What type of dental sterilizer is Lexa?
Lexa is a tabletop steam sterilizer from W&H. It’s designed to remove air rapidly by repeatedly alternating a steam flush and a pressure pulse (SFPP). A vacuum-assisted, closed-door drying cycle follows CDC best practices for dental instrument sterilization, and produces bone-dry loads.

What are the benefits of the Lexa sterilizer?
The Lexa Sterilizer has an 11” diameter chamber with a universal rack that will accommodate four large trays, up to four levels of cassettes, or mixed loads of trays and cassettes. The patented vacuum-assisted, closed-door drying technology from W&H produces bone-dry loads in total cycle times of just 30-70 minutes. Lexa’s design is robust, reliable and easy to maintain and service.

How long does it take to run a cycle on Lexa?
Cycle duration varies by model voltage, cycle selection and load size. The total cycle time for heating, sterilization and drying typically ranges from 30 to 70 minutes.

Load Type Sterilization Temperature Sterilization Time Total Cycle Duration Maximum Load Weight

Pouches Medium Load 270º F /132º C 4 min. 43-53 min. 3 lbs. / 1.4kg
Pouches Large Load 270º F /132º C 4 min. 48-58 min. 6 lbs. / 2.7kg

*Cycle times are approximate and may vary depending on voltage and instrument loads.

What accessories are available for Lexa?
Optional accessories include kits for automatic filling and draining of the sterilizer tanks, a city water filtration system, a label and cycle report printer, and a WiFi key to connect Lexa to the office network and allow remote access via cell phone.

Is Lexa WiFi capable?
