Abstract
The utility model relates to the field of biology, in particular to a phytoplankton counting device and system. The phytoplankton counting device comprises a glass slide, a cover glass and a circumferentially-closed pad arranged between the glass slide and the cover glass. A groove is formed by the glass slide and the pad and is used for accommodating water to be detected. According to the phytoplankton counting device and system, the pad is arranged between the glass slide and the cover glass to allow the groove to form between the pad and the glass slide; compared with the prior art, the phytoplankton counting device and system has the advantages that the groove is capable of carrying more water, namely increasing the volume of the water to be detected, and the deviation on counting phytoplankton in the water is reduced.
Description
Technical field
The utility model relates to biological field, in particular to counting assembly and the system of phytoplankton.
Background technology
Phytoplankton is the indicator organism of measuring water quality.The water quality in a slice waters how, has inseparable relation with the degree of enriching and the group's composition of phytoplankton, and the minimizing of phytoplankton or excessive multiplication, will indicate that sheet waters is just tending to worsen.
In practical study process, people need to adopt the water in waters to detect, and the quantity of the phytoplankton in the water in unit of account volume, to determine the water quality in this sheet waters.The counting assembly of the phytoplankton adopting in correlation technique comprises microslide and cover glass, conventionally the water of getting 0.25 milliliter or 0.5 milliliter detects, the water that comprises phytoplankton is directly placed on microslide, the water that attractive force between hydrone makes to be placed on microslide can not scatter immediately, then cover glass is placed in waterborne, the water that is opposite on microslide of recycling microscope is observed, and by mobile microslide all around, records the phytoplankton quantity in the visual field.
The mode that adopts above-mentioned microslide to coordinate with cover glass is filled with water, utilizing microscope to obtain the quantity of phytoplankton, owing to directly water being placed on microslide, make the small volume of the water under can containing, and phytoplankton skewness in water, there is deviation in the counting of phytoplankton therefore.
Utility model content
The purpose of this utility model is to provide counting assembly and the system of phytoplankton, to solve the above problems.
The counting assembly of a kind of phytoplankton is provided in embodiment of the present utility model, the counting assembly of this phytoplankton comprise microslide, cover glass and be arranged on microslide and cover glass between the backing plate of circumferential sealing; The groove that backing plate and microslide form, groove is for placing water to be detected.
Preferably, be provided with many separator bars on microslide, microslide is divided into the region that multiple areas are identical by many separator bars.
Preferably, gluing between backing plate and microslide.
Preferably, the xsect of microslide and groove is rectangle.
The number system that a kind of phytoplankton is also provided in embodiment of the present utility model, this system comprises the counting assembly of microscope and phytoplankton as above, the counting assembly of phytoplankton is placed on microscopical objective table.
The counting assembly of the phytoplankton of the utility model above-described embodiment and system, by backing plate being set between microslide and cover glass, make to form groove between backing plate and microslide, relatively and prior art, this groove can take up more water, increase the volume of water to be detected, reduce the deviation to hydroplankton counting.

Description of reference numerals:
Microslide-1; Cover glass-2; Backing plate-3; Groove-4; Separator bar-5.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
In conjunction with Fig. 1-Fig. 3, the counting assembly of a kind of phytoplankton is provided in embodiment of the present utility model, the counting assembly of this phytoplankton comprise microslide 1, cover glass 2 and be arranged on microslide 1 and cover glass 2 between the backing plate 3 of circumferential sealing; The groove 4 that backing plate 3 and microslide 1 form, groove 4 is for placing water to be detected.
Particularly, microslide 1 and cover glass 2 all can adopt microslide 1 of the prior art and cover glass 2, can also use other parts that can realize identical function to replace.The circumferential sealing of backing plate 3, alternatively, backing plate 3 can be a glass plate that is provided with through hole, can also be in the middle of other, to be provided with groove, the circumferentially structure of sealing, the backing plate 3 circumferentially sealing has formed one with the surface of the close backing plate 3 of microslide 1 can be for placing the groove 4 of water to be detected, directly water to be detected is placed on microslide 1 with respect to prior art, can the splendid attire more water to be detected of the counting assembly of the phytoplankton that the utility model provides, the thickness of backing plate 3 has determined the depth of groove 4, and microslide 1 is as the bottom land of groove 4.
The counting assembly of the phytoplankton of the utility model above-described embodiment and system, by backing plate 3 being set between microslide 1 and cover glass 2, make to form groove 4 between backing plate 3 and microslide 1, relatively and prior art, this groove 4 can take up more water, increase the volume of water to be detected, reduce the deviation to hydroplankton counting.
Preferably, be provided with many separator bars 5 on microslide 1, microslide 1 is divided into the region that multiple areas are identical by many separator bars 5.
In specific implementation process, can also on microslide 1, be provided with many separator bars 5, wherein the two ends of separator bar 5 are arranged on two ends relative on microslide 1, and separator bar 5 can all be arranged in parallel, and it can also be longitudinal being specifically as follows horizontal; Separator bar 5 can also be crisscross setting, and microslide 1 has been divided into the region that multiple areas are identical by many separator bars 5.The fin that separator bar 5 can be arranged on microslide 1 can also be groove, does not limit at this.
In actual application, when examining under a microscope, experimenter can count one by one taking unit area as unit, the mode of having avoided available technology adopting to have no the art of composition moves counting, the microslide 1 of what the utility model provided be provided with separator bar 5 is more easily counted the phytoplankton being positioned in the water to be detected on microslide 1, and the accuracy rate of counting is higher.
Preferably, gluing between backing plate 3 and microslide 1.
In actual application, backing plate 3 and microslide 1 are cohered, make backing plate 3 cannot depart from microslide 1, make one-piece construction more firm.
Preferably, the xsect of microslide 1 and groove 4 is rectangle.
Adopting rectangular microslide 1 and xsect is that rectangular groove 4 coordinates, and makes its broad view, is convenient to arrange separator bar 5 on microslide 1.The counting assembly of the phytoplankton that the utility model provides is simple in structure, is easy to make, and practical.
The number system that a kind of phytoplankton is also provided in embodiment of the present utility model, this system comprises the counting assembly of microscope and phytoplankton as above, the counting assembly of phytoplankton is placed on microscopical objective table.
