The utility model discloses a liquid that the district's absorption that absorbs water is outflowed protects through elasticity lag contrastive colours ware body outer wall to guarantee the luminousness of cell surface, reduce the loss of cleaning material and cell. The utility model has the advantages of simple structure, preparation convenience, convenient operation, improvement work efficiency, labour saving and time saving, save material, improvement measurement accuracy, environmental protection cleanness.
Description
Technical field
The utility model belongs to experimental apparatus technical field, particularly relates to the anti-pollution cuvette of a kind of novel convenient precision.
Background technology
Spectrophotometer is one of instrument the most frequently used in physico-chemical analysis, uses field very wide.In spectrophotometric use or calibrating, the accuracy of transmittance (absorbance) is the important indicator weighing instrument serviceability, and its order of accuarcy is directly connected to credibility and the science of surveyed data.So improve using and examine and determine accuracy and seeming particularly important of this index.Spectrophotometer is as a kind of exact instrument, and due to working environment in the operation course of work, the various reasons such as method of operating, some change will inevitably occur its technology status, may affect the performance of equipment, even bring out equipment failure and accident.Therefore, the necessary Timeliness coverage of present stage analytical work person and these hidden danger of eliminating, to the normal operation of the fault on-call maintenance guarantee instrument and equipment produced.Spectrophotometer is a kind of high resistant instrument, so be afraid of moist, too high air humidity will affect the stability of instrument and electric security, simultaneously, cuvette in using also is vulnerable to the pollution of liquid, its matching can be deteriorated, and should note preventing cell to be subject to contact and the corrosion of liquid in therefore using.So will clean in time after discovery matching is deteriorated, with serious pollution potassium dichromate washing lotion cleaning.When the difference of two cuvettes its transmittance when examining and determine matching being less than 0.5% transmitance, will considering again supporting or changing cuvette.In present stage spectrophotometer use procedure, cuvette will constantly take out and put into from cell, and pours and pour out the liquid and cleaning fluid that need colorimetric into, and must be wiped by water mark with clean soft gauze.But carry out colorimetric according to above-mentioned traditional flow process, with in gauze wiping process, light face is vulnerable to wearing and tearing thus affects transmitance, and cannot reduce under the scouring number of times prerequisite to light face, surface smoothness is destroyed, and affects the transmittance of cuvette.If the cuvette often more renewed, then the wasting of resources can be caused.In addition, cell is easy contaminated corrosion thus also, not only loaded down with trivial details through conventional gauze wiping, and can cause the wasting of resources of gauze.
Summary of the invention
The utility model object is the defect for prior art, provides a kind of novel convenient precision anti-pollution cuvette.
The utility model for achieving the above object, adopts following technical scheme:
A kind of anti-pollution cuvette, comprises cuvette body, it is characterized in that: described cuvette body oral area outer wall is disposed with zone of transition, suction zones, clamp area and spring protective cover downwards; Described zone of transition parcel cuvette body oral area, connects to the transition of periphery, suction zones for cuvette body oral area; Described suction zones is used for the liquid that absorption cuvette body oral area flows out; Described clamp area is used for clamping, is affectedly bashful cuvette body; Described spring protective cover bottom not with cuvette body outer wall lower contacts, by cell extruding post shrinkage.
It is further characterized in that: described suction zones and clamp area are cylindrical, between insulating course is set; Described zone of transition connects round structure for square.
Further: described zone of transition, suction zones, clamp area and spring protective cover are demountable structure.
Preferred: described spring protective cover is train of dress shape, selects water proof, resistant material.
Described spring protective cover surface is provided with parallel annular fold.
The utility model arranges zone of transition, suction zones, clamp area and spring protective cover at cuvette body oral area outer wall, the liquid of outflow is absorbed by suction zones, protected by spring protective cover contrast colors ware body outer wall, thus reduce the wash number of cuvette outside surface, ensure the transmittance of cuvette outside surface, reduce the loss of cleaning material and cuvette.The utility model have structure simple, easy to make, easy to operate, increase work efficiency, time saving and energy saving, save material, improve measuring accuracy, environment-protecting clean advantage.

Fig. 2 is the utility model using state schematic diagram.
Embodiment
An anti-pollution cuvette as shown in Figure 1, 2, comprises cuvette body 1, and described cuvette body 1 oral area outer wall is disposed with zone of transition 2, suction zones 3, clamp area 4 and spring protective cover 5 downwards.Described suction zones 3 and clamp area 4 are cylindrical, between insulating course is set; Described zone of transition 2 connects round structure for square.Described spring protective cover 5 is train of dress shape, and surface is provided with parallel annular fold, selects water proof, resistant material.
Described zone of transition 2 wraps up cuvette body oral area, connects to the transition of periphery, suction zones 3 for cuvette body 1 oral area; Adopt the material that also can not be corroded that do not absorb water.The liquid that described suction zones 3 is flowed out for absorption cuvette body 1 oral area; Select the material of corrosion-resistant, easy water suction.Suction zones 3 intercepts cuvette mouth and cylinder clamp area 4, ensures that ware oral fluid body flows down in process and is absorbed in time, is not down infected with cuvette body 1 inferior portion.Described clamp area 4 is for clamping, being affectedly bashful cuvette body 1; Select resistant material, conveniently pinch.Described zone of transition 2, suction zones 3, clamp area 4 and spring protective cover 5 are demountable structure.Described spring protective overlap 5 bottoms not with cuvette body 1 outer wall lower contacts, extrude post shrinkage by cell 6.When cuvette body 1 tilts, spring protective cover 5 can not encounter cuvette body 1 lower zone.
When starting working, pinching cuvette body 1 is placed in outside cell 6, pour required colorimetric liquid into, now spring protective cover 5 is in extended configuration, wraps whole cuvette body 1 comprehensively, and the external world is water stain, liquid can not be infected with cuvette body 1, if top cuvette body 1 oral area has liquid to spill simultaneously, can be absorbed by cylinder suction zones 3, also can not be infected with cuvette body 1, save with clean gauze wiping process.Put into cell 6, spring protective cover 5 is by cell 6 upper compressive, and in compressive state, cuvette body 1 main body enters in cell 6 and carries out colorimetric simultaneously.Cell 6 is taken out cuvette body 1 in the cylinder clamp area 4 pinching or clamp on cuvette body, spring protective cover 5 stretches naturally, cover whole cuvette body 1, topple over the liquid that colorimetric crosses to clean, there is the inclination (be 0-90 ° with horizontal sextant angle) of certain angle in cuvette body 1, can not touch between spring protective cover 5 and cuvette body 1 external wall beneath.Clean and completely to dry, when laying up, disassemble each parts, keep each several part well in seal box.If needed, cylinder suction zones parts and spring protective cover parts can be washed separately or change.From start to finish, any friction and water stain contamination are not received in the light face of quartz colorimetric utensil body, and light is as new.
