSIa (1.01 Bara) at ambient conditions.

Swagelok has developed a number of standard grab sample panel designs for use in all types of plants and facilities where fluids are being processed. We work with you to determine which of these panel designs will best suit your sample system needs.
