ultrasound desintegrator/homogenisator

[Lechu]

Hi all,

Is there any sonicator for bacteria cells disruption (20-100ml of
bacteria suspension to sonicate) that might (upon exchange of the tip)
be also used for much smaler volumes, 1 ml or less. I need to buy a
sonicator for bacteria and thought of getting sth versatile, suitable
also for homogenisation of small amounts of tissue (~0,5 ml). Of caurse
highly adjustable frequency and power would be required.

Thanks in advance for any ideas.
