COBRA Sampling

Ideal for use in the following industries:

• Chemical
• Petrochemical
• Refineries
• Specialty
• Natural Gas

Industrial processes have grown in complexity over the years, and the need to maintain processing quality means there is an essential need for fully reliable testing and analysis techniques.

Cobra Sampling was established to address this need, and we have made it our business to ensure our range of closed loop gas and liquid samplers not only meet industry expectations, but surpass them.

Located in Houston, Texas, Cobra Sampling, Inc. is dedicated to developing the most effective and most efficient gas and liquid samplers available. Working closely with our customers, whether national, international or locally-based in Texas, sampling is made simpler and safer through designs that ensure emissions-free sampling that protects the operator as well as the environment.

Our sampler design and manufacturing companies are amongst the best in the world, and Cobra Sampling, Inc. has quickly established itself as one of the leading lights in the field. Our reputation is based on consistency in reliability and flexibility in design, ensuring our clients are 100% satisfied every time and can have 100% confidence in their Cobra-designed gas or liquid sampler.

Cobra M (Manual Liquid Sample System)

Designed for longevity, the Cobra M liquid sampler boasts a variety of unique features that makes it simpler to install and more convenient to use. Made of stainless steel and other exotic materials, the sampler meets the highest standards of quality and reliability. All of our Cobra M units use the Cobra-designed FLO-THRU sampling valve to facilitate easy regulation. The system also provides ample time for air and other gases to be expelled, ‘clean’ samples are assured.

The Cobra M includes a multi-turn handle that permits precise flow control, while a full bore flow path ensures that no pressure is lost while the sample is being extracted. And because standard units come with our special patent pending coaxial needle system, the risk of bent or broken needles is reduced dramatically. Also, our FLO-THRU sampling valve has been specifically designed for process sampling, and protects against contamination to ensure the integrity of every sample taken.

Key features include:h

• Special patent pending coaxial needle system prevents bent and broken needles
• Multi-turn handle for throttling and precise control of flow
• Hardened seat for severe applications
• ½” full bore flow path with zero pressure drop
• Zero dead volume through valve body with optional purge
• Rugged handle and stem for longer cycle life
• True sampling valve designed specifically for process sampling

Designed for the following applications:

• Liquid Samples with low vapor pressure
• High VOC chemicals

Cobra C (Cylinder Sample System)


The Cobra C gas and liquid sampler makes the task of collecting representative samples from gas and light liquid hydrocarbon applications simpler and safer. Designed with safety for both the operator and environment in mind, the Cobra C offers a low-maintenance solution to sampling requirements. It also offers emissions-free sampling, with no spills and zero VOC emissions, keeping both pollution and sample contamination levels to an absolute minimum. It’s ideally suited to use in the petrochemical, refinery and natural gas industries.

The Cobra C uses a multi-ported valve so that the extraction process is reduced to the minimum while maintaining the integrity of the sample itself. Installation is fast and straightforward, with quick disconnects ensuring the sample cylinder can be removed with no tools required. The Cobra C is fully LDAR and MACT compliant, while a DOT rated stainless steel cylinder ensures quality, reliability and longevity.
