NEST Petri dishes with safelock design has several protrusions on the top circumference of the dish body, and several buckles corresponding to the protrusions on the inner circumference of the cover.

The lower end of each buckle is designed with a slope surface, and the upper end is designed with a card slot that allows the protrusion to slide into. After the medium is filled, turn the dish lid clockwise, and screw it into lock position to realize the lock function. This unique structural design ensures that the lid and the bottom of the dish will not fall off automatically during the experiment, avoiding contamination.
