INTRODUCING THE BRIGHTCHEQ INCUBATOR
The BRIGHT-CHEQ incubator is a valuable laboratory tool used for the rapid evaluation and
automatic documentation of Etigam BRIGHT-CHEQ steam biological indicators (BIs). The
incubator monitors BRIGHT-CHEQ BIs during incubation and alerts the user when growth is
detected (positive) or when the incubation period has ended without any growth detected
(negative).
The Etigam BRIGHT-CHEQ is a self-contained color-change biological indicator consisting of a
small plastic culture tube containing an inoculated paper strip and a glass ampoule of growth
medium. Upon removal from the sterilizer, the BRIGHT-CHEQ BI is activated by exing the
culture tube in the BRIGHT-CHEQ incubator’s crushing cavity to break the media ampoule
inside, allowing the growth medium to mix with the paper spore strip. If any spores have
survived the sterilization process, the bacteria will grow during incubation and cause the pH
indicator dye in the growth medium to change from purple to yellow.
The BRIGHT-CHEQ incubator continuously monitors up to ten independent BRIGHT-CHEQ
biological indicators for any color change to yellow during the incubation period. All test
results are automatically printed to the attached printer the moment they become available,
and the user is alerted to any change in test status by an audible alarm. Because the incubator
relies solely on a color change in the biological indicator itself, all test results are veriable by
the user.
The BRIGHT-CHEQ incubator features a touch-sensitive liquid crystal display (LCD) for
conguration, report customization, and monitoring the status of each incubation cell. The
user can set the current time and date, adjust the incubation time, change display and sound
settings, and enter cell-specic test information to be printed on each test report, such as
sterilizer number and BI lot number.
The BRIGHT-CHEQ incubator is calibrated to 60ºC ± 2ºC for proper incubation of BRIGHT-CHEQ
biological indicators containing spores of Geobacillus stearothermophilus. The incubator has a
small chamber for the included NIST-traceable thermometer which can be used to easily verify
that the unit is maintaining correct temperature.
