- chemical control
3 physical control methods?
the use of a filter to separate particulate matter from liquids or gases
commonly used on pharmaceuticals

the most common method of sterilization
what are the 2 types of heat?
this type of heat sterilization is done by either boiling or steam under pressure
kills microbes by coagulating critical cellular proteins
type of heat sterilization that is difficult to control
longer sterilization pd, kills microbes by protein oxidation
type of moist heat
only sanitizes at 60C or 140F & higher
sanitizin can be increased with scrubbing and detergent
ex: auto dishwashers/ clothes washers
type of moist heat (2)
rarely used because spores and viruses are not killed @ this temp for long pds of time
