Laboratory
General Sterility and Cleanliness
The sterility and cleanliness of the laboratory is
necessary to ensure the integrity of samples and analytical procedures.
- Traffic through the laboratory is restricted to those
doing work in the laboratory, especially when analytical work is being done.
- The countertops are wiped down with surface
disinfectants, such as Conflikt (Decon Labs, Inc., King of Prussia, PA) or
70 percent ethanol, before and after use.
- Antimicrobial soap is available at various laboratory
sinks to facilitate hand washing before and after laboratory work.
Clean and sterile glassware that is free of detergent residue
is crucial to ensure valid results in microbiology.
- Dirty dishes are placed on a moveable laboratory cart
after use and are not to be stored on countertops. Dishes are washed in a
dishwasher or by hand with hot water and laboratory-grade phosphate-free
detergent, such as Liqui-Nox (Alconox, Inc., White Plains, NY). Dishes are
rinsed with tap water and then 3 rinses with deionized water.
