Defend® Ultrasonic Enzymatic Tablets
These easy-to-use enzymatic tablets dissolve in a gallon of water in under a minute to create a powerful and effective ultrasonic cleaning solution. Made from a biodegradable, non-chlorine, non-corrosive formulation that contains fast acting protease enzymes. The solution will greatly assist in the removal of blood, bone, tissue, food particles and other soils that may be resistant to chemical detergents. Virtually eliminates handling and storage of heavy liquid concentrates. Contains a pleasant fragrance and is a neutral pH. May also be used as an instrument pre-soak or as an evacuation system cleaner.
Can tablets be cut in half to make less solution? We do not recommend doing this as it is not stated in the instructions for use. Instructions state to use 2 tablets to one gallon of warm tap water. Or, one tablet for two quarts or less.
Is there expiration/shelf life on tablets? Yes, they have an expiration date of 30 months from manufacturing date.
How long does the solution stay active? OSHA recommends that the solution be changed daily and depending on daily bio-burden build up even more frequently as necessary. However, internal testing shows that the solution can be premixed and stored in a re-closable jug and be active up to 30 days.
What exactly does it clean? It cleans dental instruments. The enzyme breaks down the protein (blood and oral debris) that you find on used instruments. This solution is placed in an ultrasonic cleaner that creates ultrasonic waves to help with debris removal.
Can I mix the tablets with anything other than water? NO
Will the solution clean more effectively if I saturate it with more tablets? No supporting studies are available to confirm
Are there any special requirements to dispose of the solution? Is it allowed in with general waste water? The SDS for this product states to arrange disposal in accordance to the EPA and/or state and local guidelines as it can vary from state to state.
How many times can you use the solution before you need to change it? Solution should be changed every 24 hours unless it becomes cloudy within that time frame, then the solution should be changed.
How long do the instruments need to soak? 10 minutes
