Sampling Systems

Collect samples from industrial processes for analysis

Sampling systems, or samplers, enable safe and representative sample collection from industrial processes for analysis. Due to the growing complexity of the industrial processes, the requirements for sample analysis increase continuously, and the safety for sampling process is given more and more consideration. The simple and primitive sampling system has evolved into a safe and reliable closed-loop sampling system. FITOK offers two types of closed-loop sampling systems, namely bottle configuration sampling systems and cylinder configuration sampling systems according to the difference of container. For bottle configuration sampling systems, the sample is drawn into the sample bottle at atmospheric pressure. For cylinder configuration sampling systems, however, the sample is drawn into the sample cylinder at process pressure.

  • Bottle Configuration Sampling Systems for Liquids, BL Series

    BL Series Bottle Configuration Sampling Systems for Liquids are designed for representative sampling of corrosive or hazardous liquids. They introduce the sample into the sample bottle via an inlet needle while expelling air/vapor through a vent needle, ensuring efficient contamination-free collection. Available in multiple configurations (e.g., purge and heating/cooling types) to meet diverse operational needs. With easy and safe operation, the BL Series is widely used in petrochemical, pharmaceutical, and chemical industries.

  • Cylinder Configuration Sampling Systems for Liquefied Gases, CS Series

    CS Series Cylinder Configuration Sampling Systems for Liquefied Gases are designed for sampling liquefied gases or high-vapor-pressure liquids under high pressure or hazardous conditions.  The expansion chamber design prevents overfilling, ensuring a safe sampling process. Configurations include expansion chamber purge type, bypass purge type, and vent to flare type, catering to varied industrial demands. With robust sealing and ease of use, the CS Series is critical for the safe sampling of liquefied gases or high-vapor-pressure liquids, making them widely used, especially in LNG storage, transportation, and chemical production.

  • Cylinder Configuration Sampling Systems for Gases, CG Series

    CGG Series Cylinder Configuration Sampling Systems for Gases are engineered for sampling corrosive and hazardous gases. They feature a reliable design to enable closed-loop gas sampling and prevent environmental contamination or human exposure caused by gas leaks. Configurations include system purge type, bypass and system purge type, and vent to flare type, catering to varied industrial demands. The simple design ensures long-term reliability, making it ideal for petrochemical plants, laboratories, and chemical processing.

  • Sampling Systems Accessories

    Sampling Systems Accessories include sample cylinders, cylinder accessories, valves, sample bottles, metal hoses, and quick-connects, ensuring efficient system operation. Quick-connects enable easy coupling and uncoupling, while needle assemblies and gaskets provide reliable sealing and durability during the sampling process. Metal hoses withstand high temperatures and pressures, making them suitable for complex working conditions. Available in multiple materials and sizes, these accessories accommodate various specialized sampling needs, ensuring safe and efficient operation in petrochemical, chemical, and laboratory applications.

  • Sampling Assemblies, Sample Cylinders and Accessories

    Sampling Assemblies, Sample Cylinders, and Accessories ensure safe liquid, gas, and liquefied gas sampling. Accessories include needle assemblies, rupture discs, tees, and outage tubes. Quick-connects with double-end shutoff provide excellent sealing performance and are interchangeable with other key manufacturers’ quick-connects. Rupture disc assemblies offer overpressure protection by automatically releasing pressure when it reaches the set value, ensuring system safety. The outage tube provides a vapor space of the desired volume to prevent overpressure due to temperature rise. All these accessories are made of premium corrosion-resistant materials such as 316L stainless steel and alloy 400, ensuring safe sampling in industrial, chemical, and laboratory applications.

  • Sample Handling Systems, SR Series

    SR Series Sample Handling Systems are designed for sample recovery and purging to ensure safety and environmental protection. They support sample recovery and cylinder emptying, making them suitable for working conditions requiring sample re-processing. The SRB Sample Recovery System for Bottles ensures efficient liquid sample recovery to prevent environmental contamination. The SRC Sample Emptying System for Cylinders is suitable for handling liquefied gases or venting high-vapor-pressure liquids, particularly in industrial and laboratory environments. SR Series systems offer easy operation and simplified maintenance, making them ideal for environmental protection and safe operation.
