Problems solved by technology

In the traditional concentration method, it is necessary to use a precipitator, and the sample can be prepared by repeated precipitation and constant volume. However, the precipitator is large in size and made of glass, which is easy to break. This kind of precipitator is not suitable for field survey monitoring and sample collection. It is easy to carry around, and taking the sample back to the laboratory for concentration operation will delay the preparation of the sample, greatly reducing the accuracy and representativeness of the sample
At the same time, in the actual monitoring and sampling in the field, the sample volume is large, and carrying samples has become a big problem. The carrying of a large number of samples restricts the efficient conduct of field monitoring and increases the burden on sampling personnel.

Abstract

The invention discloses a portable concentration device for quantitative samples of planktons. The portable concentration device comprises a bracket part and a siphon part, wherein the bracket part consists of a horizontal bracket and vertical brackets; a ring-shaped pipe is welded at the upper end of each vertical bracket, and the vertical brackets are fixed on the horizontal bracket at certain intervals by using fixed bolts; the siphon part comprises latex tubes, flow-speed adjusters, air bags and spiral water stopping clamps; the latex tubes are connected with the flow-speed adjusters and penetrate through the flow-speed adjusters; the air bags are connected to the latex tubes; the other ends of the air bags are connected with the latex tubes; the spiral water stopping clamps are placed on the latex tubes; the latex tubes are fixed on the horizontal bracket and the vertical brackets by binding belts. The portable concentration device disclosed by the invention has the advantages that the structure is simple, the cost is low, the carry is portable, the assembly is fast, the use is convenient, high-efficiency and accurate effects are achieved, and the device can be effectively applicable to the concentration quantification of fixed samples in hydrobiology; the carrying amount of the field quantitative samples can be greatly reduced and the working efficiency is improved.

Description

technical field [0001] The invention relates to a concentration and separation device, in particular to a concentration of quantitative samples in aquatic biology research, which is suitable for quantitative samples of aquatic biology that need to be concentrated in large quantities when conditions in non-fixed places are limited. Background technique [0002] Siphon is a hydrodynamic phenomenon that can pump liquid without the action of a pump to realize the transfer of liquid. The principle of siphon can be applied to all aspects, ranging from water conservancy projects to household drainage. Reasonable use of its physical characteristics can easily move fluid materials, saving time and effort. [0003] In the research of aquatic biology, it is often necessary to collect a certain volume of water samples and fix and concentrate them to prepare a certain volume of concentrated samples for the qualitative and quantitative detection of plankton. In the traditional concentrat...
