TITEMS is a complex chemical formulation
providing assurance that the three major parameters of the
sterilization process have been met. Thus steam quality,
temperature and time are monitored to the point that the
confirmation with biological spores will be compatible with
the colour change from white to black. IE, The end point of
the colour change is aligned to the thermal death time of B
Stearothermophilus with an added safety margin.
TITEMS should not be regarded
as a sterilization indicator, but rather as an accurate
monitor of the functions required by the sterilizer. The
purity and quality of the formulation is primarily the
reason for its accuracy, but the method of production
involving paper of neutral pH, the application of the
chemical by silk screen technology all provide for high
reliability. The amount of chemical applied to the paper
substrate is critical for optimal reaction and this also
sets TITEMS apart from other products.
TITEMS may be used in all steam sterilizers
operating at temperatures from 121°C to 142°C. The relative
time period for all processed is controlled by means of
barrier resins: eg. exposure at 121°C for 15 minutes; at
134°C for three minutes will allow the complete colour
change from white to black.
