1.2 Cleaning
The FLM300 should be cleaned on a regular basis.
Performance problems are often the result of dirt and
residue that build up in the cuvette chamber.
Cuvette Holder Cleaners are used to clean residue and
small spills from the cuvette chamber and the separate
cuvette heating block. The directions are as follows:
1. Moisten the cleaner, insert it into the chamber and
leave it for several minutes.
2. Gently pull the cleaner out and discard. (Cuvette
Holder Cleaners are not reusable).
If the Cuvette Holder Cleaners cannot suciently absorb
a spill, the FLM300 must be disassembled and
thoroughly cleaned following the procedure below:
Tools needed:
