We have developed a unique portfolio of consumables, each adapted to the different feed water quality requirements and to your various applications. To maintain your water system’s performance, it’s critical to replace your purification cartridges on time and with genuine ISO 9001-certified parts.
The Centricon® Plus-70 centrifugal filter is a disposable, single-use device designed for rapid processing of aqueous biological solutions in volumes ranging from 15 to 70 mL. It is compatible with swinging-bucket centrifuges only. The Centricon Plus-70 device can concentrate most 70 mL solutions down to 350 μL in just 25 minutes (some solutions may take slightly longer).•90% typical recovery •50X to 200X concentration •Low hold-up volume •Polypropylene housing minimizes binding •Deadstop prevents spinning to dryness •Ready to use. Nothing to assemble Applications:•Concentrating and desalting chromatography column eluates •Concentrating monoclonal antibodies •Concentrating proteins or viruses from culture supernatants •Clarifying tissue homogenates and cell lysates •Buffer exchange or diafiltration
