The Good
Compact and affordable unit ideal for basic cell disruption.
The Bad
Adjustable amplitude but no quantitative way to monitor energy delivered to sample
The Bottom Line
This basic unit is devoid of bells or whistles: no programming, no energy output display, no temperature monitoring, etc. It does have a handy thumb switch, it is compact and affordable, and it does work well for physical disruption of cells in the sub-mL to mL volume range.
