The Vacuum De-aeration Apparatus from Copley Scientific is used in semisolid pharmaceutical testing for de-gassing the medium used in vertical diffusion cells (VDCs) to measure the drug release profile of semisolid products.

The Vacuum De-aeration Apparatus from Copley Scientific is used in semisolid pharmaceutical testing for de-gassing the medium used in vertical diffusion cells (VDCs) to measure the drug release profile of semisolid products. The apparatus is designed to provide a source of prewarmed, de-gassed media for use in VDCs. 

It operates by heating the receptor media up to 45 °C under vacuum conditions of 90 kPa below atmospheric pressure. Performance data suggest that dissolved oxygen can typically be reduced to below 4 ppm within one hour.
