Abstract
The invention discloses an adjustable quantitative pipette comprising a syringe-shaped liquid absorption cylinder and a plunger matching the liquid absorption cylinder. A liquid inlet is arranged on the liquid absorption cylinder at an end distal to the plunger. A handle is arranged on the plunger at an end distal to the liquid absorption cylinder. A positioning ring is arranged outside a cylindrical surface of the liquid absorption cylinder. Two metal rods are connected outside the cylindrical surface of the plunger. Bent heads are arranged on the two metal rods at ends distal to the plunger handle. A space between straight sections of the two metal rods is larger than the outer diameter of the positioning ring, and a space between bent sections of the two metal rods is smaller than the outer diameter of the positioning ring. According to the adjustable quantitative pipette provided by the invention, with reciprocating movements of the liquid absorption cylinder and the piston of the plunger, liquid fetching and discharging are realized. Piston movement positions are controlled by using the metal rods and the positioning ring, such that liquid quantitation is realized, and liquid absorption is fast. Quantitation operation is not time-consuming, and liquid discharge is also fast, such that the pipette is convenient to use.
Description
Technical field
The present invention relates to a kind of chemical analysis experiment equipment, particularly relate to a kind of quantitative liquid shifter.
Background technology
The laboratory of the units such as industrial production, hospital, scientific research department usually needs the fast quantification pipetting to various test solutions, reagent etc. when carrying out the chemical analysis test, and this just needs a kind of can carrying out quickly and easily quantitatively and the utensil of transfer liquid.
Traditional pipettor tool is glass pipet, be also that everybody is present still at the utensil used, but its imbitition is slow, during quantitative work, be not be exactly few more, often will repeatedly several times could be quantitative, also slow when emitting liquid, make operating process time-consuming longer.Also someone uses a kind of quantitative charger, but that charger is connected on a reservoir, the exit that in use needs to be subject to liquid container to be put into charger, for be not easy to mobile be subject to liquid container also handy another container be subject to after liquid to carry out liquid rotating and move, both easily polluted, also more time-consuming and trouble.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of adjustable quantitative pipettor simple in structure, easy to use.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of adjustable quantitative pipettor, comprise the imbibition cylinder of syringe-like and the plunger coordinated with imbibition cylinder inwall, described imbibition cylinder is provided with inlet away from plunger end, described plunger is provided with handle away from imbibition cylinder end, the described imbibition cylinder face of cylinder is outside equipped with centring ring, described plunger cylinder face is externally connected with two metallic rod, described two metallic rod are provided with elbow away from the plunger handle end, the spacing at described two metallic rod straight section positions is greater than the centring ring external diameter, and the spacing of two metallic rod bend parts is less than the centring ring external diameter.
As preferably, described centring ring can be fixed by screws on the imbibition cylinder face of cylinder.
As preferably, described imbibition cylinder is provided with graduation mark on the face of cylinder.
A kind of adjustable quantitative pipettor of the present invention, utilize the reciprocating motion of the pistons of imbibition cylinder and plunger to realize getting liquid and tapping, utilize the shift position of metallic rod and centring ring control piston to carry out liquid quantitative, make imbitition fast, quantitative work is not time-consuming, emit liquid also fast, do not need the mobile liquid container liquid feeding easily that is subject to, more not needing to be subject to after liquid to carry out liquid rotating with another container moves, avoided pollution, very easy to use, effectively solved industrial production, hospital, in chemical analysis when test, carried out to various test solutions in the laboratory of the units such as scientific research department, the fast quantification pipetting problem of reagent etc., a kind of can carrying out quickly and easily quantitatively and the utensil of transfer liquid.
A kind of adjustable quantitative pipettor of the present invention, material is easy to get, simple in structure, with low cost, can produce in batches, and easy to use, do not need training to use, can meet the needs of the laboratory of the units such as industrial production, hospital, scientific research department to the fast quantification pipetting of various test solutions, reagent etc. fully.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the structural representation of a kind of adjustable quantitative pipettor of the present invention.
Wherein, Reference numeral: 1 for the imbibition cylinder, and 2 be plunger, and 3 is the inlet on the imbibition cylinder, and 4 is plunger handle, and 5 is centring ring, and 6 is metallic rod, 7 end bends that are metallic rod, and 8 is screw, 9 is the graduation mark on the imbibition cylinder.
The specific embodiment
Disclosed all features in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this specification, unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is,, unless special narration, each feature is an example in a series of equivalences or similar characteristics.
As shown in Figure 1, a kind of adjustable quantitative pipettor of the present invention, comprise the imbibition cylinder 1 of syringe-like and the plunger 2 coordinated with imbibition cylinder inwall, the imbibition cylinder is provided with inlet 3 away from plunger end, plunger is provided with handle 4 away from imbibition cylinder end, the imbibition cylinder face of cylinder is outside equipped with centring ring 5, the plunger cylinder face is externally connected with two metallic rod 6, two metallic rod are provided with elbow 7 away from the plunger handle end, the spacing at two metallic rod 6 straight section positions is greater than centring ring 5 external diameters, and the spacing at two metallic rod elbow 7 positions is less than centring ring 5 external diameters.
As shown in Figure 1, in a kind of adjustable quantitative pipettor of the present invention, centring ring 5 can be fixed on imbibition cylinder 1 face of cylinder by screw 8, and slip and stationary positioned circle 5 are all very convenient like this.In order to facilitate reading, the imbibition cylinder is provided with graduation mark 9 on 1 face of cylinder.
As shown in Figure 1, when a kind of adjustable quantitative pipettor of the present invention is used, amount according to the liquid that will pipette, movably centring ring 5 moves to imbibition cylinder 1 corresponding scale place, screw screw 8, movably centring ring 5 is fixing, then the bottom of plunger 2 is pressed onto to the bottom of imbibition cylinder 1, the inlet of imbibition cylinder 13 is put under the liquid level of the liquid that will pipette, stay column plug 2 makes progress, liquid enter in imbibition cylinder 1, when plunger 2 moves upward to corresponding height, elbow 7 part of metallic rod 6 bottoms of rigidity is subject to the stopping of centring ring 5 of having fixed with screw 8 and can not moves upward again, liquid no longer enter in imbibition cylinder 1, realized quantitatively pipetting the purpose of liquid, guaranteed the accuracy of the amount of the liquid that quantitatively pipettes.Only the liquid pipetted need be pressed into and got final product by liquid container after drawing.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
