BD Kiestra ReadA - Cleaning strategies for incubator interior

5.2.1 Dry cleaning
In order to remove dust and small particles from modules and work surfaces, use:
l
A small brush or microfiber wipe to clean sensors
l
Microfiber wipes to clean scanner windows
l
A vacuum cleaner with a HEPA filter (supplemented by a brush if necessary) for dusty areas
When using a brush, be careful not to move dirt to a clean location.
5.2.2 Wet cleaning/disinfecting
CAUTION
Never spray or pour cleaner/disinfectant on or into the module or any part of the
module. Always spray onto a microfiber wipe and then wipe the
cleaner/disinfectant onto the module component.
Do not use cleaning agent on computer screens, except when microbial
contamination on the monitor surface occurs or is suspected.
Wet cleaning is performed as follows:
1. For routine cleaning/disinfection, spray the cleaner/disinfectant onto a microfiber wipe. Use
the microfiber wipe to spread the cleaner/disinfectant over all components and surfaces to
be cleaned, especially conveyor belts, Stackers, and Destackers.
2. Thoroughly dry sensors and scanner windows with a lint-free microfiber wipe.
5.3 Cleaning strategies for incubator interior
The optimal strategy to clean the interior of the ReadA is determined by:
l
The number of plates present in the ReadA at the time cleaning is being performed
l
The availability of storage space in other ReadA modules with identical storage conditions
l
The preference to unload plates automatically or manually
The options for cleaning a ReadA are:
1. Cleaning a whole ReadA at one time. This approach can be used if a lab has sufficient
capacity of a specific atmosphere (CO
2
or O
2
) such that a ReadA can be completely
emptied for cleaning.
There are two choices for unloading a ReadA for complete cleaning:
l
Protocol A: Automatic unloading of plates; plates are automatically transferred from
the ReadA to a cleaning Stacker and eventually pushed onto a plate cart. The plates
may be stored on the plate cart or placed into a Destacker for transfer to another
available ReadA with the same atmospheric conditions for storage. A plate cart can
hold a maximum of 600 plates.
l
Protocol B: Manual unloading of plates; the door of the ReadA is opened and plates
are manually collected from the racks.
