 | What is the difference between a 25K and a 30K unit? |
|
 | Some units work with a frequency of 25,000 cycles per second (or Hertz) and others work with a frequency of 30,000 cycles per second. These are referred to as 25K or 30K units. The frequency determines how fast the insert tip will vibrate. 30K inserts vibrate at a faster rate of speed than 25K units. However, if you look at the stack (the multiple pieces of magnetic material attached to the base of the insert that convert the electrical current into motion), the 30K stack is actually shorter than the 25k stack even though it is more powerful. |
