Marshall,  I am using a unit very similar to the one you have here in 
the Ebay link. Bought mine off Ebay in Australia,  and it works just 
fine. Paid 26 dollars Australian which is probably around 21 dollars American.


Not claiming that my results are totally perfect as I have nothing to 
compare them with but going by the descriptions I have read in the 
emails here on the list,  the results are fine and doesn't need an 
expensive unit.

most cases, rise somewhat with the passage of time (especially in 
cases of uninterrupted operation). This should not be of great 
concern to the experimenterIF there is always sufficient volume 
of liquid in the tank. MOST ultrasonic cleaners (even the cheaper 
ones) have fill marks on the sides...one for Minimum and one for 
Maximum. For obtaining the most acceptable results in MOST 
operations such as the one I outlined for the Encapsulation 
experimentit is advisable to fill the tank to at least the 2/3 
level...but ABSOLUTELY
WELL ABOVE MINIMUM. There is little danger of overheating the 
vitamin C to a point of compromise.but THERE IS some danger of 
damaging Barium Titanate or Electromagnetic
type transducers (especially the cheaper ones)...and the Harbor 
Freight unit IS one of the cheaper ones. Actually, the general 
likelihood of damaging, even the Barium Titanate transducers would 
only occur in cases where the experimenter heated the liquid 
before starting the US unit.
Because of the additional, useful, features on the larger (2.5 
liter) ultrasonic
cleaner available at Harbor Freight (Item #95563)it should be a 
better buy ($60.00)for persons desiring to make larger quantities 
of encapsulation candidates. However, the smaller unit should be 
quite adequate for the individual experimenter.

Sincerely, Brooks Bradley.

Main concern would be overheating the transducer and destroying it.



Time your work with a kitchen timer thingy that will chime.

Is there any reason why an ultrasonic cloth washer cannot be used for  
lyposomal encapsulation ? BTW it would not heat the water itself,  
though the transducer evidently can function in hot water.
