Understand the effect of humidity and moisture content

Humidity affects the compressibility of key pharmaceutical ingredients (e.g. microcrystalline cellulose). As such, formulation and manufacturing professionals need to understand the impact of humidity on formulations. In addition, products requiring low humidity or an inert atmosphere for stability (effervescent, oxygen or moisture sensitive materials) must be studied under actual manufacturing conditions. The Gamlen CHE allows tablets to be both made and tested in a controlled humidity environment.

Using the Gamlen CHE, you can dry granulate, mill, compact and pack tablets all under low humidity and without risk to your moisture sensitive materials. It facilitates quick and easy GMP manufacture of small tablet batches. The Gamlen CHE is also ideal for material characterisation, pre-formulation, formulation and process development, QbD for tablets and QC of incoming APIs and excipients. Tablets made in the Gamlen CHE can easily be transferred to closed containers or used for long term stability testing.
