Decontaminate the sample block
Perform this procedure to eliminate fluorescent contaminants from the instrument sample block.
Contamination is generally evident in failed background calibrations where one or more wells
consistently exhibit abnormally high signals.
CAUTION!
PHYSICAL INJURY HAZARD
. Do not remove the instrument cover. There are no
components inside the instrument that you can safely service yourself. If you suspect a problem,
contact Support.
CAUTION!
PHYSICAL INJURY HAZARD.
During instrument operation, the sample block
temperature can reach 100°C. Allow it to cool to room temperature before handling.
CAUTION!
Before using a cleaning or decontamination method other than those recommended by
Thermo Fisher Scientific, confirm with Thermo Fisher Scientific that the proposed method will not
damage the equipment.
