Product Overview
Wheaton's Biostir 4 runs four stirring positions from one drive cabinet. The top is marked with four target circles, one per vessel, and a single speed setting knob on the front sets them together, with a red pilot lamp beside it. There is no heater control on the panel; this is a stirring-only unit.

Frequently Asked Questions
Does it heat?
No. There is no heater control; it stirs only.
Can each position run at its own speed?
No. One knob sets the speed for all four positions.
Are manuals included?
Not included.
Why this instead of four single stirrers?
One cord, one footprint and one knob for four vessels. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
Four flasks, one knob, one outlet. If the experiment calls for replicates, the bench just got shorter.
