Master Regulatory Requirements for Balances Used in Pharmaceutical Analysis

Modern Requirements for Laboratory Balances: A Global Pharmacopoeial Perspective

Global regulatory standards for laboratory balances are evolving rapidly, with major updates across key pharmacopoeias including the USP (07/2025), Ph. Eur. (07/2021, under revision), JP (06/2024), and ChP (03/2025).

Overview:

In this webinar, experts present a clear and comprehensive overview of the latest changes , focusing on calibration, performance verification, traceability, minimum weight determination, and the implementation of safety factors. They will walk you through how to implement calibration, performance verification, traceability, minimum weight determination, and safety factors according to current regulations.

Watch the webinar to ensure your laboratory remains compliant, efficient, and aligned with the evolving global standards for balances in pharmaceutical quality control.

Sneak Peek: What You'll Learn in This Webinar

Does USP <41> give any guidance on how often we should perform performance checks or qualification?

USP <41> follows a risk-based approach without fixed frequencies for performance checks or qualifications. Users define intervals based on application risk, historical data, and quality systems.

Is the revised USP <41> only for analytical balances in the lab?

No, revised USP <41> applies to all balances used for quantitative weighing in labs, not limited to analytical balances.

Am I still allowed to use a test weight below 100 mg for the repeatability test?

Yes, test weights below 100 mg (few % of capacity) are allowed for USP <41> repeatability; accuracy tests require 5-100% capacity weights.

Can Sartorius balances show the current minimum weight directly on the display for the operator?

Yes, Sartorius Cubis^® II balances display the current minimum sample net weight (msnw) directly in the weighing screen via USP Advanced. The system continuously calculates minimum weight (mmin), safety factor (SF), and msnw based on the latest sensitivity and accuracy test results, then automatically checks whether these values remain within the user-defined acceptance limits.

How will Sartorius update its instruments to meet the new requirements?

Sartorius Cubis^® II complies via USP Advanced software for min weight and range; Service provide updated certificates and testing for 2026 revisions.

What exactly does it mean to follow ALCOA+ principles?

ALCOA+ means Attributable, Legible, Contemporaneous, Original, Accurate data, plus Complete, Consistent, Enduring, and Available for integrity in pharma records.

What information is now mandatory on a balance calibration certificate to be compliant with the USP <41>?

Mandatory: operating range, calibration uncertainty (as-found/as-left), test weights used, and standards like EURAMET cg-18 for USP <41> compliance.

To learn more, register for the webinar.

How can I routinely check the lower daily working weight on my Cubis^® II balance, and how do I define an appropriate acceptance limit for this weight?

Use Cubis^® II USP Advanced for daily sensitivity testing with low test weight; acceptance limit: 2 × SD ≤ 0.05% of nominal weight.
Note: Complete accuracy test limit is ≤ 0.10%.

Is “smallest net weight” the minimum weight?

“Smallest net weight” is not the „minimum weight“,only exeption is saftyfactor = 1 (smallest net weight = minimum weight x safety factor)

To learn more, register for the webinar.

What working range and performance limits does my Cubis^® II balance have under USP <41> and USP <1251>?

Cubis^® II displays min weight, operating range (ORmin to ORmax); limits: 0.10% repeatability/accuracy per USP <41>.

To learn more, register for the webinar.

What are the key differences between USP <41>/<1251> and the European Pharmacopoeia requirements for analytical balances?

USP <41> requires 5-100% accuracy tests, min weight from repeatability; Ph. Eur. 2.1.7 uses sensitivity, as-found/as-left verification with risk-based intervals.

To learn more, register for the webinar.

What level of vibration is acceptable for analytical balances, and does the allowable vibration depend on the balance’s sensitivity or is there a general standard?

No general standard; vibration acceptability depends on balance sensitivity—verify via site repeatability/accuracy tests; use anti-vibration tables.

To learn more, register for the webinar.

Is weighing by difference valid and accurate when the tare vessel is above the minimum weight, but the net sample is at or below the minimum weight (for example, a 1 g volumetric flask used to weigh 20 mg on a balance with a 20 mg minimum weight)?

Yes, valid if net sample meets or exceeds minimum weight; USP <41> applies limit to net only, not tare vessel.

To learn more, register for the webinar.

Do pharmacopoeial guidelines expect routine performance checks to be carried out by regular laboratory users, or is it recommended that these performance checks are performed only by qualified service providers?

Guidelines expect lab users for routine repeatability checks; qualified service providers for full calibration and qualification.
