4.4 Chemical Resistance Table
The centrifuge, rotors and accessories are comprised of made of materials that are designed to resist attack from most
laboratory chemicals. For your convenience, the chemical resistance table below shows the suitability of various materials
with different classes of reagents.
NOTE: Refer to the cleaning section for information on cleaning and removing corrosion from various parts. Clean spills
promptly to minimize the effect of corrosive chemicals and avoid expensive repairs.
*For Oxidizing Acids, see "Oxidizing Agents, strong”.
