Description

It is a kind of that frozen dual-purpose explosion stack is centrifuged

Technical field

This utility model is related to biological technology application, be applied especially to DNA/RNA extraction and frozen one kind from The frozen dual-purpose explosion stack of the heart.

Background technology

Centrifuge tube is one of the most frequently used equipment in biotic experiment, and in many biotic experimenies, such as DNA/RNA's carries Take, be required to use centrifuge tube in the collection of cell and antibacterial.Cryopreservation tube be for preserve DNA/RNA, cell/antibacterial, tissue, A kind of equipment, among being often stored in refrigerator or liquid nitrogen.

, with cryopreservation tube as use is different, in design, difference is also than larger for existing centrifuge tube.First adopt in general experiment Centrifuge tube collects target substance, again the material in centrifuge tube is transferred in cryopreservation tube when needing frozen.But have perhaps Polymolecular is tested, and operating procedure is more and object mass considerably less (being less than tens microlitres), reuses liquid relief in this case Device carries out the transfer of target substance and can cause damage again, for fine molecule experiments unfortunately.But if directly will Centrifuge tube carries out liquid nitrogen cryopreservation, and the connection between the lid and body of common centrifuge tube is not tight, and liquid nitrogen may be frozen When enter body, so as to cause take out centrifuge tube when due to liquid nitrogen Quick-gasifying cause lid spray open, to test people There is larger potential risk in member.Different lids will be also equipped with to centrifuge tube and cryopreservation tube simultaneously, it is very inconvenient.

Utility model content

For the above-mentioned state of the art, this utility model devises a kind of frozen dual-purpose explosion stack of centrifugation, while lid is centrifuged Unite two into one with cryopreservation tube lid.This utility model passes through the body for designing a replaceable lid, and lid unites two into one.The pipe Body possesses centrifugation and frozen function, and lid positive centrifugation lid is adopted when centrifugation, and the face is press-button type, easy to operate And small volume, centrifuge can be put in turn after covering the lid.After target substance has been collected, can be lid Change reverse side into, the face is spiral, the infiltration and ejection of liquid nitrogen can be prevented, and in the relatively thin region of lid Center one, this Even if there is a small amount of seepage in sample cryopreservation tube under the extreme cold of liquid nitrogen, if experimenter when cryopreservation tube is taken out by lid court To the direction away from experimenter, you can avoid the security risk of experimenter.

One kind of the present utility model is centrifuged frozen dual-purpose explosion stack and is made up of following part：

Frozen body 1 is centrifuged, in the mouth of pipe, has female thread 11；

Lid 2, is above provided with gas eruption mouth 33；2 front of the lid is centrifugation lid, has cover buckle 21 thereon；The pipe 2 back side of lid is frozen lid, and cryopreservation tube outer side of lid has external screw thread 31；

Preferably, support 12 is arranged at the body bottom that frozen body 1 is centrifuged, and has metering scale 13, and manage on body Body bottom is sharp bottom.

Preferably, there is rubber cushion 32 in the frozen lid.

The beneficial effects of the utility model：

One kind of the present utility model is centrifuged frozen dual-purpose explosion stack and possesses centrifugation and frozen function, and body adopts sharp bottom, easily Target substance in observation experiment, while design support being vertically placed in laboratory table with being easy to body；Lid is centrifuged simultaneously Unite two into one with cryopreservation tube lid.Centrifugation when using lid front, the lid be press-button type (having cover buckle), easy to operate and body Product is less, when sample is more, can be put into centrifuge one by one after covering the lid.After target substance has been collected, can Carry out frozen directly to change lid into the back side and frozen body will be centrifuged screws, the reverse side of lid is spiral, and lid is embedded in Rubber cushion, can prevent the infiltration and ejection of liquid nitrogen, and at the relatively thin region of lid Center one (gas eruption mouth), accordingly even when There is a small amount of seepage in cryopreservation tube under the extreme cold of liquid nitrogen, as long as lid is directed away from by experimenter when cryopreservation tube is taken out The direction of experimenter, you can be prevented effectively from the security risk of experimenter.To can be managed when centrifugation cryopreservation tube use is taken out again Lid changes front into carries out repetitive operation, convenient and swift.

Specific embodiment

It is centrifuged in frozen body 1 and is put into sample, the positive cover buckle 21 of lid is buckled, centrifugally operated is carried out；Collecting After complete target substance, cover buckle 21 is removed, the lid back side (frozen lid) is tightened onto into the female thread of body by screw thread 31 On 11, freeze in being put into liquid nitrogen；Lid is directed away from when taking out cryopreservation tube the direction of experimenter, frozen lid of outwarding winding is taken out Sample.The positive cover buckle 21 of lid is buckled and carries out new sample operation again.
