Cell counting chamber, mould and method for manufacturing cell counting chamber

Abstract

The invention provides a cell counting chamber comprising a box body and a first substrate, wherein the box body comprises a second substrate and a wall arranged around the second substrate; a boss is formed on the inner side of the upper edge wall of the second substrate; anti-shrinkage grooves are formed on the second substrate; the anti-shrinkage grooves are arranged on an inner surface of the second substrate formed with the boss and an outer surface opposite to the inner surface, and the anti-shrinkage groove on the inner surface is close to the boss; the first substrate is embedded in the box body, and forms a counting chamber cavity together with the second substrate and the boss; and an opening structure which is communicated with the counting chamber cavity and is used for loading a sample to the chamber is formed on the counting chamber cavity. The cell counting chamber disclosed by the invention, through the anti-shrinkage grooves, can reduce shrinkage deformation of a middle part which is relatively low in thickness, so that the inner surface and the outer surface are smoother. Furthermore, the invention provides a mould for injection-moulding the cell counting chamber, and a method for manufacturing the cell counting chamber through the mould.

Description

technical field [0001] The present invention relates to the technical field of cell counting, and more specifically, relates to a cell counting plate, a mold for injection molding the cell counting plate, and a method for manufacturing the cell counting plate by using the mold. Background technique [0002] In biological research, it is sometimes necessary to measure the number of cells per unit volume. In the existing counting process, a cell counting plate is generally used to measure the number of cells. [0003] The existing cell counting board is composed of a box body and a substrate arranged in the concave space of the box body, wherein there is a gap between the bottom surface of the concave space of the box body and the substrate, and this gap space is the counting pool cavity of the cell counting board, and the sample Liquid is introduced into this counting cell cavity and it can be counted. [0004] Since it is necessary to use a microscope to observe the samples...

AI Technical Summary

Problems solved by technology

The function of the cell counting board is to assist personnel to count small cells, so the manufacturing process of the cell counting board has high requirements on the flatness of the box and the substrate, and the transparent plastic box and the substrate are in the manufacturing process. The shrinkage that occurs will have a great impact on the flatness of the surface, making the focus of the microscope inaccurate and affecting the use of the cell counting plate
