MicroFLUX

Overview

The MicroFLUX™ offers a novel solution to conducting small volume in situ concentration monitoring, while at the same time evaluating the absorption potential of your compound as the receiver and donor chambers are separated with a membrane. The MicroFLUX™ also allows you to control for temperature and stirring.

Applications

Pion’s MicroFLUX™ system is a convenient and powerful in vitro tool with a range of applications:

Assessing the effect different formulation vehicles have on FLUX
Assessing pre-clinical performance based on pH or food
Correlating dissolution results to in vivo absorption

Features

Time-saving

During the pharmaceutical development process, many formulation vehicles are evaluated for the enhancement of solubility. However, the effect on net FLUX may not be evaluated until there is an uptake issue in pre-clinical trial. With the MicroFLUX™ system, you can simultaneously evaluate changes in solubility with changes in FLUX before the pre-clinical phase.

Problem-solving

In attempts to characterise the transport of a drug product within the body in vitro, researchers often use a variety of media change experiments to assess alterations in solubility with pH. Historically, changes in FLUX that relate to these changes in solubility have been difficult to study. The Micro-FLUX™ system offers you a reliable way to assess these effects.
