Abstract
The invention relates to a pipette gun device comprising a U-shaped gun mounting and a vacuum liquor drainage system. The U-shaped gun mounting comprises springs, buttons and a fixed beam which play a supporting role on two ends; the vacuum liquor drainage system comprises a cross gun mounting cavity, Tip tubes, guide tubes and needle tubes. The buttons are pressed to make the springs contract, and the fixed beam move up and down with the springs. The Tip tubes which are arranged on the fixed beam can move up and down with the fixed beam. A small cavity is arranged in the cross gun mounting cavity, and a plurality of needle tubes on the small cavity are connected with a plurality of lower test tubes through the guide tubes and Tip tubes. When the two buttons on both ends are pressed down and released, liquor in the test tubes below the Tip tubes can rise to the small cavity of the cross gun mounting cavity along the Tip tubes. The device can effectively transport the liquor in the test tubes to a liquor storage device and ensure the pipette effectiveness in the two aspects of accuracy and precision with the characteristics of complete pipette and simple structure.
Description
Technical field
The present invention relates to a kind of pipetting gun device, especially a kind of nucleic acid extraction system pipetting gun device.
Background technology
The principle of work of various liquid-transfering guns is similar to lift pump.All be that a negative pressure is arranged is power, the liquid in extracting on a large scale is gathered together it, moves in the storage vessel.Thereby waste liquid is removed away, stay useful biological tissue, supply experimental study etc.
Find that most liquid-transfering gun is all very simple and easy, and is not thorough when shifting out expense liquid the manufacturing enterprise of domestic liquid-transfering gun being investigated the back, cause having residual, influence the liquid that moves once more; This liquid-transfering gun has added devices such as loculus on the original basis, can all tiny waste liquid stream be pooled together, and is removed away together again, moves liquid not only thoroughly but also effective, succinctly convenient easy to operate, is convenient to promote the use of.
Summary of the invention
The present invention be directed to existing liquid-transfering gun, to move liquid not thorough, the problem of validity difference, a kind of pipetting gun device has been proposed, this device can move on to the liquid in the test tube in the sump assemblies effectively, can guarantee to move the validity of liquid from accuracy and accuracy two aspects, and have the liquid characteristics complete, simple for structure of moving.
Technical scheme of the present invention is: a kind of pipetting gun device, comprise U type gun rack, and also comprise the vacuum drainage system, U type gun rack comprises that two ends play the support of support, spring, button and fixed cross beam; The vacuum drainage system comprises horizontal gun rack chamber, Tip pipe, conduit, needle tubing; Spring, button and fixed cross beam link together and are fixed on the gun rack, button is pressed, spring shrinks, fixed cross beam moves up and down thereupon, the Tip pipe places on the fixed cross beam and can move up and down thereupon, in upper end, horizontal gun rack chamber, be provided with a loculus, having several needle tubings to manage by conduit, Tip with several following test tubes on the loculus links to each other, the two ends button down is pressed, liquid in the test tube when unclamping again below the Tip pipe upwards outwards injects reservoir by conduit in will rising to loculus in the horizontal gun rack chamber along the Tip pipe again.Described Tip pipe adopts the 3ml pipe, and test tube adopts the 10ml plastics tubing.Loculus is positioned at 1/3 place, upper end, horizontal gun rack chamber in the described horizontal gun rack chamber, and internal surface is smooth, is convenient to liquid and is sucked away.
Beneficial effect of the present invention is: this liquid-transfering device, can solve the liquid problem of moving of reagent waste liquid in the nucleic acid extraction, and improve the validity and the accuracy of moving liquid, avoiding the people is move liquid not thorough, improves reagent and moves liquid efficient, guarantees the thoroughness of moving liquid.Therefore, have the accuracy height, move liquid thoroughly, the advantage of decoration structure features simple design, be fit to promote the use of.
Description of drawings
Fig. 1 is a pipetting gun device structural representation of the present invention.
Embodiment
The pipetting gun device structural representation installs and mainly is made up of U type gun rack 2 and eight road vacuum drainage systems as shown in Figure 1; U type gun rack 2 comprises that two ends play the support 1 of support, spring 3, button 4 and fixed cross beam 10, eight road vacuum drainage systems comprise Tip pipe 8, conduit 6, needle tubing 5, spring 3, button 4 and fixed cross beam 11 link together and are fixed on the gun rack, and button 4 is pressed, and spring 3 shrinks, crossbeam 11 moves up and down thereupon, thereby Tip pipe 8 moves up and down on the control crossbeam 11; The two ends button down is pressed, liquid in the test tube when unclamping again below the Tip pipe 8 will be managed 8 along Tip and be risen in the horizontal gun rack chamber 9 of liquid-transfering gun, because lacuna too Da Yi causes refluxing, can not be inhaled into reservoir fully, so we are provided with a loculus 7 at its 1/3 place, upper end, gun rack chamber, there are eight needle tubings 5 to link to each other by conduit 6, Tip pipe 8 on the loculus 7 with eight test tubes, like this, the liquid that at every turn drinks up all can focus on this loculus 7 is convenient to complete sucking-off, and the liquid that is sucked away upwards outwards injects reservoir by conduit.
Tip pipe in the pipetting gun device adopts the 3ml pipe, and test tube adopts the 10ml plastics tubing; Drain pump can suck waste liquid tank with the invisible spectro sample in eight roads by the vacuum system and the eight road separatory volley of rifle fires; The loculus position will be leaned on as far as possible in the horizontal gun rack chamber, and internal surface is smooth, is convenient to liquid and is sucked away.
This device can solve the liquid problem of moving of reagent waste liquid in the nucleic acid extraction, improve the validity move liquid and Accuracy, avoiding the people is move liquid not thorough, improves reagent and moves liquid efficient, guarantees the completeness of moving liquid. Therefore, have degree of accuracy height, move liquid thoroughly, the advantage of decoration structure features simple design, be fit to promote the use of.
