Swagelok^® Grab Sampling Systems

Configurable, Reliable Grab Sampling Panels

Swagelok offers fully configurable, locally built and supported, and reliable grab sampling solutions in a variety of configurations with advanced features intended to help you safely capture representative samples of liquid or gas from your process lines. Whether you want closed-loop sampling into pressure-rated sample cylinders or simply want to collect process fluid into lower-cost glass laboratory bottles for analysis, Swagelok’s sampling panel options that are safe, intuitive, easy to maintain and can be ordered as a single part number. Each sampling system is built with Swagelok^® tube fittings to reduce potential for leaks.

Grab Sample Module

The Swagelok^® grab sample module (GSM) is a closed-looped sampling system that pulls from a positive-pressure process and returns to the process at a lower pressure location (e.g., upstream of a pump) by using differential pressure to drive the fluid through the system. Samples are deposited into durable, pressure-rated metal grab sampling cylinders (GSC) that prevent the sample from escaping, protecting operators.

Interested in Knowing More About Grab Sampling?

• GSM panels feature a switching valve configuration with two or three Swagelok^® 40G series ball valves, allowing for simultaneous control of fluid routing, reducing the number of steps required
• A GSC is docked, and process fluid is continuously circulated within to maintain process conditions
• A GSC is required for every GSM system and should be ordered separately when purchasing a new GSM
• The GSM can be left in the bypass or sample position indefinitely, keeping transport lines fresh and ready for sample capture
• A rupture disc is an available option for every GSM system, and a relief valve can also be added to sampling systems where there is added overpressure concern

Grab Sample Liquid Systems

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.

Improve the Safety and Efficiency of Liquid Sampling

• Fixed-volume Swagelok GSL systems use the same switching valve as a GSM system to provide simplified operation for complex tasks
• The GSL can use lower-cost glass or polyethylene laboratory bottles to draw and store samples
• Samples can be drawn and transported without the risk of spillage or evaporation
• A spring-return handle on the sample drawing mechanism prevents unintentional dispensing

Ammonia Sampling

The Swagelok^® ammonia sampler makes anhydrous ammonia sampling safer by minimizing operators’ exposure to liquid and vaporized ammonia. It also introduces consistency into the sampling operation significantly expedites the sampling process and eliminates the transportation of ammonia samples within the facility.

Grab Sampling Valve

Overcome the safety, maintenance, and quality challenges associated with standard bottle sampling by adding a Swagelok^® grab sampling valve to your fluid system. The leak-free design eliminates rubber O-rings by using a Swagelok^® tube fitting to attach the needle assembly to the valve body.

Simply tighten the tube fitting nut to create two all-metal seals. A pencil point needle assembly pierces without coring the septum, minimizing clogged needles and leaking sample bottles. When the Swagelok grab sampling valve is specified with a spring return handle, the valve automatically moves to the closed position when the handle is released, ensuring you collect the sample amount that you need.

Accessible Grab Sampling Support

When you decide to invest in Swagelok^® grab sampling panels to bring standardization and reliability to your sampling operations, your local authorized Swagelok sales and service center team will work with you to determine the right type of panel and the proper configuration to meet your needs. A certified Swagelok engineer will review your information and recommend the right panel for you.

Finally, we provide hands-on training on grab sampling system use and maintenance for your technicians once your panels are assembled.
