Replacing the Scrubbing Media:
- If you have a heated version, unplug the device and remove the heater blanket
- Unscrew the thumbscrew on the bottom of the housing
- Rotate the yoke which holds the housing together
- Remove the old media and dispose of properly.
- Rinse the housing with soapy water to clean
- Fill the housing with 150cc of part A material (Ceramic burl saddles)
- Fill the housing with 50cc of part B material (White pellets)
- Replace housing on top manifold
- Turn housing gently to allow o-ring on center tube and shell tube to seat properly
- Replace the yoke and tighten thumbscrew finger tight. Do not over-tighten! Over tightening will cause splintering of the plastic shell.

Selectivity
Nafion is not only highly resistant to chemical attack, it also exhibits highly selective absorption and transfer of compounds. Most substances are retained quantitatively. Although they do not attack or damage the Nafion tubing, some polar organic substances are absorbed and consequently lost. Ammonia and amines are also absorbed and lost to some degree. For retention information on specific chemicals, use the following pull down menu.
