Technical Field
[0001] The utility model relates to the technical field of biological experimental equipment, in particular to a two-worm enrichment and concentration device. Background Art
[0002] Cryptosporidium and Giardia (the "two worms") are two pathogenic protozoa that parasitize humans and animals. In recent years, there have been many outbreaks of waterborne diseases caused by the "two worms" in water both at home and abroad.
[0003] When the existing two-worm precipitation and enrichment device is used for two-worm precipitation and enrichment, it is necessary to first pour the stock solution into the container in the precipitation and enrichment device, and then add reagents to the stock solution to adjust the pH value of the stock solution. When the pH value of the stock solution is adjusted to the required value, it is left to stand for a period of time to allow the two worms to precipitate. After the precipitation is completed, the upper clear liquid in the container is pumped out by a peristaltic pump.
