Use an automatic rocking plate instead of hand rocking, to increase consistency and reduce repetitive stress injuries (e.g. Double Tier Rocking Platform from VWR (40000-304) or equivalent).
The automated rocker may be used with all of the MPCs®, but only if the MPC® holds the tube flat and tight against the magnet.
When using the MPC®-6 on the rocking plate, load the MPC® with ≤3 tubes.
Rock at 1 rock per second using the automatic rocking plate.
Note: Some flat-sided tubes tend to bow and require the technician to manually hold the flat side of the tube level and tight against the magnet during rocking. Contact the tube and magnet manufacturers to resolve this problem.
