Embodiment 1: measuring of single solvent
12, upper strata conical lower portion capacity groove can hold organic reagent different in 12 (can according to laboratory need different selections) such as: capacity groove is respectively provided with methanol from left to right, ethanol, ethyl acetate, n-butyl alcohol, acetone, chloroform, acetonitrile, petroleum ether, dichloromethane, isopropanol, espeleton, pure water.
As a example by measuring 4 300ml ethanol, the conical flask 26 of four standards is positioned on the alligator clamp 8 of conveyer belt 9 fixing, press and key 2 is set, thousands digit is selected to be 0 with up-down adjustment key 4, determine that key 3 determines, hundreds is selected to be 3 with up-down adjustment key 4 again, acknowledgement key 3 determines, up-down adjustment key 4 selects tens to be 0, acknowledgement key true 3 is recognized, regulation units is 0, acknowledgement key 3 confirms, display screen 1 automatic jumps to conveyer belt advance number of times interface, arranging advance number of times with up-down adjustment key 4 regulation is 4 times, after acknowledgement key 3 confirms, open the big air cock of rotary 24 in upper end capacity groove lid 25, press initiating key 5, valve switch 28 automatically opens up, flow out baffle plate 14 on the left of the mouth of pipe vertically deployable, measure beginning.Principle: operating process all controls by having programmed the circuit board 21 of program, after pressing initiating key 5, valve 28 is opened, circuit board record is by flowing out the volume flow of the mouth of pipe, contained by first conical flask and take flowed out organic solvent volume, after recorded 300ml, valve switch 28 is closed, conveyer belt 9 advances forward a certain distance, (distance is that second conical flask moves to flowing out below the mouth of pipe), valve automatically opens up, until record flows out 300ml, second conical flask sends out, come in for 3rd, by that analogy until four conical flask subpackages are complete, valve is not then turned on.
Note: the effect of scalable vertical baffle 14 be when can lid conical flask 26 through when resistance can be relied on bottle cap to be covered can be in lid conical flask 26, it is to avoid organic solvent volatilizees.
Instrument internal is when having leakage or gas leakage situation, and volatilization gas content detection alarm device can automatic alarm.
Embodiment 2: mixing match solvent weighs
Upper strata solvent distribution is identical with embodiment 1, the ratio of proportioning solvent computed in advance and volume, such as: measure 100ml chloroform respectively: methanol=1:9,1:4,1:1,2:3 i.e. volume ratio is: 10:90,20:80,50:50,40:60.Four conical flasks 26 are placed on alligator clamp 8 fixing, selecting the adjusting key below display 10 to carry out operation with solvent makes its display reminding chloroform measure, key 2 is set and determines that key 3 is respectively provided with and determines chloroform volume 10/20/50/40ml, and arrange mixing channel 29 to move number of times be 4 times, press initiating key 5；The chloroform correspondence chloroform mouth of pipe 30 valve in ten two-port valves 27 is opened and flows out the equal-volume chloroform of setting successively, in like manner, carrying out operation makes display display reminding methanol measure, and is respectively provided with and determines the volume 90/80/50/60ml of methanol, and arranges mixing channel 29 and move number of times 4 times.Equal-volume methanol (the note: often flow out chloroform and the methanol of one group of Concentraton gradient of setting is opened and flowed out successively to the methanol correspondence mouth of pipe 31 valve in ten two-port valves 27, the chloroform mouth of pipe 30 of ten two-port valves 27 and the valve switch of the methanol mouth of pipe 31 mouth of pipe all can be closed, until the solvent inside mixing channel flows to the conical flask of correspondence, mixing channel moves to next conical flask upper end, the chloroform mouth of pipe 30 and the methanol mouth of pipe 31 mouth of pipe valve switch are again turned on, the chloroform of another group Concentraton gradient of mixing match and methanol).When a Concentraton gradient circulate from mixing channel complete after, circuit board 21 can be delivered a signal to, circuit board can send movable signal, make mixing channel mobile fixing segment distance on steel column and its track, arrive next conical flask upper end and carry out the proportioning of next Concentraton gradient, by that analogy until four Concentraton gradient proportional quantities take complete.
Embodiment 3: multiple proportioning solvents weigh
The ratio of proportioning solvent computed in advance and volume, such as: measure 100ml w:x:y:z=1:2:3:4 respectively, 1:4:5:10,2:3:6:9, i.e. volume ratio are: 10:20:30:40,5:20:25:50,10:15:30:45.Three conical flasks 26 are placed on alligator clamp fixing, selecting the adjusting key 4 under display 10 to carry out operation with solvent makes it be shown as w, key 2 is set and determines that key 3 is respectively provided with and determines w volume 10/5/10ml, and mixing channel is set moves number of times 3 times, press initiating key 5, the mouth of pipe valve that w solvent in ten two-port valves 27 is corresponding is opened and flows out the equal-volume w of setting successively, in like manner, carrying out operation makes display 10 be shown as w, it is respectively provided with and determines the volume 20/20/15ml of w, and mixing channel is set moves number of times 3 times.The mouth of pipe valve that w solvent in ten two-port valves is corresponding is opened and flows out the equal-volume w of setting successively, the method to set up of y and z and w, identical (the note: often flow out the w:x:y:z of one group of Concentraton gradient of x, its each self-corresponding valve switch of ten two-port valves all can be closed, until the solvent inside mixing channel flows to the conical flask of correspondence, and moving to next conical flask upper end, mouth of pipe valve switch is again turned on, the mixed solvent of another group Concentraton gradient of proportioning.) when a Concentraton gradient circulate from mixing channel complete after, circuit board can be delivered a signal to, circuit board can send movable signal, make mixing channel mobile fixing segment distance on steel column and its track, arrive next conical flask upper end and carry out the proportioning of next Concentraton gradient, by that analogy until three Concentraton gradient proportional quantities take complete.
Embodiment 4: the cleaning of mixing channel
Pressing resetkey 13 makes mixing channel 29 return to one end, left side, a washer bottle is put at exit lower end, press cancel key 12, pure water in capacity groove flows out from ten two-port valves 27 automatically, mixing channel is rinsed 3 minutes, then being automatically drained out cleanout fluid in washer bottle, heating mantle 19 heats automatically closes after quickening volatilizes 4 minutes, and exhaust fan 20 is automatically switched off after carrying out gas air draft 6 minutes simultaneously.Whole process is controlled by lower circuit plate 21, and cleaning process display lamp 11 can show cleaning progress.
Note: the error that 1. experiment material is brought is inevitable, such as: internal residual etc., this instrument selection conical lower portion capacity groove is contemplated to reduce the error that error internal residual brings.2. the material of corrosion resistance selected by flexible pipe.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive equivalent or change in addition according to the technical solution of the utility model and utility model thereof, all should contain within protection domain of the present utility model.
