Description
Technical field
The present invention relates to a kind of reagent strips, the detection reagent item after improving more particularly, to a kind of CV value.
Background technique
Detection reagent item is to set side by side thereon to a kind of common tool of reagent detection, generally selection pp material at present
Multiple independent detection grid are equipped with, need to make reagent the monitoring analysis of various physicochemical properties, wherein having one is pair
Reagent makees the analysis of light transmittance, and the grid bed-plate dimension that light transmittance is detected at this in existing industry is usually the flat of 8mm x10mm
Face, referred to as light detection area, bottom wall thickness is most thin can only to accomplish 0.48mm, mainly by mold self structure in Shooting Technique
Limitation, if being arranged to bottom wall thickness, lower than 0.48mm, molten plastic filling can be problematic in injection moulding process.And light transmittance
Detection be naturally light detection area wall thickness it is the smaller the better, therefore how on the basis of selecting same material reduce light detection area
Wall thickness be a problem for perplexing this industry technical staff always.
Summary of the invention
In view of the above-mentioned problems, the present invention is intended to provide a kind of cv value improve after detection reagent item, to the light of existing structure
Detection zone improves, with the more preferably more accurately light transmittance of detection reagent.
The technical scheme is that the detection reagent item after a kind of cv value improvement, the ontology including strip, described
Body is provided with a series of independent detection lattice for being used for reagent storage and detecting its physical and chemical performance along its length, described
The detection lattice of ontology wherein one end end are that light transmittance detects lattice, and light transmittance detection lattice bottom surface includes rectangular light detection area
With the nonfunctional area being located on the outside of light detection area, the length and width dimensions in the light detection area are 3-5mm, the thickness in the light detection area
Degree be 0.25-0.3mm, the nonfunctional area with a thickness of 0.35-0.4mm.
Preferably, the outer profile of the nonfunctional area is rectangular, having a size of 8x10mm.
Preferably, the CV value in the light detection area is less than or equal to 5%.
The present invention improves the light detection area of existing structure, and the light transmittance detection lattice of original planar structure are designed to rank
The structure of tread forms light detection area and the nonfunctional area region Liang Kuai, this two pieces of regions are in injection moulding process respectively by two parts
Independent mold insert is connected to the injection molding and open mold that product is completed on mold, can make light detection by the improvement of this structure
Thickness and outer dimension are reduced for the wall thickness reduction in area to the light detection area of the relatively original thickness of 0.25-0.3mm, is matched simultaneously
The structure for closing nonfunctional area, can smoothly be molded and produce, so that the measurement of reagent light transmittance is more accurate.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the bottom view that transmitance detects lattice in the present invention；
Fig. 3 is cross-sectional view of the Fig. 2 along the direction A-A；
Wherein: 1-ontology；2-detection lattice；21-light transmittances detect lattice；3-light detection areas；4-nonfunctional areas.
Specific embodiment
With reference to the accompanying drawing, invention is further described in detail.
As shown in Figure 1 to Figure 3, the detection reagent item after a kind of cv value of transmitance of the present invention improves, the sheet including strip
Body 1, the ontology 1 are provided with a series of independent for reagent storage and detecting its physical and chemical performance along its length
Detect lattice 2, the detection lattice 2 of the ontology 1 wherein one end end are that light transmittance detects lattice 21, and the light transmittance detects 21 bottom surface of lattice
Including rectangular light detection area 3 and positioned at the nonfunctional area 4 in 3 outside of light detection area, the length and width dimensions in the light detection area 3 are
3-5mm, the light detection area 3 with a thickness of 0.25-0.3mm, the nonfunctional area 4 with a thickness of 0.35-0.4mm, it is described non-
The outer profile of functional areas 4 be it is rectangular, having a size of 8x10mm, the CV value in the light detection area 3 is less than or equal to 5%, can be with surrogate outside
The functional requirement of similar product.
The above is only better embodiment of the invention, not makes any form of restriction to invention, it is all according to
According to technical principle any simple modification, equivalent variations or modification made to the above embodiment of the invention, the present invention is still fallen within
In the range of technical solution.
