ULTRASONIC PROCESSORS FOR SMALL AND MEDIUM VOLUME APPLICATIONS 500 and 750 Watt Ultrasonic Processor - 250 microliters to 1 liter* Real time display Digitally displays the actual amount of energy in Joules (watts x seconds) that is being delivered to the probe. Digitally displays the actual amount of power in watts that is being delivered to the probe. □ Automatic Tuning and Frequency Control Eliminates the need for constant adjustment of the power supply. □ Microprocessor Based and Programmable Digital accuracy assures adherence to the most exacting protocol. □ Automatic Amplitude Compensation Ensures uniform probe amplitude regardless of the varying loading conditions encountered during the processing cycle. □ On Demand Real Time Display Provides a window on the process. No more assumptions. No more approximations. Pressing a button enables all set and run parameters to be continuously displayed on the screen, providing instant operating mode confirmation without process □ Variable Power Output Control Allows the ultrasonic vibrations at the probe tip to be set to any desired amplitude. Selected output level is clearly displayed on the screen. □ Ten Hour Process Timer Controls the processing time from 1 second to □ Elapsed Time Indicator Monitors both the elapsed time and the duration of □ Independent On/Off Pulser Enables safe treatment of temperature-sensitive samples at high intensity, and provides mixing by repeatedly allowing the sample to settle back under the probe after each burst. Both on and off cycles are independ- ently controllable from 1 second to 59 seconds. Menu driven fill-in-the-blank prompts provide intuitive guidance through all functions. □ Smallest Footprint In Its Class Ultra-compact design eases emplacement and opti- mizes bench space.
