Superior design enhances functionality.
The StirBase consists of a motor-driven magnetic cylinder encased
in an acid-resistant PVC housing. To heat and mix 50 or 100mL
samples simultaneously, place your HotBlock onto the StirBase,
drop our special magnetic stir bars into the sample-filled digestion
vessels and turn on the StirBase. To control sample temperature,
adjust your HotBlock controller setpoint as usual. Choose the
mixing speed you prefer using the StirBase Controller. The
controller has a range of 100 settings with a maximum speed of
2150 RPM. The rugged, remote controller is provided with a 6-foot
cable. It must be operated outside the fume hood for safety.
The StirBase can also be used without the HotBlock
