Abstract

The utility model provides a bacteria preserving tube and belongs to the technical field of a microorganism preserving device. An inoculating loop which is arranged in a tube body is fixed in a tube cover of the bacteria preserving tube provided by the utility model. When preserved bacteria is taken out for inoculation, the inoculating loop in the bacteria preserving tube is directly used for performing streak inoculation without other inoculating loops and sterilization treatment for the inoculating loop, so that time and labor are saved, and the possibility of polluting the bacteria is greatly reduced; a fungiform bulge is arranged at the top of the tube cover, so that the bacteria preserving tube can be conveniently taken out of a preserving box.

Description

Strain preservative tube

Technical field

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

Background technology

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

In practice, usually need the bacterium of these cryopreservation to inoculate activation, to carry out the lower step construction work in genetically engineered, or the bacterial classification that very low temperature is preserved is inoculated activation and amplifies and produce.When inoculation operation, 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 it is larger mutually to intersect the probability of microbiological contamination.

In addition, strain preservative tube is to be all generally placed in conserving case, then puts into refrigerator and preserves, for saving space, preserve the arrangement of pipe in conserving case 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 addressing the above problem, the utility model provides a kind of strain preservative tube, adopts following technical scheme:

A strain preservative tube, 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 mushroom projection; The bottom of described body is tip taper shape down; Conical lower section at described body arranges conduit saddle outward.

Preferably, described pipe covers with body as being threaded.

Preferably, the outer anti-slip veins that arranges of described pipe lid.

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 to the transfering loop extending 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.

4. bacterial classification, for conical, is taken out in the bottom of the preservation pipe body that the utility model provides when facilitating bacterial classification amount seldom.

5. 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.

6. the preservation pipe that the utility model provides, top at pipe lid arranges mushroom projection, when preserving installing after bacterium liquid in pipe, by preserving pipe, put into conserving case (as the conserving case of 96 grids), in the time will taking out this preservation pipe, can clamp mushroom projection with instruments such as hand or tweezers, just can pick and place easily and preserve pipe; Due to protruding setting, can avoid when picking and placeing preservation pipe with hand, the temperature of hand heats to bacterial classification, thus the situation that causes bacterial classification decline to be accelerated occurs.

Accompanying drawing explanation

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

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, 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 mushroom protruding 3; The bottom of described body 2 is tip taper shape down; Conical lower section at described body 2 arranges conduit saddle 5 outward.

Preferably, described pipe lid 1 with body 2 for being threaded; Described pipe covers the 1 outer anti-slip veins that arranges.
