Description
The utility model relates to a kind of groove, and it is specially adapted to measure surface tension of liquid or gas-liquid interface unimolecular layer surface mould.
The surface tension and the variation of measuring liquid are one of important method of ambit research material interface activity such as physical chemistry, colloidal chemistry, biology, the experimental provision that is used to measure the surface tension of solution or is in gas-liquid interface amphiprotic substance unimolecular layer mould comprises contains groove and the tonometry sensor two parts that carry solution (title parfacies), measure adopt of effect of material in gas-liquid interfacial monolayer and it and the parfacies more for a long time and decide the area groove, the volume of carry containing of this groove does not wait to 100 milliliters from tens of, is flat square or circular.The shortcoming of this groove is: 1, the dynamics that mixes with solution of sample is relatively poor.Change for measuring reflection test substance and the unimolecular layer surperficial mould that causes that interacts in real time, adding material in the parfacies (common sample volume be parfacies liquor capacity 1/100～1/1000) need be uniformly dispersed in whole parfacies solution in the short time as far as possible.Reach this purpose preferably means be to stir with the direct stirring of connecting rod driven vane or the isolation of magnetically-actuated.Because it is long or cross conference and cause liquid fluctuating isolate to stir used stirrer, the stability of serious interferometry, so the length of used magnetic stir bar much smaller than the line footpath of groove bottom, this usually leaves over again and stirs dead angle (promptly closing on pond downside wall part).2, groove to sprawl efficient not high.Groove sprawl the surface area that parfacies solution that efficient is meant unit volume is sprawled at Chi Zhongke.Both made and adopted pancake pond body, the parfacies volume is still bigger, and it is more to this means that sample size to be measured in solution and the solution needs, the waste fund.Be the saving fund, will reduce the parfacies volume of groove usually as far as possible, thereby reduce sample, particularly precious amount of samples.The parfacies volume that reduces groove generally has two kinds of approach: the one, reduce the radial dimension of groove, i.e. and its cross-sectional area area of unimolecular layer film formation surface just, but too small surface area is unfavorable to the formation and the capillary measurement of unimolecular layer; The 2nd, reduce the degree of depth of groove, but reduce groove depth can make stir cause to capillary interference aggravation; If do not stir, add to the sample mixing and be diffused into solution-unimolecular layer interface at short notice in the groove, just can not truly reflect the dynamic change of this material and membrane interaction.In sum, under the situation that does not influence stalagmometry, improve the hybrid dynamics characteristic of groove; Reducing amount of samples is to decide unsolved always problem in the experiment of area unimolecular layer.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of surface tension measuring tank that can measure while stirring is provided, and its parfacies volume is little, and kinetic measurement responds.
The utility model surface tension measuring tank, comprise cell body and be arranged on the interior groove pond of cell body, described groove pond comprises that being followed successively by circular stirring pool, back taper stirring Buffer Pool and circular surface from the bottom to top amasss the qualification groove, surface area limits groove end face outward flange and is provided with circular anti-overflow groove, there is not well on the described cell body, the one end opening is in the stirring pool sidewall, and the other end is opened on cell body outer wall top, contiguous anti-overflow groove.
The utility model surface tension measuring tank, the aperture of wherein said well are 0.5mm.
The circular diameter specific surface area limits the big 10～15mm of groove diameter in the utility model surface tension measuring tank, wherein said anti-overflow groove.
The circular diameter specific surface area limits the big 12mm of groove diameter in the utility model surface tension measuring tank, wherein said anti-overflow groove.
The utility model surface tension measuring tank, the cone angle of wherein said stirring pool are 100140 °, and it is 0.3～0.5mm that surface area limits groove deep, and the anti-overflow groove deep is 0.5～1.5mm.
The utility model surface tension measuring tank, the cone angle of wherein said stirring pool are 120 °, and it is 0.4mm that surface area limits groove (4) groove depth, and anti-overflow groove (3) groove depth is 1.2mm.
The advantage and the good effect of the utility model surface tension measuring tank are: because it adopts back taper to stir the Buffer Pool pond, overcome the disadvantage of leaving over the dead angle, and make the parfacies liquor capacity reduce, thus reduced the especially precious amount of samples of sample, economize on the use of funds.Again because the cross-sectional area of surface area qualification groove is the long-pending sectional area much larger than stirring pool of unimolecular layer film formation surface, be arranged in stirring pool because the flow velocity of the eddy current that the stirrer rotation produces weakens gradually at from the bottom to top transmittance process with regard to making, thereby reduced interference, improved measuring stability and accuracy surperficial unimolecular layer.
Other details of the utility model surface tension measuring tank and characteristics can just can be cheer and bright by reading the embodiment hereinafter encyclopaedize in conjunction with the accompanying drawings.
Fig. 1 is the vertical view of the utility model surface tension measuring tank;
Fig. 2 is the A-A face cut-open view of Fig. 1.
Surface tension measuring tank as depicted in figs. 1 and 2, it comprises cell body 1 and is arranged on groove pond in the cell body 1, described groove pond comprises that being followed successively by circular stirring pool 6, back taper stirring Buffer Pool 5 and circular surface from the bottom to top amasss qualification groove 4, the degree of depth that surface area limits groove 4 is that its end face outward flange of 0.4mm is provided with circular anti-overflow groove 3, the circular diameter specific surface area limits the big 12mm of groove 4 diameters in the anti-overflow groove 3, and anti-overflow groove 3 degree of depth are 1.2mm.Described well 2 one end openings are in stirring pool 6 sidewalls, and the other end is opened on cell body 1 outer wall top, contiguous anti-overflow groove 3, and the aperture of well is 0.5mm.It is back taper that the utility model stirs Buffer Pool 5, and its cone angle is 120 °, has reduced the parfacies liquor capacity, thereby reduces amount of samples, economizes on the use of funds.The effect of anti-overflow groove 3 has two: prevent on the one hand in the groove liquid cell body rock or moving process in overflow, under the operating position water is not injected into anti-overflow groove 3 water levels at groove on the other hand, reduce the contaminated of groove.Because magnetic stir bar does not have the fixing support center of circle when rotated, meeting translation in the time of rotation is provided with stirring pool 6 and can prevents that stirrer from moving along stirring on Buffer Pool 5 sidewalls, influences stalagmometry stability in the bottom of hybrid chamber in addition.
Experimental result shows, slowly run down at stirrer, sample and the mixed characteristic of parfacies solution in the pond obviously are better than having the groove of the common cylindrical shaped shape of the same degree of depth of same surface area, and the volume of used parfacies liquid only is original half, stirrer is located also better in rotary course.The surface tension measuring tank of this kind structure is easy to clean in addition.
