Microbiological laboratory decoration is different from general laboratory engineering or purification engineering. Generally, it consists of main laboratory and auxiliary function laboratory, and the design scheme is quite different from other laboratories. Microbial safety laboratory must ensure personal safety, environmental safety, waste safety and sample safety, and can operate safely for a long time. At the same time, it also provides a comfortable and good working environment for laboratory staff.
The sterile room should be set up according to the principle of economy and science. Its basic requirements are as follows:
1. The sterile room should have two rooms, one inside the sterile room and the other outside the buffer room. Room volume should not be too large to facilitate air sterilization. The interior area is 2 *2.5=5m2, the exterior area is 1 *2=2m2, and the height is below 2.5m. There should be a ceiling.
2. Sliding doors should be installed in the interior to reduce the fluctuation of air. The doors should be located farthest from the workbench. Sliding doors should also be used in the exterior doors, which should be located farthest from the interior.
3. A small window should be opened on the walls or "partitions" between the interior and the exterior so as to provide the necessary passageway for the delivery of goods inside and outside during the inoculation process, so as to reduce the number of people entering and leaving the interior and reduce the pollution level. The small window is 60 cm wide, 40 cm high and 30 cm thick, and the inside and outside windows are hung with opposite pull-out fans.
4. The sterile room is small and compact. After using for a period of time, the indoor temperature is very high. Therefore, ventilation windows should be set up. The ventilation window should be set on the ceiling at the entrance door of the inner room (that is, the farthest position from the workbench), preferably with double-deck structure, with shutters on the outer layer and suction-plate windows on the inner layer. The ventilation window can be opened after use in the inner room and before sterilization to circulate air. Conditional installation of constant temperature and humidity machine.
