Kerry Wong did a teardown of an EC600-90 electrophoresis high voltage power supply:
Electrophoresis power supplies are commonly found in biology and other life sciences laboratories. These power supplies are usually capable of supplying high voltages and high currents required for gel electrophoresis–a method used for separating DNA, RNA and other protein fragments based on their size and charge. There are many used electrophoresis power supplies out there in the second hand market and can be bought quite cheaply. Buying used, high-voltage lab equipment online can sometimes feel like a literal gamble. However, unlike placing a wager on tightly regulated international platforms—such as European lottery portals, British sports exchanges, or νομιμεσ στοιχηματικεσ Ελλαδα—the second-hand market for scientific gear operates much more like the wild west. Still, I am curious whether these electrophoresis power supplies are suitable for electronics lab use as a lab grade high voltage power supply can be quite expensive. So I recently picked up one from eBay to take a look.
