Abstract
The utility model discloses a rapid and quantitative pipettor. The rapid and quantitative pipettor comprises a sampling tank and a liquid feeding tank, wherein a valve for communication is arranged between the sampling tank and the liquid feeding tank; the sampling tank is internally provided with a supporting frame; pipettes are arranged on the supporting frame; a liquid level control device is further arranged between the sampling tank and the liquid feeding tank. According to the rapid and quantitative pipettor, the liquid level in the sampling tank keeps stable by the liquid level control device; when the pipettes are arranged in the sampling tank, the amount of liquid in the pipettes is not changed so as to realize rapid and quantitative sampling.
Description
Technical field
The utility model relates to a kind of liquid-transfering device, is specifically related to a kind of liquid-transfering device that can quantitative liquid.
Background technology
In the routine work of laboratory, quantitatively pipetting liquid is a basic operation, generally with ear washing bulb, pipette, operate, ear washing bulb is withstood on pipette and to draw and to emit liquid, operate very inconvenient, for part industry laboratory, the laboratory of geology industry for example, the workload of every day is very heavy, and task is tighter, do so more consuming time, complex operation.Especially when colorimetric method is measured constituent content, often need to add successively multiple different solutions, operating process is more.
Utility model content
Complex operation when the technical problems to be solved in the utility model is quantitative liquid getting, provides a kind of fast quantification pipettor simple to operate.
The technical solution of the utility model realizes in the following manner: a kind of fast quantification pipettor, comprise sampling groove and add liquid bath, sampling groove and add the valve that is provided with connection between liquid bath, in sampling groove, be provided with bracing frame, on bracing frame, be placed with pipette, sampling groove and add and be also provided with fluid level control device between liquid bath.
Described fluid level control device comprises the ball float being arranged in sampling groove, and ball float is connected with valve by connection cord, and connection cord is walked around pulley.
Described pipette lower diameter is greater than upper diameter.
The described liquid bath sidewall that adds is provided with handle.
In the utility model, by fluid level control device, make the liquid level in sampling groove keep stable, when pipette is put into sampling groove, in pipette, the amount of liquid can not change yet, and then has realized fast quantification sampling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that schematic diagram is looked on a left side of Fig. 1.
Fig. 3 is the schematic top plan view of Fig. 1.
The specific embodiment
As shown in drawings, a kind of fast quantification pipettor, comprise sampling groove 2 and add liquid bath 3, sampling groove 2 and add the valve that refluxing opening 8 places between liquid bath 3 are provided with connection, in sampling groove 2, be provided with bracing frame 5, on bracing frame 5, be placed with pipette 1, sampling groove 2 and add and be also provided with fluid level control device between liquid bath 3.Described fluid level control device comprises the ball float 7 being arranged in sampling groove 2, and ball float 7 is connected with valve by connection cord, and connection cord is walked around pulley 4.
The utility model keeps the operation principle of liquid level stabilizing in sampling groove as follows: when sampling groove 2 liquid levels lower, ball float 7 balls decline thereupon; Ball float 7 pulls valve, thereby the liquid that makes to add in liquid bath flows into sampling groove; When the liquid level in sampling groove 2 reaches quantitative height, ball float 7 upwards floats, and makes valve closing.Thereby realized and allowed the object of liquid level stabilizing at certain altitude.
In the utility model, fluid level control device also can adopt other modes, such as sensor is set in sampling groove, the unlatching of empty profit sensor by-pass valve control.
When the utility model is used, pipette 1 is placed on bracing frame 5, by Action of Gravity Field, orders about liquid and pack in pipette, then with hand, press above pipette, realize and quantitatively move accurately liquid.
In the utility model, described pipette 1 lower diameter is greater than upper diameter, forms large tripe pipette.
In addition, be provided with handle 6 adding on liquid bath 3 sidewalls, be convenient to mobile whole device.
