Description
Technical field
The utility model relates to a kind of medical research experimental provision, particularly a kind of water-bath device that is used for the serum deactivation.
Background technology
In medical experiment research, the serum deactivation is necessary base work in the experiment such as histocyte cultivation.The deactivation purpose is in order to remove in the serum complement etc. to heat sensitive material, also the mycoplasma that may exist in the serum to be had deactivation simultaneously.The temperature of conventional deactivation suggestion is between 45 ℃ to 62 ℃, and the time is not then waited from 15 minutes by 60 minutes. and wherein the most frequently used gimmick is 56 ℃ of heat treatments 30 minutes.The existing water-bath device that is used for the serum deactivation adopts water-bath usually, and the volume of water-bath is bigger, and the heating and cooling time is longer.And often since the operator to test main threads more, inactivation time is difficult to accurate assurance, makes serum descend placement for a long time in higher temperature, give the growth factor that contains in the serum, vitamin, precious material such as amino acid brings negative effect, has reduced the ability of supportint cell growth.Influenced result of experiment to a certain extent.
Summary of the invention
The purpose of this utility model provides a kind ofly can accurately control the water-bath device that is used for the serum deactivation that bath temperature, operation are time saving and energy saving, guarantee the medical research reference value automatically,
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of water-bath device that is used for the serum deactivation comprises that one fills the water bath of heat transfer water and the switch board in the casing outside, and described water bath bottom is provided with heating element heater, and sidepiece is provided with temp probe; Heating element heater connects the main switch of switch board by water-proof cable, temp probe connects the temperature controller of switch board, the switch board main switch is controlled main switch to the heating element heater power on/off according to the temperature signal of temp probe by temperature controller, it is characterized in that, described heating element heater is arranged in the closed chamber that constitutes at the bottom of a Table vessel holder and the water bath, and uncovered vessel that fill thermostatted water are set on the Table vessel holder.
In the such scheme, also be provided with timer in the described switch board, temperature controller is carried out the power on/off action by this timer to heating element heater.Described Table vessel holder is made with copper or stainless steel material.Described heating element heater is a resistance wire.
The utility model has the advantages that heating element heater is arranged in the closed chamber that constitutes at the bottom of a Table vessel holder and the water bath, and heating element heater is not directly contacted with heat transfer water, prevent that fouling from prolonging the service life of heating element heater.Heating element heater energising back heating, after by Table vessel holder heat being delivered to heat transfer water and uncovered vessel, heat transfer water also can pass to thermostatted water by uncovered vessel with heat more indirectly, and this secondary heat transfer form can make the water temperature stability in the uncovered vessel, is convenient to temperature and accurately controls.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Among the figure: 1, timer; 2, temperature controller; 3, display screen; 4, switch board; 5, temp probe; 6, thermostatted water; 7, uncovered vessel; 8, water bath; 9, heat transfer water; 10, Table vessel holder.
The specific embodiment
Below in conjunction with drawings and Examples the utility model seat is further described in detail.
As shown in Figure 1, a kind of water-bath device that is used for the serum deactivation comprises that one fills the water bath 8 of heat transfer water 9 and the switch board 4 in the casing outside, and the water bath bottom is provided with heating element heater 10, and sidepiece is provided with temp probe 5; Heating element heater 10 can form with the resistance wire coiling, and is arranged in the closed chamber that constitutes at the bottom of a Table vessel holder 11 and the water bath, and this structure can make heating element heater 10 directly not contact with heat transfer water, prevents that fouling from prolonging the service life of heating element heater.Table vessel holder 11 can be made with heat conduction good copper or stainless steel material.Place uncovered vessel 7 that fill thermostatted water 6 on the Table vessel holder.Heating element heater 10 is established temperature controller 2 (20-100 ℃ of temperature setting range can be set two temperature at least) by the main switch of water-proof cable connection switch board in the switch board, the temp probe signal connects temperature controller 2; The switch board main switch is controlled heating element heater 10 power on/off according to the temperature signal of temp probe by the temperature controller action.Also establish in the switch board timer 1 (timing range be 10 minutes to a few hours, corresponding temperature controller 2 design temperature points can be set two timings at least), timer 1 connects temperature controller 2, by the time set to this timer, the timing outage that heating element heater 10 is carried out under the established temperature is moved.Also establish display screen 3 on the switch board, intuitively display setting temperature, actual temperature and timing.
The water-bath device of present embodiment contains an amount of heat transfer water 9 earlier before use in water bath 8, place uncovered vessel 7 that fill thermostatted water 6 on the Table vessel holder; Make the water level of a little higher than thermostatted water 6 of heat transfer water 9 water levels, will cover above the water bath 8 then, only stay the uncovered of a venthole and vessel.Heating element heater 10 energising back heatings, by Table vessel holder 11 heat is delivered to heat transfer water 9 and uncovered vessel 7, heat transfer water 9 passes to thermostatted water 6 by uncovered vessel 7 with heat more indirectly, and this secondary heat transfer form can make thermostatted water 6 water temperature stabilities in the uncovered vessel 7, is convenient to temperature and accurately controls.
Below be a concrete experimental condition of serum deactivation: bath temperature is risen to 37 ℃ of insulations 4 hours, transfer test condition again: be warming up to 56 ℃ of insulations and naturally cool to room temperature after 0.5 hour from room temperature.The utility model can be 37 ℃ by temperature controller 2 first design temperatures, and sets 4 hours (comprising the heating-up time) of constant temperature time by timer 1; After 4 hours, artificial transfer test condition: by temperature controller 2 design temperatures is 56 ℃, and by 0.5 hour (comprising the heating-up time) of timer 1 setting constant temperature time.Also can set above-mentioned two temperature and two timings respectively, finish the conversion of experimental condition automatically by temperature controller 2 and timer 1.
