Elmasonic Xtra 120 Ultrasonic Cleaner – 14.2L Heated Tank

Most rigid items that need precision cleaning — jewellery, watch parts, dental and medical instruments, optical lenses, electronics PCBs, automotive components, lab glassware, firearms, and engineering parts. The right model depends on your application: Elmasonic EASY for general workshop use, P series at 80 kHz for delicate items, X-tra ST for heavy-duty industrial work. If you're unsure, send a sample part to info@elma-ultrasonic.co.nz and we'll run a free cleaning trial.

Avoid items with delicate coatings, soft or cracked stones (pearls, opal, turquoise without testing), gem-set jewellery with loose settings, and anything with battery seals or unsealed electronics. Some painted finishes can soften in heated baths. When in doubt, test a small area first or ask the team for guidance — we've cleaned most things over the years.

Pick a tank around 20% larger than your largest item to allow proper cavitation. For frequency: 25–37 kHz suits general workshop, automotive, and industrial work; the P series at 80 kHz is gentler on soft stones, electronics and intricate parts; dual-frequency P models give you both. The Auckland team can recommend the right model if you describe your typical part and contamination — email info@elma-ultrasonic.co.nz.

Yes. Send a representative part to info@elma-ultrasonic.co.nz with a quick note about your application. We'll clean it on the recommended Elma equipment, send it back, and let you judge the finish before you commit. It's the best way to choose with confidence.
