New Multi-Frequency Industrial Ultrasonic Cleaners Can Operate 24/7 To Clean Pharmaceutical Manufacturing Equipment, Medical And Dental Devices

Heavy-duty, multi-frequency industrial ultrasonic cleaners with stainless steel tank capacities from 1.2  to 47.6 gallons are ideal for cleaning scientific and pharmaceutical production equipment, aerospace and automotive parts, and medical and dental devices among other laboratory and manufacturing cleaning requirements.  The extra heavy-duty Elma Transsonic TI-H tanks offered by Tovatech also carry a three year warranty.

The TI-H series can operate for 24 hours a day and provides frequency options of 25/45 kHz or 35/130 kHz in a single unit. As explained by Tovatech director Dr. Rachel Kohn, “The 25 kHz frequency is used for coarse particle removal while 35 and 45 kHz are used to clean dust, grease and oils from hard surfaces. The 130 kHz option is used for gentle cleaning of sensitive surfaces such as jewelry and electronic parts.”  She adds that all TI-H units are fully power adjustable and operate in three modes: Normal, Sweep and Degas.

The Normal mode produces a stabilized frequency field that forces the ultrasonic cleaning solution to circulate and mix. Mixing, dispersing, emulsifying, and dissolving samples is most efficiently accomplished in this mode. In Sweep, frequencies are continuously shifted to ensure that ultrasonic cavitation occurs uniformly throughout the tank. Glass, metal, gem, and plastic surfaces are most thoroughly cleaned in Sweep mode. And because dissolved air in new cleaning solutions can suppress the powerful cleaning action of cavitation, Degas is used to remove it thereby assuring the most efficient cleaning.

All Elma TI-H units feature a user-friendly intuitive control panel for ultrasonic cleaning power, frequency, and mode, as well as temperature and time.  Units are heat and sound insulated; optional sound-protection covers are available.

What kind of contact lens case is best to use?

I'm really not into putting my lenses into a case that soaks the bacteria and germs that I could not clean off by simply wiping them off for 6 hours.

You are right, the ultra sonic cleaners ruin the lenses very quickly. They were used for awhile back before disposable lenses. The conventional lenses that were worn for up to a year were thicker and could stand the heat for a longer period before turning yellow. The disposable lenses are thinner and wouldn't last long in an ultra sonic cleaner. As well as the difficulty of finding and buying distilled water which those units require.

This Novelens case is only allowing what is on the surface of the lenses to be rinsed off, the same as rinsing in the hand would do. What the case is lacking is the gentle rubbing motion that gives the lenses a better cleaning.

As far as I can see, it is just a novelty gimmick that wouldn't clean the lenses as well as doing it in the palm of your hand and rinsing.

Without the gentle rubbing of the lenses , then a rinse, they would still be sitting in their own bacteria until the solution has killed them off in that case.Just the rinse it gives won't remove it all.
