Edwards Auto 306 Cryo Evaporator

This is a resistive heating evaporator configured deposition of Chromium and Gold, both at ambient temperatures and onto heated substrates. It features a 3 kV plasma generator for substrate cleaning prior to deposition, a film thickness monitor, rotating sample support and a microprocessor controlled cryo vacuum pumping system so that high vacuum can be reached to enable contaminant free deposition.

When applying to use this instrument please include a brief summary of the experiment to be completed, along with an explanation of the ultimate aims of the project being undertaken.

Bio-Rad PT7125 Barrel Plasma Etcher


This is a 150 W 13.56 MHz cylindrical plasma chamber designed to produce an isotropic etch. It can be used for oxygen plasma surface treatment including removal of organic materials (i.e. cleaning silica surfaces) and causing hydrophilic/hydrophobic conversions of both plastics and inorganic materials. Evacuation of the chamber is achieved by a two stage vacuum pump. Automatic tuning of the chamber impedance matching network enables the reflected power to be kept to a minimum. Processing parameters (pressure, power and gas flow rates) can be monitored continuously to achieve a reproducible treatment, the plasma can be extinguished automatically after a predetermined time using the process timer.

ľAutolab type II potentiostat/galvanostat


This is a computer controlled compact potentiostat/galvanostat for electrochemical research and electroanalysis in conjunction with the FTIR, Ellipsometer and SPM. It features an Analog integrator and can supply a maximum current of 80 mA and can perform almost all elelctrochemical techniques. The ľAutolab II is controlled with powerful Windows based software that allows the user to do perform a wide variety of electrochemical techniques as well as data analysis.
