Professional Ultrasonic Cleaner for Small Items

The Metra M9B1302 operates at a 48KHz frequency to clean jewellery, eyeglasses, dentures and watch bands. Its 350ml stainless steel tank holds multiple pieces at once for 360° cleaning. Two timer modes handle routine refreshes or heavier grime. It suits owners of small valuables who want a simple countertop device.

Cleaning Limits of 48KHz Ultrasonics

The 48KHz frequency targets oils, lotion residue and tarnish in crevices without aggressive force. It will not strip heavy corrosion, baked-on carbon or thick scale from industrial parts. The 350ml capacity restricts use to objects that fit fully submerged. Larger items like full bracelets or tool bits may exceed the tank dimensions.

Simple One-Button Setup

Place the unit on a flat surface, add water and optional solution, then press the single button to select a 5 or 7 minute cycle. Non-slip rubber feet dampen vibration noise during operation. The most common issue is forgetting to submerge items completely, which leaves upper sections uncleaned. The SUS304 tank resists rust but should be dried after each use.

Questions about this item

Which capacity should I choose for cleaning multiple items at once?

The 350ml tank holds eyeglasses and several pieces of jewellery together, so a single 350ml unit covers most personal cleaning needs.

What does the 48KHz frequency mean for everyday cleaning?

48KHz gives a balanced cavitation action that removes oils and grime from small crevices without damaging delicate items such as retainers or watch bands.

How does the ultrasonic interface affect cleaning performance?

The 48KHz ultrasonic transducer drives 360° cavitation throughout the 304 stainless steel tank, ensuring uniform cleaning across all submerged surfaces.
