Description
Technical field
The utility model belongs to the cuvette for carrying out optical measurement, and in particular to a kind of more light paths of double light path are salable
Cuvette.
Background technology
Cuvette, also known as absorption cell, sample cell, it is used for filling reference liquid, sample liquid, is matched with spectrometric instrument,
Quantitative, qualitative analysis is carried out to material, is widely used in chemical industry, metallurgy, medical treatment, medicine, food, environmental protection, power and water plants, stone
The industries such as oil, department and universities and colleges, R＆D institution's test, chemical examination use.
During using photometer measurement solution concentration, current all cuvettes only have a light path, general standard
Cuvette light path be 10 millimeters, it is some it is special in the case of its use be restricted.It is as multiple in having in a certain solution
The absorbance of component needs to measure, and each component is because its different absorbance of concentration or absorptivity has greatest differences, because
This can not be measured using current monochromatic light journey cuvette in same cuvette to its absorbance.
The existing generally open structure of cuvette, reagent can only be added in detection and measured.And measurement is volatile
Can measure inaccuracy during liquid caused by volatilization, and poisonous and harmful substances volatilization also result in pollution to detecting environment and
Injury to testing staff.Although jumping a queue cuvette in the prior art, most of presence can not seal, poorly sealed ask
Topic.
Traditional quartz colorimetric utensil, involves great expense, and is not suitable as the use of batch consumptive material.
Utility model content
The purpose of this utility model is to provide a kind of colorimetric for the more light paths of double light path that cost is relatively low, and large calibre threads seal
Ware structure, it can complete the data analysis of 10 millimeters of light paths, 6 millimeters of light paths in same cuvette so that measuring range and spirit
Sensitivity is more flexible, can carry out more optical detections, and considerably increase the sealing property of cuvette.
To achieve these goals, the sealable cuvette of the more light paths of a kind of double light path provided by the utility model, it is described
Cuvette includes cuvette body, internal thread lid, and the inlet welding of the cuvette body has with externally threaded pipe section, institute
The screw thread for being provided with internal thread lid and being engaged with pipe section external screw thread is stated, the cavity of the cuvette body is bottom fillet knot
Structure, top wide opening structure, the upper end of the bottom fillet structure is seamlessly transitted to the lower end of the top wide opening structure, under described
The width of portion's fillet structure inner chamber is 10 millimeters, thickness is 6 millimeters, the lumen thickness of the top wide opening structure is 10 millimeters,
Width is 10 millimeters.
Preferably, the pipe section diameter is more than 10 millimeters, completes large calibre threads sealing, and heavy caliber feed liquor is convenient.It is close
The good cuvette of envelope property can hold reagent for a long time.Traditional quartz colorimetric utensil involves great expense, and is not suitable for as consumptive material.This practicality is new
The cuvette body of type uses the makrolon or polystyrene material of low cost, and internal thread lid uses polypropylene material, can be into
For real consumptive material.
Preferably, there is sealing gasket in the internal thread lid.
The sealable cuvette of the more light paths of double light path provided by the utility model, has the advantages that：
Cuvette body uses polypropylene using cost relatively low makrolon or polystyrene material, internal thread lid
Material, sealed using large calibre threads, large calibre threads seal the sealing that can greatly improve cuvette, turn into cuvette
A kind of container for being more than using in the measurements, can also hold reagent for a long time.Detection reagent can be added to cuvette in advance
In.In measurement, user need to only add sample can direct measurement, eliminate the mistake with reagent and packing reagent
Journey, facilitate and simplify measuring process.Other cuvette uses different light path designs, double light design, it is possible to achieve two
Different light paths (10 millimeters of light paths and 6 millimeters of light paths), meets different optical detections.The invention of this cuvette is fast inspection neck
Important breakthrough in domain, make detection product more convenient, be more suitable for layman's use, it is easier to allow fast inspection product to enter
Individual all trades and professions, especially household product applications.
