Abstract

The invention provides a kind of strain preservative tube, belong to microorganism preservation device technical field.The pipe lid internal fixtion of preservation pipe provided by the invention has the transfering loop be placed in body, when the bacterial classification that will preserve takes out inoculation, transfering loop in direct preservation pipe carries out streak inoculation, without the need to other transfering loops, without the need to carrying out sterilising treatment to transfering loop, time and labour saving, reduces the contaminated possibility of bacterial classification greatly; The top of pipe lid arranges mushroom projection, can pick and place easily and preserve pipe from conserving case.

Description

A kind of strain preservative tube

Technical field

The invention belongs to microorganism preservation device technical field, particularly relate to a kind of strain preservative tube.

Background technology

In genetically engineered, need the bacterial classification built to be carried out low temperature even very low temperature (-80 DEG C) preservation; Because the cycle building the bacterial classification that can produce a desired effect is longer, usually also need the bacterium in some building processs to be carried out low temperature (such as-20 DEG C) and preserve.

In practice, usually need the bacterium of these cryopreservation to be carried out inoculation activation, to carry out the lower step construction work in genetically engineered, or the bacterial classification of Excised Embryos is carried out inoculation activation and amplify producing.When inoculation operates, usually adopt transfering loop to inoculate, if transfering loop sterilizing is insufficient, precious bacterial classification can be caused contaminated, and this will cause very large loss.Or, in order to make transfering loop sterilizing abundant, usually need the extra operating time, if the preservation bacterium that Simultaneous vaccination is different, then consuming time more, and the probability of intersection microbiological contamination is larger mutually.

In addition, strain preservative tube is all generally be placed in conserving case, then puts into refrigerator and preserves, for saving space, preserve the arrangement of pipe in conserving case relatively tightr, again due to freezing, operator are usually difficult to the bacterial classification of preservation to take out from conserving case.

Summary of the invention

For solving the problem, the invention provides a kind of strain preservative tube, adopting following technical scheme:

A kind of strain preservative tube, comprises pipe lid and body, it is characterized in that the transfering loop extended in the oriented body of described pipe lid internal fixtion; The part that described transfering loop stretches into body is spirrillum; The top of described pipe lid arranges mushroom projection; The bottom of described body is provided with the concave inward structure to tube cavity depression.

Preferably, described pipe lid and body are for being threaded; The junction of described pipe lid and body arranges wear ring.

Preferably, outside described pipe lid, anti-slip veins is set.

Beneficial effect of the present invention is as follows:

1. the interior transfering loop extended of the oriented body of pipe lid internal fixtion of preservation pipe provided by the invention, when the bacterial classification that will preserve takes out inoculation, transfering loop in direct preservation pipe carries out streak inoculation, without the need to other transfering loops, without the need to carrying out sterilising treatment to transfering loop, time and labour saving, reduces the contaminated possibility of bacterial classification greatly.

2. the transfering loop of preservation pipe provided by the invention is a kind of top is ellipticity, rest part is spiral helicine transfering loop, is convenient to inoculation operation; When bacterial classification carry out low temperature even very low temperature (-80 DEG C) preserve time, bacterial classification is frozen into solid-state, during inoculation, turns on pipe lid and then drives the transfering loop of fixed thereon to rotate, can take out the pipe lid with transfering loop with comparalive ease.

3. outside preservation pipe pipe lid provided by the invention, anti-slip veins is set, is convenient to turn on pipe lid.

4. preservation pipe provided by the invention, at the top of pipe lid, mushroom projection is set, when preserve in pipe install bacterium liquid after, preservation pipe is put into conserving case (conserving cases as 96 grids), in time will taking out this and preserve pipe, with the instrument such as hand or tweezers, mushroom projection can be clamped, just can pick and place easily and preserve pipe; Due to the setting of projection, can avoid when picking and placeing preservation pipe with hand, the temperature of hand heats to bacterial classification, thus the situation causing bacterial classification decline to be accelerated occurs.

5. the bottom of preservation pipe body provided by the invention arranges concave inward structure, when from low temperature, even very low temperature (-80 DEG C) takes out preservation pipe, staff can carry out the transfer of bacterial classification with the edge section that thumb and forefinger clamp pipe tops and concave inward structure, avoid the temperature of hand to heat to bacterial classification, accelerate the decline of bacterial classification; In addition, the plane that concave inward structure is more conducive to preserve pipe is placed, and can also protect bottle not by damage, improve the security of culture presevation.

6. outside preservation pipe pipe lid provided by the invention, anti-slip veins is set, is convenient to turn on pipe lid; The junction of pipe lid and body arranges wear ring, its sealing function, avoid preserve bacterium be frozen into solid-state before or freeze thawing time omit out, also avoid miscellaneous bacteria enter preservation pipe in, pollute.
