The Marathon Series is made of materials that are designed to resist
attack from most laboratory chemicals. A variety of materials,
including aluminum and polypropylene, comprise the rotors and
accessories. The Chemical Resistance table shows the suitability of
each material, with different classes of reagents.
Note: Chapter 5 describes how to clean and remove corrosion from the
chamber, rotors, and accessories. Follow the instructions, and clean
spills promptly, to minimize the effect of corrosive chemicals and
avoid expensive repairs.
