L&R Ultrasonics.

The L and R history page says the company was founded in 1930 by Max A. Lazarus Sr., a printer who formulated cleaning solutions for mechanical watch and clock parts and later for jewelry. By 1960, the same page says, the firm introduced ultrasonic cleaning to dental offices, dental laboratories, and medical instrument care, along with solutions for instruments and dentures. The address printed there is 577 Elm Street, P.O. Box 607, Kearny, New Jersey 07032, telephone 201-991-5330 and fax 201-991-5870.

The CEO message calls the business a fourth-generation family-owned company and says the cleaning process was created in Macon, Georgia, before the Kearny plant described on the history page. That message also says systems are made in the United States and cites ISO 9001:2015, ISO 13485:2016, and a 2.5-year warranty on systems. Those certification and warranty lines are the company's statements. Ask for the current certificate if a surveyor wants the document.

The history page says today's markets still include dental and medical instrument cleaning and also industrial, scientific, and law-enforcement work. Dental buyers are purchasing a cleaning bath and chemistry that sit before steam sterilization, not a sterilizer. A dirty instrument that leaves the bath still has to be rinsed, dried, packaged, and sterilized under the office's written protocol.

The company site identifies the Association for Dental Safety and NQA among the marks on the contact block. It does not, on the pages reviewed here, print a single dental model number that covers every tank size. Ask the dealer which tank volume, basket, and solution match the cassette system you already use. A jewelry solution and a dental-instrument solution can share a brand and still be the wrong chemistry for a hinged cassette. The history page also says the firm remained involved with customers after the product line expanded into industrial and law-enforcement cleaning, so a quote should say dental instrument use in writing.

L&R suits a sterilization room that wants a US-built ultrasonic bath ahead of the autoclave. Compare baths on the ultrasonic cleaner guide.

The sterilizer is a different machine. After the bath, packages go into a steam sterilizer, which is covered on the sterilizer guide. L&R's pages reviewed here do not describe an autoclave.

Ultrasonic energy and chemistry remove debris. They do not replace a sterilization cycle. Write the bath time, the solution, and the rinse into the same procedure that names the autoclave cycle.

L&R also serves jewelry, watch, and industrial users. A solution formulated for a watch movement is not automatically the solution for a hinged dental cassette. Stay on the dental instrument label.

Call the Kearny office at 201-991-5330, the number printed on the history page, and ask for dental tank recommendations rather than a generic industrial unit. Confirm voltage, heater, and drain before the tank arrives.

The family-ownership statement is on the CEO page. It does not list a corporate parent. If a dealer invoice uses a different seller name, ask whether that seller is an L&R distributor or the factory.
