Description

Technical Field

[0001] The utility model belongs to the technical field of culture dishes, and in particular relates to a high-density rotifer counting device. Background Art

[0002] When rotifers are cultivated at high density, the density of rotifers must be measured, that is, how many rotifers are contained per milliliter. The usual method is to use a pipette to draw 1 ml of rotifer liquid, drop it in a culture dish and then observe and count it under a microscope, or use a hemocytometer to count it. However, due to the large number of rotifers, it is often difficult to count large-area samples in the culture dish directly under a microscope. In addition, rotifers have the characteristic of constant movement, which often results in repeated counting. Killing the rotifers with drugs and then counting them makes the experiment cumbersome. The hemocytometer cannot count all the rotifers, and the results have a large error.

[0003] The existing patent (application number: CN201520102551.9) proposes a high-density rotifer counting device, including a transparent hard carrier, wherein the front or back side of the transparent hard carrier bearing part is engraved with lines that divide the transparent hard carrier into multiple areas; spiral lines and small circles are drawn on a culture dish or a transparent glass plate, and then small drops of a quantitative rotifer solution to be counted are dropped between the spiral lines or in the small circles, and then the number of rotifers in the small droplets is counted under a dissecting microscope to obtain the total number of rotifers. This device is simple and low-cost, and can conveniently, quickly and accurately obtain the number of high-density rotifers.

[0004] The existing rotifer counting device is difficult to maintain a stable placement state when counting the number of rotifers. During operation, the rotifer counting device may be offset due to external collisions, which may easily lead to counting errors.

[0005] In view of this, this application is hereby filed. Utility Model Content
