Microplate Rotor
The Microplate Rotor is designed for centrifugation of multi-well microplates. The weight of the loaded microplates must
be equally distributed between the rotor’s two carriers. The maximum rated speed for the rotor when each of the carriers
is loaded with 320 grams (total load of 640 grams) is 3650 rpm.
CAUTION
!
Loads greater than 320 grams (weight of the microplate and sample) must have maximum speed derated (according to
the following table) to avoid rotor failure.
4.4 Chemical Resistance Table
The centrifuge, rotors and accessoires 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”.
