Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Of course, the described embodiments are only some of the embodiments of the present invention, and not all of them.
Referring to fig. 1 and 2, in an embodiment of the present invention, an improved dissolved oxygen bottle includes a dissolved oxygen bottle body 1, a sealing plug 2, a water sealing cover 3 and a sampling plug 4; the inner wall of the dissolved oxygen bottle opening 11 is a bottle opening frosted layer 12 and is matched with a sealing plug 2, the dissolved oxygen bottle opening 11 is connected with a conical water sealing opening 13, the conical water sealing opening 13 is provided with a water distribution sealing cover 3, volatilization of moisture can be effectively prevented when the dissolved oxygen bottle is placed and cultured, the conical water sealing opening 13 is connected with a cylindrical opening 14 and is matched with a sampling plug 4, two holes are formed in the sampling plug 4, one hole is a sampling opening 41 and is connected with a siphon 42, the other hole is an air outlet 43, a closing plug 44 is arranged, sampling is convenient, and liquid level and air contact are reduced.
The lower part of the conical water seal 13 is conical, the height of the cone is 4cm, the circumferential length of the lowermost outer edge of the cone is 11cm, the circumferential length of the uppermost outer edge of the cone is 18cm, and the height of the upper connecting column-shaped opening is 1 cm.
The tapered water seal 13 is provided with a water seal cover 3, and the circumferential length of the outer edge of the water seal cover 3 is 17 cm.
A hole on the sampling plug 4 is connected with a siphon tube 42, the siphon tube 42 is made of glass, and the connection mode is seamless connection.
The air outlet 43 is provided with a closing plug 44, and the closing plug 44 is made of silica gel.
The utility model discloses a theory of operation is: during sampling, the sampling plug 4 is plugged into the cylindrical port 14, the siphon 42 is used for sampling, the air outlet 43 is opened, when sampling is finished and a small amount of overflow occurs, the air outlet 43 is closed by the closing plug 44, and during measurement, the sampling plug 4 is taken down and plugged into the sealing plug 2 immediately. If the measurement is needed after the culture, water is added into the conical water seal port 13 for water seal, and a water seal cover 3 is covered after the water seal to prevent the water sample from volatilizing.
