Best Built 1 Quart Pro Ultrasonic

A compact heated ultrasonic for lifting greasy polishing compound out of settings, chain and intricate metalwork at the bench or the front counter. The Best Built 1 Quart Pro Ultrasonic delivers industrial-grade cleaning power in a counter-friendly footprint. Tested head-to-head against comparable units using the aluminum foil test, this machine produced noticeably more perforations, a direct indicator of superior cavitation energy. For busy jewelry shops that need to remove greasy polishing compounds from tight settings and intricate metalwork quickly and completely, this unit sets a high bar for its size.

Digital controls are illuminated and straightforward: a power button, a heater on/off button, and a timer button that cycles through 1, 3 and 5 minute cleaning intervals. Continuous mode is intentionally omitted because 95% of ultrasonic cleaning is accomplished within the first 30 seconds and limiting run time protects delicate items from over-exposure. The built-in heater reaches up to 149°F (65°C), and warm solution consistently produces the best cleaning results.

Suited to personal use, front-counter display cleaning, or as the first professional-grade ultrasonic in a small shop.

Notes

• Do not place items directly on the tank bottom. Always use a basket. Contact with the tank bottom can damage transducers and will void the warranty.
• Do not operate in continuous mode. Maximum recommended cycle is 5 minutes. Most cleaning is complete within the first 30 seconds.
• Keep the tank topped off. Operate with at least 3/4 tank capacity; 7/8 full is optimal.
• Use non-ammoniated, non-flammable ultrasonic cleaning solution only. Pre-mix concentrates with water before adding to the tank.
• Degas before use: run the unit with solution for a few minutes before cleaning items to improve performance.
• Safe materials for ultrasonic cleaning generally include gold, silver, platinum, diamonds, rubies, sapphires, amethyst and citrine.
• Do not clean soft or porous stones such as emeralds, opals, turquoise, pearls, amber or ivory because ultrasonic waves, heat or temperature changes may cause damage.
• Ultrasonics do not remove tarnish.
• Watches: Do not submerge watch movements. Only metal bands may be cleaned, using the included holder positioned so the watch head remains above the waterline. Never place a non-waterproofed watch in the tank.

Warranty: 1-year manufacturer warranty; 2-year warranty on the transducers.
