Copley’s Type ‘B’ and ‘C’ cells feature a unique clamping system to simplify cell preparation and sample collection procedures. Cells are supplied complete with individual cell tops for both ‘closed or occluded’ operation (as per USP Model ‘A’) and ‘open’ operation (as per USP Models ‘B’ and ‘C’ respectively, maximising the versatility of the HDT 1000 and HDT-1 systems.
To accommodate ‘full thickness’ membranes or skin, a new screw-type cell closure mechanism has been developed for the skin specific cell that ensures proper contact between the sample and the receptor medium. All components of the cell are made from FDA-approved inert materials and a side sampling arm facilitates easy filling, sample withdrawal and media replacement.
Copley offers a range of three synthetic membranes: PVDF, Supor Polyethersulfone and Strat-M.
The Vacuum Deaeration Apparatus Model, VDA, from Copley is an easy-to-use and inexpensive unit designed to degas receptor medium prior to its use, ensuring that diffusion is unimpeded by the collection of gas beneath the membrane.
