New generation microforge

The Neurolog system has been designed by Digitimer for optional instrumentation flexibility when processing electrophysiological signals. The system is modular with more than 50 types of interchangeable modules on offer for signal conditioning, amplification, tinting, averaging, integration and so on. Only those modules required to perform a particular function need to be inserted into the common rackmountable case. Because it is built and functions as a system, input and output levels, impedances, connectors and so on, of different modules are compatible, eliminating problems often encountered when interconnecting pieces of equipment of diverse origin. Contact number: +44 (0)1707 328347, UK The analysis of brain tissue samples is simplified by the brain slice chamber from Intracel, which is designed to maintain isolated living tissue in vitw. This allows stable electrophysiological recordings to be made from the tissue preparation. Both interface and submerged methods of slice maintenance are accommodated. The machined acrylic chamber incorporates a low noise heater, and permits the height of perfusion fluid to be easily adjusted. Versions are available for heating and cooling above and below ambient temperature, the medium being preheated or cooled by the system, before contact with the tissue. The system consists of the chamber together with a controller with an LCD temperature read out.
