Sampling system, also known as sampler, it is an equipment
used for representative sample collection from process,
pipeline and storage tank.

Due to the growing complexity of the industrial processes, the need for
products testing and analyzing increases continuously, and safety for
sampling process is taken more and more consideration,
simple primitive sampling system evolved into safe and reliable
closed-loop sampling system.
Closed-loop sampling system is separated into bottle configuration and
cylinder configuration according to the container, the difference of this
two configurations is container form and sealing type : Bottle configuration
sampling system is sealed with an automatically sealed septum; Cylinder
configuration is sealed by the needle valves equipped at both ends
of the cylinder.
