Description
We are passionate about supporting jewellery makers at every stage of their journey. The Bench Essentials range has been created with beginners and students in mind, offering reliable, affordable, and high-quality essentials to help you build skills and confidence at the bench.
The Bench Essentials by Cooksongold Ultrasonic features a 1.8-litre capacity tank, making it an ideal solution for removing heavy dirt, grease, and fingerprints from jewellery. It effectively cleans hard-to-reach areas and is powerful enough to remove stubborn residues, including polishing compounds.
This stainless steel ultrasonic is a durable machine and is manufactured with strong industrial transducers giving out 40KHz of power, rather than the weaker water transducers which are common in other Ultrasonics.
The lid features a moulded handle making the Technique Ultrasonic easy and safe to access.
