Description
Technical field
The utility model relates to equipment of chemical industry more particularly to a kind of pipettes.
Background technique
Pipette is that one kind measures formula instrument, for accurately removing the solution of certain volume.Pipette is that a centre has
The slender glass tube of one enlargement, lower end are sharp mouth, are carved with a graduation mark as volume indicator at the neck of upper end.Use liquid relief
When pipe pipettes solution, the liquid relief tip mouth after rinse is placed under liquid level of solution, appropriateness squeezes ear washing bulb and solution is drawn to upper end
It on pipe graduation mark, withdraws after ear washing bulb and blocks upper pipes nozzle with right hand index finger rapidly, pipette is kept vertical, keeps view
Line and graduation mark are horizontal, slightly unclamp index finger, flow out solution in pipe slowly from sharp mouth, when liquid level is Chong Die with scale, by tight
Right hand index finger completes constant volume, i.e., accurately pipettes the solution of certain volume.
It is pipetted in the operating procedure of solution using above-mentioned pipette, in constant volume, there are certain subjectivities, can not keep away
There is slight error with exempting from, to influence experimental result；And constant volume operation is not easy to control, once liquid level lower than if graduation mark
Must draw solution again, waste time；In addition, constant volume operation during the entire process of the right hand must be always maintained at pipette hang down
Directly, right hand index finger will push down upper pipes nozzle always, be possible to influence the accurate of constant volume in the process if having other to operate
Property.
Utility model content
The utility model is provided for error is easy to appear and problem inconvenient for operation in the operation of existing pipette constant volume
A kind of pipette.
The technical solution that the utility model solves above-mentioned technical problem is as follows: a kind of pipette, including outer cover, liquid storage bubble,
Upper bend pipe and lower bend pipe, which is characterized in that
The outer cover and liquid storage bubble are hollow spheroid, and the outer cover long axis and the liquid storage steep long axis weight
Folded, the liquid storage bubble is located at the outer cover center；
Described upper bend pipe one end is steeped lower vertex with the liquid storage and is connected to, and part of the upper bend pipe in the outer cover is arc
Shape bending, the upper bend pipe other end are stretched out from vertex on the outer cover, and extension is straight tube, and straight tube top is flat mouth；
Described lower bend pipe one end is steeped upper vertex with the liquid storage and is connected to, and part of the lower bend pipe in the outer cover is arc
Shape bending, the lower bend pipe other end are stretched out from vertex under the outer cover, and extension is straight tube, and straight tube top is sharp mouth；
The arc-shaped bend of the arc-shaped bend of the upper bend pipe and the lower bend pipe is located at the liquid storage bubble symmetrical two
Side, described being covered with one group symmetrically pinches slot outside.
The beneficial effects of the utility model are: the lower vertex that the utility model steeps upper bend pipe and lower bend pipe with liquid storage respectively
It is connected to upper vertex, forms linker, the solution of fixed volume can be measured without manual constant volume, people when avoiding manual constant volume
Solution is housed without upper pipes nozzle is pushed down with index finger always when the utility model measures solution for the error that factor generates
Afterwards still can it is of short duration placement and carry out other operations, it is easy to use.
Further, the arc-shaped bend highest point of the lower bend pipe be opening under to bent angle.
Beneficial effect using above-mentioned further scheme is: lower bend pipe arc-shaped bend highest point is curved equipped with what Open Side Down
Angle, can avoid constant volume when due to siphonic effect by liquid storage steep in solution be sucked out and generate error.
Further, the outer cover is equipped with air-bubble level, and the air-bubble level, which is located at, a certain described pinches the upper of slot
Side.
Beneficial effect using above-mentioned further scheme is: being equipped with air-bubble level, it is ensured that pipette is in vertical
State, liquid level is not in inclination and influences to remove the volume of solution when constant volume.
When preparing the utility model, according to pipette volume can first individually designed liquid storage bubble, upper bend pipe and lower bend pipe, combination
Repeatedly debugging constant volume can be prepared by the higher pipette of precision afterwards.
After the liquid for drawing certain volume using the utility model, keeps pipette horizontal, resist upper bend pipe with ear washing bulb
Flat mouth, slight squeeze blow out liquid, repeat 2-3 time until lower bend pipe point mouth at no liquid drip i.e. completion certain volume liquid
Pipette.
