SHT Portable Gas-tight Liquid Sampler

SHT Gas-tight Liquid Sampler

The SHT Gas-tight Liquid Sampler is a closed-system device engineered for safe, contamination-free sampling of liquids — particularly suited for hydrocarbons and corrosive fluids such as those found in oil or chemical tankers. It features a 30 m stainless steel tape with metric markings, along with a zone sampling bottle (0.4 L capacity) and an additional lab bottle (0.5 L). Designed for durability and low maintenance, the sampler includes a cleaning wiper for the reading glass, uses a modular design, and comes with a robust transport case. It weighs about 7.4 kg and measures approximately 180 mm × 160 mm × 900 mm. The device is rated to tolerate a maximum tank overpressure of 0.3 bar.

Working principle:

The sampler is designed as a closed, gas-tight system so that liquids from tanks (oil, chemicals, or other volatile/corrosive fluids) can be collected without contamination or realising harmfull vapors

1. Preparation

   • The operator lowers the sampler into the tank using its stainless steel measuring tape (up to 30 m).

   • The depth is read directly from the metric markings on the tape.

2. Sampling

   • At the desired depth, the zone sampling bottle (0.4 L) collects a liquid sample.

   • Because the system is sealed, gases and vapors are prevented from escaping, and no external contaminants enter.

3. Retrieval

   • The sampler is pulled back up.

   • The sample remains inside the gas-tight bottle, preserving its original properties (composition, temperature, vapor pressure, etc.).

4. Transfer

   • The collected liquid can then be carefully transferred into the provided laboratory bottle (0.5 L) for testing and analysis.

   • Since the system prevents air contact, results are more reliable, especially for volatile or sensitive substances.
