ULTRASONIC PROCESSORS FOR SMALL AND MEDIUM VOLUME APPLICATIONS 500 and 750 Watt Ultrasonic Processors - VCX Series - 250 microliters to 1 liter* Real time display . . . □ Exclusive Energy Setpoint The energy setpoint continuously monitors the amount of energy in Joules (watts x seconds), that is being delivered to the probe, and terminates the ultrasonics when the desired amount of energy has been dispensed. 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 □ Integrated Temperature Controller Precludes harmful overheating of the sample and guarantees process integrity by terminating the ultra- sonics when the sample temperature reaches a predetermined limit. Allows process control and Time saving memory stores up to ten procedures to facil- itate protocol duplication, automate repetitive tasks, and eliminate technician-to-technician method variability. □ Microprocessor Based - Programmable Digital accuracy and repeatability assures adherence to the most exacting protocol. □ Automatic Amplitude Compensation Ensures uniform probe amplitude regardless of the vary- ing 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 interruption. □ Variable Power Output Control Allows the ultrasonic vibrations at the probe tip to be set to any desired amplitude. Selected output level is clearly □ 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 independently 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 optimizes bench space. Only 7V" x 1VI" (1 90 x 340 mm). *For larger volumes use continuous flow cell Part No. 630-0495 or VCX 1500. Laboratory stand, converter clamp and temperature probe are not included. ^ I S* SONICS & MATERIALS, INC., 53 CHURCH HILL ROAD, NEWTOWN, CT 06470-1614 USA 1-800-745-1105
