FAQ
Centrifugal filter devices use spin-based membrane filtration to concentrate proteins, remove salts, and exchange buffers in one workflow. Merck Amicon Ultra, Sartorius Vivaspin, Cytiva Nanosep, and Corning Spin-X options cover multiple volumes and MWCO choices for routine lab preparation.
Match MWCO to target size and application: 3K and 10K for tighter retention, 30K to 100K for faster concentration. Merck, Sartorius, and Thermo Scientific models in this category support different sample volumes and recovery needs.
Corning Spin-X and Merck Amicon Ultra 0.5 mL devices are strong choices for low-volume samples, while Sartorius Vivaspin covers broader ranges. Choose based on sample volume, membrane material, and the protein size you need to retain.
They are used in proteomics, cell culture prep, buffer exchange, and sample cleanup before LC-MS or electrophoresis. Epredia accessories and Thermo Scientific concentrators support cytology and prep workflows, while Cytiva and Merck handle general concentration tasks.
This page groups the best-ranked, Accessibility 15 products from Merck, Sartorius, Cytiva, Corning, Epredia, and the Thermo Scientific brand, making it easier to compare MWCO, volume, and format before selecting the right centrifugal filter device.
