Abstract
The utility model belongs to the field of experiment instruments, and in particular relates to a volumetric solution filling device for student experiments. The filling device comprises a solution bottle (1), wherein the solution bottle (1) is provided with a bottle cover (2). The filling device is characterized by comprising a drainage tube (3), wherein one end of the drainage tube (3) is positioned inside the solution bottle (1); a flow regulator (4) is arranged at the other end of the drainage tube (3); a branch tube (5) is arranged at the flow regulator (4) of the drainage tube (3); the branch tube (5) is connected with a syringe (6). By adopting the filling device, the purpose of introducing a volumetric solution in the solution bottle into a burette can be achieved with the combination of ordinary articles, the manufacturing is simple, the effect is remarkable, and both the waste of the volumetric solution is reduced and the solution bottle is not broken.
Description
Technical field
The utility model belongs to experimental instrument and equipment field, particularly a kind of student experimenting vs filling apparatus.
Background technology
Titration operation is chemistry, biological, pharmacy student must the skilled experimental skill of grasping.Before student enters laboratory, Preparatory work of experiment personnel can be divided in vs in the solution bottle of 1L left and right in advance.Before titration experiments, first student will pour vs in acid or base buret into.For keeping solution concentration constant, the direct hand-held solution bottle of General Requirements student 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 vs.
The innovation and creation that on January 16th, 2013, application number was 201220218842.0 disclose a kind of wide mouthful of buret, this buret is provided with the container that oral area is larger at top, to facilitate, vs is poured into from solution bottle to buret inside, medicine and pollution laboratory avoid waste.The weak point of this scheme is: increased technology difficulty 1, to the processing of buret; 2, buret top increases after container, during preservation, takes up space, and packing is also inconvenient with transportation; 3, the hand-held larger solution bottle of student is directly toward the interior vs of buret, and the easy landing of solution bottle is smashed.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of student experimenting vs filling apparatus is provided, and this device can be annotated the vs in solution bottle to buret convenient and strength-savingly.
The scheme that the utility model solve the technical problem is: a kind of student experimenting vs filling apparatus, comprise solution bottle, solution bottle has bottle cap, described filling apparatus comprises drainage tube, one end of drainage tube is positioned at solution bottle, the other end of drainage tube is provided with flow regulator, and drainage tube is provided with arm at flow regulator place, and arm is connected with syringe.
Flow regulator conventional flow regulator while having an intravenous drip for nurse, the pulley of flow regulator is shifted drainage tube all-pass of the top onto, and the pulley of flow regulator is shifted drainage tube full cut-off of below onto.When buret need be annotated vs, drainage tube is positioned to the top that buret is filled in one end outside solution bottle, the pulley of flow regulator is shifted onto to below, twitch syringe, see when vs in solution bottle flows through, the pulley of flow regulator is slowly up pushed away, and vs just enters buret, when buret is filled buret soon, the pulley depress of flow regulator is made to drainage tube full cut-off.
As further technical scheme, described filling apparatus comprises that one can be placed on the block at buret top, blocks a shot cylindrical, and block has a cavity, and an end of drainage tube is positioned at cavity.
This scheme can prevent that the end of drainage tube from skidding off from the top of buret when work, and on the other hand, the end of drainage tube is owing to being positioned at cavity, and while being placed on experiment tables, end can be not contaminated.
As further technical scheme, described filling apparatus has a rubber plug, and described bottle cap offers and can hold the through hole that drainage tube passes through, and the size of rubber plug and the aperture of through hole are suitable.
Some vs need to keep in Dark Place with brown solution bottle, while extracting vs, does not preferably open wide bottle cap and carries out.Adopt the advantage of this scheme to be: at ordinary times used time not, with rubber plug, to clog through hole.In the time of need to extracting the vs in solution bottle, extract rubber plug, drainage tube is filled in through hole, reduce the impact of sight on vs.
The beneficial effects of the utility model are: the article combination that this filling apparatus only need be conventional can realize the object of the vs in solution bottle being introduced to buret, makes simply, and successful, can reduce the waste of vs, can not smash solution bottle again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, solution bottle; 2, bottle cap; 3, drainage tube; 4, flow regulator; 5, arm; 6, syringe; 7, block; 8, cavity; 9, rubber plug; 10, through hole.
Embodiment
As shown in Figure 1, a kind of student experimenting vs filling apparatus, comprises solution bottle 1, and during due to student experimenting, the vs in a solution bottle 1 need repeatedly be used by several groups of students, and generally employing capacity is 1L or larger solution bottle.Solution bottle 1 has bottle cap 2 and rubber plug 9, and bottle cap 2 offers through hole 10, and the aperture of the size of rubber plug 9 and through hole 10 is suitable.
Filling apparatus comprises drainage tube 3, and the through hole 10 on bottle cap 2 can hold drainage tube 3 to be passed through.One end of drainage tube 3 is positioned at solution bottle 1, and the other end of drainage tube 3 is provided with flow regulator 4, and drainage tube 3 is provided with arm 5 at flow regulator 4 places, and arm 5 is connected with syringe 6.
Filling apparatus comprises that one can be placed on the block 7 at buret top, and block 7 is cylindrical.Block 7 has a cavity 8, and an end of drainage tube 3 is positioned at cavity 8.
