Phytoplankton Siphon Device

Abstract

The present invention discloses a phytoplankton siphon apparatus, which comprises: a container for accommodating a water sample, wherein the container is provided with an opening; a first disc body fixedly arranged on the opening of the container and provided with a guide hole, wherein the extending direction of the guide hole is perpendicular to the horizontal plane inside the container; a suction pipe, wherein the suction pipe comprises a hard pipe section and a soft pipe section, the hard pipe section can vertically and slidably inserted in the guide hole, the lower end of the hard pipe section is vertically inserted into the position below the horizontal plane inside the container, the hard pipe section wall exposed to the container is provided with scale lines, the lower end surface of the hard pipe section is sealed, and the side wall extending into the waster surface is provided with a suction port; a second disc body fixedly arranged on the hard pipe section outer wall provided with the scale lines; and a float, wherein the float floating on the water surface of the container, and the hard pipe section penetrates through the float and is fixedly connected with the float. With the phytoplankton siphon apparatus of the present invention, the stirring on the phytoplankton can be avoided, and the experiment accuracy can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of phytoplankton analysis facilities, in particular to a phytoplankton siphon device. Background technique [0002] Phytoplankton is an indicator organism for measuring water quality. The water quality of a water area is closely related to the richness of plankton and the composition of the community. Therefore, the ecological analysis of phytoplankton is an important content in the study of water ecology. [0003] In the prior art, a siphon device is usually used for siphon sampling of phytoplankton. At present, the laboratory phytoplankton siphon device mainly includes two types. One of the siphon devices includes a support column, a U-shaped base and a fixing clip. The support column is vertically fixed on the On the U-shaped base, scales are engraved on the supporting column, and one end of the fixing clip is movably connected to the supporting column, and can move up and down on the supporting column, ...

AI Technical Summary

Problems solved by technology

Since the phytoplankton need to go through layers of siphons, if the device is to achieve this purpose, the fixing clip must be manually moved up and down, which will cause agitation to the water in the device, and the U-shaped base will touch the phytoplankton at the bottom of the collection bottle, Affect the accuracy of the experiment
