Plankton concentration device suitable for various sampling containers and use method

Abstract

The invention relates to the technical field of plankton monitoring, in particular to a plankton concentration device suitable for various sampling containers and a using method.The plankton concentration device comprises a support, the lower portion of the support is detachably connected with a plurality of sedimentation concentration bottles through third fixing rings, and the sedimentation concentration bottles are detachably connected with sample bottles through circular rings; the sample bottle is detachably connected with the support through the first fixing ring and the second fixing ring, a semicircular opening is formed in the lower portion of the outer wall of the sedimentation concentration bottle, and a waterproof silica gel sealing strip used for preventing water in the sedimentation concentration bottle from flowing out is embedded in the semicircular opening. The waterproof silica gel sealing strip is detachably connected with a water separation insertion plate for separating the interior of the sedimentation concentration bottle, the outer wall of the sedimentation concentration bottle above the semicircular opening is fixedly connected and communicated with a one-way valve for preventing water in the sedimentation concentration bottle from flowing out, and one end, extending out of the sedimentation concentration bottle, of the one-way valve is detachably connected with a double-channel head. According to the invention, not only is manual operation reduced, but also the precision of sediment concentration is effectively improved.
