We are the market leaders in automated pKa, logP/D and solubility measurement.

At Sirius Analytical we design and manufacture highly automated instruments to measure physicochemical parameters - pKa, logP & logD, solubility and dissolution. We also operate as a CRO providing a wide range of physical chemistry analytical services.

Formulation & Development

We support Formulation and Development activities through custom designed assays. These are planned through discussion with the customer and may relate to a number of different application areas, such as understanding solubility and dissolution characteristics in different buffer systems, including biorelevant buffers.

We also have extensive experience in evaluating the effects of excipients on solubility, supersaturation, and dissolution. Our assays can also provide valuable insights into the classification of your compound in the Biopharmaceutical Classification System.
