The purpose of the cleaning procedure is to remove grease, dirt, and other soluble
substances that can absorb or release water during verification, calibration, or sample
testing. For the laser and IR sensor to perform well, they must be clean and free from
contaminants.
The instrument should be cleaned if visual inspection indicates the chamber is dirty or as
part of the verification process (Section4.1).
4.2.1 CLEANING KIT
The AQUALAB comes with an AQUALAB Cleaning Kit that contains enough cleaning supplies
to clean the instrument for about 1 year. The following supplies are included:
• Spatula (a thin plastic rod)
• Deionized water for cleaning
• Cleaning Solution
• KIMWIPES
®
tissues
• Activated charcoal
NOTE: Wash hands with soap and water, and wear clean gloves before starting the cleaning procedure. This prevents
oils from contaminating the cleaning materials, the sample chamber, and the sensors.
