Operational Limits

CAUTION: To prevent sample entering the upper part of the cell and contaminating the
bearings, the cell should not be used above the limits given below. Exceeding these limits
may also cause mechanical damage to the cell.
• Maximum Angular Velocity:
• Maximum Sample Viscosity:
• Maximum Frequency:
NOTE: The quality of data obtained using the pressure cell cannot be expected to match that
obtained when conventional measuring systems are used with the rheometer. Some of the
normal calibration routines are not relevant to, or cannot be used with the Pressure Cell.
Alternative calibration routines are described in this chapter.

The geometry should not be forced into the sample. Light hand pressure
should be all that is required.
