Elma Elmasonic P300H ultrasonic bath with heating, 37/80 kHz, 28 l, 1013810

The powerhouse of the P-Series: Elmasonic P300H for the most demanding applications

When it comes to maximum capacity and technological precision in the laboratory or in industrial production, the Elmasonic P300H is the first choice. As the largest benchtop unit in Elma’s renowned P-Series, it offers a tank volume of 28 litres, providing ample space for bulky components, large glassware or the simultaneous processing of large sample quantities. The ‘P’ stands for ‘Professional’ – and that is exactly what this unit delivers: switchable multi-frequency technology, intelligent operating modes and a robust design engineered for continuous operation in research, medical technology and quality assurance.

Multi-frequency technology: two devices in one

The Elmasonic P300H’s technological USP is its dual-frequency control. At the touch of a button, you can switch between 37 kHz and 80 kHz. The 37 kHz frequency is the workhorse for standard cleaning: it generates powerful cavitation bubbles that effortlessly remove even the most stubborn contaminants – such as oils, greases or polishing pastes – from surfaces. Switch to 80 kHz and the cleaning process changes fundamentally. This high frequency generates tiny cavitation bubbles that penetrate deep into the finest capillaries, boreholes and complex geometries. This mode is also so gentle that even extremely delicate micro-instruments or electronic components can be cleaned safely and without damaging their surfaces.

Maximum process control through Pulse, Sweep and Degas

The Elmasonic P300H is far more than a conventional cleaning bath. It is a multifunctional tool for sample preparation. The integrated Pulse mode allows a brief increase in ultrasonic peak power to up to 1520 watts – ideal for treating extremely stubborn contaminants or poorly soluble samples. The Sweep function ensures an absolutely uniform distribution of ultrasonic energy throughout the entire 28-litre tank by means of continuous frequency modulation. ‘Dead zones’, where no cleaning takes place, are thus a thing of the past. The Degas function is available for the rapid degassing of HPLC solvents or fresh cleaning fluids, eliminating cavitation barriers caused by dissolved gases in record time.

Ergonomics and industrial durability

Despite its impressive size, the Elmasonic P300H remains intuitive to use. The digital display shows setpoint and actual values for temperature and time simultaneously, so you can keep an eye on the process status at all times. The ultrasonic bath is made of special, cavitation-resistant stainless steel, which ensures a long service life under intensive use. A handy ball valve on the side allows for the quick and hygienic draining of the used cleaning fluid. Safety is ensured by dry-run protection for the heating element and an automatic safety shut-off after 12 hours of operation.
