Abstract
The utility model discloses a kind of flow cells for environmental protection tests, including pond body (1) and the hollow cavity (2) being located in pond body (1), the upper and lower of pond body (1) is respectively equipped with the interface conduit (3) being connected with hollow cavity (2), it is characterized by: the both ends that the hollow cavity (2) is connected with interface conduit (3) are groove (4), and the bottom of groove (4) is connected with interface conduit (3).The flow cell of the utility model is designed as groove shapes using two end faces of hollow cavity structure and hollow cavity, the upper and lower ends of hollow cavity are connect using isometrical interface conduit with the external world, guarantee that liquid can be full of entire pond body when sample introduction, flow cell sample flow when sucking discharge is smooth, noresidue, pollutes less, does not generate bubble, and it can effectively solve the problem that detection of the signal compared with weak sample, exclusive PCR detection avoids the interference from background, therefore is suitable for promoting the use of.
Description
Technical field
The utility model relates to technical field of fluid detection, when specifically a kind of sucking is discharged sample flow it is smooth,
Noresidue, pollution do not generate bubble less, and can effectively solve the problem that the circulation for environmental protection tests of detection of the signal compared with weak sample
Pond.
Background technique
Flow cell is a transparent pond, for liquid sample flow and is detected, and detector is mounted on flow cell,
The effect of flow cell is exactly that the liquid to be examined is allowed constantly to flow through wherein when detection, and detector, which constantly detects, flows through liquid
The signal intensity of body.Existing flow cell is in use, due to poor sealing, when for detecting readily volatilized fluid sample
It will lead to the inaccuracy of testing result, and liquid rudimentary horn easy to form.
Summary of the invention
The purpose of this utility model is that in view of the problems of the existing technology, sample flow is suitable when providing a kind of sucking discharge
Freely, noresidue, pollution do not generate bubble less, and can effectively solve the problem that the stream for environmental protection tests of detection of the signal compared with weak sample
Logical pond.
The purpose of this utility model solves by the following technical programs:
A kind of flow cell for environmental protection tests, including pond body and be located at the intracorporal hollow cavity in pond, the upper and lower of pond body
It is respectively equipped with the interface conduit being connected with hollow cavity, it is characterised in that: what the hollow cavity was connected with interface conduit
Both ends are groove, and the bottom of groove is connected with interface conduit.
The bottom section product of the groove is less than the sectional area of hollow cavity.
Four inner walls of the groove are all inclined-plane.
The tilt angle of four inner walls of the groove is 10 °~30 °.
The roughness of the inner wall of the hollow cavity is not higher than 0.025.
The pond body Seal Design and interface conduit specification for being located at pond body upper and lower is identical.
The utility model has the following advantages compared with prior art:
The flow cell of the utility model uses hollow cavity structure, and pond body is composed a cuboid by six sheet glass,
Two end faces of hollow cavity are designed as groove, and the tilt angle of each inner wall of groove is 10 °~30 °, and the two of hollow cavity
End connect using isometrical interface conduit with extraneous, passes in and out the upper and lower ends that sample is located at hollow cavity, guarantee liquid energy when sample introduction
It is enough full of entire pond body, three-dimensional Pool body design is sealed and is conducive to the detection for being easy the fluid sample of performance, not will form liquid
Rudimentary horn, flow cell sample flow when sucking discharge is smooth, noresidue, pollutes less, does not generate bubble, and can effectively solve the problem that
Signal compared with weak sample detection, exclusive PCR detection, avoid the interference from background；The inner wall roughness of flow cell is not high simultaneously
It in 0.025, is readily cleaned, so that sample introduction process is simple and quick and reduces the cross contamination of sample, therefore is suitable for promoting the use of.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the flow cell for environmental protection tests of the utility model.
Wherein: 1-pond body；2-hollow cavities；3-interface conduits；4-grooves.
Specific embodiment
The utility model is further described with embodiment with reference to the accompanying drawing.
A kind of flow cell for environmental protection tests as shown in Figure 1:, the hollow cavity 2 including pond body 1 and in pond body 1,
The upper and lower of pond body 1 is respectively equipped with the interface conduit 3 being connected with hollow cavity 2,1 Seal Design of pond body and is located in pond body 1
3 specification of interface conduit of lower section is identical；Both ends that the hollow cavity 2 is connected with interface conduit 3 are groove 4, and groove 4
Bottom is connected with interface conduit 3, and the bottom section product of the groove 4 is less than the sectional area of hollow cavity 2 and four inner walls of groove 4
Face is all inclined-plane, and the tilt angle of four inner walls of groove 4 is 10 °~30 °.In addition to the structure of groove 4 shown in FIG. 1, groove 4
It can also be designed as funnel-form, the inner wall of groove 4 is inclined arc surface at this time；It in addition is to avoid sample cross contamination, be convenient for
The roughness of cleaning, the inner wall of the hollow cavity 2 is not higher than 0.025.
The flow cell of the utility model use 2 structure of hollow cavity, pond body 1 by six sheet glass be composed one it is rectangular
Body, two end faces of hollow cavity 2 are designed as groove 4, and the tilt angle of each inner wall of groove 4 is 10 °~30 °, hollow cavity
The both ends of body 2 are connect using isometrical interface conduit 3 with extraneous, pass in and out the upper and lower ends that sample is located at hollow cavity 2, and when sample introduction protects
Entire pond body can be full of by demonstrate,proving liquid, sealed three-dimensional pond body 1 and designed the detection for being conducive to be easy the fluid sample of performance, will not
Liquid rudimentary horn is formed, flow cell sample flow when sucking discharge is smooth, noresidue, pollutes less, does not generate bubble, and can
Effective address signal compared with weak sample detection, exclusive PCR detection, avoid the interference from background；The inner wall of flow cell is thick simultaneously
Rugosity is not higher than 0.025, is readily cleaned, so that sample introduction process is simple and quick and reduces the cross contamination of sample, therefore is suitable for pushing away
It is wide to use.
Above embodiments are only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
