Wall-mounted second-order humidifying pan inside shaking incubator

Abstract

The invention discloses a wall-mounted second-order humidifying pan inside a shaking incubator. The wall-mounted second-order humidifying pan comprises an upper humidifying pan and a lower humidifying pan, wherein the two humidifying pans are arranged in an inner container of the incubator, and the upper humidifying pan is movably mounted on a hanging plate movably mounted on the side wall of the inner container of the incubator. A supporting plate is fixedly arranged at the lower end of the hanging plate, the upper humidifying pan is placed on the supporting plate and made of stainless steel, and the lower humidifying pan is fixedly mounted at the bottom of the inner container of the incubator. The wall-mounted second-order humidifying pan is simple, convenient and exquisite in structure, the bottom space of the shaking incubator is effectively used, normal shaking incubation cannot be affected, large-area natural humidifying and high-humidity requirements in the shaking process are met, unrepairable damage to an incubator body caused by solution such as copper sulfate is effectively overcome, and the cost of instrument replacement is saved.

Description

technical field [0001] The invention relates to the field of biological instruments, in particular to a wall-mounted second-stage humidification tray used in an oscillating incubator. Background technique [0002] In view of the fact that there is only one layer of built-in humidification pan under normal circumstances, and the humidification area is relatively small, mostly within 600cm 2 About, in the process of mammalian cell culture, can not provide enough humidity, natural humidification can only reach 70%, can not reach the optimum humidity of normal culture above 95%, in addition, due to the humidity, it is easy to grow other bacteria that are not required for culture , causing pollution to normal culture bacteria, so a saturated solution of copper sulfate is often added inside to provide a sterile environment, but copper sulfate is corrosive to a certain extent, and it is easy to crystallize and cause damage to the box, because the main component of stainless steel i...

[0002] In view of the fact that there is only one layer of built-in humidification pan under normal circumstances, and the humidification area is relatively small, mostly within 600cm 2 About, in the process of mammalian cell culture, can not provide enough humidity, natural humidification can only reach 70%, can not reach the optimum humidity of normal culture above 95%, in addition, due to the humidity, it is easy to grow other bacteria that are not required for culture , causing pollution to normal culture bacteria, so a saturated solution of copper sulfate is often added inside to provide a sterile environment, but copper sulfate is corrosive to a certain extent, and it is easy to crystallize and cause damage to the box, because the main component of stainless steel is iron It is easy to replace the copper in the copper sulfate, and eventually the tank will be corroded and leaked, or multiple crystal blocks will be formed in the tank in a short period of time, resulting in the failure of the entire shaking incubator.

In addition, the vibrating incubator for mammalian cell culture is more than 200,000 in China and more than 600,000 in imports, and the cost is high; in addition, since there is only one layer, only water humidification or copper sulfate is used to provide a sterile environment, and sulfuric acid is added. The copper cabinet is corroded and leaking and cannot be replaced
