Description

A kind of elution item extracted for full-automatic DNA

Technical field

The utility model relates to elute a field more particularly to a kind of elution item extracted for full-automatic DNA.

Background technique

Currently, forensic dna is examined in criminal investigation field using more and more extensive, except needing to carry out in major criminal cases The acquisition of DNA sample also generally carries out adopting for DNA sample outside extracting and examining in the site inspection that small-sized case is such as stolen Collection, this causes the generation of DNA sample quantity to increase substantially.To cope with such case, a forensic DNA laboratory gradually introduces automation DNA processing equipment meets case and examines needs to improve sample processing capacity.In response to this, my company's independent development Have the full-automatic DNA processing workstation of the functions such as automatic liquid-feeding, manipulator displacement, incubation with heat, centrifugation, people can be substituted Work completes biological material process flow.

To realize the equipment full-automation DNA process flow, matched consumptive material is essential, such as adding The suction nozzle of liquid, the test tube of sample loading, deep-well plates place the test tube etc. of DNA solution after extracting.The work station uses magnetic bar type DNA purification blocks, therefore full-automatic DNA processing workstation is when carrying out DNA purifying, magnetic bead institute adsorption of DNA in eluent into Row desorption and DNA solution preservation be elution item in complete, so elution item structure must with work station structure matching, and Magnetic bead and DNA desorption reaction condition can be met simultaneously, just can ensure that work station completes corresponding automatic operation.

For the specific requirements for meeting full-automatic DNA processing workstation, the utility model provides a kind of delicate structure, operation side Just, it is suitble to the elution item of the batch-automated processing forensic dna sample of full-automatic DNA processing workstation.

Utility model content

In order to solve the problems, such as that elution item and my company full-automatic DNA processing workstation match, the utility model is mentioned A kind of 8 townhouses extracted for full-automatic DNA have been supplied to elute item, including panel, surrounding baffle, be connected on panel 8 Round hole pipe and pipe lid, the hole pipe successively includes aperture, circular through hole, transition through-hole and bottom blind hole from top to bottom.It is this The hole pipe design of segmented can accelerate sample landing, prevent from forming liquid film or drop in hole wall.

In an embodiment of the utility model, it is connected between each pipe lid and surrounding baffle by connection strap, and And it is connected between pipe lid also by connection strap.Structure design makes 8 pipe lids both can be used together or be independently operated, to mention The flexibility used for pipe lid.

Specific embodiment

In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with attached drawing pair The utility model is further detailed.

Referring to Fig. 1, the main structure of the elution item of the utility model includes panel 1, surrounding baffle 2, is connected on panel 8 round hole pipes 3 and pipe lid 4.The corresponding each hole location of elution panel 1 has digital mark, and it is each that differentiation can be accurately positioned Kong Guan primary property can complete the elutions of 8 sample DNAs in full-automatic DNA processing workstation, while improving working efficiency Save a large amount of manpower and time.Moreover, being provided with unique model 5 for first hole location, which positions No. 1 hole location It sets, and is matched with the heating and cooling module corresponding position of full-automatic DNA processing workstation, can be played when placing elution Error correction purpose avoids influence of the mistake to experiment.In addition, being each provided with a protrusion gear on the outside of 8 round hole pipes Plate 6, the DNA sample pollution that liquid film is splashed and thus be may cause when can prevent magnetosheath from moving up and down.

Referring to fig. 2, it is connected between each pipe lid and surrounding baffle by connection strap 42, and passes through connection strap between pipe lid 43 are connected.Such structure design make 8 pipe lids both and can be used together or be independently operated, to assign pipe lid use it is flexible Property, it can be needed according to different experiments and facilitate experimental implementation.In addition, in panel, surrounding baffle and 8 circles being connected on panel It is also provided with reinforcer 7 between the pipe of shape hole, the probability for occurring pyrocondensation hole in product injection moulding process can be reduced, preferably and automatically The heating and cooling module of DNA processing workstation is adapted to.Moreover, by control reinforcer intensity and size, ensure panel and Hole pipe shrinks two longer baffles inwardly slightly, makes it and heating and cooling module is closer matches It closes, it is ensured that elution item will not be moved with magnetosheath during magnetosheath moves up and down.Thermometer hole is designed beside No. 8 hole locations simultaneously 8, usable temperature measuring gauge enters the real time temperature that thermometer hole directly measures full-automatic DNA processing workstation heating and cooling module, really The accuracy of heat preservation degree improves elution efficiency.

Referring to Fig. 3, the hole pipe for eluting item successively includes aperture 31, circular through hole 32, transition through-hole 33, bottom from top to bottom Blind hole 34 and blind via bottom groove 35.Since the internal diameter of bottom blind hole 34 is less than the internal diameter of circular through hole 32, it is washed in addition During de- liquid, the acceleration that fluid sample slides on transition through-hole 33 is greater than the acceleration slid on circular through hole 32, Finally quickly downstream in bottom blind hole 34, preventing fluid sample from forming liquid film, drop since dropping velocity is slow, and then influence Experiment effect.Meanwhile circular through hole side wall 37 devises 1 ° of inclination angle and hole pipe integrally uses sectional design, this makes liquid Body sample is not easy to remain on circular through hole hole wall 37 in transfer process, avoids sample waste.Blind via bottom devises uniqueness Minute recesses 35, it can be ensured that magnetosheath and bottom hole come into full contact with, and when handling minim DNA sample, effluent volume generally exists 20-100ul, the design can ensure that magnetic bead is easier to concussion in small size eluent and mixes, it is fully dispersed and micro- to be conducive to magnetic bead Measure the elution of DNA.

Referring again to Fig. 1 and Fig. 3, in the end Guan Gai, design has an interference structure 41, and in aperture 31 and circular through hole An interference structure 36 is also configured between 32, during closing lid, sealing is played in interference structure 41 and the cooperation of interference structure 36 Effect, it is ensured that minim DNA solution after purification saves under confined conditions at one, and sample is avoided to pollute and evaporate.

It is above that certain exemplary embodiments of the utility model, the common skill of this field are only described by way of explanation Art personnel, can be with a variety of different modes to described reality without departing from the spirit and scope of the utility model Example is applied to be adjusted.
