Phytoplankton quantify sample precipitation concentration be phytoplankton Number and biomass monitoring important link.It is concentrated
Principle be that Shandong brother reagent is added in the 1L water sample that will acquire, phytoplankton is stood under the action of the brother's reagent of Shandong, is deposited in bottle
Supernatant is precipitated in bottom, carries out constant volume to phytoplankton sample.When phytoplankton quantifies sample acquisition and concentration, water sample is usual
After staticly settling 24-48h after being transported to laboratory, to sop up supernatant with siphon pipe, be transferred to it is to be measured in sample bottle, to
The constant volume for realizing preceding sample to be measured then needs to shift again, stand, siphon, expends the longer time, if this method is used for field
The acquisition of bulk sample is concentrated, and one side freight volume is big, and on the one hand time-consuming, and sample has loss.Therefore, it is necessary to design one kind
The phytoplankton sample concentration device be readily transported, reduce sample processing time, improving accuracy.
Utility model content
To solve the above problems, the utility model provides a kind of portable phytoplankton sample concentration device, especially
It is the enrichment facility that a large amount of phytoplanktons in field quantify sample.It is easy to operate, quick, primary quiet heavy it can realize determining for sample
Hold, and effectively reduce the loss of sample, improve the accuracy of sample detection, reduces transport space.
To achieve the above object, the technical scheme adopted by the utility model is that: a kind of portable phytoplankton is quantitative
Sample concentration device, which is characterized in that including compressible sample bottle and sample reception bottle；It is characterized by: compressible sample bottle
Equipped with injection port with cover, upper screw thread, lower screw thread, compressible portion and outlet valve, wherein compressible sample bottle top is equipped with
Injection port with cover, injection port connect upper screw thread, are above threaded through compressible portion and connect lower screw thread, compressible portion bottom end one
Side is equipped with outlet valve, is controlled by movable valve；Sample reception bottle bottleneck is equipped with internal screw thread, external screw thread and bottle cap, and internal screw thread is used
In the connection of sample reception bottle and compressible sample bottle, external screw thread is screwed for sample reception Bottle and bottle cap.
Further, the compressible sample bottle is flexibly connected with sample reception bottle, and both can connect can also take out,
Compressible sample bottle is connected with sample reception bottle by screw thread mouth.
Further, sample reception bottle body product is 30ml.
Further, it when quantifying sample progress precipitation concentration to phytoplankton, connects compressible sample bottle and is connect with sample
Bottle is received, phytoplankton is deposited in sample reception bottle, after the supernatant discharge in compressible sample bottle, with a small amount of clear major general
After the phytoplankton of wall built-up rinses sample reception bottle, directly take out to be checked.On the one hand reduce conventional method sample repeatedly to turn
The time for moving concentration, realize the quick constant volume of sample；On the other hand the space needed for reducing sample during transportation.
Further, the compressible sample bottle has outlet valve, after sample pellet concentration, can be arranged by outlet valve
Fall the supernatant in compressible sample bottle, interference is not generated to the sample in sample reception bottle, reduce the loss of algae, improves sample
The accuracy of product.
The working principle of the utility model is: compressible sample bottle and sample reception bottle are not in sampling tool transportational process
Connection, compressible sample bottle are in compressive state, reduce transport space.When needing precipitation concentration, compressible sample bottle is stretched, is connected
Compressible sample bottle and sample reception bottle, 1L water sample enter through injection port, after addition Shandong brother reagent is fixed, stands for 24 hours, open out
Water valve releases supernatant, rinses wall built-up phytoplankton with a small amount of water, cantilevered out sample reception bottle screws on bottle cap, and preservation is transported to experiment
Room is to be measured.
The utility model has the following beneficial effects: device is compressible, and it is easy to carry, it is easy to operate, quick, it can be primary quiet
The heavy constant volume for realizing sample, can effectively reduce the loss of sample, improve the accuracy of sample detection, reduce transport space.
