Branson 1/8" Double Step Microtip Microtip probes are available in tapered and stepped configurations and are designed to process samples contained in small diameter vessels at extremely high intensity (refer to chart for recommended volumes). Tapered microtips screw into standard 1/2" step horns with tapped ends. The double stepped microtip consists of a coupler and a stepped tip and screws directly into the converter. It has lower amplitude than the tapered tip, but is capable of reaching into small diameter vessels of greater depth and can process solutions down to 0.1 mL. Typical Applications: Micro-tapered is recommended for processing spores, fungi, yeast, muscle, and connective tissue. Double Stepped Microtip –is recommended for red and white blood cells, tissue culture cells, HELA cells, and cells which have a low to medium resistance to breakage. Attaches to converter only.
