Coating Rheometer Reports: Record Geometry and Gap

The key distinction

Geometry selection and the measurement gap are part of rheometer setup. Their suitability depends on the sample and method, so laboratory records should preserve the configuration rather than reporting only a final viscosity value.

Practical checks

1. Ask for the approved method identifier and setup record.
2. Check whether compared reports used equivalent configurations.
3. Refer unexplained differences to the laboratory before combining the data.

Example

Illustrative example: two formulation reports appear different, but one lists a different geometry. The reviewer flags the setup difference and asks whether a controlled comparison is needed.

Scope and limits

This is a documentation checklist, not an instruction to choose a particular gap or geometry. Equipment guidance, sample characteristics and the validated method must determine the actual setup used.
