Ultrasonics clean by compressing and releasing water molecules to scrub dirt particles loose. Use this surfactant to improve the scrubbing action and reduce the friction between water molecules. You’ll see better cleaning results faster. Use only a few drops per tank. Dry powder makes 4 ounces of concentrate.
There are many reasons to check for stress in mounted lenses. Too much stress on a lens may not manifest itself until the day your patient exits a warm office building into sub-freezing temperatures and the lens implodes. Aside from viewing stress patterns you can determine axis in polarized lenses. This is a compact bench top model that you can hold in your hand. Operates using two AA batteries (included). 2-3/4" W x 2-3/4" H x 4" D.

Helpful usage tip: Plug The Hot Box into a wall timer and set it to come on an hour before you plan on seeing patients. This will give the unit enough time to get up to temperature. On first set up turn the On/Off switch to the midway point and control the temperature for each frame by raising (cooler) or lowering (hotter) the glass beads. Adjust the On/Off switch until you find the heat level you are comfortable with. The temperature adjustment is not like a quickly responding toaster as the heat is very gradual.
CAUTION: The temperature knob will be HOT to the touch. Do not use it to raise and lower the temperature of the medium bath on a per job basis.
The clean way to evenly transfer heat around eyewear. Beads measure approximately 2mm in diameter. Beads won't get caught in bevels or hinges. Each five pound container fills the Hot Box to the proper level.
"Western manufactures the Hot Box frame warmer and we have conducted many tests on which size glass beads most evenly distributes and retains the heat for more efficient operation and the avoidance of hot spots. We’ve even tried plastic beads (didn’t work). Beads that are too fine (like sand or salt) trap the heat and when combined over time with atmospheric moisture can turn the medium into a brick which can burn or scratch the eyewear. Our Performance Enhancing Glass Beads allows small gaps between the spheres for air flow and even heat distribution. Breaking with tradition, we do not offer two sizes of beads. We decided only to offer the best size at a competitive price."
