Abstract
The utility model relates to a constant temperature device of a cuvette. The device comprises a slot in a structure which is in a shape like the Chinese character shan and consists of three sealed vertical tanks and a sealed transverse tank, wherein the three sealed vertical tanks are communicated with the sealed transverse tank inside; each sealed vertical tank is provided with a liquid inlet branch pipe which is connected with a liquid inlet main pipe while the other end of the liquid inlet main pipe is arranged in a constant temperature bath; the constant temperature bath is provided with an electric pump, the transverse tank is provided with a drainage pipe while the other end of the drainage pipe is connected to the constant temperature bath; the constant temperature bath is internally provided with a stirrer and a temperature controller. The temperature of a liquid is controlled constant by the constant temperature bath, and the liquid enters into the liquid inlet branch pipe, so that the constant temperature liquid quickly fills the slot and then enters into the constant temperature bath through the drainage pipe. During operation, the cuvette is placed in the slot, and the constant temperature liquid quickly circulates through the electric pump of the constant temperature liquid. The temperature of the circulating liquid is controlled constant through the temperature controller for the constant temperature bath, and the liquid in the constant temperature bath enters into the slot through the electric pump and quickly circulates, so that the temperature of liquid in the cuvette is quickly stabilized to an appointed temperature.
Description
technical field:
The utility model relates to chemical analysis Instrument technology field, refers in particular to a kind of cuvette thermostat.
background technology:
Spectrophotometric analysis experiment depends on chromogenic reaction more, and the most temperature influence of chromogenic reaction Activity and stabill, therefore the accuracy temperature influence of spectrophotometric analysis experiment is larger, in regular job, even measure under equivalent environment, also can cause the unstable of test data because seasonal variations room temperature is non-constant, conventional electrothermic constant temperature equipment often temperature control is not very accurate, and the square space of existing liquid constant temperature device is only applicable to single size cuvette, limit its usable range.
summary of the invention:
The purpose of this utility model is to provide a kind of cuvette thermostat, solves the larger problem of accuracy temperature influence of present spectrophotometric analysis experiment.
The purpose of this utility model realizes as follows: a kind of cuvette thermostat, comprise draw-in groove, it is characterized in that: the structure of the mountain shape that draw-in groove is made up of three vertical casees of sealing and horizontal case of sealing, and three vertical casees of sealing and a sealing horizontal case inside communicate, on the vertical case of each sealing, be equipped with feed liquor arm, feed liquor arm is connected on feed liquor supervisor, the feed liquor supervisor other end is located in thermostatic bath, thermostatic bath is provided with electric pump, horizontal case is provided with discharging tube, the other end of discharging tube is connected on thermostatic bath, thermostatic bath inside is provided with stirrer, temperature controller.
The beneficial effects of the utility model are: thermostatic bath guarantees that temperature control is accurate; Feed liquor arm can guarantee that in draw-in groove, colorimetric utensil temperature is constant fast, does not affect light path in mensuration, guarantees the accuracy of measuring; This device is suitable for spectrophotometric method experiment; Temperature is constant fast, and temperature control is accurate; Be applicable to multiple cuvette size, and do not cause light loss; Be applicable to using under various temperature condition heat-proof corrosion resistant erosion.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
embodiment:
With reference to Fig. 1, a kind of cuvette thermostat, comprise draw-in groove, it is characterized in that: the structure of the mountain shape that draw-in groove is made up of three vertical casees 3 of sealing and horizontal case 9 of sealing, and three vertical casees 3 of sealing and sealing horizontal case 9 inside communicate, on the vertical case 3 of each sealing, be equipped with feed liquor arm 1, feed liquor arm 1 is connected on feed liquor supervisor 2, feed liquor is responsible for 2 other ends and is located in thermostatic bath 6, thermostatic bath 6 is provided with electric pump 7, horizontal case 9 is provided with discharging tube 8, the other end of discharging tube 8 is connected on thermostatic bath 6, thermostatic bath 6 inside are provided with stirrer 5, temperature controller 4.
Principle of work is: regulate and control temperature constant through thermostatic bath 6, make isothermal liquid be full of fast draw-in groove by feed liquor arm 1, liquid enters thermostatic bath 6 by discharging tube 8 again, when operation, cuvette is put into draw-in groove, and isothermal liquid is by electric pump 7 Rapid Circulations of thermostatic bath 6; Thermostatic bath 6 is constant by thermostat controlled circulation liquid temp, by electric pump 7, the interior liquid of thermostatic bath 6 is entered in draw-in groove, and Rapid Circulation, makes the testing liquid temperature constant assigned temperature that arrives fast in cuvette.
Concrete operation step is:
The first step: the circulating fluid first wish being used packs in thermostatic bath 6, opens thermostat and stirrer 5, and uniform temperature is set;
Second step: open electric pump 7 after temperature constant, make the interior liquid of thermostatic bath 6 be responsible for 2 inflow feed liquor arms 1 by feed liquor and enter again in draw-in groove, be then discharged in thermostatic bath 6 liquid Rapid Circulation by discharging tube 8;
The 3rd step: cuvette is put into draw-in groove, after temperature is again constant, start to measure the absorbance of liquid in cuvette, complete measurement operation, if carry out the mensuration of multiple samples, can repeat the 3rd step operation;
The 4th step: after measurement has operated, close temperature controller 4 and the stirrer 5 of thermostatic bath 6, blocking-up inlet, electric pump 7 is by draw-in groove and feed liquor supervisor 2 and the interior liquid suction of feed liquor arm 1 sky, and circulation fluid is got back in thermostatic bath 6, closes electric pump 7, cuvette is taken off, clean complete operation.
