Abstract
A kind of novel rubber pipette bulb of the utility model is made of air bag, glass stopper, U-tube, glass tube, liquid storing part, sharp mouth structure；The glass stopper is internally provided with U-tube, the external lower end of the glass stopper is equipped with helicitic texture, the upper inside wall of the glass tube is equipped with helicitic texture, the glass stopper and glass tube are assembled by helical structure, the Air sac cover is allowed to combine closely with the outer surface of glass stopper in the outside of glass stopper.The utility model provides a kind of novel rubber pipette bulb for overcoming the excessive reason of absorption that drawn liquid reagent is made to enter air bag.
Description
Technical field
The utility model is related to a kind of novel rubber pipette bulbs, belong to experimental instrument field.
Background technology
Rubber pipette bulb is often used during carrying out biology and chemical experiment and pipette carries out transfer liquid reagent, and
Rubber pipette bulb is not easily controlled the soakage for being transferred liquid in use, often makes to be drawn due to drawing excess
Liquid reagent enter air bag and corrosiveness generated to air bag, substantially reduce the service life of rubber pipette bulb, give experimental implementation
Bring many inconvenience.
Invention content
The purpose of the utility model is to overcome the deficiencies of original technology, provide a kind of novel rubber pipette bulb.
A kind of novel rubber pipette bulb of the utility model, by air bag, U-tube, glass stopper, glass tube, liquid storing part and sharp mouth structure
Composition；The glass stopper is internally provided with U-tube, and the external lower end of the glass stopper is equipped with helicitic texture, the glass tube
Upper inside wall is equipped with helicitic texture, and the glass stopper and glass tube are combined closely by helical structure, and the Air sac cover is in glass
The outer upper ends of plug are allowed to combine closely with the outer surface of glass stopper.
The utility model is also characterized by：The air bag, which is mounted on the glass stopper for being internally provided with U-tube, passes through spiral
Structure is combined with glass tube and connect.
U-tube inside the glass stopper can prevent in draws fluid air bag, and can prevent from evaporating into gas
In capsule, the service life of air bag is extended.
The liquid storing part can prevent liquid to be drawn into air bag, improve the service life of air bag.
Description of the drawings
Fig. 1 is that a kind of structure of novel rubber pipette bulb of the utility model splits schematic diagram.
Fig. 2 is a kind of overall structure figure of novel rubber pipette bulb of the utility model.
In figure, 1. air bags, 2. glass stoppers, 7. outer wall threads, 6.U type pipes, 3. glass tubes, 8. inner threads, 4. liquid storing parts,
5. sharp mouth.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of novel rubber pipette bulb of the utility model is by air bag 1, glass stopper 2, U-tube 6, glass tube 3, liquid storing part 4, sharp mouth 5
Structure composition, the glass stopper 2 are internally provided with U-tube 6, and the external lower end of the glass stopper 2 is equipped with 7 structure of outer wall thread,
The upper inside wall of the glass tube 3 is equipped with 8 structure of inner thread.
A kind of novel rubber pipette bulb of the utility model it is specific assembling use process is as follows：Air bag 1 is sleeved on glass stopper 2 first
