Description
Technical field
The utility model cuvette technical field, particularly a kind of easy spectrophotometer suction-spitting-type cuvette.
Background technology
The cuvette of spectrophotometer is currently used for, is usually quartz or glass material, cuboid, without any auxiliary knot
The container of structure.Before determining sample liquid, it is necessary to which at least three times, it is as follows that general sample liquid loads step to manual rinse cuvette：Test sample will be treated
Poured out after liquid injection cuvette, at least repeatedly for three times, after last time injects sample liquid, cuvette is carefully wiped with blotting paper and is dried in the air
It is dry, photometer sample room door insertion spectrophotometer specimen holder is then opened, sample room door is closed, carries out sample liquid test.This behaviour
Make process, frequently wipe cuvette, and frequently inserted from photometer specimen holder and extract cuvette out, easily cause cuvette and wipe not
Clean or abrasion causes larger test error.When sample size is more, wiping process needs substantial amounts of blotting paper, does not meet green
Environmental requirement, while whole process is also more time-consuming.
Prior art, a kind of injector structure (number of patent application of spectrophotometer：200810041869.5), the technology
Peristaltic pump and hand-held injector are mainly configured to photometer and carries out related circuit repacking, to complete sample introduction process, cost
With technical difficulty height.Need to reequip photometer, it is necessary to be equipped with high precision peristaltic pump, cost is higher；Since it is desired that to existing
There is photometer to be transformed, so technical difficulty is larger, it is necessary to ask professional and technical personnel to pacify for Most users
Dress, it is big to promote difficulty.
Utility model content
The purpose of this utility model is to provide a kind of structure-improved of cuvette, avoids every time manual wiping cuvette clean
Degree is inconsistent, caused test error and cuvette abrasion, and avoids a large amount of uses of blotting paper.Avoid being repeatedly opened,
Sample room door is closed, taken out repeatedly, be put into cuvette and the action such as be sampled, clean, so as to reduce sample introduction operating procedure, raising
Operating efficiency.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of easy spectrophotometer suction-spitting-type cuvette, including cuvette body, the chamber of described cuvette body
Body connects pressure air intake duct, feed tube, discharging tube respectively, and described pressure air intake duct, feed tube are separately mounted on cuvette body
Portion both sides, described discharging tube lower end extend into the bottom of cuvette body cavity；Set respectively on described feed tube, discharging tube
It is equipped with feed liquor tube valve, discharge opeing tube valve.
A kind of easy spectrophotometer suction-spitting-type cuvette provided by the utility model, the technique effect having have：
1st, avoid every time the manual cuvette clean level that wipes inconsistent, caused test error and cuvette abrasion, and
Avoid a large amount of uses of blotting paper.
2nd, avoid being repeatedly opened, close sample room door and taken out from cell rack, be put into cuvette and be sampled, clean
Action, so as to reduce sample introduction operating procedure.
3rd, solve under manual "-air-breathing of calming the anger " device (such as liquid-transfering gun, syringe), the injection of contrastive colours ware and discharge
The continuous operation of liquid.
4th, high precision peristaltic pump and photometer repacking need not be equipped with, can be achieved with injecting sample liquid, discharge sample liquid process, significantly
Reduce cost.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model；
Fig. 2 is overlooking the structure diagram of the present utility model.
Embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
As depicted in figs. 1 and 2, a kind of easy spectrophotometer suction-spitting-type cuvette, including cuvette body 2, it is described
Cuvette body 2 cavity connect respectively pressure air intake duct 1, feed tube 3, discharging tube 5, described pressure air intake duct 1, feed tube 3
The top both sides of cuvette body 2 are separately mounted to, the described lower end of discharging tube 5 extend into the bottom of the cavity of cuvette body 2；Institute
Feed liquor tube valve 4, discharge opeing tube valve 6 are respectively arranged with the feed tube 3 stated, discharging tube 5.
Pressure air intake duct 1 is used to connect "-air-breathing of calming the anger " device, such as liquid-transfering gun, syringe, and pressure air intake duct 1 other end connects
The logical cavity of cuvette body 2, press the tube hub point of air intake duct 1 and the top of cuvette body 2, side distance respectively 4.5mm,
5mm；Its lower end of feed tube 3 is opening, and central point is 8mm, 8mm with the base of cuvette body 2, the vertical range of side；Feed liquor
The upper end of pipe 3 is internal orifice, the cavity of connection cuvette body 2, and it is open central point and the top of cuvette body 2, side respectively apart
8.7mm、1.3mm；The upper end open central point of discharging tube 5 and the vertical range of the top of cuvette body 2 are 10mm；Under discharging tube 5
In the cavity of end insertion cuvette body 2, lower end and the cavity bottom ultimate range of cuvette body 2 are 1mm.
Operation principle：
First by flexible pipe, allow pressure air intake duct 1 to connect "-air-breathing of calming the anger " device, and allow feed tube 3 to connect dress and treat test sample
The vessel of liquid, discharging tube 5 connect waste liquid cup.
When certain "-air-breathing of calming the anger " device is by pressing 1 air-breathing of air intake duct, under airflow function, feed liquor tube valve 4 is opened
And discharge opeing tube valve 6 is closed, sample liquids are sucked in the cavity of cuvette body 2 by feed tube 3, and then "-air-breathing of calming the anger " fills
Put air by pressing air intake duct 1 to be pressed into the cavity of cuvette body 2, under flow action, feed liquor tube valve 4 is closed and discharging tube
Valve 6 is opened, and sample liquids are discharged by discharging tube 5 from the cavity of cuvette body 2, so as to complete cuvette to each sample
Sample introduction and the rinse for telling sample or contrastive colours ware.
The technology contrastive colours ware is improved in itself, and technology finished product is made, and user can be as using conventional colorimetric ware one
Sample is easy to spread using our technical products, and the advantages of also possess prior art one：For example, avoid using manually from point
Light photometer is repeatedly opened sample room door, taken out cumbersomely from cell rack, be put into cuvette be sampled, clean etc. it is dynamic
Make.In addition, sample introduction process is without electricity consumption, it is more environmentally friendly.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
The scope of protection of the utility model is also should be regarded as with retouching.
