Recently analytical electrochemistry has progressed dramatically. There are a number of reasons for this progress system. Operation interface becomes more user friendly and its reliability is improved. The use of solid electrodes has also been significant and popular among chemists. CS-3A Cell Stand is specifically designed to use a variety of solid electrodes conveniently and cell accessories available from ALS.
The CS-3A Cell Stand is adopted with CHI series Electrochemical Analyzers and 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.
Improve your CV measurement performed with Microelectrode
The measurement current value using Microelectrode is very small, therefore it becomes vulnerable to external noise. CS-3A cell stand can avoid the experimental irregular result caused by external noise and improve your measurement.

The CS-3A Cell Stand is applicable for either 100 V or 240 V (50-60 Hz) power supply. Using power switching regulator, the Cell Stand can set up any place without any modification.
Power cord connection
One should push the socketed end of the power cord into the port located in the back panel (See Fig. 2-1). After the connection, power switch should be "ON". This switch is labeled with a “O” and “|”. When in “O”position, the power is OFF and when in “|”, the power is ON. You make sure the power switch at the ON position. If there is any problem for the power ability, it is better to check the fuge whether it is properly installed. In any case, the fuge will be broken up if power overflows.
|Figure 2-1. Power switch (1) and fuse folder under power cord connector (2)|
As shown in Fig. 2-1, the fuse is located under power control connector. Pull the fuse holder, and check whether it works or not. If it does not work, it should be replaced with new one.
The CS-3A gas purge and stirring can be controlled by the ALS/CHI Electrochemical Analyzer. The control line is 25 pin cable (Cat No 010880 CPEE interface cable) between the remote connector on the rear of the Cell Stand and the cell stand connector on the rear panel of the ALS/CHI Models (See Fig. 2-2). The electrode leads are connected to the ALS/CHI Models by inserting cell connector on the end of the cell lead cable into the cell input connector on the rear panel of the ALS/CHI Models.

Cell lead connection
The cell leads are passed into rear panel of CS-3A Cell Stand, and see Fig. 2-3a to 2-3c. Each of aligator clip is passed through the hole carefully.

After passing the electrode leads and connecting the communication cable of USB or RS-232C with PC, the electrode leads and control line cable are connected between ALS/CHI Models and CS-3A Cell Stand.

Gas inlet connection
The CS-3A Cell Stand package includes a tygon tube and a gas line fitting. One end of the gas line fitting is nipple, the end of which pushes into the tygon tube. The other end of the fitting connects to the 'GAS IN' port on the rear panel of CS-3A (Fig. 3-1). To attach the line, you can simply push the connector into the port. A retaining clip will snap into place. The open end of the tygon tube is connected to a regulated gas supply. The inlet gas pressure must not exceed 35 kpa. To remove the tube from the Cell Stand, squeeze the retaining ring tab against the connector, and then pull the tube and connector away from the Cell Stand.
The electrode lead wires are coming through the back panel of CS-3A. The connector is tightened by screw. Simply push the connector over the corresponding pin on the electrode to make the connection. The aligator clips are derived from 3 different colors coded to the electrode (Fig. 3-2).
Purge/ blanket lines
CS-3A Cell Stand has the ability to purge the sample solution with an inert gas. The purging can remove oxygen by bubbling an inert gas, typically nitrogen, helium or argon, through the solution. The blanketing function is to maintain an inert atmosphere above the sample to keep oxygen or air components from reentering the sample solution.
The purge/blanket lines are the two plastic tubes coming out of the cell top positioner. The two larger 1/8' lines are labeled 'Test Sample'. To insert the Teflon lines: place on a flat surface, press purge line into smaller opening of Teflon cap. The blanket line is pushed into the smallest hole in the center of the Teflon cap. The blanket line should extend to just beyond the bottom of the teflon cap.
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.
