Abstract

The invention relates to a plant chlorophyll determination process simplification device. The plant chlorophyll determination process simplification device comprises a mounting support, and a transparent reaction cylinder, a Buchner funnel and a volumetric flask are arranged on the mounting support, wherein the Buchner funnel is positioned at the lower part of the reaction cylinder, and the volumetric flask is arranged corresponding to a liquid outlet of the Buchner funnel; the reaction cylinder comprises a vertical main cylinder body, the upper part of the main cylinder body is connected with an extract solution injector and a solid substance inlet, and a liquid outlet valve and an iron wire mesh filter are arranged at the lower part in the main cylinder body; a crushing cutter is also arranged in the main cylinder body, and is hung on the mounting support; and quantification filter paper which can filter a plant extract solution is arranged in the Buchner funnel. The device combines grinding, extraction and filtration devices into a whole and can realize the streamlined operation of extraction and filtration in the chlorophyll determination process, improve the experimental efficiency, increase the experimental precision, treat a large batch of samples, and has good practical value.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to a device for simplifying the process of measuring plant chlorophyll. Background technique [0002] When measuring the chlorophyll content of plants, the laboratory often uses extracts to extract the chlorophyll in the plants, and then uses a tube photometer to measure the absorbance at wavelengths of 663mm and 645mm, and finally calculates the chlorophyll content. For the extraction of chlorophyll, the conventional method is to use a mortar to grind and filter to make a constant volume. The current grinding device is mainly operated by hand, and the degree of automation is not high. Waste of resources. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a plant chlorophyll measurement process simplification device, which combines grinding, extraction, and filtration devices into a whole to realize the extraction and filt...
