 6.0 Procedure 
 
 6.1 Description 
 
 6.1.1 The wrist action shaker provides constant agitation to assist in sample
 
 preparation. A variety of glassware and containers can be affixed to the agitator
 bar. The most commonly used sample containers used are Volumetric Flasks
 
 and Erlenmeyer Flasks. Other containers can be used provided the proper
 
 attachment support is available. 
 
 6.2 —__ Limitations 
 
 6.2.1 Container size is limited by the clearance of the bar and range of motion. The
 
 agitator bar is approximately 11.25 inches above the bench top.
 
 6.2.2 Take extra caution when using large volume Volumetric Flasks (500mL, 1L,
 etc). Improper fastening or excessive weight can allow slipping of flask from the
 
 grip which could result in the shattering of the container. 
 
 6.2.3 Timer settings and stroke length settings are for reference only. Ifa specific
 
 time is required as per an SOP or monograph use a calibrated stopwatch or
 equivalent. If a specific stroke length is required adjust stroke using a calibrated
 
 micrometer. 
 
 6.3. Operation 
 
 6.3.1 Affix containers securely to the agitator bar using the appropriate sized
 
 attaching grip. 
 
 6.3.2 Adjust the stroke length bar to achieve desired agitation. 
 
 6.3.3 Turn the timer past 10 minutes and then set the approximate time as needed.
 
 6.3.4 To end the cycle early turn timer to zero position. The machine will stop
 
 automatically.
