Abstract
The utility model discloses a pipette, relating to experimental pipetting devices. The pipette comprises a pipette body and a rubber hose sleeved on the upper end of the pipette, wherein a flow regulator is mounted on the rubber hose. The utility model has the following beneficial effects that: the flow regulator is capable of continuously regulating the gap of the rubber hose from zero to the diameter of the rubber hose, thus guaranteeing the regulating accuracy of the liquid level and having the advantages of good safety, simple structure and convenient operation.
Description
Technical field
The utility model relates to a kind of test pipettor tool, specifically is a kind of pipette.
Background technology
At present, the pipette of experiment or check usefulness mostly is the straight shape glass tube of up/down perforation, insert pipette upper end mouth of pipe imbitition by rubber pipette bulb during use, because the effect of pipe inside and outside differential pressure, liquid is promptly entered in the pipe by pipette lower end sharp-crested, when the intraluminal fluid scale of construction is enough, takes away rubber pipette bulb and blocks the mouth of pipe with finger, slowly reduce liquid level to the amount that needs by moveable finger, move to again in the vessel that will add.The problem that exists is: operate not easyly, get liquid measure and be not easy to control.Move away to finger at rubber pipette bulb and to block in the process, the liquid level in the pipe descends and to cause quantity not sufficient rapidly easily; Adopt the moveable finger mode to regulate too much liquid, also be difficult to control, need skillfully operation.Patent 200620029828.0 discloses a kind of pipette, connect one section sebific duct in the pipe upper end, be plugged with glass marble in the pipe, during work, hand is pinched the glass marble position of sebific duct, air communication cross produce because of the sebific duct inner wall deformation and ball between the slit enter pipette because air inflow is very little, reagent is very slow along the speed that the pipette endoporus rises, and it is controllable that uptake is become.Shortcoming is, needs hand pinching glass marble during imbitition always, bring inconvenience, and the precision that liquid level is regulated is not high enough.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of pipette, can guarantee that precision, the security of liquid level adjusting is good, simple in structure and easy to operate.
The utility model is realized with following technical scheme: a kind of pipette, comprise body and the sebific duct that is enclosed within its upper port, and a flow adjuster is installed on sebific duct.
The beneficial effects of the utility model are: flow regulator can be realized the slit of sebific duct by the zero continuous adjusting to sebific duct caliber size, thereby regulates the interior liquid level of body by regulating air inflow, the precision height, and security is good, simple in structure and easy to operate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of flow regulator.
Among the figure: 1, sebific duct, 2, flow regulator, 2-1, regulate roller, 2-2, race, 2-3, oblique rail, 3, body.
The specific embodiment
As shown in Figure 1, pipette has a body 3, is with a sebific duct 1 in the upper port of body 3, and flow regulator 2 is installed on the sebific duct 1; The length of sebific duct 1 is greater than the length of flow regulator 2.
As shown in Figure 2, in the present embodiment, flow regulator 2 has adopted the medical widely used infusion flow adjuster of.It has a wedge shape race 2-2 and is installed in the race and the adjusting roller 2-1 that can roll along the oblique rail 2-3 of race.Sebific duct 1 is loaded between the perpendicular wall in the right angle of regulating roller 2-1 and wedge shape race 2-2.
During work, rubber pipette bulb is installed,, is made the slit of sebific duct 1 suitable by the adjusting roller 2-1 in the rolling flow regulator in the upper port of sebific duct 1.When the absorption liquid measure is enough, slide into bottom regulating the oblique rail 2-3 of roller 2-1 along race, this moment, sebific duct 1 was closed, and it is stable that the intraluminal fluid scale of construction keeps, and takes off rubber pipette bulb.With the slow with one's hands slidable adjustment roller 2-1 that makes progress slowly,, thereby guarantee the precision that liquid level is regulated because flow regulator can be realized the slit of sebific duct 1 by the zero continuous adjusting to sebific duct 1 caliber size.
Claims (3)
1. pipette comprises body (4) and is enclosed within the sebific duct (1) of its upper port, it is characterized in that: go up at sebific duct (1) flow regulator (2) is installed.
2. pipette according to claim 1 is characterized in that: described flow regulator (2) comprises a wedge shape race (3) and is installed in the race (3) and the adjusting roller (2) that can roll along the oblique rail (2-3) of race (3).
3. pipette according to claim 1 is characterized in that: the length of sebific duct (1) is greater than flow regulator (2) length.
