Radnoti Glass Technology now provides the researcher with several selections in tissue support and stimulating electrode combinations designed for isolated tissue research. The combination tissue support and stimulating electrodes are designed for both the 5-10ml and the 25-50ml Radnoti Tissue Baths. The L-type tissue support (160121) is designed to stimulate rings cut from blood vessels. The ring is cut, slid on the lower support, attached to a tri-shape tissue support (158817 and 158819) and placed under tension between the two horizontal platinum wire electrodes. For the experimenter using strips or spirals, the 10mm diameter ring electrodes (ring-type 160131), or the 10mm vertically-separated zig-zag electrodes (vertical-type 160151) may be used. Radnoti also supplies hook-shaped tissue supports without electrodes (glass hooks 160170, 160171 and 160172) for muscle preparations.
