Replacing the desiccant

Follow the instructions in this section to replace the desiccant cartridges.

 
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.

Time needed: 3 minute or less

Tools needed:

  • 4-in1 tool (included with your instrument)
  • 2 replacement (or regenerated) desiccant canisters
 
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.
  1. Open the tool compartment, and use the 4-in-1 tool, with the large Phillips bit installed, to loosen the captive screw in the desiccant cover. 

Lift off the desiccant compartment cover and put it in a safe place.
