Products
Dissolution testers for USP Apparatus 1, 2, 5 and 6 (multi‑vessel configurations)
Manual and automated multi‑vessel dissolution testers (8–18 positions) supporting basket, paddle, paddle-over-disk, and rotating cylinder methods with method storage and programmable pH changes.
Reciprocating cylinder (USP Apparatus 3 and 7) systems
Automated reciprocating cylinder release-rate systems including sample holders and automated sampling controllers for USP Apparatus 3 and 7 applications.
Flow‑through (USP Apparatus 4) systems
Flow-through cell systems for suspension and flow-through dissolution testing and continuous sampling workflows.
Automated dissolution online analysis systems (UV/HPLC integration)
Modular automated systems providing sampling, replacement, dilution, UV or HPLC injection, online reading, data analysis and report generation for unattended dissolution testing.
Permeation systems (online and offline)
Systems for measuring intestinal and biomimetic-membrane permeability including flow-through flux cells and side-by-side small volume flux cells for permeability screening.
Transdermal diffusion flow‑through cell systems and dry‑heated transdermal cells
Flow-through diffusion cells and dry‑heated transdermal cells for topical and transdermal delivery testing across biomimetic membranes or skin samples.
