Description
Technical field
The utility model relates to incubator, refers to especially two-door device and deaerating type of cycles for the incubator handle hole.
Background technology
Provide specific growing environment condition to manipulation requires such as the separation of anerobe, cultivations in the experimentation of microorganism, anerobe is unfavorable for growing in aerobic environment, cultivate anerobe, must create the environment of a relative anaerobic.Usually we adopt and in incubator, anaerobe are cultivated, and make the interior oxygen concentration of incubator lower than 5%.Based on the needs of laboratory culture anaerobe, various automatization anaerobic device equipment are arranged in the market, but these equipment are complicated, cost is high, and is bulky.And the generation of the oxygen-free environment of these equipment normally first vacuumizes whole incubator, then fills anaerobic gas, and such process repeats more than 3 times repeatedly, and so operation can be wasted anaerobic gas, causes running cost high.When operating simultaneously, must be with hermetic rubber gloves in needs are stretched out one's hand the anaerobic system, affect operating handle.
The utility model content
A kind of two-door device for the incubator handle hole that the utility model proposes, and the deaerating type of cycles that utilizes this two-door device.It can save anaerobic gas, reduces and cultivates cost; Need not to affect the rubber gloves of operating handle, improved the fineness of operation.
The technical solution of the utility model is achieved in that
A kind of two-door device, it is installed on the handle hole place of incubator, it comprises the inside door that is connected with the incubator inner wall sealing, and the external door that is connected with the incubator outer wall and arranges face-to-face with described inside door, described external door is sealedly connected with movable oversleeve, and the other end of described movable oversleeve is connected with naked hand oversleeve.
Correspondingly, a kind of deaerating type of cycles that utilizes described two-door device, comprise the culturing room, source of the gas and the vacuum pump that are surrounded by incubator, described source of the gas is connected with vacuum pump pipeline with culturing room respectively by three-way solenoid valve, described culturing room is connected with the oxygen concentration table, described vacuum pump pipeline is connected with two-door device, and described two-door device is connected with the source of the gas pipeline.
The employing the beneficial effects of the utility model are: after the oxygen concentration in incubator reaches prescribed value, operate in needs are stretched out one's hand incubator, at this moment only need to carry out deoxygenation to the seal cavity between inside door and external door.Because the sealing space is little, only need take out vacuum one time, then be filled with anaerobic gas and get final product.Then can open inside door, hand just can directly reach and carry out hand operation in incubator, affects the problem of operating handle with regard to avoiding owing to wearing gloves like this.
Oxygen concentration in incubator can be controlled by deaerating type of cycles, and source of the gas provides anaerobic gas, utilizes the oxygen concentration table to detect oxygen concentration in culturing room, when the oxygen concentration tabular value surpasses prescribed value, just is filled with anaerobic gas toward case in, while Exhaust Gas outside case.So repeated multiple times, until the oxygen concentration of culturing room reaches prescribed value, such deaerating type of cycles can be saved 2/3rds anaerobic gas than existing general scheme.On the other hand, when hand need to carry out hand operation, hand first stretched in two-door device, vacuumized by vacuum pump, then was filled with anaerobic gas, thus, with regard to can not re-starting the deoxygenation operation to culturing room because hand enters incubator, had saved anaerobic gas.From above-mentioned two aspects, this deaerating type of cycles has been saved the anaerobic gas of cultivating use, has reached and has reduced the purpose of cultivating cost.
