Advanced techniques for extractables testing

Extractable and leachable (E&L) testing methods, such as draft pharmacopeial chapters USP 1663 and USP 1664, demand carefully controlled extraction. Traditionally, routine extractables testing has been performed using soxhlet and reflux extraction, which have lengthy extraction times (over 24 hours), variability in manual handling, and require disposal of potentially flammable and hazardous organic solvents.

Accelerated solvent extraction is a proven technology with significant improvements over traditional extraction techniques. You can use less bench space, extract up to 10 times faster, and use less solvent.

Accelerated extraction for fast material selection studies

Automate extraction, filtration, and clean-up of compounds from solid and semisolid samples in minutes using the automated Thermo Scientific™ Dionex™ ASE™ 350 Accelerated Solvent Extractor. This system accommodates sample sizes of 1-100g, allows unattended extraction of up to 24 samples, and uses 50-90% less solvent compared to other methods. The chemically inert pathway supports acid and alkaline sample matrices and solvents. Flexible, easy-to-operate, cost-effective, and operated under compliant software, the Dionex ASE 350 is ideally suited for high-throughput, GxP laboratories.
