Revised USP Chapters 41 & 1251 on Balances.

General Chapters 41 "Balances" and 1251 "Weighing on an Analytical Balance" were revised in 2013.

Have you updated your balance SOP's yet?

Learn from the GWP® weighing experts of METTLER TOLEDO how these Revised USP Chapters 41 & 1251 will affect your balance quality management and applicable SOPs, especially in the framework of determining minimum weight and executing routine testing. Officially, you have an alternative, more user friendly option to determine minimum weight. In respect of routine testing, a risk-based approach is suggested to determine type and frequency of routine tests, and consistent with this approach, a recommendation to carry out a daily balance check is not included anymore.
