The Sonifier SFX550 is designed to bring the industry's most advanced sample-processing capabilities into any laboratory True temperature control allows the user to specify a temperature range for the sample. The Sonifier will automatically adjust the ultrasonic pulse length to prevent the sample from overheating (requires optional temperature probe). Advanced control modes include time and energy mode, energy mode measured in joules, either continuously or in individual pulses. Process monitoring on a scrollable, digital screen provides updates of key variables (including power level, energy usage, sample temperature, and experiment progress). For assured repeatability and precision on a greater scale, users can store up to 20 sample-processing programs. Program parameters include; continuous or pulsed ultrasonics; time, energy, or temperature control modes; pulse on-time/energy, off-time and total on-time/energy; or amplitude as a percentage. Microtip limit is 70%. Other accessories are also available separately. Applications: Sample preparation, cell disruption, nanoparticle disperson, mixing, homogenization, DNA, cell lysis, protein extration, and shear/chip assays. Able to accommodate sample volumes up to 1,000mL, the Sonifier SFX550 delivers up to 550 watts of power at 20kHz, and comes with a 3/4" solid disruptor horn. The Sonifier SFX550 offers the industry's simplest user interface and the most precise control over all the cricical elements of any experiment. Certifications: CSA, UL, ISO9001, ISO14001. Accessories information: The Sound proof enclosure reduces noise level up to 20db when liquids are treated ultrasonically. Especially helpful when using a cell disrupter for extended periods. Ordering information: The Sonifier Cell Disruptor is supplied with a manufacturer's three-year warranty. The unit also includes a 20kHz converter, 3/4" solid disruptor horn, power cord, manual, and wrench set.
