Just.
Preferably, the push rod is fixedly connected with backwards to convex portion one end prevents medium body by the lid of living contaminants,
The lid is provided with the plug of stifled tightening seal culture medium, and plug is adapted with medium body opening.
Preferably, the medium body opening is provided with slotting ring, correspondingly, the lid is provided with for slotting ring intercalation
Annular groove.Slotting ring insertion annular groove to be in a sterile sealed environment inside medium body so that in medium body not
It is vulnerable to the pollution of miscellaneous bacteria.
Preferably, the operation shank is provided with the cotton swab for being used for being infected with thalline backwards to convex portion one end.
Preferably, the loop-carrier is made up of high temperature resistant, high pressure material, such as PC.
The beneficial effects of the utility model are：
In the utility model, operation shank and the inoculation detachable design of shank so that testing staff samples in inoculation
During completion, operation shank need to only be extracted, and be inoculated with shank and stay in inside medium body, without testing staff
Loop-carrier is cut using scissors, also eliminates the process to be carried out disinfection to scissors, sample detecting process is more convenient, fast.
Meanwhile operation shank can be used to continue to gather next bacterium colony sample for testing staff, realize that operation shank is recycled
Use, so as to greatly reduce the cost of sample detecting, be also beneficial to making full use of for resource.
