Asked before buying

Will it fit my ultrasonic unit? Obtura Spartan make the range for scalers using M3 x 0.6 threading, and offer every tip again as the E series with M3 x 0.5. This one is M3 x 0.6. Check your unit's manual first – they warn that forcing a tip with the wrong thread damages the device. The tip wrench seats it properly.

How long does a tip last? Obtura Spartan state the tips were tested to 250 reprocessing cycles to ISO 18397 without loss of performance or corrosion – but end of life is set by wear in use as well, so inspect each tip during cleaning and retire damaged ones. They also ask for very light pressure: small-diameter tips are subject to breakage at any time.
