Elma Elmasonic EASY ultrasonic cleaner R
This compact, round ultrasonic cleaning device is a versatile solution for laboratories, workshops and industrial applications in which a wide range of cleaning steps and sample preparation must be carried out precisely and reliably. Thanks to its robust stainless steel construction and on-demand control, many users rely on this unit to complete demanding cleaning tasks in the shortest possible time. Test results similar to those of the [Elma Elmasonic S 10H] show that a homogeneous sound distribution is achieved with a wide range of liquid volumes, which minimizes incorrect cleaning and saves time, water and cleaning concentrates.
Powerful technology for precise and fast cleaning
The round design of the device enables efficient use of the available space and at the same time offers more even sound emission inside. With an integrated 37 kHz ultrasonic frequency (control range -2.5 / +5.5 kHz), the system ensures thorough yet gentle results for surface cleaning, degreasing, particle removal or sample preparation. Users benefit from four individually selectable ultrasonic modes:
- general cleaning sweep mode: For general cleaning tasks, ensures an even distribution of cavitation in the cleaning bath.
- sieve cleaning mode: Increases the ultrasonic intensity to quickly and effectively remove even stubborn dirt from test sieves, for example.
- sample preparation mode: Switches between sweep and pulse, ideal for dissolving, dispersing and mixing.
- degas mode: Optimizes the rapid degassing of HPLC solvents and thus reduces interfering bubble formation.
In addition, the membrane keypad with LED displays enables intuitive operation. The automatic shutdown of all operating modes when the temperature exceeds 90 °C protects the device and the items to be cleaned from possible thermal damage. The system also reacts with a wake-up function after a long period of non-use so that it remains ready for use at all times.
Technical key points:
- Filling volume: 6.0 liters (50 R) or 69.0 liters (350 R)
- Working volume: 3.0-5.0 liters (50 R) or 59.0 liters (350 R)
- External dimensions (W x D x H): 345 x 295 x 345 mm (50 R) / 675 x 795 x 505 mm (350 R)
- Effective ultrasonic power: 150 W (50 R) / 650 W (350 R)
- Ultrasonic peak power: 600 W (50 R) / 2600 W (350 R)
- Protection class: IP20
An integrated drain tap (350 R only) makes it easier to empty the cleaning fluid. On the 50 R, the lid can be used upside down to serve as a drip tray for the cleaning basket. In addition, the reliable electronics are splash-proof and designed for long-term use. The cover helps to reduce noise emissions and minimize contact with released particles.
Certifications and standards
Elma appliances meet high industry standards in terms of safety, manufacturing process and material quality. The splash-proof stainless steel casing and extensive safety functions help to ensure compliance with regulatory requirements. At the same time, they impress with reliable process stability in continuous operation.
Application examples
- Cleaning highly sensitive small parts: Ideal for metallic components such as injection nozzles, valves or special precision tools to remove oil and dirt particles.
- Processing of chemical samples: The sweep and pulse modes intensively mix and homogenize liquids, for example when forming emulsions or suspensions in laboratory applications.
- Degreasing and preservation: In the jewelry and watch industry, suitable cleaners can be used to clean the surface of products without leaving any residue so that protective coatings can then be applied.
- Maintenance of test sieves: The sieve cleaning mode in particular offers increased ultrasonic intensity, which removes even stubborn layers of dirt and increases the service life of the sieves.
FAQs
Is a short contact time sufficient
?
Yes, in many cases a short sonication is sufficient, especially if pulse or sieve cleaning mode is selected. However, longer cycles may be advisable for heavier soiling.
What happens if the temperature in the bath rises excessively?
As soon as the bath temperature exceeds 90 °C, the ultrasound automatically deactivates. This protects both the appliance and sensitive items to be cleaned.
Can I use pH-neutral detergents?
You can work with pH-neutral or slightly alkaline/acidic cleaners without any problems. However, make sure that the cleaner is suitable for the residue to be removed and does not attack the material to be cleaned.
Should I cover the appliance during operation?
The lid or cover provided is recommended to reduce evaporation and noise emissions. This also reduces heat loss, especially during long cleaning cycles.
Conclusion
With its versatile ultrasonic modes and carefully tuned frequency, this system offers highly effective yet gentle cleaning for applications ranging from analytical laboratories to industrial manufacturing. The robust design and adjustable fill level not only enable efficient results, but also easy handling and flexible use. In particular, the combination of user-friendly controls, automatic safety shutdowns and powerful ultrasonic transducers guarantees a high level of reliability - a reliable partner for daily cleaning and sample preparation.
