The Megaruptor® was designed to provide researchers with a simple, automated, and reproducible device for the fragmentation of DNA in the range of 2 kb - 75 kb. Shearing performance is independent of the source, concentration, temperature, or salt content of a DNA sample. Our user-friendly software allows for two samples to be processed sequentially without additional user input and without cross-contamination. Just set the desired parameters and the automated system takes care of the rest. Clogging issues are eliminated in this design.
