How to Use Onset EZ

At Onpharma, we want to ensure you get started successfully when using the Onset EZ Pen. The following video provides an overview of how to use the Onset EZ Pen. 

Buffering with the Onset EZ Pen

Insert a dental local anesthetic cartridge into the open end of the Onset EZ Pen until there is an audible "click."

Buffer the cartridge by rotating the green Actuator Knob 1/2 turn (180 degrees) in the direction of the arrow until it “clicks”.

Release the buffered cartridge by depressing the two Release Tabs. Use the buffered anesthetic immediately.
