Lexa Sterilizer. A Smarter Approach to Dental Sterilization.
Large capacity meets incredible efficiency in the Lexa Sterilizer by W&H. Combine loads, customize cycles and achieve sterilization best practices with an intuitive, easy to use system. Patented technology delivers bone-dry loads—helping protect your patients and mitigate risk.
Large Capacity
Lexa’s 11” diameter chamber holds four large trays and up to four levels of cassettes. Sterilize and dry 18 lbs. of dental instruments in as little as 30 minutes.
Sterile Process
Closed-door vacuum drying keeps the door locked for the entire cycle, while patented steam-condensing vacuum technology produces bone-dry loads.
Universal Rack
Lexa’s universal rack offers flexibility. Mix loads of cassettes and pouches as well as capability for vertical and horizontal cassette placement. No need for additional racks.
Lexa Sterilizer Features
Universal rack. Load vertically or horizontally, or mix trays and cassettes, without additional racks.
Single-use water system. Water is never reused; separate tanks hold clean and used water.
Efficient air removal. Dynamic, repeated steam injections remove air rapidly.
HEPA filter. Allows only clean air into the chamber.
Pre-programmed cycles. Choose from three custom cycles or six FDA cleared, pre-programmed cycles.
Customize by load. Settings for pouches or cassettes ensure the fastest cycle for any load.
Intuitive LCD display. Easy to operate; includes a low water reservoir alert.
Easy traceability. Manage and document each sterilization cycle initiation and load release.
Accurate documentation. Store sterilization cycle data on a thumb drive; easily update software.

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 |
|---|---|---|---|---|
| Unwrapped | 270º F /132º C | 4 min. | 26-39 min. | 18 lbs. / 8.1kg |
| 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 |
| Pouches & Wrapped Cassettes | 270º F /132º C | 4 min. | 53-64 min. | 11 lbs. / 5.0kg |
| Wrapped Cassettes | 270º F /132º C | 4 min. | 58-71 min. | 14 lbs. / 6.3kg |
| Low Temperature | 250º F /121º C | 30 min. | 73-79 min. | 5 lbs. / 2.3kg |
*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.
