Mechanical Qualification Testing MQT

Labserv provide mechanical qualification (MQT) for Apparatus 1 and 2 as described in USP General Chapter <711>.In most cases, Mechanical qualification is performed prior to PVT. Rigorous mechanical alignments and adjustments are regularly required to aid a PVT pass;

Our MQT provides 100% evaluation of the following in accordance with <711>:
Vessel & Shaft Centering
Wobble for Basket Shafts, Baskets, and Paddles
Basket/Paddle Height
Vessel Verticality
Shaft Verticality
Motor Speed
Vessel Temperature
Dimensions for Paddles, Baskets, Basket Shafts, and Vessels

Requirements include certified tools • Digital level • Validation tool kit • Vibration meter • Tachometer • Thermometer • All NIST traceable and a USP trained operator

A mechanically-compliant instrument may still not pass the PVT, but Labserv expertise in mechanical calibration procedure can certainly minimize variation within App 1 and 2.

Performance Verification Testing PVT

The USP chemical test (PVT) is also a test of the entire procedure, including the operator, the instrumentation and the “reference standard” tablets. Many variables effect PVT results, not just the apparatus, and PVT failures can be common. Find out more here >>
