American Made Ultrasonic Scaler For Over 40 Years

South East Instruments was founded in 1975 by Seymour Robinson to realize his dream of creating the finest, American-made ultrasonic scaler without sacrificing quality by outsourcing production to other countries. The end result of this ambitious dream was the Autoscaler, which immediately became a bestseller in the endodontic industry due to its high performance, premium quality, unbeatable value, and best-in-class warranty.

For over 40 years, South East Instruments has been manufacturing and servicing the Autoscaler  . In 2021, South East Instruments was acquired by Pac-Dent, Inc. and joined Pac-Dent’s growing family of dental brands. Pac-Dent is committed to continuing South East Instrument’s founding goal of producing the best ultrasonic scaler right here in the United States.
