Overview of Ultrasonic Probe Sonicators

Ultrasonic probe sonicators are versatile devices designed to utilize high-frequency sound waves for various scientific and industrial applications. These devices leverage mechanical vibrations to induce cavitation and shear forces in liquids, facilitating diverse processes such as cell disruption, nanoparticle dispersion, and emulsification.

Applications of Ultrasonic Probe Sonicators

Ultrasonic probe sonicators are critical in numerous fields including biotechnology, chemistry, and materials science. Key applications include:

• Cell Disruption: Efficiently breaking cell walls for DNA, RNA, and protein extraction.
• Nanomaterial Dispersion: Homogeneously dispersing nanoparticles in solvents.
• Emulsification: Creating stable emulsions for pharmaceutical and cosmetic formulations.
• Degassing: Removing dissolved gases from liquids.

Technical Specifications and Parameters

Ultrasonic probe sonicators operate at frequencies typically ranging from 20 kHz to 80 kHz, with power outputs varying between 50 Watts to over 2000 Watts, depending on the model and application. High-frequency models generate finer cavitation bubbles, enhancing delicate processes like protein sonication, while lower frequencies are ideal for robust applications such as cell lysis.

Optimal sonication parameters are critical for process efficiency and include:

• Amplitude: Adjustable typically between 10-100 microns, affecting the intensity of cavitation.
• Time: Duration of sonication, impacting the extent of material disruption.
• Pulse Mode: Alternating periods of sonication and rest to manage sample temperature.
