Design and Function
Conveyor Chain Motor
The SampleXpress uses an electric DC motor to drive the sample conveyor chain in the
cassette. To minimize the influence on the NMR measurement, this motor is mounted
with special vibration damping parts.
As an option for very strong magnetic fields, the motor can be placed outside the 5
Gauss line.
Cassette Clamp Mechanism
Figure 5.4 Clamp Closed
Figure 5.5 Clamp Open
When a cassette is moved into the Sam-
pleXpress, it is fixed by a clamping mecha-
nism. This is a special kind of gripper
adapted to a pneumatic gripper cylinder.
The gripper (Figure 5.4/1) is placed behind
a metal shield to avoid injury to personell
while the unit is operating.
