Abstract
The present invention provides a sampling capsule and a sampling capsule system. The sampling capsule includes an enclosure, a partition wall arranged in the enclosure, and a sample chamber enclosed by the partition wall and the enclosure at a first side of the partition wall. The sampling capsule further includes an inner sample inlet on the partition wall, an outer sample inlet, a sampling tube and a switch assembly. The outer sample inlet is on the enclosure at a second side of the partition wall. The sampling tube connects the outer sample inlet and the inner sample inlet, and the switch assembly clamps or unclamps a portion of the sampling tube. When sampling is needed, the switch assembly unclamps the sampling tube to sample liquid. When sampling ends, the switch assembly tightly clamps the sampling tube to prevent sample liquid leak or contamination.
