Diffusion Cap Kits

In diffusion cell testing, the active pharmaceutical ingredient (API) passes from the dosage chamber into the receptor medium in an amount proportional to the exposed area of the membrane, as determined by the orifice diameter. Phoenix cell cap kits are designed to provide analysts with precise control over this critical factor. In each cell cap kit, the orifices of the dosage chamber above the membrane and the cell cap below the membrane are machined to tight tolerances for diameter and concentricity.

Press-on-Cap Kits – Skin Applications

The small cell for skin applications is designed to accommodate testing with smaller membranes (16 mm as opposed to 25 mm diameter). In all cases, the 7 mm deep dosage chamber allows skin or synthetic membranes up to 3.0 mm thick.
