Abstract
The utility model discloses a laboratory solution moving device. The laboratory solution moving device consists of a solution moving pipe, wherein the solution moving pipe comprises a glass pipe body, a rubber pipe and a glass ball, wherein an upper end port of the glass pipe body is thicker than other parts of the glass pipe body and protrudes outwards; the rubber pipe is sleeved on the upper end port of the glass pipe body; the glass ball is arranged inside the rubber pipe; and the size of the glass ball corresponds to the inner diameter of the rubber pipe. The laboratory solution moving device can control opening and closing of the solution moving pipe and operate and control falling and stopping of a liquid surface of a solution freely, so that the experimental operation is facilitated.
Description
Technical field
The utility model relates to a kind of laboratory equipment, relates in particular to a kind of experiment liquid-transfering device.
Background technology
In the prior art, the most frequently used liquid-transfering device is a pipette in the laboratory, mainly is used for accurately pipetting the solution of certain volume.When using pipette to pipette solution, generally be with ear washing bulb solution upwards to be inhaled earlier, block the suitable for reading of pipette with finger again, the decline through finger liquid level in the folding of the mouth of pipe is controlled and stopping.The switch of the wayward pipette of this method, the decline of uncontrollable liquid level and stopping to be prone to cause actual draw solution amount more on the low side than purpose amount; Need repeat to draw; Or the draw solution amount is too much, needs elapsed time to wait for that liquid level descends, and has brought bigger trouble to experimental implementation.
The utility model content
The utility model technical problem to be solved is: provide a kind of and can freely control the pipette switch, control liquid level of solution descend and stop, the laboratory liquid-transfering device of handled easily.
The technical scheme that its technical problem of the utility model solution is taked is: the laboratory liquid-transfering device of the utility model is made up of pipette; Said pipette comprises canals of stilling, rubber tube, glass marble, and the port of canals of stilling is thicker than other part of canals of stilling, outwards heaves; Said rubber tube is placed in the port of canals of stilling; Said glass marble is arranged in the rubber tube, and size is corresponding with the internal diameter of rubber tube.
The beneficial effect that the utility model technical solution problem is obtained is: the laboratory liquid-transfering device of the utility model; Comprise canals of stilling, rubber tube, glass marble, rubber tube is placed in the canals of stilling upper end, in rubber tube, is provided with glass marble; With ear washing bulb the solution suction line in graduation mark above after; Squeeze the glass marble in the rubber tube through thumb and forefinger, the decline of stable control liquid level and stopping to make things convenient for experimental implementation.
Description of drawings
Fig. 1 is the profile of the utility model,
Wherein, 1-canals of stilling, 2-rubber tube, 3-glass marble, 4-port.
The specific embodiment
Show that like Fig. 1 the laboratory liquid-transfering device of the utility model is made up of pipette, said pipette comprises canals of stilling, rubber tube, glass marble; The port of said canals of stilling is thicker than other part of canals of stilling, outwards heaves; Said rubber tube is placed in the port of canals of stilling; Said glass marble is arranged in the rubber tube, and size is corresponding with the internal diameter of rubber tube.
Said rubber tube length is 4cm to 10cm.
The laboratory liquid-transfering device of the utility model is when pipetting solution; Squeeze the glass marble in the rubber tube with thumb and forefinger earlier; The top of graduation mark in the solution suction line, unclamp two fingers with ear washing bulb, remove ear washing bulb; And then squeezing the glass marble of rubber tube, the control liquid level slowly drops to the graduation mark of appointment.
Claims (2)
