Radnoti Glass Technology now provides the researcher with several combinations of interchangeable tissue supports and stimulating electrode inserts designed for isolated tissue research. The combination tissue support and stimulating electrode inserts are designed for 10ml and larger Radnoti Tissue Baths. This design allows adjustment of electrodes both vertically and horizontally, permitting precise placement of leads in relation to the sample. For the experimenter using tissue strips or spirals, the straight lead (160152-11), zig-zag lead (160152-12) or the coil leads (160152-13) may be used depending on user preference. For users of very small samples, the coil lead (160152-13) or (160152-15) flat lead configuration are recommended. The L-type (160152-14) tissue combination support is designed to stimulate rings cut from blood vessels. The ring is 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. The modular design allows researchers to have a single standard electrode holder and change electrode leads when changing experimental protocol or to repair electrodes.
