Abstract
The utility model relates to a buffering liquid formula diagram card which comprises a circular positioning disk, a circular rotary plate and a circle center fixing element, wherein, the circular positioning disk and the circular rotary plate are fixedly overlapped by the circle center fixing element while the circle centers of the circular positioning disk and the circular rotary plate are used as shafts; a window is arranged at the positioning disk in a stooping mode; pH values, buffering liquid formula and volume values of the X liquid of the formula are respectively arranged at the surface of the positioning disk according to the concentric circle mode; a rotation handle is arranged at the circle edge of the rotary plate, the volume values of the Y liquid of the formula are arranged at the surface of the rotary plate according to the concentric circle mode, and the formula of the generally-used buffering liquid is concentrated on a circular clamping disk. The utility model has the advantages of quick lookup, convenient carryover, convenient use, simple structure, low cost and wide application range.
Description
The utility model relates to a kind of buffer formulation chart card.
Damping fluid is the solution that a class is made up of certain material, and when adding a certain amount of acid or alkali, its pH (being the pH value) changes very little or almost constant.Because damping fluid has the characteristic of stablizing the pH value, it is widely used in experiments such as biology, chemistry and medical science.People have found out the prescription of multiple damping fluid in practice, the needs that can adapt to different pH values, and will use the buffer formulation appendix always in different experiment postscripts, therefore, often must ransack, consult prescription earlier at the preparation damping fluid, by formulated, so often lose time again, also delay experiment sometimes.
The purpose of this utility model aims to provide a kind of buffer formulation of will using always and concentrates on the chuck, searches disc type buffer formulation card quick, easy to use.
The utility model comprises circular price fixing, round turntable and center of circle fixture, and price fixing and rotating disk are overlapping fixing with two dish circle core shafts by center of circle fixture, and price fixing is positioned at the rotating disk top; Price fixing is arranged the volume numerical value of X solution in pH value, buffer formulation and the prescription respectively along the radial display window of offering by the concentric circles mode on the card; The rotating disk card has been arranged Y liquor capacity numerical value in the prescription by the concentric circles mode, and in turret loop edge bidding note, said mark can be established projection or handle at the turret loop edge.
Rotate rotating disk during use, allow required pH value position on the indicia point price fixing of turret loop edge, according to the buffer formulation that will prepare, can allot various required damping fluids fast according to Y liquor capacity numerical value on the rotating disk that shows in the X liquor capacity numerical value of pH value position correspondence on the price fixing in the prescription-filling card and the price fixing display window, the prescription that the utility model will be used damping fluid always concentrates on the circular chuck, can save in the routine experimentation work and often need ransack, consult the trouble of required buffer formulation, have and be easy to carry, advantage such as easy to use: and selected 12 kinds of damping fluids are contained biology substantially, biochemical, chemical examination waits damping fluid commonly used in the experiment, applicable to above students of subject college such as biology and medical science, research work personnel, hospital and the lab technician's of factory etc. needs, thereby have bigger applicable surface.And this prescription-filling card is simple in structure, with low cost.
Fig. 1 is the utility model price fixing synoptic diagram.
Fig. 2 is the utility model rotating disk synoptic diagram.
The utility model is described in further detail below in conjunction with accompanying drawing.
See Fig. 1,2, circular price fixing 1, round turntable 2 serves as that axle is overlapping fixing by center of circle fixture 3 with the two dish centers of circle, and price fixing 1 is positioned at rotating disk 2 tops, and price fixing 1 is identical with the radius of rotating disk 2.Price fixing 1 is along the radial display window 11 of offering, on the card by the concentric circles mode respectively clockwise direction arrange pH numerical value, buffer formulation promptly fill a prescription in the volume numerical value of X solution.Rotating disk 2 ring edge are established and are rotated handle 21, and card is pressed the corresponding respectively volume numerical value of counterclockwise arranging Y solution in the prescription of concentric circles mode.For example, desire to join pH and be 3.4 glycocoll and hydrochloride buffer, at first determine institute and join buffer formulation the 2nd row, rotating handle 21, to allow its set arrow logo aim at the pH value shown in price fixing 1 be 3.4 position, and look for to the 2nd row go up with pH value be that the volume that 3.4 corresponding X solution are HCL solution is 6.4mL, and the numerical value 50mL that display window 11 rotating disk 2 concentric circless the 2nd shown in interior are arranged is the volume of Y solution (glycocoll).The operation instruction or the guide of prescription-filling card can be set at the price fixing core.
Except that special mark, the concentration of X solution and Y solution is 0.2mol/L on the prescription-filling card.
Claims (5)
