PRESSURE CHAMBER FOR MICROELECTROPHYSIOLOGICAL TECHNIQUES (CAISSON DE COMPRESSION POUR TECHNIQUES MICROELECTROPHYSIOLOGIQUES)

Abstract

This research program on the effect of hyperbar gases on isolated nerve cells of 'Aplysia' has involved the study and construction of a pressure chamber. The chamber is mainly composed of a cylindrical tube, with 2 glass portholes allowing the illumination and observation of the biological preparations, and 2 moveable doors with a quickclosing system which permit micromanipulation. Electrical connections assure all the various remote controls. Two taps, purge and stop, a manometer and a safety valve complete the equipment of the chamber. The equipment meets the requirements of microelectrophysiological techniques and can submit the preparations to constant pressures of as much as 6 bars.
