A solid-liquid mixture sampler and its sampling method

Abstract

The invention discloses a solid-liquid mixture sampler, which is characterized in that: from bottom to top, it comprises a glass slide (1), a middle layer of adhesive film (2), a cover glass (3), an upper layer of coating (4); the middle layer The adhesive film (2) includes a sampling cavity (5), the length of the sampling cavity (5) is greater than that of the cover glass (3), and after assembly, the two ends protrude from the edge of the cover glass (3), forming a first protruding part, the second protruding part and the middle part; the upper coating film (4) seals the cover glass (3), the middle adhesive film (2), and the slide glass (1) into one body to form a multi-layer stepped surface, but does not The upper part of the sampling cavity (5) is not covered. The present invention avoids adding a cover glass in use, and is easy to operate and fast in sampling; when dropping the sample, the sample is evenly dispersed in the empty groove of the sampler through the capillary phenomenon, and it is not easy to form air bubbles, the observation effect is good, and it is convenient for later image processing; and It is convenient to select samplers with different thicknesses for different samples.

Description

technical field [0001] The invention belongs to the technical field of microscopic detection of solid-liquid mixture, relates to the structure of a slide sampler, in particular to a solid-liquid mixture sampler and a sampling method thereof. Background technique [0002] In the sampling inspection of liquid or solid-liquid mixture, the cover glass is usually manually covered after dropping the sample on the glass slide; when it is necessary to control the height of the liquid level between the slide glass and the cover glass, this original sampling method It is usually not possible, so it is difficult to perform microscopic observation of substances with thickness in solid-liquid mixtures. However, the cost of controlling the height of the liquid level by using the common grooved plankton counting board and blood cell counting board; It is difficult to monitor during the process. If the flatness is not good, it will affect the determination of the focal plane of the microsc...

[0002] In the sampling inspection of liquid or solid-liquid mixture, the cover glass is usually manually covered after dropping the sample on the glass slide; when it is necessary to control the height of the liquid level between the slide glass and the cover glass, this original sampling method Usually not possible, so it is difficult to perform microscopic observation of substances with thickness in solid-liquid mixtures

However, the cost of controlling the height of the liquid level by adopting the common grooved plankton counting board and blood cell counting board; It is difficult to monitor during the process. If the flatness is not good, it will affect the determination of the focal plane of the microscope, and the image quality will decrease.

Moreover, the two still need to manually cover the cover glass after dropping the sample, which is inconvenient to operate and prone to air bubbles, which affects microscopic observation and hinders possible image recognition and processing in the later stage.
