22.214.171.124.1. Criteria for using saturated salts to regulate incubator relative humidity for maintaining adult workers in the laboratory
The following criteria are discussed by Winston and Bates (1960). Expected relative humidity values produced using saturated salt solutions may vary when experimental conditions do not permit all criteria to be met.
- Container (i.e. incubator) must be a closed system.
- A fan to distribute air should be provided when incubator volume is >1 litre.
- Surface area of the solution should be as large as possible.
Reagent grade chemicals should
be used to allow for reproducibility
