Abstract
The utility model discloses a tee joint potassium chloride salt bridge and belongs to the technical field of instruments of analytical chemistry and electrochemistry. The tee joint potassium chloride salt bridge is formed by a rubber cap, an upper vertical pipe, lower side pipes, and salt bridges. The upper vertical pipe is in bilateral symmetry, and the two ends of the upper vertical pipe are respectively connected to the lower side pipes. The bottom ends of the lower side pipes are respectively and fixedly connected with the salt bridges. The rubber cap is installed at the upper end of the upper vertical pipe. The tee joint potassium chloride salt bridge can be permanently used as long as a certain liquid level of the potassium chloride solution is kept. When porous ceramics are used for the salt bridges, one drop can seep from the potassium chloride solution every four hours, liquid junction potential can be reduced and stabilized, agar is not used so preparation is easy, and there is no risk of metamorphism or falling. Due to the salt bridge tee joint frame structure, it is easy to add or replace the potassium chloride solution. In addition, tumbling doesn't occur easily because the gravity center of the tee joint potassium chloride salt bridge inclines downwards.
Description
Technical field
The utility model relates to a kind of threeway potassium chloride salt bridge, belongs to analytical chemistry galvanochemistry technique with the apparatus field.
Background technology
At present, known potassium chloride salt bridge consists of saturated potassium chloride and agar, and its object is to reduce and stable liquid junction potential.Common preparation method, for add agar and distilled water in beaker, uses water bath heating that agar is heated to dissolve completely.Then add potassium chloride fully to stir, potassium to be chlorinated adds this solution in advance in curved good glass tube with dropper or siphon after dissolving completely while hot, standingly after agar condenses, just can use.Existing potassium chloride salt bridge exists that loaded down with trivial details, the easy mouldy sex change of preparation process, port easily come off, liquid junction potential is unstable, need the deficiency of the original agar of Ex-all while changing.
Utility model content
In order to overcome above-mentioned technical deficiency, the utility model provides a kind of threeway potassium chloride salt bridge, this threeway potassium chloride salt bridge effectively solved that loaded down with trivial details, the easy mouldy sex change of existing potassium chloride salt bridge preparation process, port easily come off, liquid junction potential is unstable, need the deficiency of the original agar of Ex-all while changing, and only uses Klorvess Liquid to reach to reduce and the effect of stable liquid junction potential.
The utility model solves the technical scheme that its technical matters adopts: threeway potassium chloride salt bridge is comprised of Capsule, upper riser, lower side pipe, salt bridge, the lower side pipe of the symmetrical connection respectively of upper riser, the bottom of lower side pipe is fixedly connected with respectively salt bridge, and the upper end of upper riser is equipped with Capsule.
The beneficial effects of the utility model are: this threeway potassium chloride salt bridge is as long as keep the certain liquid height of Klorvess Liquid forever to use.Porous ceramics can make Klorvess Liquid within 4 hours, ooze out 1 as salt bridge, can reduce and stable liquid junction potential, and owing to not using agar, so be easy to preparation, not have risk rotten, that come off.In addition, owing to using salt bridge threeway shelf structure, so be easy to add, change Klorvess Liquid.In addition, due to the center of gravity of threeway potassium chloride salt bridge of the present utility model on the lower side, so be difficult for toppling.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is a kind of threeway potassium chloride of the utility model salt bridge contour structures schematic diagram.
Fig. 2 is a kind of threeway potassium chloride of the utility model salt bridge sectional structure chart.
Fig. 3 is a kind of threeway potassium chloride of the utility model salt bridge plan structure figure.
In figure 1, Capsule, 2, upper riser, 3, lower side pipe, 4, salt bridge.
Embodiment
As shown in Figure 1, threeway potassium chloride salt bridge is comprised of Capsule 1, upper riser 2, lower side pipe 3, salt bridge 4, the lower side pipe 3 of the symmetrical connection respectively of upper riser 2, and the bottom of lower side pipe 3 is fixedly connected with respectively salt bridge 4, and the upper end of upper riser 2 is equipped with Capsule 1.
Described upper riser 2 and lower side pipe 3 are fired and are made for the glass tube being communicated with, and its overall diameter is 6mm, and interior diameter is 4mm; Described salt bridge is made by porous ceramics, and its diameter is all 4mm mutually with the interior diameter of lower side pipe 3, and its connected mode is served as reasons the glass tube inclusion hot melt of lower side pipe 3 in lower side pipe 3 bottoms.
During use, Klorvess Liquid is poured into by the port of upper riser 2, made the liquid level of twice side pipes 3 be connected and can use, the concentration of Klorvess Liquid can suitablely as required be determined.
Claims (1)
