Care and Maintenance
lAlthough the ring stand post is firmly seated in a metal-reinforced, threaded
collar, do not lift the Stir Station by the ring stand post to move it.
lThe Stir Station is a mechanical device with many moving parts. It is best to
turn off the Stir Station motor and the LED lights when the device is not in
use.
lUnder normal operating conditions, the Stir Station will run in excess of
100hours on battery power, without the lights. When you use the Stir Station
with batteries, as the batteries run down you may notice the lights dimming.
The stirring motor will continue to run but the maximum stirring speed may be
compromised.
lThe stirring platform of the Stir Station is made of ABS plastic. ABS, or
acrylonitrile butadiene styrene, was selected because of its strength, rigidity,
and toughness. It has good chemical and stress-cracking resistance. Even so, it

Using the Product
The Stir Station’s ring-stand post makes it a perfect complement to the Vernier
Drop Counter (shown here) as your students conduct titration experiments. Simply
connect the Drop Counter to the ring stand post and position a buret clamp and
reagent reservoir to deliver the titrant dropwise to a container of liquid. Using
