The Stir Station is a multi-function magnetic stirrer. It includes the following features

• Works efficiently with beakers from 50 mL to 1 L in size and a wide range of sizes and shapes of magnetic stirring bars; stirring capacity of 800 mL in a 1 L beaker
• Stirring speed range of 50–1250 RPM
• Stirring platform is lit with 3 white, cool LEDs
• Ring stand post is conveniently positioned and affixed to the stirrer base, 4 inches from the center of the stirring platform; ideal for use with the Vernier Drop Counter

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 DataDrop program on a TI graphing calculator or Data Pro (1.15 or newer) on a Palm OS^® handheld you can collect data and view plots of pH vs. volume, first derivative vs. volume, or second derivative vs. volume.

Specifications

Care and Maintenance

• Although 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.
• The 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.
• Under normal operating conditions, the Stir Station will run in excess of 100 hours 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.
• The 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 is wise to clean spills promptly, following the normal guidelines used in dealing with chemical spills. Many stains can be removed from the stirring platform with soap and water. Never immerse the unit or flood it with water or other liquids.
• When using the Vernier Microstirrer, it is best to position the Microstirrer slightly off center of the beaker. Rotate the Microstirrer to find the smoothest and quietest operating position.
• The stirring controls are sufficiently steady on the Stir Station that you can set the stirring at a desired speed and it will not change appreciably over several hours.
