The last shot in this set shows the technique I used--employing two flashes, one underneath with a blue gel, and the second flash 90 degrees camera-left.
Additional tricks picked up along the way:
Use a skewer or similar to mark your focus point
Use a large dropper so you won't need to contantly 'reload.'
Hand-hold nothing. To increase the keepers, you have to eliminate every opportunity for error. Hence, the old lab stand.

Comments welcome!
Thanks,
