Abstract

The invention provides an easily identified strain preservation tube and belongs to the technical field of microorganism preservation devices. An inoculating loop in a tube body is fixed in a tube cover of the preservation tube; when being taken out and inoculated, a preserved strain is subjected to streak inoculation by the inoculating loop directly without other inoculating loops, and the inoculating loop does not need to be sterilized, so that the time and the labor are saved and the probability of pollution to the strain is greatly reduced; a frosted surface is arranged at the top of the tube cover of the preservation tube, so that the strain can be conveniently marked by a marking pen or a label, and strains required to be taken out also can be conveniently identified when preservation tubes are closely arranged in a preservation box.

Description

Strain preservative tube easy to identify

Technical field

The invention belongs to microorganism save set technical field, particularly relate 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 invention provides a kind of strain preservative tube easy to identify, adopt 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 of preservation pipe provided by the invention lid, 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 preservation pipe provided by the invention 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. preservation pipe pipe lid provided by the invention is outer arranges anti-slip veins, 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 preservation pipe provided by the invention 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. the bottom of preservation pipe body provided by the invention is conical, when facilitating bacterial classification amount seldom, also can take out bacterial classification.

6. at the bottom of the conical tube of preservation pipe provided by the invention, 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 preservation pipe provided by the invention 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 invention; 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 present invention, but be not used in, limit the scope of the invention.

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

1. a strain preservative tube easy to identify, comprises pipe lid (1) and body (2), it is characterized in that being fixed with to the interior transfering loop (4) extending of body (2) in described pipe lid (1); 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.

2. according to the strain preservative tube described in claim 1, it is characterized in that: described pipe lid (1) with body (2) for being threaded; Described pipe lid (1) arranges wear ring with the junction of body (2); The outer anti-slip veins that arranges of described pipe lid (1).
