Through setting up cyclic annular cutting board, the operator of being convenient for breaks the pharynx swab fast, reduces the infection risk.
The utility model relates to a save set's of general type nucleic acid conservator further improvement lies in, and the free end of cyclic annular cutting board is formed with the blade.
The utility model relates to a save set's of general type nucleic acid preservative solution further improvement lies in, is formed with the recess that holds the sealing washer on the flange.
The utility model relates to a save set's of general type nucleic acid preservative solution further improvement lies in, and the bottom of test tube is provided with counter weight or slipmat. For preventing toppling.
The utility model relates to a save set's of general type nucleic acid preservative solution further improvement lies in, and the below of cyclic annular cutting board is provided with the flexure strip, runs through on this flexure strip to be provided with "rice" style of calligraphy incision. Inside the pharynx swab got into the test tube through "rice" style of calligraphy incision, simultaneously, the flexure strip made "rice" style of calligraphy incision self-sealing under the elastic action, prevented that the in vitro solution from leaking outward.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1. through setting up cyclic annular cutting board, the operator of being convenient for breaks the pharynx swab fast, reduces the infection risk.
2. Inside the pharynx swab got into the test tube through "rice" style of calligraphy incision, simultaneously, the flexure strip made "rice" style of calligraphy incision self-sealing under the elastic action, prevented that the solution of in vitro from leaking outward.
