Abstract

The utility model discloses a kind of nitrogen to blow splashproof speed blowing apparatus, including nitrogen blowpipe (1) and culture bottle (3), it further includes bottle stopper (2) and exhaust pipe (5) that the nitrogen, which blows splashproof speed blowing apparatus, bottle stopper (2) size is matched with culture bottle (3) bottleneck size, two parallel surfaces of bottle stopper (2) are opened to have two through hole, hole size is matched with nitrogen blowpipe (1) and exhaust pipe (5), and nitrogen blowpipe (1) and exhaust pipe (5) are separately mounted in the two through hole on bottle stopper (2).Overlong time is blown to solve the problems, such as that nitrogen blows sample splashing and nitrogen in experimentation in the prior art.

Description

A kind of nitrogen blows splashproof speed blowing apparatus

Technical field

The utility model relates to microorganism fields more particularly to a kind of nitrogen to blow splashproof speed blowing apparatus.

Background technique

In microorganism purification or during culture experiment, it is often necessary to promote the microorganism concn in culture bottle, this when Time needs to use nitrogen evaporator, and principle is the liquid blown in culture bottle using the nitrogen of high-purity, makes liquid evaporation, to improve The concentration of microorganism, but nitrogen evaporator used in the prior art is to culture bottle when blowing, since culture bottle bottleneck is open, such as Fruit air pressure is excessive, which to be easy to cause sample easily to splash, influences sample amounts, but air pressure it is too small but can exist nitrogen blow overlong time influence it is real The problem of testing progress.

Summary of the invention

Technical problem to be solved by the utility model is: providing a kind of nitrogen blows splashproof speed blowing apparatus, it can be ensured that nitrogen is blown over Will not splash in journey, and nitrogen can also be reduced and blow the time, with solve in the prior art eliminate experimentation in sample splash and Nitrogen blows time long problem.

The technical solution of the utility model is: a kind of nitrogen blows splashproof speed blowing apparatus, including nitrogen blowpipe and culture bottle, the training It supports bottle bottleneck to match with bottle stopper size, two parallel surfaces of bottle stopper open to have two through hole, hole size and nitrogen blowpipe and exhaust pipe Matching, nitrogen blowpipe and exhaust pipe are separately mounted in the two through hole on bottle stopper.

The nitrogen blowpipe outlet is fixedly linked with a dispensing device, and dispensing device gas outlet is and 2 or more air inlet phases Logical gas-distributing pipe.

The bottle stopper material is rubber.

The dispensing device material is glass.

The beneficial effects of the utility model are:

Compared with prior art, the utility model avoids liquid when nitrogen is blown in culture bottle by increasing bottle stopper in bottleneck The problem of body splashes, while the utility model increases contact of the nitrogen with liquid by increasing dispensing device in nitrogen blowpipe mouth Area promotes liquid evaporation, has shortened nitrogen and has blown the time.

Bottle stopper uses rubber material, first is that fasten bottle stopper installation more, second is that air-tightness is more preferable, and liquidproof spluttering.

Dispensing device uses glass material, is more convenient for cleaning up.

Detailed description of the invention

Fig. 1 is the main view of the utility model.

In figure: 1 nitrogen blowpipe, 2 bottle stoppers, 3 culture bottles, 4 dispensing devices, 5 exhaust pipes, 7 air inlets, 8 gas outlets.

Specific embodiment

With reference to the accompanying drawing and utility model is described further in specific embodiment:

It is the preferred embodiments of the present invention with reference to Fig. 1, a kind of nitrogen blows splashproof speed blowing apparatus, including nitrogen blowpipe 1 and training Bottle 3 is supported, 3 bottleneck of culture bottle matches with 2 size of bottle stopper, and bottle stopper can be put into 3 bottleneck of culture bottle without dropping in bottle with 2, bottle Filling in 2 materials is rubber, and two parallel surfaces of bottle stopper 2 open to have two through hole, and hole size is matched with nitrogen blowpipe 1 and exhaust pipe 5, nitrogen Blowpipe 1 and exhaust pipe 5 are separately mounted in the two through hole on bottle stopper 2.

As soon as the outlet of nitrogen blowpipe 1 is linked together with dispensing device 4 by gum cover, it is smelted at the beginning of can also manufacturing Together, 4 material of dispensing device is glass, and 4 gas outlet 8 of dispensing device is the gas-distributing pipe communicated with air inlet 7.Outlet when use In the liquid that 8 insertion of mouth is blown to nitrogen, due to there is the presence of dispensing device 4, the nitrogen that the conveying of nitrogen blowpipe 1 comes is assigned to multiple small Gas-distributing pipe, more gas outlets 8 make the contact area between nitrogen and liquid bigger, to promote liquid evaporation, play Accelerate the effect that nitrogen blows speed.

It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard To belong to the protection scope of the utility model.
