Branson Sonifier® ultrasonic cell disruptor / homogenizers              are versatile laboratory units suitable for a broad range of       liquid processing applications such as: Biological cell disruption / homogenization Emulsification Reaction acceleration Dispersion Fine mixing Degasing Each model consists of a power supply, a converter, and a mechanical probe or horn. The power supply/converter changes standard electrical power to high frequency mechanical energy, which is then applied to the horn, where it is further amplified for use (often with specialized accessories). KEY FEATURES Sonifier® S-450A analog ultrasonic processor includes many features to make the technician's work easier. 400 Watt (S-450A) Auto tuning for optimum performance under varying conditions Power output control to match power to the application Continuous or timed (0-15 minutes) operation to free technician for other activities Pulsed mode to minimize heat generation in thermally-sensative samples Broad process range from 1ml to over 500 ml per sample Power output meter to monitor power and permit reproducability Compact design limits required counter space Sloped front control panel for visibility and easy control access Includes a high-efficiency converter which requires no internal cooling Supplied with a standard 1/2" titanium horn that is suitable for many applications A wide range of dedicated accessories to meet special needs SPECIFICATIONS   Model Part Number Input Power Output Power Dimensions Weight S-450A 101-063-198 117V,60HZ 400 Watts 7-3/8"W X 16-3/4" D X 8-3/4"H 25lbs.
