Description

Technical Field

[0001] The utility model relates to the technical field of spore-pollen extraction, in particular to a convenient water-changing device for spore-pollen extraction. Background Art

[0002] Spores and pollen (spores and pollen), important components of plant reproductive organs, possess advantages such as small size, high yield, strong outer walls, stable morphology, easy preservation, and ease of extraction. These advantages make them the most direct, reliable, and detailed records besides large fossils. Therefore, spore and pollen analysis is crucial for our study of paleoclimate and paleoenvironment. We refer to the soil or sedimentary rocks collected containing spores and pollen as samples. Spores and pollen are very small, with particle sizes ranging from a few to tens of microns. They are dispersed within the sample and difficult to observe with the naked eye, yet they hold significant research significance in the fields of geography, environment, and geology. Therefore, they must be extracted from the sample.

[0003] In the pollen extraction process, various acid and alkali reagents are needed to remove impurities from the sample. These acids and alkalis can dissolve or react non-pollen substances in the sample, facilitating subsequent pollen separation and extraction. After acid and alkali treatment, water washing until neutral is very critical. This is because after acid and alkali treatment, unreacted acid and alkali reagents remain in the sample, and these residues will affect the extraction effect. Therefore, multiple water washings are required to gradually wash out the acid and alkali reagents from the sample until the sample is neutral. Currently, water washing has always adopted the manual water change method, that is, a latex tube is first filled with distilled water, and one end is inserted into the acid or alkali solution, and the other end is lower than the liquid surface. The gravity difference is used to make the liquid flow out, and then distilled water is added to the plastic cup. After clarifying for at least 8-12 hours, the liquid is extracted again until it is neutral. The existing manual water change method can only absorb water from one sample at a time, and it is easy to stop working due to gas leakage in the tube. It is cumbersome and time-consuming.
