GRIFOLS DG Spin - 8.2 Centrifugation Speed Qualification

DG Spin Procedure for Qualification of the Operation (OQ)
8-2
NOTE:
It is advisable regular calibration of 1 year or
that recommended by the manufacturer of the
tachometer if its calibration validity period is
lower than 1 year.
8.2 Procedure for qualification of centrifugation speed
To verify that the DG Spin centrifuge complies with the speed specifications
described in section 3.1 "Technical specifications" proceed as described below:
• Switch on the
DG Spin centrifuge to the mains and activate the Main
switch (Ref. (6), Figure 2).
• Verify that the Display (Ref. (5), Figure 1) is switched on and the timer
indicates the predefined centrifugation time.
• Open the Cover of the
DG Spin centrifuge and remove the DG Spin
Head.
• Place 24
DG Gel cards in the corresponding Card holders.
• Place the
DG Spin Head and close the Cover.
• Press
to start a centrifugation batch.
• Wait for 20 seconds to ensure stabilisation of centrifugation speed.
• Vertically hold the optical tachometer on the centrifuge Cover,
pointing the reflective mark of the
DG Spin Head shown by Ref. (1) of
Figure 10.
