Diffusion Cell Testing

Teledyne LABS Phoenix™ Dry‐Heat Systems make diffusion‐cell testing faster, easier, and more economical. The Phoenix Systemincludes an advanced diffusion cell design. Options include the compact Phoenix DB-6 six‐cell manual sampling system and the Phoenix RDS automated sampling system capable of handling up to 24 diffusion cells at once.

An important advantage of the Phoenix System is the speed with which receptor cell contents are homogenized. Visual testing with red dye placed on the surface of the media at the top of the sampling arm shows complete dispersion occurs within a few seconds.Explore the pages in this section to learn more and to configure your own system.

Six-Cell Diffusion Testing System

Phoenix DB-6 - Teledyne LABS

The Phoenix DB-6 (six-cell diffusion block) provides an ideal platform compliant with 21 CFR Part 11 for release-rate testing of six vertical diffusion cells at once using manual sampling methods. Controlled by an advanced computerized display, the DB-6 provides uniform and precise heating and stirring of six cells. The compact footprint of the DB-6 economizes on lab bench space.

Automatic Sampling Robotic Diffusion Station

Phoenix RDS - Teledyne LABS

The Phoenix RDS (Robotic Diffusion Station) platform provides fully automated sampling and collection for either six or twelve vertical diffusion cells in a compact footprint, using the same heating and stirring blocks as are found in the DB-6. A third block holds a wash station and up to five additional media sources. Samples are collected into 12×32 vials with pre-slit septa. Controlled by Teledyne LABS Diffusion Master™ software, up to two RDS systems (24 vertical diffusion cells at once) can be operated independently from a single computer workstation.

Dry Heat Diffusion Cells

Phoenix Series - Teledyne LABS

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.
