Abstract
It the utility model is related to a kind of test apparatus, more particularly to a kind of Novel pipette, mainly include pipette lower part, pipette top, pipette branch pipe, air bag, syringe needle, rubber sample plug, connecting tube, rotary-piston one, rotary-piston two and separate sample plug.Pipette tube body is divided into two parts up and down, and the wherein side of pipette upper portion pipe body carries the pipette branch pipe of rotary-piston two, and the lower end on pipette top is closely coupled with separating sample plug by top nut；The air bag is connected by the connecting tube with rotary-piston one with syringe needle；The syringe needle is through rubber sample plug and separates sample plug insertion pipette lower part.The Novel pipette is simple in structure, easy to operate, can be with liquid relief and liquid storage, and avoids the problem that the inaccuracy of ear washing bulb operation in the prior art and the excessive corrosion ear washing bulb of liquid suction.
Description
Technical field
It the utility model is related to a kind of test apparatus, and in particular to a kind of Novel pipette.
Background technology
Pipette is the test apparatus for accurately measuring the solution of certain volume, is common tester in biochemical test
Device.Common pipette is a slender glass tube, and lower end is sharp mouth shape, and tube body has uniform scale.In an experiment, pipette needs
It is used cooperatively with ear washing bulb, by extruding ear washing bulb by the volume in solution suction line, sucking liquid and the extruding journey of ear washing bulb
Spend related, when extruding degree is excessive, the liquid of suction may overflow into ear washing bulb, may corrode ear washing bulb, and extruding degree is not
When enough, liquid level does not reach requirement, it is necessary to carry out secondary operation.Existing ear washing bulb coordinates imprecision with pipette, and liquid, which enters, to be moved
After liquid pipe, if upper port finger is not stifled tight, to re-operate.
The content of the invention
To solve the above problems, the utility model provides a kind of Novel pipette simple in structure, easy to operate.
The utility model is realized by scheme described below：A kind of Novel pipette, including syringe needle, rubber sample plug,
Connecting tube, rotary-piston one, air bag, pipette lower part, separate sample plug, top nut, pipette top, rotary-piston two,
Pipette branch pipe.Pipette tube body is divided into two parts up and down, and there is the shifting with rotary-piston two in wherein pipette top side
Liquid pipe branch pipe, the lower end on pipette top are closely coupled with separating sample plug by screw thread；The air bag with rotation by living
The connecting tube of plug one is connected with syringe needle；The syringe needle is through rubber sample plug and separates sample plug insertion pipette lower part.
The air bag 5 is the spherical hollow space air bag that radius is 2.5cm, and lower section length of the connection with rotary-piston 1 is
5cm, the connecting tube 3 that radius is 1cm, after air sac pressing, can adjust air bag recovery extent by rotating rotary-piston one.
The rubber sample plug 2 of the long 1cm and pipette upper port diameter are 1cm, can be combined closely, syringe needle 1 is extracted
Afterwards, 2 pin hole of rubber sample plug disappears, and liquid will not flow out, and can store liquid.
The separation sample plug 7 and pipette lower part 6,9 diameter of pipette top are 0.8cm, and pipette lower part 6 is grown
25cm, 9 long 5cm of pipette top, separate 7 a length of 2cm of sample plug, which can prevent liquid from crossing sample plug.
The length of the pipette branch pipe 11 is 4cm, a diameter of 0.8cm, can be adjusted by rotating rotary-piston 2 10
Liquid level.
The utility model avoids the inaccuracy for coordinating imprecision and operation of ear washing bulb and pipette, and liquid corrosion is washed
The problem of ear ball.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and detailed description.
Fig. 1 is the utility model overall structure diagram.
Fig. 2 is cell parts structure diagram.
Fig. 3 is pipette part-structure schematic diagram.
Description of symbols：Syringe needle 1, rubber sample plug 2, connecting tube 3, rotary-piston 1, air bag 5, pipette lower part 6, separation
Sample plug 7, top nut 8, pipette top 9, rotary-piston 2 10, pipette branch pipe 11.
Embodiment
As shown in Figure 1, the utility model consists of the following parts：
Syringe needle 1, rubber sample plug 2, connecting tube 3, rotary-piston 1, air bag 5, pipette lower part 6, the spiral shell of glass holey
Line separates sample plug 7, top nut 8, pipette top 9, rotary-piston 2 10, pipette branch pipe 11
Separation 7 upper outside of sample plug has screw thread, aperture and pipette lower part 6, the pipette top 9 of the sample plug
Aperture match, sample plug 7 is separated during use can fill in the hole of pipette lower part 6, make separation sample plug 7 and pipette
Lower part 6 is attached.The aperture of top nut 8, screw thread are with separating the aperture of sample plug 7, screw thread coincide, and top nut 8 can be with
It is attached by rotation with separating sample plug 7.The aperture of rubber sample plug 2 and the aperture size one of 9 port of pipette top
Cause, can combine closely.Connecting tube 3 of 5 lower end of the air bag connection with rotary-piston 1, connecting tube 3 are connected with syringe needle 1, the company of opening
Rotary-piston 1 in adapter 3, rotary-piston 1 is closed after extruding gasbag 5, and syringe needle 1 is penetrated rubber sample plug 2, opens rotation
Plug 1 is turned a work, is drawn liquid into pipette, rotary-piston 1 is closed after pipetting liquid, syringe needle 1 is extracted into rubber sample plug
2.Rubber sample plug 2 is combined closely with pipette, and liquid will not flow out pipette.When sucking liquid excess, separate sample plug 7
It can prevent liquid from crossing sample plug, the connecting tube 3 with rotary-piston 1 of certain length avoids liquid corrosion air bag 5.When
When suction liquid volume is inadequate, the air bag 5 for being connected with connecting tube 3 can be extracted together with syringe needle 1, operated again.Pipette branch pipe
11, rotate the liquid volume that rotary-piston 2 10 adjusts suction.
, can be by syringe needle 1, rubber sample plug 2, connecting tube 3, rotary-piston 1, pipette lower part 6, separation after experiment
Sample plug 7, pipette top 9, rotary-piston 2 10, pipette branch pipe 11 are split, are cleaned, and are used easy to next time.
