Description
Technical field
The utility model belongs to experimental instrument and equipment field, particularly a kind of thermos bottle type reagent bottle.
Background technology
Titration operation is medical science, pharmacy student must the skilled experimental skill of grasping.Preparatory work of experiment personnel can be divided in titrating solution in the reagent bottle of 1L left and right in advance.When titration operation, for avoiding the solubility fluctuation of titrating solution large and reduce the waste of titrating solution, need the hand-held reagent bottle of student directly from the top of buret toward buret in filling solution, because the bore at buret top is less, often make solution pour out outside buret, cause the waste of titrating solution.The innovation and creation that on June 6th, 2012, application number was 201120267526.8 disclose a kind of reagent bottle; it makes sharp mouth shape circular bottleneck; the time of falling liquid; point mouth is aimed at the buret mouth of pipe; solution forms thin current; make the time of falling liquid be difficult for solution to be poured on buret outer wall, Protection personnel avoid chemical damage.But for schoolgirl, the reagent bottle of holding in both hands 1L left and right directly falls, and has certain difficulty, reagent bottle is often understood landing and is broken.
On the other hand, because the concentration between titrating solution levels is variant, the result fluctuation of titration is sometimes larger.Particularly, in the time doing titration experiments winter, add the reason that solubility reduces, even if student operates better, the fluctuation of its experimental result is still larger, and student's enthusiasm is had to considerable influence.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of thermos bottle type reagent bottle is provided, and this reagent bottle can not only be annotated titrating solution to buret easily, and can reduce the concentration difference between levels titrating solution in reagent bottle.
The scheme that the utility model solve the technical problem is: a kind of thermos bottle type reagent bottle, comprises the plastic casing of column and be positioned at the glass inner bag of plastic casing; On the sidewall of plastic casing, be provided with observation panel and lever, observation panel is vertical strip, and the top of plastic casing is provided with leg, and a diversion division is arranged at the top of plastic casing; The top of glass inner bag is gateway, and there is an obturator gateway, and the middle part of glass inner bag has a narrow to make glass inner bag be 8-shaped.
When Preparatory work of experiment personnel pack titrating solution into reagent bottle, fill 3/4 of reagent bottle total capacity, can see the liquid level of titrating solution by observation panel.Student, before experiment starts, is inverted reagent bottle, allows the leg on plastic casing top stand on laboratory table, realizes the object of even titrating solution total concentration by the location swap between levels titrating solution.The speed when narrow of glass inner bag can strengthen upper strata titrating solution and falls, plays the effect that stirs titrating solution.Reagent bottle is inverted several times repeatedly, and the Blending Efficiency of Blending of titrating solution is better.
As further technical scheme, described obturator comprises the bottle stopper of ground processing, and the top of bottle stopper is knob, and the top of knob and plastic casing is threaded connection, on bottle stopper, have rubber washer, the rotation of knob has the bottle stopper of rubber washer to be pressed on the gateway of glass inner bag in cover.
This obturator can prevent that reagent bottle from leakage occurring while inversion.
As technical scheme further, on described knob, offer 1 through hole and 2 catch, 2 catch are symmetrical arranged about through hole, and the top of bottle stopper is fixed with a bar portion, and bar portion is through through hole.
2 catch on knob facilitate exerting oneself of thumb and forefinger, can easily knob be tightened in to the gateway of glass inner bag.In the time that knob is screwed out to gateway, hand-held pole portion can extract bottle stopper.
As technical scheme further, between described plastic casing and glass inner bag, be provided with heater, heater is positioned at narrow place.
When cold day does laboratory, be to increase the solubility of titrating solution, can heater, the actual concentrations of titrating solution and theoretical concentration are consistent as far as possible, ensure that experiment carries out smoothly and obtain the experimental data of expecting.
In sum, the utlity model has advantage simple in structure, successful, can not only titrating solution be annotated to buret convenient and strength-savingly, and in reagent bottle, the concentration between levels titrating solution is even, provide smoothly guarantee for titration experiments.
