The Phoenix RDS (Robotic Diffusion Station) platform offers fully automated sampling and collection for either six or twelve vertical diffusion cells, enabling automated diffusion testing. Moreover, it features a compact footprint and uses the same heating and stirring blocks from the DB-6. A third block accommodates 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, the system allows operation of up to two RDS systems (24 vertical diffusion cells at once) from a single computer workstation.
Phoenix Diffusion Cells
The Phoenix™ Diffusion Cell offers improved ease of use, high durability, and greater versatility compared to conventional hand-blown vertical diffusion cells. Operating on dry heat, Phoenix cells eliminate the need for water-jacketing, enabling construction from heavy-duty borosilicate glass with tight dimensional tolerances. Additionally, the large diameter opening in the sampling arm facilitates extract-and-replace sampling, accommodating standard pipette tips (~300 μL). This design simplifies the sampling process, reduces training requirements, and lowers operating costs.
Rapid Sampling and Collection
Automated sampling with an angled probe simulates manual methods by withdrawing and collecting samples, then replacing the media. The system meets or exceeds volumetric accuracy of ±1% or 25 μL. Furthermore, staggered sampling with pre-programmed offset times makes test preparation easier. Rapid sampling requires just two minutes per cell. Carryover prevention is excellent, typically needing only 200 μL for rinsing. Moreover, custom wash protocols allow the analyst to clean the probe with one or more solvents at once or with air.
Programming Versatility
The RDS is designed to provide a broad range of programming capabilities to the analyst, including rapid setup of diffusion test parameters; configurable instructions to operators; sampling, wash, and rinse configurable on a cell-per-cell basis; speed and temperature changes during run; ability to add media to offset evaporation; ability to run different cell groups with different settings.
Diffusion Master and 21 CFR Part 11 Compliance
Teledyne LABS Diffusion Master software provides speed, security, and scalability in an easy-to- use interface. Key features include an unlimited number of users and groups, configurable permissions, password options, inactivity timeout and a complete audit trail. In addition, it supports serial number tracking, signatures for digitized and archived test reports, logs for events, errors, and test reports, and searching and filtering on any number of database parameters. Finally, on-screen test progress and sample time alerts, along with system status and test reports output to network printer.
