The tube body has a mounting plate and a notch at the connection part, an external thread and a rubber ring on the outer side wall, and a limit baffle and a baffle on the inner side wall. The internal thread mates with the external thread, and the tube is made of polypropylene to improve sealing and durability.
It achieves stable breakage of the swab rod, prevents the swab head from popping out and liquid from splashing, improves collection efficiency and safety, and ensures the integrity and sealing of the sample.
