1. Name of facilitated equipment:
HIGH INTENSITY ULTRASONIC PROCESSOR
Catalog name: VCX 750
Producer: Sonics & Materials, INC
Equipment type: facilitated equipment
Date of purchase: 2008
Sonicator VCX 750
2. Domains of activity:
• VCX 750 is a versatile sonicator suitable for various laboratory
application such as: solutions, dispersions, nanoparticles etc. It presents
new generation controls which allows all set and run parameters to be
continuously displayed on the screen, providing instant operating mode
confirmation without process interruption.
• Allows the ultrasonic vibrations at the probe tip to be set to any desired
amplitude. 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.
3. Technical characteristics / performances:
• Net power output: 750 W
• Sealed Converter: Piezoelectric lead zirconate titanate crystals (PZT)
• Standard Probe: Tip diameter 13 mm with threaded end and replaceable tip
• Processing capability: 10 ml to 250 ml
• Length: 136 mm
• Weight: 340 g
