The pipette tips of row are exposed in operating space, can effectively reduce the probability of other pipette tips pollution, and further reduce experiment sample
The probability of pollution, so as to improve the efficiency of experiment.
Technical solution：The anti-pollution pipettor gun head cartridge of the utility model, including cassette bottom, it is arranged on turning on the box body
It is rotatable box lid, the parallel multiple sliding slots being arranged in box body, the sliding block that is arranged in the sliding slot and can slide wherein, parallel
More springs being arranged on the inside of box lid, sliding slot both sides are provided with the partition plate in box body, are provided with and engrave on the partition plate
Unoccupied orbital, sliding block rear both ends are equipped with two fixing devices, and described two fixing devices are respectively embedded into the hollow track of both sides,
Spring is connected respectively a fixing device.
Further, in the utility model, the width of sliding slot is less than pipette tips bottom annular structure diameter, avoids pipette tips from crashing into
Tray interior, box body front end are equipped with a card slot, and box lid leading edge is equipped with a switch, by the cooperation of card slot and switch, make box lid with
Box body closely connects.
Further, in the utility model, front end of lid is equipped with bore and is passed through slightly larger than the through hole of pipette tips bore and covering
The baffle of closure can simultaneously be opened by perforating.
Further, in the utility model, box body is provided with 8 sliding slots, and every sliding slot can accommodate 8 pipette tips, pipette tips
It can be moved back and forth along sliding slot, 16 springs are set in box lid.
The utility model construction is exquisite, and easy to operate, popularization easy to spread, effectively solves molecular biology in clinical position
The problem of pipette tips pollute in experiment.
The operating procedure of the utility model is：
Open the lid, spring is in maximum tension state, box lid is closed after loading pipette tips.As needed, it is conventional to carry out
High pressure steam sterilization；
After opening baffle, pipette tips can be inserted into by the through hole of front end of lid.Normal experiment uses pipette tips；
After experiment, baffle is closed.After pipette tips use, recharge pipette tips and sterilize, to reuse.
Beneficial effect：Compared with prior art, the utility model has the following advantages：
(1) traditional pipettor gun head box main body includes box lid, cassette bottom and pipette tips supporting plate, when box lid is opened, positioned at rifle
Pipette tips on head splint are both exposed in operating space, are vulnerable to pollution.The utility model solves the problems, such as this, in operating process
Only most front-seat pipette tips are exposed in operating space, at utmost avoid the pollution of pipette tips.
(2) pipette tips propulsion device automatically can push to pipette tips most front-seat, avoid cuff in traditional experiment operation from meeting it
The situation of his pipette tips, and at utmost prevent splash, fall into pollutant, effectively reduce the probability of pollution.
(3) the utility model construction is exquisite, and simple in structure, easy to operate, cost is relatively low, is used easy to popularize.
