Description
Technical field
The utility model belongs to technical field of medical instruments, more particularly to a kind of DNA retracting devices.
Background technology
Adsorption column is the common experimental articles for use in molecular biology experiment, is even more to use in rapid extraction plasmid method
Product, centrifuge need to be used for multiple times using process.But various problems and potential hazard, subject matter are often accompanied by the use of centrifuge
As described below：1. during use, do not cover tightly if there is test tube cap or without test tube cap, be put into or take out accidentally, or place uneven
Weighing apparatus, sample is easily caused situations such as test tube breakage and overflows and causes centrifuge to be contaminated, therefore centrifuge usually from pathogen
The high risk zone of concentration, huge bio-safety hidden danger be present.2. centrifuge can produce largely during running at high speed
Aerosol, these samples all should be considered as infectious sample, and the health of reviewer is threatened there is potential；Meanwhile from
Dust or dirt in scheming can also produce corresponding aerosol during running at high speed, breathing, digestion to human body, god
It can be had an impact through system.3. centrifuge symmetrical holes load is unbalanced, centrifugal speed is too fast, and test tube selects improper, test tube sleeve
In have a debris, rotary head deformation, the reason such as bearing wear can cause the test tube of centrifugal process to burst, even whole centrifuge
Blast, detonation.Produce a large amount of aerosols or even more serious laboratory accident can be produced.4. multiple differential centrifugation causes a large amount of realities
Test time consumption.In order to solve the above problems, with regard to adsorption column using need multiple high speed centrifugation the characteristics of, develop a set of alternative
The device of centrifugal filtration step is significant.
Utility model content
The purpose of this utility model is to provide a kind of DNA safe and efficient, cost is cheap, easy to operate, versatile
Retracting device.
In order to solve the above technical problems, DNA retracting devices provided by the utility model, including sucker and some absorption
Post, formed with closed adsorbent chamber, the sucker top surface is provided with to match for its inserting the suction cup interior with the adsorption column
Jack, the jack bottom connected with the adsorbent chamber, and the adsorbent chamber is provided with gas outlet, and the gas outlet is inhaled with negative pressure
Lead device connects.
Further, the adsorbent chamber is in bowl-type, and the gas outlet is opened in the bottom of the adsorbent chamber.
Further, described DNA retracting devices also include some blanking covers to match with the jack.
DNA retracting devices of the present utility model can handle multiple samples simultaneously, simple and effective, versatile；It is alternative from
The heart filters, and can solve the shortcomings that centrifuge speed does not reach requirement, and safe operation is effective；Sucker can repeatedly use, into
This is cheap.

Fig. 2 is side view of the present utility model；
Wherein：1- suckers；2- adsorption columns；3- adsorbent chambers；4- jacks；5- gas outlets；6- conduits；7- vacuum extractors；8-
Blanking cover.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1-2, DNA retracting devices provided by the utility model, including sucker 1 and some adsorption columns 2, institute
State sucker 1 and be internally formed closed adsorbent chamber 3, the top surface of sucker 1 is provided with its inserting of the confession to match with the adsorption column 2
Jack 4, the bottom of jack 4 connects with the adsorbent chamber 3, and the adsorbent chamber 3 is in bowl-type, in the bottom of the adsorbent chamber 3
Provided with gas outlet 5, the gas outlet 5 is connected by conduit 6 with vacuum extractor 7, if described DNA retracting devices also include
The dry blanking cover 8 to match with the jack 4.
It is described as follows using the experimentation of above-mentioned DNA retracting devices：
Adsorption column 2 equipped with liquid is inserted in jack 4, the outer tube wall of adsorption column 2 is bonded with the inwall of jack 4, does not place
The sealing blocking of blanking cover 8 of jack 4 of adsorption column, adsorbent chamber 3 is vacuumized using vacuum extractor 7 so as to while complete multiple suctions
The filtering of the waste liquid of attached column 2.
