Abstract
The utility model relates to a reaction cup. The reaction cup is characterized in that a sealing film is fixed at a cup hole of the reaction cup. According to the reaction cup, as a layer of sealing film is arranged at the cup hole of the reaction cup, the pre-subpackaging of a dilution liquid is realized; as an inner layer of the sealing film and the reaction cup are made of same materials, the sealing film and the reaction cup can be easily welded and separated and are very tightly welded without leaking the dilution liquid; the sealing film and the reaction cup are easily separated from each other, and the sealing film can be easily and completely removed from the cup hole of the reaction cup, so that the plugging fitting between the reaction cup and an integrated quantitative sampling filler cannot be influenced.
Description
Technical field
The utility model relates to a kind of reaction cup.
Background technology
Reaction cup is widely used in biology, chemistry, medical science testing process, in turbidimetry detects, for the turbid analyzer of match ratio, uses.Because turbidimetric analysis has a wide range of applications, for some ripe test items, developed integrated quantitative sampling charging point, complete quick sampling and reagent adding process, in use the sampling head after sampling is inserted the reaction cup of dilution is housed, then the reagent in charging point is squeezed in reaction cup.Way is that a large amount of dilutions is written in a container widely at present.When testing, dilution is added in reaction cup and tested, not only waste resource, and extended the operating time.
Although before dispatching from the factory to reactant liquor in addition packing easily expect, but because the rim of a cup of reaction cup and the closure gasket groove of integrated sampling charging point need closely cooperate, if the sealing to reaction cup after packing is improper, or diaphragm seal complete opening easily, can directly affect the assembling of the two, this also becomes the principal element that conditioned response liquid divides process of assembling in advance.
Utility model content
The purpose of this utility model is to provide one can realize the pre-packing of dilution, simple in structure, easy to operate, diaphragm seal firm welding and be easy to the complete reaction cup with diaphragm seal of taking off.
In order to achieve the above object, the utility model adopts following technical scheme:
The rim of a cup place of reaction cup described in the utility model is fixed with diaphragm seal.
Further, diaphragm seal described in the utility model comprises skin and internal layer, and the material of described internal layer is identical with the material of reaction cup; Described skin is aluminium film or plastic foil.
Further, the material of reaction cup described in the utility model is cyclic olefine copolymer.
Further, the thickness of internal layer described in the utility model is 0.05 ~ 0.5 mm, and described outer field thickness is 0.05 ~ 0.5 mm.
Further, in reaction cup described in the utility model, be packaged with liquid.
The internal layer of described diaphragm seal refers to one deck that diaphragm seal contacts with reaction cup.
The skin of described diaphragm seal refers to and diaphragm seal and extraneous one deck contacting.
Described cyclic olefine copolymer refers to the copolymer of preparing as raw material take cyclopentadiene or cyclopentadiene derivant.
The beneficial effects of the utility model are:
The utility model is provided with one deck diaphragm seal at reaction rim of a cup place, has realized the pre-packing of dilution, and the internal layer of diaphragm seal is identical with the material of reaction cup, is easy to the welding of the two with separation, and the two welding is extremely tight, can not cause the leakage of dilution; The two is easily separated, and diaphragm seal can be from reaction cup rim of a cup complete taking off easily, can not affect reaction cup and coordinate with the grafting of integrated quantitative sampling charging point.
Reaction cup of the present utility model and diaphragm seal internal layer all adopt cyclic olefine copolymer as main component, and the cyclic olefine copolymer copolymer that to be a class prepare as raw material take cyclopentadiene or cyclopentadiene derivant, is a kind of amorphous thermoplastics; The plurality of advantages such as its prepared reaction cup has that transparency is high, glass transition temperature is high, birefringence is low, water imbibition is low, chemical resistance and high temperature resistant degree.
The utility model diaphragm seal is structure of composite membrane, and the thickness of its internal layer is 0.05 ~ 0.5 mm, and outer field thickness is 0.05 ~ 0.5 mm, and the two has good stickiness, when the thickness of film is during in this scope, can meet the demand of sealing; When the density of sealed up for safekeeping dilution is higher, need mate thicker diaphragm seal.

The specific embodiment
Embodiment 2
Embodiment 2 is at the reaction cup rim of a cup place of embodiment 1 welded seal film.As shown in Figure 3, described diaphragm seal 2 is lamination layer structure, and it comprises outer 2-1 and internal layer 2-2, and the material of described internal layer 2-2 is identical with the material of reaction cup 1; Described outer 2-1 is aluminium film or plastic foil.Reaction cup 1 adopts the welding of directly-heated technique with diaphragm seal 2.Implement, before the welding of directly-heated technique, dilution to be pre-installed in described reaction cup 1, then implement the welding of directly-heated technique, can obtain rim of a cup place as shown in attached Figure 4 and 5 and be provided with the reaction cup 1 of diaphragm seal 2, in reaction cup 1, be provided with the liquid of prepackage.The preparation technology of composite membrane described in the utility model and directly-heated welding procedure are process known in those skilled in the art.
The utility model is provided with one deck diaphragm seal at reaction rim of a cup place, has realized the pre-packing of dilution, and the internal layer of diaphragm seal is identical with the material of reaction cup, is easy to the welding of the two with separation, and the two welding is extremely tight, can not cause the leakage of dilution; The two is easily separated, and diaphragm seal can be from reaction cup rim of a cup complete taking off easily, can not affect reaction cup and coordinate with the grafting of integrated quantitative sampling charging point.
Reaction cup of the present utility model and diaphragm seal internal layer all adopt cyclic olefine copolymer as main component, and the cyclic olefine copolymer copolymer that to be a class prepare as raw material take cyclopentadiene or cyclopentadiene derivant, is a kind of amorphous thermoplastics; The plurality of advantages such as its prepared reaction cup has that transparency is high, glass transition temperature is high, birefringence is low, water imbibition is low, chemical resistance and high temperature resistant degree.
The utility model diaphragm seal is structure of composite membrane, and the thickness of its internal layer is 0.05 ~ 0.5 mm, and outer field thickness is 0.05 ~ 0.5 mm, and the two has good stickiness, when the thickness of film is during in this scope, can meet the demand of sealing; When the density of sealed up for safekeeping dilution is higher, need mate thicker diaphragm seal.
