1. 5 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 6 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 Specifications Stirring quantity maximum mL 800 Speed range RPM 50 1250 Speed Control stepless Stirring platform material ABS plastic Diameter of stirring platform cm 10 Weight without batteries g 460 Permissible ambient temperature C 0 60 Permissible relative moisture 90 Power supply 6 volt AC adapter included or four C dry cell batteries Installation category II Warranty Vernier warrants this product to be free from defects in materials and workmanship for a period of five years from the date of shipment to the customer This warranty does not cover damage to the product caused by abuse or improper use Vernier Vernier Software amp Technology 13979 S W Millikan Way e Beaverton OR 97005 2886 Toll Free 888 837 6437 e 503 277 2299 e FAX 503 277 2440 info vernier com e www vernier com Rev 5 26 09 Logger Pro Vernier LabPro Go Link and other marks shown are our registered trademarks in the United States CBL 2 and CBL TI GRAPH LINK and TI Connect are trademarks of Texas Instruments All other marks not owned by us that appea2. Stir Station Order Code STIR The Stir Station is a multi function magnetic stirrer It includes the following features e 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 e stirring speed range of 50 1250 RPM e stirring platform is lit with 3 white cool LEDs e 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 e runs on 6 volt DC power adapter included or 4 C batteries not included NOTE This product is to be used for educational purposes only It is not appropriate for industrial medical research or commercial applications What is included with the Stir Station e Stir Station unit e stirring bar 4 cm e Vernier Microstirrer e ring stand post 46 cm e 6 volt DC power adapter e Stir Station booklet this booklet How the Stir Station Works The Stir Station uses a tachometer feedback control system thus making it easier to fine tune and maintain its stirring speed This method of speed control also allows you to remove a beaker while it is stirring without affecting the Stir Station s motor speed Three LEDs are positioned beneath the translucent stirring platform and offer efficient lighting for a wide range of beaker sizes The LEDs do not heat the stirring platform and have a lon
3. a container of liquid Using Logger Pro 3 software on a Windows or Macintosh computer 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 Helpful Tips for Using the Stir Station 1 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 2 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 3 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 4 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
