Unstable temperature exerts certain impact over the measurement for the optical rotation of optical rotary substance. The utility model , which is intended to resolve the constant temperature control problem of the test sample tube of polarization device, comprises two trough shape pipes; the section of the trough shape pipes is configured with falcate or U shape; an interface is respectively arranged at two ends of each trough shape pipe and the interfaces are communicated with each other via a trough shape pipe; an interface of one through shape pipe is communicated with an interface of another trough shape pipe via a soft pipe; the trough shape pipe and the interface are all made of metallic materials. The utility model can be installed fast on the test sample tube of polarization device and can be removed fast under the condition of no strict requirement for constant temperature.
Description
Technical field
The utility model relates to a kind of two-sectional type constant temperature jacket device that is used for the polarimeter coupon, belongs to optical instrument field.
Background technology
Polarimeter is optical activity direction and the big or small instrument that is used to measure optical active substance, according to concentration, the purity that the direction and the size of optical activity can be determined this substance solution, also can be used as the important evidence of the molecular structure of judging organic substance.The optical activity of optical active substance depends primarily on the structure of material itself.In addition, also see through the thickness of material with light, used light wavelength is relevant with temperature during measurement.When measuring regularly at temperature, wavelength and solvent one, various specific rotatory powers with optically active substance are certain value, thereby can be used for observing the optical activity of these materials, can also observe the process of reaction by the variation of observing system under test (SUT) optical activity in course of reaction.In the middle of this, temperature is very big to the influence of optical activity, and therefore many experimental projects all need carry out under certain constant temperature.Temperature variation can make polarization tube change length because of expanding with heat and contract with cold, and causes the density of testing liquid to change.In addition, temperature variation also may make and take place between the test substance molecule to associate or disassociation, and optical activity is changed.
The Zhao Xiuzhen of DaLian, China university chemistry and department of chemistry engineering is published in the article " improvement of polarimeter sample hose " on " university chemistry " 1999 03 phases, and, the Li Dahui of Tongren teachers training school department of biochemistry is published in the article " for polarimeter install thermostatic water-jacket " of the pedagogical higher junior college of Tongren on journal 02 phase of calendar year 2001 and has proposed two kinds of constant temperature polarization tube schemes that thermostatic water-jacket is installed regularly respectively, for constant temperature observation and the alternating temperature observation problem of tackling optical activity provides useful solution route.The constant temperature polarization tube that proposes in above-mentioned two literary compositions is to be non-removable fixing form.
The utility model content
Technical problem to be solved in the utility model is that a kind of thermostat that is used for the polarimeter coupon that can dismantle easily is provided.This thermostat is Fast Installation on the polarimeter coupon according to actual needs, also can needn't under the situation of strict constant temperature thermostat removed fast.
The utility model solve the technical problem by following scheme, the device that this scheme provides is a kind of two-sectional type constant temperature jacket device that is used for the polarimeter coupon, it is characterized in that, this two-sectional type constant temperature jacket device comprises two channel pipes, the transversal section of described channel pipe is falcate or U-shaped, on the two ends of each channel pipe an interface is arranged respectively, and, the interface that lays respectively on the channel pipe two ends passes through channel pipe UNICOM each other, and, an interface of each channel pipe and an interface of another channel pipe are by flexible pipe UNICOM, and the material that constitutes described channel pipe and described interface is a metal material.Interface on the two ends of channel pipe is to be used for the interface that isothermal liquid flows to or flows out.Described metal material is for example: copper, stainless steel.Described flexible pipe is for example: rubber tube, plastic tube, metal hose.Described channel pipe is the pipeline that the transversal section of hollow is falcate or U-shaped.Described two-sectional type constant temperature jacket device can also comprise some extension assemblies, described extension assembly is super constant temperature trough and two extension hoses for example, two interfaces of described two channel pipe remainders can be respectively and two end UNICOMs of extending hoses, two other ends that extend hoses respectively with the thermostatted water import and the outlet UNICOM of super constant temperature trough.Described two channel pipes are buckled on the polarimeter coupon involutoryly, form two lobe formula constant temperature jackets, connect thermostatted water, can carry out the optical activity surveying work of temperature constant at assigned temperature.
The beneficial effects of the utility model are that this two-sectional type constant temperature jacket device is Fast Installation on the polarimeter coupon according to actual needs, also can needn't under the situation of strict constant temperature two-sectional type constant temperature jacket device removed fast.
Description of drawings
Fig. 1 is the synoptic diagram of the pattern of polarimeter coupon common in the common laboratory.
Fig. 2 is the embodiment synoptic diagram of two-sectional type constant temperature jacket device described in the utility model.
Among the figure, the 1, the 2nd, channel pipe, the 3,4,5, the 6th, be used for the interface that isothermal liquid flows to or flows out, the 7th, the flexible pipe that channel pipe 1 and channel pipe 2 UNICOMs are got up, the 8, the 9th, described extension hose.
Embodiment
In embodiment illustrated in fig. 2, interface 3 connects via channel pipe 2 mutually with interface 4, interface 5 connects via channel pipe 1 mutually with interface 6, the interface 5 of channel pipe 1 and the interface 3 of channel pipe 2 are via flexible pipe 7 mutual UNICOMs, the interface 6 of channel pipe 1 and extension hose 8 UNICOMs, the interface 4 of channel pipe 2 and extension hose 9 UNICOMs, extend the other end of hose 8 and the thermostatted water water delivering orifice UNICOM of super constant temperature trough, extend the other end of hose 9 and the thermostatted water water inlet UNICOM of super constant temperature trough, the arrow among the figure represents that thermostatted water flows to.The length dimension of channel pipe 1 and channel pipe 2 is slightly shorter than the length dimension of the small diameter part branch of polarimeter coupon shown in Figure 1, so that embed wherein when installing, the tubular cavity that channel pipe 1 and channel pipe 2 involutory backs form are just in time agreed with the small diameter part branch of polarimeter coupon shown in Figure 1.
