A main deficiency in education establishments, is the provision of a low cost computer controlled electrochemical analytical workstation, with excellent software, using up to-date help-lines and workbooks. The modern computer can now be purchased at a very reasonable price and usually consists of a tower block case supporting the computer control module, a CD, hard and floppy disc modules. There is also a spare bay position available in the unit to take a spare hard disc drive unit. This can be encased in a holder with a carrying handle so that disc can be removed for security purposes. A miniature Potentiostat/Galvanostat workstation has been designed to fit in this special holder that is then supplied with power from that within the computer. A Faraday screened box fits directly onto the connectors of the unit within which is fitted a small electrochemical cell supporting 0.5 to 5.0 millilitres of solution. A miniature electrode holder is also included to measure samples down to 100 microlitres. This reasonably priced product allows a complete range of tests to be carried out, thereby educating the student in an up to-date professional way, at minimum costs.
