Stainless-Steel MP-845 (MP-845S)
The MP-845 manipulator is also available in
stainless steel. The standard version of the
MP-845 has virtually no drift in its motor and
bearing assemblies. The last remaining
hurdle is that of thermal drift caused by the
expansion and contraction of the aluminum
body of the manipulator. By utilizing a
stainless steel with very low coefficient of
expansion, the MP-845S is simply the lowest
drift manipulator available on the market.
The added mass of the stainless-steel body
has the additional benefit of dampening out
vibration, giving the stainless MP-845S the
silkiest movement of any manipulator.
Because low expansion stainless steels do
have some ferric content, the stainless MP-
845S is PVD coated in titanium nitride,
giving it its distinctive gold color. This
coating will ensure that the stainless trio will
resist corrosion caused by exposure to salt
solutions in a lab environment.
