HERMetic Sampler GTX Chem – Portable Gas-Tight Chemical & Liquid Sampling System
HERMetic Sampler GTX Chem is a precision-engineered portable gas-tight sampling system designed for safe and representative closed sampling of chemicals and liquids in terminal, refinery, marine, and industrial tank applications. Developed for applications where no gas release is permitted during sampling, the HERMetic Sampler GTX Chem provides a controlled method of collecting liquid samples while helping prevent pressure release from the tank and exposure to fumes.
The system is specifically designed for chemicals and liquids presenting fire, health, or air-pollution hazards, including applications involving corrosive and non-corrosive liquids with low or high viscosity. The sampler can be fitted with different sampling bottles to obtain spot, bottom, running, or zone samples, providing flexibility for representative tank-content sampling.
The HERMetic Sampler GTX Chem is compatible with 2-inch HERMetic Compact Valves and uses a quick-connect coupling for installation. Its robust construction incorporates AISI 316 stainless steel, PTFE, and PVDF, with FFKM gasket material for applications involving corrosive liquids.
Core Working Principle
The HERMetic Sampler GTX Chem operates through a closed, gas-tight sampling connection installed on the tank. The sampler is connected to a suitable 2-inch HERMetic Compact Valve using the quick-connect coupling, allowing the sampling operation to be performed without opening the tank directly to the atmosphere.
The appropriate sampling bottle is lowered to the required sampling position using the graduated measuring tape. Depending on the selected bottle and sampling procedure, the system can obtain spot, bottom, running, or zone samples from the tank.
After the liquid sample has been collected, the sample is transferred from the sampling bottle into a laboratory bottle. For the GTX Chem configuration, this transfer is performed by over-pressurizing the upper chamber of the sampler using the integrated pump. Opening the transfer valve and actuating the pressure pump moves the collected liquid into the laboratory bottle for further analysis.
The gas-tight construction helps prevent tank pressure release and operator exposure to potentially hazardous fumes during sampling. The graduated tape also enables operators to check and record the sampling bottle height, supporting accurate sampling from the required tank level.

HERMetic Sampler GTX Chem: Advanced Gas-Tight Chemical & Liquid Sampling
The HERMetic Sampler GTX Chem is a professional portable gas-tight sampling system designed for closed sampling of chemicals and liquids where release of vapours or exposure to the tank contents must be minimized. The system is particularly suitable for terminal, refinery, marine, and industrial applications involving liquids that present fire, health, or air-pollution hazards.
By combining a portable sampling assembly, graduated measuring tape, sampling bottle, transfer system, and gas-tight tank connection, the GTX Chem provides operators with a practical solution for collecting representative liquid samples while maintaining controlled sampling conditions.
The system is particularly suitable when a representative sample of tank contents is required and when sampling must be performed without releasing tank gases to the surrounding environment. It can be used for liquids with low or high viscosity, as well as corrosive and non-corrosive products.
The HERMetic Sampler GTX Chem is designed for use with 2-inch HERMetic Compact Valves and incorporates a quick-connect coupling that simplifies installation and removal. The system can also accommodate adapters for other compatible valve arrangements.
Different sampling bottles can be fitted according to the required sampling procedure. This allows operators to obtain spot, bottom, running, or zone samples, depending on the tank measurement and sampling requirements.
The sampler has a sampling bottle capacity of approximately 0.47 litres (16 oz), providing a suitable sample volume for subsequent laboratory analysis. The graduated 30 m / 100 ft tape allows the sampling height to be checked during the operation.
After the required sample has been collected, the liquid is transferred from the sampling bottle into a laboratory bottle. Unlike the GTN Chem configuration, where the sample can be transferred while maintaining closed conditions, the GTX Chem uses an upper-chamber pressure pump to transfer the liquid after opening the transfer valve. This distinction is important when selecting the appropriate HERMetic sampler for a particular application.
The instrument is constructed using AISI 316 stainless steel, PTFE, and PVDF, providing a robust material combination for demanding liquid-sampling applications. The GTX Chem uses FFKM gasket material, making it suitable for applications involving corrosive liquids.
The gas-tight construction helps prevent pressure release from the tank and exposure to fumes during operation. This makes the sampler particularly valuable when the sampled liquid may present a fire, health, or air-pollution hazard.
The HERMetic Sampler GTX Chem is designed and certified for use in potentially explosive areas, with ATEX II 1 G c IIB T6 approval. Honeywell also states that the unit is approved by major classification societies and complies with applicable requirements including API MPMS Chapter 17.11.
The HERMetic Sampler GTX Chem provides a dependable combination of gas-tight tank connection, representative liquid sampling, adjustable sampling position, controlled sample transfer, and chemical-compatible construction, making it a practical solution for professional closed sampling applications in marine, terminal, refinery, and chemical industries.
