Description
Technical field
The present invention discloses a kind of distilling apparatus, specifically, is a kind of water maker, belongs to chemical device glass apparatus technical field.
Background technology
In chemical experiment process, concentrated liquid and detected components adopt usually to be needed to use water maker.But the sealing of existing apparatus mainly adopts frosted sealing joint, but sealing property is poor, usually there is the problem of gas leakage, this creates certain impact to experimental result, even affects the accuracy of testing result, and especially in sulfur dioxide in food detects, this problem is more obvious.
Usually adopt williams' method in the detection of residual sulfur dioxide in food, its principle boils the SO2 disengaged in acid condition to be taken out of by inert carrier gas N2, absorbed and be oxidized to H2SO4 solution, then use the titration of NaOH standard liquid in absorption tube by H2O2 solution.Williams (Monier Williams) method is the fine method that sulfur dioxide in food detects, and is the detection method that the countries and regions such as U.S. FDA, Japan, Korea S, European Union, Taiwan are approved jointly.The national standard " mensuration of sulphite in foods " (GB/T5009.34-2003) that China's sulfur dioxide in food detects still has larger gap than Williams (Monier Williams) method, compares Williams (Monier Williams) method and has the following advantages: 1) can effectively get rid of the interference of sample matrices to testing result in pole with national examination criteria.First be that after the science of distilling apparatus structure makes distillation be vaporized into lease making condensation, the overwhelming majority returns the excellent feature of heating up in a steamer, can effectively get rid of the interference of sample matrices to testing result in pole.Next is the methyl red indicator instruction titration end-point that this method adopts color change interval PH4-5, and the organic matter can got rid of further in sample absorbs through distillation and is oxidized to the interference of organic acid to testing result.Due to this detection method have anti-interference, titration end-point clearly, can accurate testing result be obtained, thus the commodity coverage that is suitable for of this method is very wide, can contain all food and food agricultural produce.2) agents useful for same is few, only needs hydrogen peroxide, methyl red and NaOH titrand.3) reaction condition acid adding heating, fiercer, thus sample treatment is simple, as long as consider representativeness and the harmony of test specimen, can knock down distilling flask, sense cycle is short, from sample treatment to off-test, only need 3 hours.4) wide ranges of detected value, content of sulfur dioxide all can once be obtained a result from lower than 10ppm to up to 30000ppm.
But the interface of this its distilling apparatus of detection method is more, easily cause gas leakage to affect accuracy and the precision of testing result, even can cause the inaccurate of test result, this problem annoyings experimenter always.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of favorable sealing property, and convenient inspection and observation air-tightness, guarantee result of the test water maker accurately and reliably.
For solving the problems of the technologies described above, technical scheme provided by the invention is such: this water maker, comprise flask, the frosted interface of flask is plugged with condenser, the frosted interface of the condenser other end is plugged with delivery line, the other end of delivery line passes into absorption tube, and the frosted interface upper periphery of described flask and condenser is equipped with the container holding water, and condenser is plugged in the frosted interface of flask by the inside of container.
Above-mentioned a kind of water maker, described flask is there-necked flask, one of them frosted interface grafting condenser of there-necked flask, another frosted interface grafting separatory funnel of there-necked flask, the upper end of separatory funnel is plugged with joint of exerting pressure, also have a frosted interface to be plugged with gas introduction tube, the frosted interface of the other end of condenser is plugged with delivery line, and the other end of delivery line passes into absorption tube; Wherein, the periphery, upper end of each frosted interface of described there-necked flask is equipped with the container holding water, and the periphery, upper end of condenser is also provided with the container holding water; Condenser, separatory funnel and gas introduction tube are plugged in corresponding frosted interface respectively by internal tank, and delivery line is plugged in the frosted interface of condenser by internal tank.
Further, above-mentioned water maker, described frosted interface and container one-body molded
Further, above-mentioned water maker, described condenser is 8 ball alveolitoid condensers.
Further, upper described water maker, described absorption tube is spray bubble GAS ABSORPTION pipe.
Compared with prior art, distilling apparatus tool provided by the invention has the following advantages:
1, be provided with in the upper end of the frosted interface of flask and condenser pipe the container holding water, make it be formed by the assembly of water-pressure sealed in frosted interface and container, ensure the sealing of its junction;
If 2, this distilling apparatus gas leakage, has bubble to emerge, very intuitively, facilitates airtight test and observation in container; Both improve air-tightness, facilitate again bubble-tight inspection and observation;
3, this device air-tightness is good, when detecting content of sulfur dioxide especially for williams' method, no matter is reagent blank recovery of standard addition, or specimen test recovery of standard addition is all greatly improved, and usually reaches more than 95%; Under the representativeness and the good condition of harmony of test specimen, the reappearance of testing result is fabulous, and precision is high.
