Equipment in Microbiology Core:

Short Description: Fisherbrand™ Model 705 Sonic Dismembrator is a powerful ultrasonic device (sonicator) designed for cell disruption, sample homogenization, protein or DNA/RNA extraction, and nanoparticle dispersion.

Masiu fotometras 2MPProduser: Fisher Scientific

Equipment Information: 

Functions: 

  • High-frequency ultrasonic generation (~20 kHz)
  • Amplitude adjustment from 1 % to 100 %
  • Programmable cycles and pulse mode
  • Timer: from 1 second to 99 hours
  • Energy measurement (watt meter, cumulative energy in joules)
  • Touchscreen with program memory (up to 10 programs)
  • Overload protection and temperature monitoring (with probe)

Capabilities:

  • Power: 700 W
  • Sample volumes: from 0.5 ml to 250 ml
  • Pulse and continuous processing modes
  • Compatible with various probes
  • Highly precise energy delivery and reproducibility

Purpose / Usage:

  • Cell disruption
  • Protein and DNA/RNA extraction and shearing
  • Homogenization and solution mixing in the laboratory
  • Nanoparticle dispersion
  • Sonochemistry applications (ultrasound-assisted chemical reactions)
  • Applications
  • Cell biology and molecular biology laboratories
  • Biotechnology and pharmaceutical research
  • Academic and industrial research requiring precisely controlled ultrasonic processing

Operating Principle:

  1. The ultrasonic generator produces high-frequency vibrations (~20 kHz).
  2. The vibrations are transmitted through a transducer to the sonotrode (probe) immersed in the sample.
  3. The probe causes sample vibrations, creating cavitation – formation and collapse of tiny bubbles that disrupt cells or larger molecules.
  4. Amplitude and pulse settings are adjusted according to sample sensitivity, ensuring efficient yet safe processing.
  5. If a temperature probe is used, the sample temperature can be monitored and controlled to protect proteins or other sensitive components.
