Extraction mortar for botanical experiment

Abstract

The invention discloses an extraction mortar for a botanical experiment. The extraction mortar comprises a fixed seat, a rotating shaft, a base, a mortar body, a mortar cover, a grinding hammer and apressure applying mechanism, the middle position of the fixed base is provided with a rotating shaft hole, and the rotating shaft is rotatably arranged in the rotating shaft hole in a penetrating mode; the lower end of the rotating shaft is connected to a driving motor, the base is provided with a clamping groove, the base is placed on the fixed seat, and the rotating shaft is detachably clamped into the clamping groove; the mortar body is arranged on the base, the mortar cover is arranged on the mortar body, the middle of the mortar cover is provided with a through hole, and the mortar coveris made of a transparent material; the grinding hammer penetrates through the through hole, and a hammer head of the grinding hammer is located in the mortar body; and the pressure applying mechanismcomprises a bracket, a pressing block and a lifting mechanism, and the pressing block is arranged on the bracket in the mode of being capable of moving in the vertical direction, the lifting mechanismis connected to the pressing block to drive the pressing block to move downwards, and the pressing block abuts against the upper end of a hammer handle of the grinding hammer, so that the hammer headof the grinding hammer abuts against the bottom of the mortar body in a pressing mode. The extraction mortar for the botanical experiment reduces the operation difficulty of experimenters and avoidsharm to bodies of the experimenters.

Description

technical field [0001] The invention relates to experimental pretreatment equipment, in particular to an extraction mortar for botany experiments. Background technique [0002] In the experiment of physiological and biochemical indicators in botany, it is often necessary to extract catalase, malondialdehyde, superoxide dismutase, chlorophyll, vitamin C and other substances in fresh plant leaves for scientific research. grinding with a bowl, and some toxic, harmful and volatile reagents are sometimes added during the grinding process, such as acetone used for chlorophyll extraction, due to its strong volatility, it will be volatilized during the grinding process, causing the experimenter’s body to suffer harm. In addition, the experimenters will add liquid nitrogen during the grinding process to improve the grinding efficiency, but ignore the risk of freezing damage to the left hand that fixes the mortar. So there is a need for a mortar with a grinding cover and a mortar fi...
