Abstract

A microscopic sample production device comprises a groove (1), an inner sleeve frame (2) capable of being inserted and taken out along the inner side wall of the groove (1) and a mesh sieve capable of being placed at the bottom of the groove (1). The microscopic sample production device can produce samples dozens of times and even hundreds of times larger than traditional observation samples.

Description

technical field [0001] The invention relates to a micro sample preparation device. Background technique [0002] Microscopes can be used, for example, to identify traditional Chinese medicines, including observing the microscopic characteristics of Chinese medicinal ingredient powders in Chinese herbal medicines, decoction pieces, and Chinese patent medicines. [0003] At present, the microscopic identification of traditional Chinese medicine powder usually adopts slide glass and cover glass to make slices of traditional Chinese medicine for observation. The commonly used cover glass has a side length of 1.5cm and an area of ​​2.25cm 2 , remove the empty space on the edge, the area is about 2cm 2 . For some medicinal materials, such as Chinese yam, the content of calcium oxalate needle crystals with obvious identification significance is relatively small, and it is necessary to observe a large number of yams to find the image of calcium oxalate needle crystals. If the Ch...
