Aseptic room, also known as inoculation room, is a special laboratory for systematic inoculation, purification of bacteria and other aseptic operations. In the microbial work, the inoculation and transplantation of bacteria is a main operation. The characteristic of this operation is to ensure the purity of bacteria and prevent the pollution of miscellaneous bacteria. Therefore, the decoration of aseptic room is very important. The following is to introduce the aseptic room decoration design specifications.
Aseptic room should be set up according to the principle of economy and science. The basic requirements are as follows:
(1) There should be two sterile rooms inside and outside. The inside is sterile room and the outside is buffer room. The room volume should not be too large for air sterilization. The area of the inner room is 2 × 2.5 = 5m2, the area of the outer room is 1 × 2 = 2M2, and the height is less than 2.5m. There should be ceiling.
(2) The inner room should be equipped with sliding door to reduce the fluctuation of air, and the door should be set far away from the workbench; the outer room should also be equipped with sliding door, which should be set far away from the inner room.
(3) In order to reduce the number of people passing in and out of the wall, a partition should be made between the inside and outside windows. The small window is 60cm in width, 40cm in height and 30cm in thickness, and the inside and outside are hung with opposite sashes.
(4) The volume of aseptic room is small and tight. After using for a period of time, the indoor temperature is very high, so ventilation window should be set. The ventilation window should be set on the ceiling at the entrance of the inner room (i.e. the position far away from the worktable). It is suggested that it should be a double-layer structure, the outer layer should be a shutter, and the inner layer can be a plate type window sash. The ventilation window can be opened after use and before sterilization to circulate air. If possible, a constant temperature and humidity machine can be installed.
