Instrument: Fisher Scientific 550 Sonic Dismembrator


Biological Instrumentation


1118 Chevron Science Center



The 550 sonic dismembrator is used to disrupt and rupture prokaryotic and eukaryotic cells during protein and nucleic acid purification protocols. In addition, it is used for efficient mixing in nanotechnology applications including dispersion of carbon nanotubes and polymers. Two horns are available, one for volumes below 50 mL and one for volumes above 50 mL. The generator power is continuously variable with reflected power feedback from the probe.
