Replacing the Desiccant
The optical components of your instrument are protected by two desiccant canisters that
absorb moisture. As long as the humidity indicator on your instrument’s main cover is blue,
the desiccant canisters are not saturated and do not need to be replaced. When the desiccant
canisters become saturated, the humidity indicator turns pink or white. This means you must
replace the desiccant cartridges.
Time needed:
3 minutes or less
Tools needed:
4-in1 tool (included with your instrument)
Replacement (or regenerated) desiccant canisters (2)
NOTICE
We recommend that you maintain seal and desiccation and/or purge your
instrument at all times. Equipment damage due to failure to maintain seal and desiccation
and/or purge is not covered under the warranty. If you have questions about this
requirement, please contact us.
NOTICE
• Use only Thermo Scientific certified replacement parts. To order parts, contact us.
• Make sure nothing falls into the instrument while the desiccant cover is removed.
