Application Report PNR 12: Consistency of Vaselinum Album and Flavum - Hollow Cone Method (EU Pharmacopeia)

The penetrometer PNR 12 is suitable for consistency measurements required in the pharmaceutical industry. Various test kits are available for different pharmaceutical products and standards like the official WHO method European Pharmacopoeia 2.9.9.

This application report gives an example on how to measure vaselinum with Anton Paar’s penetrometer PNR 12.

The PNR 12 measures the resistance a material provides against being pierced by a specifically shaped test body. Therefore, a needle-shaped or conical test body is precisely lowered to the surface of the material under test. It will sink into the sample by its own weight for a fixed period of time. This allows a rating of the plasticity or consistency.
