4.5 Recommendations
for Sterilizing Liquids
Important: Please read the following paragraphs before sterilizing
any liquids in your sterilizer. It is inappropriate for a healthcare facility
to sterilize liquids for direct patient contact.
Borosilicate glass is required because it is a superior glass capable
of resisting thermal shock. If glass not as thermally resistant is used,
a greater potential for bursting exists.
Vented closures are required because, by design, they release
internal pressure build-up by automatically venting the containers,
whereas pressure in unvented containers remains until the contents
have cooled. Examples of vented closures are shown in Figure 4-1.
When loading, place small containers in a separate basket to
minimize sliding. Always use side rails on the loading car to prevent
containers or baskets from falling off.
WARNING – EXPLOSION
HAZARD: This sterilizer is not
designed to process
flammable compounds.
WARNING – PERSONAL
INJURY HAZARD: Avoid
personal injury from bursting
bottles. Liquid sterilization
cycle must only be used for
liquids in borosilicate (Pyrex)
flasks with vented closures.
WARNING: It is
inappropriate for a
healthcare facility to
sterilize liquids for direct
patient contact.
WARNING – BURN
HAZARD: When sterilizing
liquids, you must observe
the following procedures:
• Use Liquid cycle only.
• Use only vented closures.
• Use only Type I
borosilicate glass bottles.
• Do not allow hot bottle to
be jolted.
• Steam may be released
from the chamber when
door is opened. Step back
from the sterilizer each
time the door is opened to
minimize contact with
steam vapor.
CAUTION–POSSIBLE
EQUIPMENT DAMAGE
HAZARD: Sterilization of
chloride-containing
solutions (e.g., saline) can
cause chamber corrosion
and is not recommended
by the manufacturer. If,
however, chloride-
containing solutions must
be processed, clean the
chamber after each use.
