Embodiment Construction

[0019] Such as figure 1 Shown is the embodiment of the sorting device for living zooplankton samples of the present invention, comprising a U-shaped tube 10, the lower end of the U-shaped tube 10 is connected with a collection chamber 20, and the connection between the U-shaped tube 10 and the collection chamber 20 is provided with a first valve 11 controls the closed opening, and one end of the U-shaped tube 10 wraps the light-shielding layer 30 .

[0020] The living zooplankton sample sorting device of this embodiment can separate zooplankton according to two types of phototaxis and light avoidance by setting light and dark conditions in the U-shaped tube 10; at the same time, by controlling the first valve 11, the deposited debris can and benthic species flow into the collection chamber 20 from the opening at the junction of the U-shaped pipe 10 and the collection chamber 20, thereby achieving the purpose of preliminary sorting the mixed samples of zooplankton living bodies...

Abstract

The invention relates to the field of sorting devices, in particular to a sorting device for treating marine organism samples, namely zooplankton living body samples. The sorting device comprises a U-shaped tube, wherein a collection chamber is connected to the lower end of the U-shaped tube; an opening which is controlled by a valve to be closed is arranged at the connected part of the U-shaped tube and the collection chamber; and one end of the U-shaped tube is wrapped by a shading layer. The sorting device for the zooplankton living body samples, which is provided by the invention, can be used for classifying the collected zooplankton living body mixed samples; zooplanktons can be separated according to phototaxis and lucifuge by setting bright and dark conditions for the U-shaped tube; meanwhile, the settled scraps and benthoic varieties can be enabled to flow into the collection chamber from the opening at the connected part of the U-shaped tube and the collection chamber by controlling the valve, thereby achieving the aim of preliminarily sorting the zooplankton living body mixed samples with different habits, greatly shortening the shorting time and facilitating the furtherresearch on physiological and ecological characteristics of the zooplankton living body mixed samples.

Description

technical field [0001] The invention relates to the field of sorting devices, in particular to a sorting device for living zooplankton samples used for processing marine biological samples. Background technique [0002] Zooplankton is a secondary consumer in the marine ecosystem. It plays a connecting role and is an important nutritional link in the traditional food chain. Its quantity change and spatial distribution are important to the functioning of the entire marine ecosystem and even global climate change. effect. Different species of zooplankton have different ecological habits and play different roles in the food chain. Selecting a living sample of a certain species of zooplankton for indoor monoculture and experimentation is one of the effective means to study its physiological ecology. [0003] At present, to classify the collected mixed samples of living zooplankton, the method of sorting the mixed samples directly under a stereo microscope is mainly adopted, whic...
