BLD5 – Sampling by Gravity Type with Heating/Cooling Jacket


  • Sampling from medium or high pressure devices or process lines
  • Fixed volume sampling
  • System purge
  • Sampling by gravity without Nitrogen purge
  • Heating/cooling jacket to ensure sampling within a certain range of temperature
  • Easy operation with a single handle by linkage valve.

Typical Installation Mode

1 – Preperation

Place a new septum on the sample. Insert the bottle with cap and septum into the sleeve until the septum is pierced by the needles. Swing down the bottle retaining clip.

2 – System Purge

Turn the handle to the “BYPASS” position, allowing the sample to flow continuously through the sample chamber. Hold for a period of time to ensure representative sampling.

3 – Heating/Cooling

Turn the handle to the “OFF” position, allowing the heating/cooling fluid to flow through the heating/cooling jacket. Hold for a sufficient time until the sample reaches the required temperature.

4 – Sampling

Turn the handle to the “SAMPLE” position, allowing the sample to flow into the bottle of gravity. Hold this position for a sufficient time. The amount of sample depends on the sample chamber volume.

5 – Off

Turn the handle to the “OFF” position to close the sampling system. Remove the bottle retaining clip and take out the bottle from the sleeve. The septum reseals automatically to complete the sampling process.
