Abstract

The invention discloses a freezing slicer for botany experiments, which comprises a double-shaft motor, a first blade, a second blade, a driving gear, a ratchet gear, a ratchet bar and the like, and is characterized in that the double-shaft motor is arranged to rotate in a certain direction, so that the driving gear can rotate to further drive the ratchet gear to displace along the arrangement direction of the ratchet bar; the first blade and the second blade are displaced; then, the rotating direction of the double-shaft motor is changed, and the first blade and the second blade can rotate through the design of the driving wheel and the driven wheel to cut the plant tubers. According to the design, manual operation for secondary cutting is not needed, the efficiency can be effectively improved, the operation steps are simplified, the safety during cutting can be improved, and an operator is prevented from being cut.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a frozen slicer for botanical experiments. Background technique [0002] Frozen section refers to a method that uses low temperature to freeze the tissue quickly and slice it after reaching a certain hardness. Because it does not need to go through steps such as dehydration and transparency, it is fast, simple, easy to operate, and can be preserved better. The enzyme activity of the tissue, which preserves the immune activity of the tissue antigen relatively well, is a commonly used method in experiments such as in situ hybridization, enzyme histochemistry and immunohistochemistry. [0003] However, the existing cryostats have the following problems in use: when slicing, manual operation is required to cut twice, first to cut a plane, and then to perform secondary slicing according to the thickness of the required slice, and the steps are cumbersome; the environmen...
