Abstract

The utility model provides an easily recognized strain preserving tube, which belongs to the technical field of microorganism preserving devices. A tube cap of the preserving tube provided by the utility model is internally and fixedly provided with an inoculating loop arranged in a tube body. When preserved strains are taken out for inoculating, the inoculating loop in the preserving tube is directly used for carrying out streak inoculation without the use of other inoculating loops, sterilization treatment needs not to be carried out on the inoculating loop, so that time and labor are saved, and the possibility that strains are contaminated is greatly reduced; the top of the tube cap of the preserving tube is provided with a frosting surface, so that marking pens or labels can be used for conveniently marking the strains, and when the preserving tubes are compactly arranged in a preserving box, the strains needing to be taken out can also be conveniently recognized.

Description

Strain preservative tube easy to identify

Technical field

The utility model belongs to microorganism save set technical field, particularly relates to a kind of strain preservative tube easy to identify.

Background technology

In genetically engineered, the bacterial classification building need to be carried out to even very low temperature (80 ℃) preservation of low temperature; Owing to building cycle of bacterial classification of a desired result longer, usually also need the bacterium in some building processs to carry out cryopreservation.In practice, usually need the bacterium of these cryopreservation to inoculate activation or inoculation amplification production, when inoculation, usually adopt transfering loop to inoculate, if transfering loop sterilizing is insufficient, can cause precious bacterial classification contaminated, this will cause very large loss.Or, in order to make transfering loop sterilizing abundant, usually need the extra operating time, if inoculate different preservation bacterium simultaneously, consuming time more, and microbiological contamination probability is larger.

In addition, strain preservative tube is to be all generally placed in conserving case, then puts into refrigerator and preserves.Because the profile of preservation pipe is identical, when preparing to take out the specific preservation pipe in conserving case, be difficult to identify with the feature of preserving on pipe pipe shaft by preserving the profile of pipe.

Summary of the invention

For addressing the above problem, the utility model provides a kind of strain preservative tube easy to identify, adopts following technical scheme:

A strain preservative tube easy to identify, comprises pipe lid and body, it is characterized in that being fixed with in described pipe lid to the transfering loop extending in body; The part that described transfering loop stretches into body is spirrillum; The top of described pipe lid arranges frosting; The bottom of described body is tip taper shape down; Conical lower section at described body arranges conduit saddle outward.

Further, described pipe covers with body as being threaded; Described pipe lid arranges wear ring with the junction of body, the outer anti-slip veins that arranges of described pipe lid.

Further, described body arranges scale marks outward.

Beneficial effect of the present invention is as follows:

1. in the pipe lid of the preservation pipe that the utility model provides, be fixed with the transfering loop being placed in body, when the bacterial classification of preserving is taken out to inoculation, directly with the transfering loop of preserving in pipe, carry out streak inoculation, without other transfering loops, without transfering loop is carried out to sterilising treatment, time and labour saving, reduces the contaminated possibility of bacterial classification greatly.

2. the transfering loop of the preservation pipe that the utility model provides is that a kind of top is that ellipticity, rest part are spiral helicine transfering loop, is convenient to inoculation operation; When bacterial classification carries out low temperature even very low temperature (80 ℃) is preserved, bacterial classification is frozen into solid-state, during inoculation, turns on pipe lid and drives the transfering loop of fixed thereon to be rotated, and can take out with comparalive ease the pipe lid with transfering loop.

3. outside the preservation pipe pipe lid that the utility model provides, anti-slip veins is set, is convenient to turn on pipe lid; Pipe lid arranges wear ring with the junction of body, its sealing function, avoid preserving bacterium be frozen into solid-state before or omit out during freeze thawing, also avoid miscellaneous bacteria to enter in preservation pipe, pollute.

4. the pipe tops of the preservation pipe that the utility model provides arranges frosting, is convenient to marking pen or label bacterial classification is carried out to mark, when preservation pipe is closely emitted in conserving case, also can identify easily the bacterial classification that needs taking-up.

5. bacterial classification, for conical, also can be taken out when facilitating bacterial classification amount seldom in the bottom of the preservation pipe body that the utility model provides.

6. at the bottom of the conical tube of the preservation pipe that the utility model provides, be circumscribed with conduit saddle, when preserving pipe even very low temperature (80 ℃) take out from low temperature, staff can clamp pipe tops and conduit saddle with thumb and forefinger and carry out the transfer of bacterial classification, avoid the temperature of hand to heat to bacterial classification, accelerate the decline of bacterial classification; Conduit saddle is more conducive to preserve the plane placement of pipe.

7. the body of the preservation pipe that the utility model provides arranges scale marks outward, conveniently the bacterial classification amount of preserving in pipe is determined.

Accompanying drawing explanation

Fig. 1 represents structural representation of the present utility model; Wherein, 1 represents pipe lid; 2 represent body; 3 represent frosting; 4 represent transfering loop; 5 represent conduit saddle; 6 represent scale marks.

Embodiment

Below in conjunction with embodiment, further set forth the utility model, but be not used in restriction scope of the present utility model.

As shown in Figure 1, a kind of strain preservative tube easy to identify, comprises that pipe cover 1 and body 2, it is characterized in that described pipe covers in 1 to be fixed with to the transfering loop 4 of body 2 interior extensions; The part that described transfering loop 4 stretches into body 2 is spirrillum; The top of described pipe lid arranges frosting 3; The bottom of described body 2 is tip taper shape down; Conical lower section at described body 2 arranges conduit saddle 5 outward.

Further, described pipe lid 1 with body 2 for being threaded; Described pipe lid 1 arranges wear ring with the junction of body 2, and described pipe covers the 1 outer anti-slip veins that arranges.

Further, the outer scale marks 6 that arranges of described body 2.

Claims
