Description
Technical field
The utility model belongs to water ecology research field, relates to a kind of water ecology research pick-up unit, is specifically related to a kind of siphoning installation for the quantitative sample concentration of planktonic organism.
Background technology
Planktonic organism occupies critical role in the food chain of aquatic ecosystem.In pond ecosystem, phytoplankton is the first link (also claiming the 1st trophic level) as the producer, phytophagous feeding of zooplankton phytoplankton, it is the second link (also claiming the 2nd trophic level), the output (primary productivity) of phytoplankton decides the output (secondary productivity) of phytophagous animal plankton, and the latter decides the output (3 grades of yield-power) of small fishes and the output (whole level yield-power) of larger fish.In addition, one of the important indicator of phytoplankton or body eutrophication monitoring.As can be seen here, all significant in scientific research and production practices to planktonic quantitative test.In quantitative test, the concentrated pre-treatment of sample is the key of carrying out taxonomic identification, counting.
The method the most frequently used to concentrated pre-treatment is at present, gather water sample 1L, after Shandong brother's reagent is fixing, sample shakes up to be poured in fixing settling vessel on the top of the shelf, fully after precipitation (24-48h), is released by bottom settlings by the outlet valve bottom settling vessel, control outlet valve, flow velocity, flow can not be too large, can not shake settling vessel, otherwise will again precipitate in this process.Put into the quantitative sample bottle of 100ml containing sedimentary water sample, if volume is greater than 30ml, then also need standing 24h, if volume is less than 30ml, before counting, constant volume is to 30ml.There is following shortcoming in this method: inconvenient operation, wayward flow and flow velocity; Equipment volume is large, is difficult to carry, is unfavorable for processing test sample in the wild, and the quantity of process test sample is also very limited.
Summary of the invention
In order to solve above-mentioned prior art Problems existing, the utility model provides a kind of siphoning installation for the quantitative sample concentration of planktonic organism, this apparatus structure is simple, with low cost, detachably, after dismounting, volume is little, be easy to carry, be applicable to the rapid concentration process of planktonic organism test sample, batch processing can be carried out to multiple test sample, the work efficiency increased substantially in the wild simultaneously.
Realizing the technical scheme that the utility model above-mentioned purpose adopts is:
A kind of siphoning installation for the quantitative sample concentration of planktonic organism, comprise the woven hose of the sampling bottle of band inner cap or bottle stopper, glass bend pipe, plankton net and band flow controller, the centre of inner cap or bottle stopper is provided with through hole, the lower end of glass bend pipe is arranged in sampling bottle through through hole, the diameter of through hole matches with the external diameter size of glass bend pipe bottom, the upper end of glass bend pipe is fixedly communicated with woven hose, glass bend pipe and woven hose form the siphon passage of U-shaped, and plankton net fixed packet is wrapped in the port of glass bend pipe lower end and is arranged in sampling bottle.
Described glass bend pipe is the elongated L-shaped glass bend pipe in one end, and one end that glass bend pipe is elongated is inserted in the infusion tube of woven hose.
Described plankton net has layer 2-3 screen cloth, and the specification of plankton net is 25#.
As shown from the above technical solution, gather water sample and pour in sampling bottle, then add a certain amount of immobile liquid with fixing planktonic organism, after 48h, carry out siphon again.When starting siphon, first be assembling siphoning installation, glass bend pipe is inserted through bottle cap or bottle stopper, then plankton net is wrapped in the lower port place of glass bend pipe and plankton net is placed in sampling bottle, cover bottle cap or jam-pack bottle stopper again, finally the upper end of glass bend pipe is fixedly communicated with the flexible pipe of woven hose, makes the other end of woven hose lower than the plane at place bottom sampling bottle.After assembling, glass bend pipe and woven hose form siphon passage, the flexible pipe can pinching woven hose to produce negative pressure to produce siphon or to adopt other mode to produce siphon when assembling, after siphon starts, until the position of glass bend pipe lower end stops siphon higher than the liquid level of sampling bottle.As can be seen here, this apparatus structure is very simple, and assembly and disassembly are very convenient, is easy to use quick.
Compared with prior art, the beneficial effects of the utility model and advantage are:
1) this apparatus structure is simple, and each parts are all very common and cheap, and thus cost is very cheap.
2) these device assembly and disassembly are very convenient, and each parts are light, are easy to carry, and can carry out batch processing, the work efficiency increased substantially in the wild to multiple test sample simultaneously.
3) this device is provided with plankton net at the lower port place of glass bend pipe, planktonic loss in siphonic process can be prevented, glass bend pipe can move up and down the amount controlling siphon in addition, and the flow controller of woven hose can control the speed of siphon, therefore use this device accurately can control the amount of concentrating sample and control planktonic loss, improve the accuracy of measurement result.
4) this device takes full advantage of siphon principle, without the need to any expulsive force, and keeps an eye on without the need to manpower.
Accompanying drawing explanation
The structural representation of the siphoning installation for the quantitative sample concentration of planktonic organism that Fig. 1 provides for the utility model.
Wherein, 1-sampling bottle, 2-bottle stopper or inner cap, 3-glass bend pipe, 4-woven hose, 5-flow controller.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
The structure of the siphoning installation for the quantitative sample concentration of planktonic organism provided by the invention as shown in Figure 1, comprises the woven hose 4 of the sampling bottle 1 of band inner cap or bottle stopper, glass bend pipe 3, plankton net and band flow controller 5.Glass bend pipe 3 is L-shaped glass bend pipe, and glass bend pipe 3 upper end is by calcination drawing-down, so that woven hose is communicated with.The centre of sampling bottle inner cap or bottle stopper 2 is provided with through hole, and the lower end of glass bend pipe 3 is arranged in sampling bottle through through hole.The diameter of through hole matches with the external diameter size of glass bend pipe bottom, and the diameter of through hole, slightly larger than the external diameter of glass bend pipe bottom, should make glass bend pipe move up and down easily, make glass bend pipe play the effect of sealing again.The upper end of glass bend pipe 3 is inserted in the infusion tube of woven hose, and glass bend pipe and woven hose form the siphon passage of U-shaped.Plankton net has layer 2-3 screen cloth, plankton net transparent adhesive tape is fixed on the port of glass bend pipe lower end, the network interface of plankton net all wraps on the outer wall of glass bend infratubal port, prevents planktonic loss in siphonic process, and the specification of plankton net is 25#.
