Description
Technical Field
[0001] The utility model relates to the technical field of laboratory drying dish equipment, in particular to a drying dish for preventing cross contamination. Background Art
[0002] In laboratories, desiccating dishes are often used to dry experimental samples to prevent moisture from affecting the experimental results. For example, in chemical experiments, certain reagents need to be kept dry to ensure the accuracy of the experiment; in biological experiments, certain biological samples need to be stored in a dry environment to prevent deterioration.
