the cover glass comprises a cover glass body made of transparent plastic, wherein a protruding part used for preventing adhesion and ensuring uniform liquid level thickness of a sample on a glass slide is arranged on one surface of the cover glass body; the cover glass body is provided with a recognition part for preventing reverse placement.
The thickness of the convex part is 0.03 mm-1.0 mm.
The identification part is of a notch structure; the projection is a protruding sheet arranged on the upper surface of the cover glass body.
The notch structure is a groove arranged at the edge of the cover glass body.
The notch structure is a chamfer, a fillet or a groove arranged at the corner of the cover glass body.
The number of the protruding pieces is two, and the two protruding pieces are arranged on the upper surface of the cover glass body in parallel at intervals.
The lug is an annular structure arranged at the peripheral edge of the cover glass body.
The number of the lugs is four, and the lugs are respectively arranged at each corner of the cover glass body.
The invention has the advantages that the convex part can not only reduce the contact area between the sheets, avoid the adhesion phenomenon between the cover glass sheets, facilitate taking and holding, but also facilitate quickly distinguishing the front and back sides of the cover glass sheets, and can limit the height of the liquid level of the sample, so that the sample on the glass slide is uniformly distributed; the identification part can ensure that the storage directions of the cover slips are the same, the cover slips are easy to identify, the occurrence of reverse arrangement is completely avoided, the rapid detection requirement of automatic detection equipment can be met, and the interpretation accuracy is high; meanwhile, the cover glass body is made of the high-light-transmittance transparent plastic after hardening treatment, so that the hardness and the surface flatness of the cover glass body are increased, and the breakage probability of the cover glass in use is reduced.
