Abstract

The invention discloses a safe environment-friendly plankton rapid concentrating device and a use method thereof. The rapid concentrating device comprises a base, a fixed rod, two glass elbows, a Y-shaped glass elbow and a collecting container. Clamping components for clamping and fixing the two glass elbows respectively are arranged on the fixed rod. The two glass elbows and the Y-shaped glass elbow are correspondingly connected through two silica gel hoses. The rapid concentrating device further comprises a backflow clamp for alternately clamping one of the silica gel hoses. All the components in the rapid concentrating device are common components for a laboratory and are low in price and rapid to detach, assemble and combine; the sample concentration operation method is simple and easy to implement, the concentration operation time can be effectively shortened, and work efficiency is improved. Sample concentration conducted through the rapid concentration device is simple, accurate and rapid; in the whole concentration operation process, samples are in a closed state, and the health of operators can be protected and the pollution to the environment can be reduced.

Description

technical field [0001] The invention relates to the technical field of water body ecological research devices, in particular to a method for using a safe and environment-friendly plankton rapid concentration device. Background technique [0002] Plankton refers to organisms suspended in water bodies, including phytoplankton and zooplankton, which are important indicator organisms in river and marine ecological surveys and biological monitoring. In actual scientific research activities, the collected plankton samples often need to be fixed with Lugol's solution or 3-5% formaldehyde solution, and brought back to the laboratory for qualitative and quantitative analysis after concentration. [0003] Due to the large amount of samples, and the formaldehyde solution has the characteristics of strongly irritating eye membranes and respiratory organs, it not only poses a health hazard to the experimenters, but also causes certain pollution when the fixative solution is discharged in...
