8-cell changer
11 8-cell changer
D This cell changer is an automatic sample changing system. The driving unit with
stepper motor is controlled by WinASPECT
®
software.
The cell changer has eight cell positions for holding 10-mm pathlength cells of the
following outer dimensions 12.5 x 12.5 x 45 (L x W x H in mm).
The stepper motor drive of the driving unit conveys the cell holder within approx. one
second to the next position. Together with a reflection coupler that defines the initial point
of the motion range, the stepper motor drive provides exactly reproducible alignment of
the cells to the sample beam.
The 8-cell changer is optionally available with temperature control (via an external ther-
mostat) and/or magnetic stirrer. Magnetic stirrer and thermostat connectors must be
factory-fitted and cannot be retrofitted.
In addition, a Peltier temperature-controlled 8-cell changer is available (→ Section
"Peltier temperature-controlled 8-cell changer”, p. 79).
