Description
Technical field
It the utility model is related to microbial apparatus technical field, more particularly to pipettor cleaning device.
Background technology
Pipettor is usually used in that laboratory is a small amount of or micro liquid pipettes, and the conventional pipettor specification in laboratory is different,
From several ml to tens ml specifications, although the multi-size of pipettor, storage liquid space be all it is very narrow and small,
Especially micropipette, its inner space are cleaned using exterior washings instrument, and many cleanings can be brought difficult, do not utilized
Recycle, cause to waste.If do not washed clean clearly, be likely to result in using in same pipettor different liquids composition it is mixed
It is miscellaneous, bring error to experiment.
The conventional cleaning method in laboratory is first to be washed with water at present, if carrying liposoluble substance not soluble in water etc.,
Acid solution can be added or alkali lye is soaked.But simple immersion still can not carry out good rush to the inwall of pipettor
Rinse, have material residual, so needing a kind of efficient pipettor cleaning device badly at present.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided it is a kind of it is new, flush efficiency is high, energy
The device effectively rinsed to pipettor inwall.
The utility model is achieved through the following technical solutions：
A kind of pipettor cleaning device, including liquid storage cylinder, piston, connecting tube, air bag, propulsion tube and joint, liquid storage cylinder one
End has protuberance, and protuberance has opening, and protuberance opening has interface covered with macromolecule membrane, the liquid storage cylinder other end,
Interface connects with connecting tube, and the protuberance opening for being covered with macromolecule membrane is detachably connected with joint, and joint is used to connect liquid relief
Device.
Further, it is vacuum state in liquid storage cylinder.
Further, macromolecule membrane is made of polylactic acid film.
Further, there is dividing plate in liquid storage cylinder, dividing plate is between piston and air bag.
Further, dividing plate is flexibly connected with liquid storage cylinder.
Further, there is compression cylinder and trigger unit in propulsion tube.
Further, trigger unit includes press section and pushing ram, and press section is fixedly connected and is located at one end of pushing ram
Promote the outside of cylinder.
Further, pushing ram also includes limiting section, is removably clamped in the periphery of pushing ram.
Pipettor cleaning device small volume and less weight provided by the utility model, it is workable, and can be carried to pipettor inwall
For more powerful impulsive force, it can guarantee that inner wall washing is clean.
Brief description of the drawings
Fig. 1 is the schematic diagram of pipettor cleaning device.
Embodiment
The utility model provides a kind of pipettor cleaning device, as shown in figure 1, it includes liquid storage cylinder 1, piston 2, connecting tube
3rd, air bag 4, propulsion tube 5 and joint 6.Liquid storage cylinder one end has protuberance 11, and the other end has interface 12, the end of protuberance 11
With opening, protuberance distal opening is used to draw cleaning fluid, and protuberance 11 connects with the insertion of joint 6, interface 12 and connecting tube 3
It is connected.Protuberance distal opening is made covered with macromolecule membrane, macromolecule membrane of polylactic acid film material, meets solution
It can dissolve.Protuberance distal opening is detachably connected with joint, joint other end connection pipette tip.Joint is by elastomeric material
It is made, the pipette tip of different size can be socketed.The one end of connecting tube 3 is goed deep into liquid storage cylinder being tightly connected with air bag 4, another
End is goed deep into propulsion tube being tightly connected with compression cylinder.
Include compression cylinder 7 and trigger unit 8 in propulsion tube 5.Propulsion tube includes both ends open 51 and 52, and connecting tube is from opening
51 enter connection compression cylinder.Trigger unit is goed deep into propulsion tube through propulsion tube one end open 52, and with the switch of compression cylinder
Alignment, by promoting trigger unit into propulsion tube body, trigger unit can touch the switch of compression cylinder so that compression cylinder is touched
Hair.
Before use, being vacuum state in liquid storage cylinder body, cylinder protuberance distal opening is immersed in cleaning fluid, opening is thin
Film is dissolved, and cleaning fluid is pressed into cylinder by atmospheric pressure, promotes piston to be moved to the direction of interface 12.Liquid storage cylinder sucks cleaning fluid
Afterwards, air bag is in contraction state.Compression cylinder be triggered after by connecting tube to airbag aeration so that air bag volume increases, and pushes away
Piston, air bag instantaneous expansion promotes piston, and then promotes cleaning fluid to be poured from joint in pipette, is caused to pipette side wall
Larger impact, pipette inside is effectively cleaned.
Further, dividing plate 9 is also included in liquid storage cylinder, it is tabular, movably in liquid storage cylinder body, positioned at work
Plug and air bag therewith between so that air bag is isolated with piston, is advantageous to the abundant expansion of air bag.There is through hole, for connection on dividing plate
Pipe through.
Under original state, air bag is compression, and for dividing plate 9 clampingly between air bag and piston, the area of dividing plate is smaller
In the cross section of liquid storage cylinder, when air bag expands, dividing plate is promoted piston so that living by the active force of air bag from all directions
Uniform force is filled in, realizes the purpose of cleaning fluid in good impact liquid storage cylinder body.In the present embodiment, dividing plate is connected with air bag, energy
Enough with air bag associated movement.In other embodiments, stopping means can be set in cylinder, when air bag expands, dividing plate is pushed out,
Move to and be prevented from further moving when contacting with limiting section, now cleaning fluid has been pushed out liquid storage cylinder.
In the present embodiment, trigger unit 8 also includes press section 81 and pushing ram 82, and one end fixation of press section and pushing ram connects
The outside for promoting cylinder is connect and is located at, pushing ram gos deep into cylinder through propulsion cartridge openings 52, the other end and pressure of pushing ram
Contracting switching cylinder aligns, and the periphery of cartridge openings 52 can have sealing ring so that the periphery of pushing ram is with promoting cartridge openings 52
Between it is in sealing contact.Also including limiting section 83 on pushing ram 82, it is removably clamped in the periphery of pushing ram, and positioned at pressing
Between portion and the other end for promoting cylinder 5 so that the other end of pushing ram does not contact with the switch of compression cylinder.When being not used,
Due to the setting of limiting section so that compression cylinder can not be triggered, it is necessary in use, unload limiting section, tactile so as to promote
Hair portion.
Pipettor cleaning device small volume and less weight provided by the utility model, it is workable, and can be carried to pipettor inwall
For more powerful impulsive force, it can guarantee that inner wall washing is clean.
