CS-3A
ALS Cell Stand Ver. 1.1
Faraday Cage, purging & Magnetic Stirrer in a single device
The CS-3A Cell Stand can be controlled with other apparatus directly. The cell is enclosed in a Faraday cage to reduce electrical interference.
A built-in gas control allows purging a sample. Gas line is provided to purge next sample, while analyzing the present sample separately, thus increasing productivity.
Magnetic stirrer allows for controlling the mixing of the sample for experiments requiring mass transport of electrolyte or analyte to the electrode surface. Cell top positioner with detachable cell cap allows easy removal and replacement of the cell vial as well as the electrodes for rinsing, cleaning, and replacement.
.CS-3A Cell Stand is specifically designed to use a variety of solid electrodes conveniently and cell accessories available from ALS. In addition, the back panel is removable, to facilitate the setting of the cable, and the stainless steel support is setting at the back, to keep space for sample handling.
Specifications and content
Cell top/test vial placement
Cell top positioner is raised, the glass cell vial is placed under the teflon cell vial cap, and the cell top positioner is lowered onto the cell vial (Fig. 4-1). The cell vial cap snaps out of the cell top positioner for easy cleaning. The teflon cell cap for CS-3A is fitted into the cell top positioner, and slided out of the positioner.

Operation
Test sample:
The flow rate of the gas, whether it is directed towards purging or blanketing the sample, is controlled by a front panel switch and knob (Fig. 4-1, No. 15 and 17). When it is toggled to the ON position, the gas flow is diverted to the purge tube and cannot be changed by REMOTE control. When switched to the OFF/REMOTE position, the gas is directed to the BLANKET tube. It must control PURGE via external control through the REMOTE connector on the rear panel (Fig. 4-2, No. 7). Without REMOTE control, thus, the ON position activates the PURGE line and the REMOTE position activates the blanket line. For REMOTE controls of the PURGE and BLANKET functions, the switch must be in the REMOTE position. The flow rate is controlled by rotating the knob labeled Test Sample. As counterclockwise rotation increases the flow, clockwise rotation decreases the flow to the cell. The LED is started to flashing when the purge function is switched on, manually or remotely.
Stir:
The CS-3A Cell Stand has a magnetic stirrer built into the unit. The stirring functions ON, OFF and rate can be controlled by the front switches. The switch under the STIR label controls whether the stirrer is ON or OFF or controls remotely (Fig. 4-1, No. 12). The ON position overrides all other commands and turns the stirrer motor on. The REMOTE position is equivalent to OFF in manual operation but is the required position for turning on the stirrer by external (REMOTE) control. The rate of stirring is controlled by the knob directly to the right of the control. The “O” position is no stirring and the stir rate increases with an increase in the position number. The LED is flashing when the stir function is switched on, manually or remotely.
