Description

Laboratory is with little biological culture device

Technical Field

The utility model belongs to the microorganism culture field specifically is laboratory is with microorganism culture apparatus.

Background

Anaerobic microorganisms are widely distributed in nature, are various in types, and increasingly attract attention to the action. The key to anaerobic microorganism culture is to maintain the microorganism in an anaerobic environment during culture.

At present, anaerobic microorganism culture generally adopts an anaerobic tube, an anaerobic bottle, an anaerobic jar culture method or an anaerobic glove box. Anaerobic tubes are small in volume (no more than 30mL) and are generally suitable for culturing only a small amount of microorganisms (no more than 10 mL). Although the anaerobic tank and the anaerobic incubator can be used for anaerobic microorganism culture, the anaerobic tank and the anaerobic incubator have many defects, such as high price, large volume, incapability of keeping constant temperature, unsuitability for culturing extreme anaerobic microorganisms (such as seabed strains and deep soil strains), and few or no configuration in a common laboratory, so that the teaching requirement of the anaerobic microorganism experiment in the family cannot be met.

In the laboratory, the application of the anaerobic bottle is wider. The volume of the anaerobic bottle is variable (50mL-1000mL), and the anaerobic bottle is suitable for culturing a small amount of anaerobic microorganisms and a large amount of anaerobic microorganisms. The anaerobic bottles used in laboratories are imported and domestic, and the imported anaerobic bottles are high-temperature resistant, high-pressure resistant and not easy to explode, but are expensive and not suitable for mass use in the experiment teaching of the department. Although the price of the domestic anaerobic bottle is low, the domestic anaerobic bottle has poor high-pressure resistance and is easy to explode at high temperature, and the explosion of the anaerobic bottle damages sterilizing equipment and endangers the life safety of experimenters. In addition, the bottle mouth of the conventional anaerobic bottle is most easily damaged in the using process, once the bottle mouth of the anaerobic bottle is damaged, the whole anaerobic bottle can not be used, a new anaerobic bottle needs to be purchased, and the purchase cost of the new anaerobic bottle is high.

Therefore, how to design a culture device which can reduce the contact area of anaerobic bacteria and air and simultaneously avoid the damage of a bottle mouth is of great significance.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model aims to provide a culture device which can reduce the contact area between anaerobic bacteria and air and avoid the damage of a bottle mouth.

In order to achieve the above purpose, the technical solution of the present invention is as follows: microbial cultivation device is used in laboratory, including the wide-necked bottle, the bottleneck department of wide-necked bottle has the block, the block is including the stopper portion of connecting the bottleneck and the cap portion of contact operating personnel palm, the vertical axis department of stopper portion is hollow, and stopper portion circumference has the thread tooth, and the internal surface of cap portion has the thread groove, cap portion and stopper portion threaded connection, cap portion and stopper portion screw-thread fit.

Further, a holding table is arranged between the plug part and the cap part, the diameter of the holding table is larger than that of the cap part, and the diameter of the holding table is also larger than that of the plug part.

Further, the cap is provided with a friction groove in the circumferential direction.

Further, the wide-mouth bottle still includes the body, the radial both sides of body all have the support, the cross section of support is "L" shape, the support includes horizontal pole and montant, body and montant are connected to the horizontal pole, and the montant is towards below.

Further, the wide-mouth bottle adopts borosilicate material.

After the scheme is adopted, the following beneficial effects are realized: 1. in the use, because this device has the support that the cross section is "L" shape, the opening of support is downward, and the operating personnel of being convenient for transversely passes the support with the hand when using the wide-necked bottle and carries out portable operation, has avoided operating personnel's hand directly to grip the wide-necked bottle simultaneously.

2. When needs carry out culture medium or sampling operation to bacterial (especially anaerobe), operating personnel can operate under the state of not uncork, only need unscrew cock part and cap portion, and operating personnel can add culture medium through the hollow department of cock part, also can extract partial bacterial through the cock part simultaneously, has reduced the area of contact of wide-necked bottle with the air under this kind of operation, has avoided the anaerobe dead, has promoted the efficiency of cultivateing.

3. Because the cap part is provided with the friction groove, the friction force between the cap part and the hand of an operator is increased, and the cap part is unscrewed and then is separated from the plug part.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the wide-mouth bottle comprises a wide-mouth bottle 1, a plug part 2, a cap part 3, a thread tooth 4, a hollow part 5, a holding table 6, a bracket 7 and a friction groove 8.

The embodiment is basically as shown in the attached figures 1 and 3: microorganism culture apparatus is used in laboratory, including the wide-necked bottle 1 that adopts the borosilicate material, the bottleneck department of wide-necked bottle 1 has the block, the block is including the cap portion 3 of the stopper portion 2 and the contact operating personnel palm of connecting the bottleneck, hollow 5 in the vertical axis department of stopper portion 2, 2 circumference of stopper portion has thread tooth 4, the internal surface of cap portion 3 has the thread groove, cap portion 3 and 2 threaded connection of stopper portion, cap portion 3 and 2 screw-thread fit of stopper portion, it holds platform 6 to have to hold between stopper portion 2 and the cap portion 3, the diameter of holding platform 6 is greater than cap portion 3, the diameter of holding platform 6 also is greater than stopper portion 2.

Referring to fig. 2, the cap 3 has a friction groove 8 along the circumference, the jar 1 further includes a body, the two sides of the body in the radial direction are provided with a support 7, the cross section of the support 7 is "L" shaped, the support 7 includes a cross bar and a vertical bar, the cross bar connects the body and the vertical bar, and the vertical bar faces downward.

The specific implementation process is as follows: in the use, because this device has the support 7 that the cross section is "L" shape, the opening of support 7 is downward, transversely passes support 7 with the hand when being convenient for operating personnel uses wide-necked bottle 1 and carries out portable operation, has avoided operating personnel's hand directly to grip wide-necked bottle 1 simultaneously, has reduced the influence of human hand temperature to the bacterial.

When culture medium or sampling operation is required for strains (particularly anaerobic bacteria), an operator can operate the culture medium or sampling operation without opening the bottle, at the moment, only one hand of the operator is needed to hold the surface of the holding platform 6 to fix the wide-mouth bottle 1, then the other hand of the operator rotates the cap part 3, and because the cap part 3 is provided with the friction groove 8, the friction force between the cap part 3 and the hand of the operator is increased, and the cap part 3 is unscrewed and then is separated from the plug part 2.

After cap portion 3 and stopper portion 2 break away from the combination, because the hollow 5 of the vertical axis department of stopper portion 2, so operating personnel can add culture medium through the hollow 5 departments of stopper portion 2, also can extract partial bacterial through stopper portion 2 simultaneously, reduced the area of contact of wide-necked bottle 1 with the air under this kind of operation, avoided the anaerobism bacterial death, promoted cultivated efficiency.

When the addition or sampling is completed, the medical staff rejoins the cap 3 with the plug 2 and screws it down for the next use.
