Thermal insulation anti-slip type mortar for tests

Abstract

The invention relates to a thermal insulation anti-slip type mortar for tests, and the mortar includes a mortar body, a cover and an insulating plug. The mortar body is in a multilayer structure, decorative patterns are on the surface of an anti-slip layer, the cover is matched with an opening formed on the upper portion of the mortar body, and a flip cover is arranged on the cover. A pestle mounting hole is formed at the center position of the cover, a mounting concave is arranged on the upper surface of the pestle mounting hole, and the mounting concave is matched and installed with the insulating plug. The gap between the insulating plug and the mounting concave is sealed, the insulating plug is provided with a center hole which is arranged corresponding to the pestle, and the pestle is arranged by penetrating through the center hole of the insulating plug, the corresponding middle position of the mounting concave and a pestle mounting hole at the center position of cover. A sealing sleeve is coated on the pestle, wherein a center hole mounting hole at the bottom of the mounting concave. The thermal insulation anti-slip type mortar for the tests has the advantages that an anti-slip thermal insulation layer is added outside the mortar body, and the cover for preserving heat is added and is provided with the pestle mounting hole capable of heat insulation, so that insulation capacity of the mortar body is improved, and meanwhile the mortar has an anti-slip function.

Description

technical field [0001] The invention belongs to the technical field of mortar for testing, in particular to a mortar for thermal insulation and non-slip testing. Background technique [0002] A mortar is a commonly used experimental tool for grinding solid substances or mixing powdered solids. However, in experiments, especially in the nucleic acid extraction process of biological samples, there is often a requirement to treat specimens with liquid nitrogen at low temperature. The boiling point of liquid nitrogen is minus 196 degrees. The existing mortar cannot meet the test requirements well. In the experiment, accidents of frostbite of the experimenter's hands and liquid nitrogen splashing often occurred in the mortar. Even if the experimenter wears thick gloves, it is difficult to avoid these situations. Moreover, the outside of the mortar is frozen due to low temperature, and the friction coefficient becomes smaller. During the grinding process , The mortar is easy to s...

However, in experiments, especially in the nucleic acid extraction process of biological samples, there is often a requirement to treat specimens with liquid nitrogen at low temperature. The boiling point of liquid nitrogen is minus 196 degrees. The existing mortar cannot meet the test requirements well. In the experiment, accidents of frostbite of the experimenter's hands and liquid nitrogen splashing often occurred in the mortar. Even if the experimenter wears thick gloves, it is difficult to avoid these situations. Moreover, the outside of the mortar is frozen due to low temperature, and the friction coefficient becomes smaller. During the grinding process , the mortar is easy to slide on the test bench and cause the sample and liquid nitrogen to spill out, affecting the success rate of the experiment
