[1] The HT 24 can run for 90 seconds continuously, but can cycle 10 times using the pulsing feature. When pulsing, a pause is inserted between the run times, and the pause is between 1and 120 seconds. Thus, total processing time can be up to 15 minutes with pauses of as little as 1 second.

[2] Initially the GenoGrinder 2010 could be adapted to hold four deep well plates. The clamp assembly was later modified to hold up to six plates.
