Section 1. Introduction
Finite current electrochemistry is commonly used for analytical purposes. The BAS C3 Cell
Stand is specifically designed to conveniently use the variety of solid electrodes and cell
accessories available from BAS.
The C3 Cell Stand interfaces directly with epsilon, BAS 100 series Electrochemical
Analyzers, the CV-50W and other BAS Voltammographs. The cell can be enclosed in a
Faraday Cage to minimize electrical interference. A built-in gas control allows purging or
blanketing of the sample prior to or during analysis. The magnetic stirrer allows for
controlled agitation of the sample for experiments requiring convective mass transport of
analyte to the electrode surface. The cell arm with detachable cell top allows easy access to
the electrodes for rinsing, cleaning, or replacement. The stir motor/cell vial base pivots for
easy removal and replacement of the cell vial.
The C3 Cell Stand is part of an Electrochemical Accessories Package. The package also
includes voltammetry cells, reference electrodes (silver/silver chloride), working electrodes
(glassy carbon and platinum), an electrode polishing kit, and connecting tubing.
Features • Complete package
• “Quick-connect” input gas line connector
• Manual or remote control of gas purge/blanket
• Manual or remote on-off control of magnetic stirrer
• Manual 16-position adjustment of magnetic stirrer rate
• Small volume glass cell vials
• Mounted cell top compatible with all BAS solid working electrodes
and reference electrodes
• Cell lead connects directly to all BAS electrochemical controllers
(Voltammographs or Electrochemical Analyzers)
• Standard addition port
• Open architecture for easy access to cell
• Faraday Cage available for low current measurements

Section 2. General Information
User Updates To receive product update news and valuable information related to this and other BAS
products, fill out and return the BAS Warranty Enrollment Card shipped with your C3 Cell
Stand. We would like to know who you are and how we can meet your electrochemical
analysis needs.
Technical Changes BAS may make technical changes to improve the instrument. Improvements affecting use or
maintenance will be described in supplementary pages to this manual.
Shipping Damage Damage to any part of the C3 Cell Stand during shipping should be reported immediately to
the freight handler and BAS Customer Service. Unless other arrangements have been made,
the freight handler (shipper) is responsible for all damage or breakage to the instrument and
parts. Retain the original packing box and contents for inspection by the freight handler.
BAS will replace any new instrument damaged in shipping with an identical product as
quickly as possible after the claim filing date. Claims not filed within seven (7) days after
receipt of shipment may be invalid.
Do not return damaged goods to BAS without first contacting Customer Service for a Return
Authorization Number (RA#). When a defective part is returned to BAS, the RA# immediately
identifies you as the sender and describes the item being returned. BAS refuses all
unauthorized return shipments.
Limited Warranty BAS warrants equipment manufactured by the company to be free from defects in material
and workmanship for a period of one year from the date of shipment, except as provided
hereinafter. This warranty assumes normal usage under commonly accepted operating
parameters. BAS agrees to either repair or replace, at its sole option and free of part charges
to the buyer, any parts of instrumentation which, under proper and normal conditions of use,
prove to be defective within one year from the date of shipment. Electrochemical cells and
working electrodes are warranted for 60 days. Expendable items including but not limited to
carbon paste, reference electrodes, source lights, panel lights, fuses, etc., are excluded from
the warranty. This warranty and remedy are given expressly and in lieu of all other
warranties, expressed or implied, including but not limited to warranties of merchantability
and fitness for particular purpose, and constitute the only warranty made by BAS.
BAS neither assumes nor authorizes any person to assume for it any other liability in
connection with the sale, installation, service, or use of its instruments.
All products manufactured by BAS are tested and inspected prior to shipment. Upon prompt
notification by the Buyer, BAS will correct any defects in warranted equipment of its
manufacture either (at our option) by return of the item to our factory or shipment of a

repaired or replacement part. BAS is not obliged, however, to replace or repair any piece of
equipment which has been abused, improperly installed, altered, damaged, or repaired by
others. Defects in equipment do not include decomposition, wear, or damage by chemical
action or corrosion. Shipping charges under warranty are covered only in one direction. The
Buyer is responsible for the cost of shipping to the factory if return of the part is required.
BAS shall have no liability whatsoever for special, consequential, or punitive damages of
any kind arising from the sale, installation, use, or servicing of its instruments.
This instrument is manufactured for research purposes only. Use in medical diagnosis is not
intended, implied, or recommended by the manufacturer. Use for this purpose and
accountability for the same rest entirely with the user.
Service BAS provides a skilled service staff to solve your equipment-oriented problems. For further
details, call Customer Service at (765) 463-4527 or e-mail echem@bioanalytical.com.
Following discussion of your specific difficulties, an appropriate course of action will be
described and the problem resolved accordingly. Do not return any products for service until
you have a return authorization number (RA#). Turn-around time on service can be
estimated at the time your RA# is issued, but actual service required cannot be determined
until we have received your unit and verified the problem. All correspondence and
shipments should be sent to:

Section 3. Installation
Inspection of Shipment After carefully unpacking the instrument, check the contents of the packages and inspect for
damage. Parts of the C3 Cell Stand are listed below. (This list is subject to change.) Please
refer to the packing slip with your instrument to verify the parts. Retain the shipping box and
packing material until you have fully tested the unit to be certain that no damage was
incurred during shipment.
If you discover a shortage in parts, call BAS Customer Service and describe the shortage.
Replacement part(s) will be sent immediately, subject to stock availability.

Location of C3 Cell Stand 1. Provide a surge-free power source. Other laboratory equipment such as ovens, vortex mix-
ers, centrifuges, and large motors may cause spikes in the power supply.
2. Ensure that all components of the system share the same ground circuit. This can best be
accomplished by plugging all components into a multi-outlet power strip. Plugging the
components into independent outlets can produce ground loops (current that flows be-
tween ground circuits at slightly different potentials), which can produce baseline noise.
Section 3. Installation

3. Locate the C3 Cell Stand on a stable bench. Vibrations can cause noise.
4. Select a room where temperature remains stable throughout the day. Avoid installing the
C3 near windows, air ducts, ovens, and refrigerators. Diffusion coefficients can change
by 3%/°C. A water-jacketed cell may be required for very precise work.
5. Place the C3 away from busy, congested areas. Remote, isolated areas are best for high-
sensitivity work.
6. Avoid very dry areas and areas that are carpeted. Static electricity can affect instrument per-
formance. Anti-static floormats and benchmats are useful if spiking caused by static
charge is a problem.
7. Avoid areas where radio-frequency interference is likely. Beeper-type paging devices can
be a problem in some installations.
Power Requirements The C3 Cell Stand contains a fused, self-sensing power supply which can be powered by
100-240 V (50-60 Hz). It uses two 2 Amp fuses. Power requirements are shown on the back
panel of the C3 (see Figure 2).
