An upper compartment containing sample is separated from the lower compartment by a semipermeable membrane with an appropriate MWCO value chosen to exclude molecules of interest. Centrifugation is applied to force solvent through the membrane, leaving a more concentrated sample in the upper chamber. The Vivaspin column design permits protocols for one-step biomolecule concentration, rapid sample recovery (reverse spin protocol), desalting, and buffer exchange.\u003c\/p\u003e","brand":"Pall","offers":[{"title":"Default Title","offer_id":53660018213155,"sku":"PALL28932245","price":290.5,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/5896\/9012\/files\/Vivaspin_4d64b992-28f9-4b29-ac7f-777175e11fc7.jpg?v=1784163067","url":"https:\/\/onelab.co.nz\/products\/vivaspin-2-5-kda-mwco-pes","provider":"Onelab","version":"1.0","type":"link"}
