Modifying a sonic cleaner for the lab


[Sean] wrote in to tell us about this hack he did to modify a consumer sonicator for lab use. Sonication is often used in labs to aid in mixing in difficult containers or to add energy for certain events.  He’s a chemist on a budget, so he couldn’t necessarily afford a nice industrial one. Instead, he found a sonic jewelry cleaner.  The main shortcoming of the consumer level one is the fact that it can only go for 3 minute intervals. He needed up to an hour at a time. His solution was fairly simple, he closed the circuit to force it to be continually in the on position, then added a timer in the power line. He notes, that the consumer model wasn’t made to be run this long and could possibly produce enough heat to damage itself. It should not be turned on, then left alone.
