Argolab DU-45S Digital Ultrasonic Bath 4.5 L

4.5-litre digital ultrasonic bath with integrated Sweep technology and dual-frequency operation at 40/28 kHz. Temperature, power, time and operating mode are all independently controlled—suited to laboratories where process consistency matters.

Functions and Control

Backlit LED display provides a clear, simultaneous readout of current and set temperature, countdown timer, power level and operating frequency.

• Sweep: continuous frequency modulation to eliminate fixed cavitation nodes and improve treatment uniformity across the tank
• Pulse: intermittent ultrasonic cycles—useful for heat-sensitive samples where continuous sonication is unsuitable
• Degas: rapid degassing of solvents and solutions prior to analysis or chromatographic use
• Timer: adjustable from 1 to 99 minutes
• Temperature control: +5 °C to +60 °C range, 200 W heating element
