What’s the difference between the SC-100A and the SC-100?

The SC-100A is simply a new body style using the components found in the SC-200 and SC-300. It functions exactly the same, with only the audible buzzer slightly different in its tone. The reagent kits for the SC-100 and SC-100A are the same. While we no longer sell the SC-100, we still support it, and will continue to do so.
