HERMetic Sampler GTX Chem
for Marine Applications
The HERMetic Sampler GTX Chem is a portable gas tight sampler dedicated to applications where closed sampling of chemicals or liquids is required, and a sample of approximately 0.5 litre of liquid is needed. A sampler with special FFKM gaskets is recommended for operations involving refined products or corrosive chemicals.
What Is It?
The HERMetic Sampler GTX Chem is a portable gas tight sampler for closed operation with liquid transfer. The transfer of the liquid from the sampling bottle to a laboratory bottle occurs by overpressurizing the upper chamber of the sampler with a pump — ensuring zero atmospheric contact throughout the process.
It is the ideal solution in the following cases:
- For applications involving chemicals with low or high viscosity
- When a representative sample of the tank content is required
- When no gas release is permitted during the sampling operation
- When a differentiated type of sample is required (spot, bottom, running, zone)
- When 2-inch HERMetic compact valves are installed on the vessel
The gas tight construction avoids pressure release from the tank and exposure to fumes during operation. The equipment is designed and certified for use in potentially explosive areas (Zone 0).
What Problems Does It Solve?
The HERMetic Sampler GTX Chem ensures safety by preventing exposure to potential fire, health and air pollution hazards, and guarantees a representative sample of the content inside the tank for further laboratory analysis. Users benefit from significantly lower operation and maintenance costs compared to open sampling methods.
- Eliminates operator exposure to toxic, flammable or corrosive vapors
- Maintains full sample integrity — no atmospheric contamination
- Complies with MARPOL and IMO requirements for zero-emission operations
- Suitable for the most demanding chemical tanker cargoes
- Reduces health and safety risk for deck crews during cargo sampling
