Abstract

The utility model discloses and a kind of there is the reagent container quantitatively measuring function, it is provided with the open plunger shaft in a upper end in bottle, and the upper end of bottle is provided with capping, is provided with piston in described plunger shaft, piston is put and is connected with piston rod, described piston rod is connected with handle through after capping; Described plunger shaft lower sides is connected with a catheter, and the other end of catheter is connected with bottom the graduated cylinder of column casing shape, and described graduated cylinder upper end is open; Described capping is provided with the sealing shroud be nested with outside piston rod, and capping side is provided with the deck for fixing sealing graduated cylinder upper end.Its reasonable in design, convenient to operation, because it adopts piston to regulate the amount of reagent in graduated cylinder, the dosage range once measured is large, various experiment demand can be met, because reagent is in the downside of piston and capping all the time, avoid reagent volatilization when measuring reagent and reveal, be particularly suited for storing volatile toxic reagent.

Description

There is the reagent container quantitatively measuring function
Technical field
The utility model relates to a kind of chemical laboratory instrument, particularly relates to a kind ofly to have the reagent container quantitatively measuring function.
Background technology
Current reagent bottle adopts wide-mouth port grinding bottle usually, although its structure is simple, but in use have the following disadvantages: (1) its usually carry suction pipe, but suction pipe does not generally quantitatively measure function, also need to be transferred in graduated cylinder to measure, operation comparatively bothers, and reduces conventional efficient; (2) when measuring reagent, its upper end oral area is in open state, and reagent easily volatilizees and pollutes, and when especially depositing tool virose volatile reagent, potential safety hazard is particularly outstanding; (3) its suction pipe produces negative pressure by the sacculus of upper end and draws reagent, and because balloon volume should not be too large, therefore its amount of reagent drawn is less, when reagent addition is larger, repeatedly need operate, reduce further operating efficiency, the potential safety hazard expand reagent volatilization, revealing.
The utility model of publication number CN 203047820 U discloses the continuous liquid sucking-discharging body device of a kind of piston, it is characterized in that establishing feed tube in the middle of in bottle cap, piston cylinder is established in outer top, piston rod one end is inserted in piston cylinder after connecting piston, liquid feed valve is established in the upper end of feed tube, liquid valve is established in the side, lower end of piston cylinder, and is connected with drain pipe.Have continuous suction, simple to operate, easy to use, time saving and energy saving, not made allowance, accurate measurement, improves the advantage of inspection speed and quality.But its structure is comparatively complicated, and cost is higher, is not suitable for popularity and uses.In addition, owing to being provided with the liquid valve, the liquid feed valve that use as check valve in its pipeline, make piping node of the present utility model more on the one hand, sealing is difficult to ensure, service life is shorter, and the quality of liquid valve and liquid feed valve differs in addition, as sealing is not good, its metering effect can be affected, further increase enforcement difficulty of the present utility model.
Utility model content
For overcoming above-mentioned technical problem, the utility model provides a kind of reasonable in design, convenient to operation, has volume and measures function, and what when can avoid measuring reagent, reagent volatilization was revealed has the reagent container quantitatively measuring function.
For realizing above-mentioned technical purpose, the utility model adopts following scheme: a kind of have the reagent container quantitatively measuring function, comprise a bottle, it is characterized in that: in described bottle, be provided with the plunger shaft that a upper end is open, the upper end of bottle is provided with capping, be provided with piston in described plunger shaft, piston put and is connected with piston rod, described piston rod is connected with handle through after capping; Described plunger shaft lower sides is connected with a catheter, and the other end of catheter is connected with bottom the graduated cylinder of column casing shape, and described graduated cylinder upper end is open; Described capping is provided with the sealing shroud be nested with outside piston rod, and capping side is provided with the deck for fixing and seal graduated cylinder upper end.
The utility model has following beneficial effect: in advance by reagent storage in the plunger shaft of bottle, when measuring reagent, pressing down handle makes piston move down, reagent enters in graduated cylinder by catheter, regulating piston position, make the reagent in graduated cylinder meet the requirements of dosage, then from its upper end reagent is poured out.Its structure is simple, with low cost, convenient to operation, implements easily, is easy to promote; Because it adopts piston to regulate the amount of reagent in graduated cylinder, the dosage range once measured is large, can meet various experiment demand, because reagent is in the downside of piston and capping all the time, avoid reagent volatilization when measuring reagent to reveal, be particularly suited for storing volatile toxic reagent.

Detailed description of the invention
Shown in Fig. 1, a kind of disclosed in the utility model have the reagent container quantitatively measuring function, it comprises a bottle 1, it is characterized in that: in described bottle 1, be provided with the plunger shaft 2 that a upper end is open, the upper end of bottle 1 is provided with capping 4, be provided with piston 3 in described plunger shaft 2, piston 3 put and is connected with piston rod 6, described piston rod 6 is connected with handle 7 through after capping 4; Described plunger shaft 2 lower sides is connected with a catheter 10, and the other end of catheter 10 is connected with bottom the graduated cylinder 9 of column casing shape, and described graduated cylinder 9 upper end is open; Described capping 4 is provided with the sealing shroud 5 be nested with outside piston rod 6, and capping 4 side is provided with the deck 8 for fixing and seal graduated cylinder 9 upper end.
During use, in advance by reagent storage in the plunger shaft 2 of bottle 1, when measuring reagent, pressing down handle 7 makes piston 3 move down, and reagent enters in graduated cylinder 9 by catheter 10, regulating piston 3 position, make the reagent in graduated cylinder 9 meet the requirements of dosage, then from its upper end reagent is poured out.Its structure is simple, with low cost, convenient to operation, implements easily, is easy to promote; Because it adopts piston 3 to regulate the amount of reagent in graduated cylinder 9, the dosage range once measured is large, can meet various experiment demand, because reagent is in the downside of piston 3 and capping 4 all the time, avoid reagent volatilization when measuring reagent to reveal, be particularly suited for storing volatile toxic reagent.
