How to maintain the biological safety cabinet regularly

The working principle of the biological safety cabinet is mainly to suck the air in the cabinet to the outside to keep the negative pressure in the cabinet and protect the staff through vertical airflow; the outside air is filtered by high-efficiency particulate air filter (HEPA). The air in the cabinet also needs to be filtered by HEPA filter and then discharged into the atmosphere to protect the environment.
Biosafety cabinets are widely used in medical and health, disease prevention and control, food hygiene, biopharmaceuticals, environmental monitoring and various biological laboratories. The following introduces you how to maintain the biological safety cabinet regularly.
  one. daily maintenance
1) Use 70% alcohol (other fungicides (inorganic compounds) depend on the materials used by the user) to thoroughly purify the surface, side walls, rear walls and windows of the inner working area of the safety cabinet. Biosafety cabinets are widely used in medical and health, disease prevention and control, food hygiene, biopharmaceuticals, environmental monitoring and various biological laboratories. Do not use disinfectants that contain chlorine as it may damage the stainless steel construction of the cabinet. Also clean the surface of the UV lamp and power outlet. When cleaning the inner area of the safety cabinet, the operator should not enter the safety cabinet with any other part of the body except the hands
2) Check the alarm and detect (check and test) the basic airflow
  two. weekly maintenance
1) Thoroughly clean the drain with 70% alcohol (other fungicides depend on the materials used)
2) Check the residual material at the hole of the capture paper
  three. monthly maintenance
1) Wipe the outer surface of the safety cabinet with a damp cloth, especially the front and upper parts of the safety cabinet, and clean the accumulated dust. The biological safety cabinet is used to protect the operator, laboratory environment and experimental materials from exposure to the above-mentioned operation process when handling infectious experimental materials such as primary cultures, bacterial strains and diagnostic specimens. Designed for possible infectious aerosols and splashes.
2) Check the reasonable use of all maintenance accessories.
3) Items in the above daily work
  Four. quarterly maintenance
1) Check the safety cabinet for any physical abnormalities or malfunctions. The biological safety cabinet is used to protect the operator, laboratory environment and experimental materials from exposure to the above-mentioned operation process when handling infectious experimental materials such as primary cultures, bacterial strains and diagnostic specimens. Designed for possible infectious aerosols and splashes. Check the fluorescent picture tubes to make sure they are working properly
2) MEK can be used when there are spots on the upper surface of stainless steel that are difficult to remove. After using WEK, quickly rinse the stainless steel plate with water and liquid detergent, and wipe with a polyurethane cloth or sponge. Regular cleaning of stainless steel surfaces will keep them looking smooth and beautiful.
  Fives. annual maintenance
1) Qualified certified technicians certify the performance of the safety cabinet.
2) Replace the UV lamp
3) The above-mentioned quarterly maintenance.
