Description
Technical field
The utility model belongs to Chemical Engineering Laboratory equipment, particularly relates to a kind of sampler of quantitative liquid getting.
Background technology
Volatile liquid is the conventional liquid of chemical experiment, current liquid mode of getting measures with graduated cylinder and pipette after opening bottle cap, get in liquid process in this way, a large amount of escaping gases overflows from reagent bottle, because it has excitant, great injury is caused to the eyes of the person that adopts liquid, nose and throat; And getting in liquid process, get liquid too much, if the liquid got refunds the pollution that reagent bottle can cause reagent more, thus can only slattern as waste liquid, so not only waste reagent, more seriously pollute environment.
China Patent No. CN200620141672.5 discloses a kind of quantitative liquid taking device, although required liquid can be got under full closeding state, can prevent the gasification of volatile liquid from overflowing, but the extrusion of liquid also needs to adopt Compressed Gas, auxiliary device cost is higher, and is not suitable for routine experimentation use.
Utility model content
The utility model provides a kind of sampler of quantitative liquid getting, under sealing condition, can complete very simply and gets liquid and fluid to reagent quantitative, prevent the volatilization of reagent, thus cause the injury to reagent user, ensure that the cleaning of workplace.
In order to solve the problem, the technical solution adopted in the utility model is such: a kind of sampler of quantitative liquid getting, comprise liquid storage cylinder, be arranged at the piston in liquid storage cylinder, be connected with piston and the rubber stopper that matches with reagent bottle bottleneck interior shape of the pull bar that piston can be driven up and down relative to liquid storage cylinder inwall and profile, feed tube is provided with bottom liquid storage cylinder, the lower end of feed tube is connected with feed liquor conduit through rubber stopper, the port of feed tube upper end is provided with sheet check valve, described sampler also comprises the graded tube vertically arranged, the mouth of pipe of graded tube is provided with sealing-plug, the lower sidewall of liquid storage cylinder is provided with drain pipe, eluate conduit stretches in graded tube through sealing-plug, the liquid outlet of drain pipe and graded tube bottom is equipped with a cock.
In order to more accurate quantification takes out reagent, preferably, described graded tube is made up of transparent material, and graded tube tube wall is provided with measurement scale line, and minimum scale is 0.01ml.
In order to take out amount of reagent according to a preliminary estimate, described liquid storage cylinder is made up of transparent material, and liquid storage cylinder inner tubal wall is provided with measurement scale line, and minimum scale is 0.1ml.
In order to avoid the friction of feed liquor conduit and reagent bottle causes mutual infringement, feed liquor conduit is rubber tube.
In order to make sampler more stable, sampler also comprises bracing frame, bracing frame is provided be used for fixing respectively liquid storage cylinder and graded tube iron clamp.
Beneficial effect:
When needing to get liquid, close the cock on drain pipe, pull pull bar, drive piston upwards, now liquid storage cylinder inner volume increases, air pressure reduces, the sheet one-way valve opens of the port setting of feed tube upper end, reagent in reagent bottle enters in liquid storage cylinder by feed liquor conduit, reach after reagent demand reaches according to a preliminary estimate by liquid storage cylinder high scale, open the cock on drain pipe, promote piston, now sheet closed check valve, reagent flows in graded tube by drain pipe, after accurately judging that reagent demand reaches by liquid storage cylinder high scale, close the cock on drain pipe, open the cock of graded tube liquid outlet, quantitative taking-up reagent.
The utility model very dexterously solvent bottle is formed one and unidirectionally gets liquid container and quantitative liquid-discharging device, can under sealing condition, complete very simply and liquid and quantitative liquid-discharging are got to reagent, escaping gas can not be allowed to run out of the injury caused reagent user, ensure that the cleaning of workplace, in addition, the utility model apparatus structure is simple, cost is low, all applicable to existing reagent bottle.
