Description
Technical field
The present invention relates to a kind of water-bath prepared for nuclear magnetic resonance sample.
Background technology
At present, known water-bath is for heating detected solution sample, promoting what the solute in solution fully dissolved.Often
Accelerate solute dissolving or have to the method that sample stirs：A magnetic particle is put into the solution, and mixer puts burning
The chassis interior of cup includes coil, and passing to alternating current makes magnetic particle rotation, so as to drive liquid to do eddying motion, reaches solute and stirs
Mix uniform purpose.But some solution examples may corrode or pollute magnetic particle, cleaning, the maintenance of magnetic particle are influenceed
And follow-up use.
The content of the invention
In order to overcome the shortcomings that solute inconvenience sometimes is put into magnetic particle in existing water-bath sample dissolution, the present invention proposes one
Kind prepares the water-bath of nuclear magnetic resonance sample.The present invention, may be dirty without cleaning without toward foreign object is put into sample solution
The magnetic particle or other function sundries of dye.Compared with current shaking table class water-bath, the present invention can make the dissolved efficiency of solute more
It is high.

Individual temperature control instrument, the temperature control instrument are connected with the main switching control of relay, output main control signal to relay.
The opening or closure of the main control signal control sub-control switch, i.e. sub-control switch are same with the action of main switching control
Step acts, and main switching control is opened sub-control switch and opened, and main switching control closure then drives sub-control switch also to close.It is described
The both ends of relay sub-control switch are connected with DC power source adapter and Resistant heating band respectively.Resistant heating band, after
Electrical equipment and DC power source adapter form a series loop.
The clamping device includes the clip and motor of holding test tubes.The clip of holding test tubes is clamped in the interposition of test tube
Put, test tube is inserted vertically into the bath solution of water-bath inner bag loading built with copper sulfate solution, the bottom of the test tube.Electricity
The output end of machine is connected with clip.Motor and DC power source adapter are located in water-bath, and relay also is located in water-bath.
The temperature sensor is mounted in the bottom of water-bath inner bag, measures the temperature of bath solution in inner bag, temperature in real time
Control instrument is connected with temperature sensor.When solution temperature is less than design temperature, at such as 40 degrees Celsius, temperature control instrument output
One switching signal to relay, relay main switching control is closed so that sub-control switch is also closed, then dc source is adapted to
Device is connected with Resistant heating band, and heating tape starts to the bath solution heating in inner bag, solution heating.When temperature sensor is examined
When measuring bath solution temperature higher than 40 degrees Celsius, temperature value is reached temperature control instrument, temperature control instrument stops output
Switching signal, relay main switching control disconnect, and sub-control switch also disconnects, DC power source adapter and Resistant heating band it
Between path be disconnected, heating tape stops giving inner bag heating, bath solution continues and surrounding environment does energy exchange and at a temperature of
Drop.When temperature 40 degree Celsius of the temperature again below setting, in temperature sensor, temperature control instrument, relay, direct current
Under the interaction of source adapter and heating tape, retriggered heated water bath solution.In whole nuclear magnetic resonance sample preparation process
In, heating and temperature-fall period go round and begin again.When preparing NMR water apperance product, clip clamping is equipped with the nuclear-magnetism not being completely dissolved
Detection sample copper sulfate solution test tube be placed in the bath solution of water-bath inner bag, test tube by clamping device motor driven
Spin is done to rotate.As the nuclear-magnetism detection sample copper sulfate solution in test tube is heated to specified temp, then solution bottom
Copper sulphate precipitate also accelerate to dissolve.
Water-bath of the present invention is connected after 220V AC powers, and the motor of clamping device starts running, and is driven on water-bath
The clip of side makes clamped test tube spin motion.Bath solution is pure water.While connecting mains supply, the temperature passes
The temperature of bath solution in sensor detection water-bath, when the temperature of bath solution is less than the temperature set, such as 40 degrees Celsius,
Temperature control instrument outputs signal to relay, and relay main switching control and sub-control switch sequentially turn on, the direct current of series connection
Power supply adaptor forms loop with heating tape and started working, and heating tape starts to warm up, and is heated to bath solution in pot, and then give
Test tube kernel Magnetic testi sample heats, i.e., copper-bath heats.When fluid temperature is higher than 40 degrees Celsius in water-bath, temperature
Sensor exports actual temperature signal to temperature control instrument in real time, and the temperature control instrument exports a signal to relay again
Device, relay shut-off, heating tape disconnect with DC power source adapter, stop heating.
The present invention can avoid the foreign objects such as stirring magnetic particle from being placed in solution, be compared with shaking table class shaking bath pot, the present invention
Dissolved efficiency it is higher.
