Description
Technical field
The utility model belongs to experimental apparatus field, more particularly, to a kind of band sealing piston cuvette.
Background technology
Cuvette is for holding the container of sample liquid or reference liquid when quantitative or qualitative analysis is carried out to material, is spectrum
The important accessory of analytical instrument, it is supporting to be placed in such as on spectrophotometer, blood linear protein analyzer and Particle Size Analyzer instrument,
Extensively using with the industry such as chemical industry, medical treatment, metallurgy, environmental protection, water power and oil, and the test assay of universities and colleges and scientific research institutions.
In existing technology, the sealing means of cuvette are relatively simple, and bottle stopper and bottle mouth position simply are arranged into coarse table
Face such as frosting etc., but generally chemical reagent carries volatility, and gap between bottle stopper and bottleneck be present, it is easy to
Chemical reagent is caused to be volatilized from gap location, it is also possible to cause sample liquid in cuvette to be denatured due to contact outside air.Tradition
Cuvette label need to be pasted onto on cuvette during multiple sample measure, and adhesive label cleaning is inconvenient, and heating water bath
When it is easy to fall off.
The content of the invention
The shortcomings that the purpose of this utility model is to overcome prior art, there is provided a kind of band sealing piston cuvette, can
Sealing effectiveness is improved, is easy to the stickup of label.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of band sealing piston cuvette, bag
Cuvette body and lid are included, the cuvette body upper end is fixedly installed the first extension tube attached and the second extension tube attached, institute successively
State the first extension tube attached to connect by transit joint with second extension tube attached, branch pipe is provided with second extension tube attached, it is described
Branch pipe is mutually provided with second extension tube attached and put, and graduation mark is provided with the cuvette body, and the lid is provided with flexible
Piston and piston knob, the telescopic piston are flexibly connected with the piston knob, and the telescopic piston is placed in described second
In extension tube attached, the lid is additionally provided with inner chamber, and the interior intracavitary is movably set with mark changeover panel and directive wheel, the mark
Changeover panel and the directive wheel are intermeshed, and an opening are additionally provided with the lid, the changeover panel that identifies is from the opening
Expose at place.
Further, using interference fit between the telescopic piston and second extension tube attached.
Further, the graduation mark is accurate graduation mark, and measurable range 10-90 milliliters, accuracy is 2 milliliters.
Further, the cuvette body is square structure.
The utility model has the advantages and positive effects of：Due to that using above-mentioned technical proposal, can be lived by rotating
Plug knob control piston reaches sealing effectiveness in the depth of extension tube attached, and the mark of cuvette is easy in the setting for identifying changeover panel
Know, without labelled in cuvette outer surface, as long as sticking mark paster on mark changeover panel can complete to identify, operate
Easy and easy cleaning；With easy to use, the advantages that good sealing effect.

Embodiment
The utility model is described further with reference to embodiment and accompanying drawing.
As shown in Figure 1 to Figure 3, the present embodiment provides a kind of band sealing piston cuvette, including cuvette body 3 and lid
1, cuvette body 3 is square structure.The upper end of cuvette body 3 is fixedly installed the first extension tube attached 8 and the second extension tube attached successively
6, the first extension tube attached 8 and the second extension tube attached 6 are connected by transit joint 7, are provided with branch pipe 2 in the second extension tube attached 6, branch pipe 2 with
The phase of second extension tube attached 6, which provides, puts, and is provided with graduation mark 9 on cuvette body 3, and graduation mark 9 is accurate graduation mark, measurable range
10-90 milliliters, accuracy are 2 milliliters.
Lid 1 is provided with telescopic piston 5 and piston knob 4, and telescopic piston 5 is flexibly connected with piston knob 4, telescopic piston
5 are placed in the second extension tube attached 6, and in order to ensure sealing effectiveness, interference fit is used between the extension tube attached 6 of telescopic piston 5 and second.
Lid 1 is additionally provided with inner chamber 11, and mark changeover panel 12 and directive wheel 10 are movably set with inner chamber 11, identifies changeover panel 12 and leads
To the intermeshing of wheel 10, an opening 14 is additionally provided with lid 1, mark changeover panel 12 exposes at opening 14.
The course of work of this example：During work, sample liquid or reference liquid are held in cuvette body 3, by telescopic piston 5
