Filament Gauge Material Application
H2 Large Platinum/Iridum H2 Large Platinum/iridium Can be formed into a variety of shapes (reformed) for fabrication of pipettes up through the 100-200 micron range. Reforming the filament can result in a greater heated surface area to present to the pipette tip. For large pipettes, it is best used with the 10¥ standard objective on the model H602 microscope (optional Filament Adjustment Assembly required) or the optional 25¥ LWD objective.
H3 Medium Platinum/Iridum For polishing patch clamp pipettes or larger pipettes up to 3-5 micron
H4 Small Platinum/Iridum For polishing patch clamp pipettes
