It has been necessary, therefore, to maintain an oxygen-free chromatographic system. To lower the costs of maintaining such a system and to improve the chromatographic properties of the PEG-type columns, we offer the oxygen-resistant BTR-CW phase type. BTR-CW is a polyethylene glycol (PEG) phase, similar to  007-CW phase, but which incorporates an anti-oxidant moiety to better withstand oxygen exposure and the resultant degradation. The BTR-CW also offers increased thermal stability and longer column lifetimes.","brand":"AFP","offers":[{"title":"Default Title","offer_id":46476678135998,"sku":"CH-100240","price":820.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/6251\/1550\/files\/CH-100240.png?v=1773106467","url":"https:\/\/shop.afplifesciences.com\/products\/ch-100240-gc-column-btr-cw-30-m-x-0-25-mm-id-0-25-um-film","provider":"AFP","version":"1.0","type":"link"}
