Magnet Weight Distribution—No Antivibration System
This section describes weight distribution for magnets without antivibration systems. The
weights of the magnets, including stands, are given in
.
200/54 and 300/54 magnets: The plan view of the magnet stand, illustrated in
A,
shows how the two rectangular legs contact the floor. The magnet stand has four adjustable
feet of 11.61 cm
2
(1.8 sq in.) each (total 45.16 cm
2
or 7 sq in.); therefore, the “point
loading” is relatively high. Because of the overall light weight of these magnets, however,
this is usually not a concern except in areas with a soft floor covering.
400/54 and all long-hold magnets: The stands for these magnets consist of three legs, as
shown in the plan view in
B. Since the legs are hollow, the actual surface contact
with the floor is only 167.74 cm
2
(26 sq in.) total, which creates relatively high “point
loading.” This is only a concern, however, if the floor covering is soft.
Magnet Weight Distribution—With Antivibration System
This section describes weight distribution for magnets installed with antivibration systems.
The weights of the magnets, with stands and antivibration systems, are listed in
200/54 and 300/54 magnets without the SMS autosampler: The antivibration system
consists of a square table supported by three legs. See
for leg placements and sizes.
