Phoenix Dry Heat Diffusion Cells

The Phoenix™ Diffusion Cell provides improved ease of use, high durability, and greater versatility as compared to conventional hand-blown vertical diffusion cells. Phoenix cells operate on dry heat; no water-jacketing is required, allowing construction from heavy-duty borosilicate glass held to very tight dimensional tolerances. The extract-and-replace sampling through the large diameter opening in the sampling arm accommodates standard pipette tips (~300 μL), simplifying the sampling process while reducing training and operating costs.

Powerful Mixing

Special grooves machined into the tops and sides of the mixer-inserts provide strong circulation and nearly instantaneous homogenization of cell contents. This system prevents the formation of regions of higher concentration of API under the membrane, thereby reducing test variability.​

Test Preparation

Phoenix cells are quick to set up. Dosage forms are applied to an easily accessible opening in the cell cap. No clamps are required. Bubbles are easily detected and removed simply by lifting the cell and tipping it to one side.

Chemical Compatibility

The Phoenix press-on style of cell cap is made from polyether ether ketone (PEEK), sealed with O‑rings made from Viton™ (fluoroelastomer). The Phoenix threaded style of cell cap is made from polytetrafluoroethylene (PTFE), sealed with O-rings made from either Viton or Kalrez™ (perfluoroelastomer) for higher compatibility with aggressive solvents such as THF and DMSO.

Serialized Components​

As each diffusion cell, mixer, and cell cap has its own serial number, traceability and process control are improved.​​
