{"product_id":"polysucrose-400-1-x-20-kg","title":"Polysucrose 400, 1 x 20 kg","description":"\u003cp class=\"richp\"\u003ePolysucrose 400 is a synthetic high molecular weight polymer made by the copolymerization of sucrose and epichlorohydrin. The molecules have a branched structure with a high content of hydroxyl groups giving a good solubility in aqueous solutions.\u003c\/p\u003e\u003cp class=\"richp\"\u003eThe reactivity and stability of Polysucrose 400 are determined by its hydroxyl groups and the glycosidic bonds in the sucrose residues. Polysucrose is stable in alkaline and neutral solutions. At pH values lower than 3, it is rapidly hydrolysed, especially at elevated temperatures. In neutral solutions, Polysucrose 400 can be sterilized by autoclaving at 100°C for 30 minutes without any degradation.\u003c\/p\u003e\u003cp class=\"richp\" sugg=\"true\"\u003ePolysucrose 400 is readily soluble in aqueous solutions when added slowly to the liquid with constant stirring. Concentrations up to 50% (w\/v) can easily be obtained.\u003c\/p\u003e\u003cp class=\"richp\" sugg=\"true\"\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAbsorption \u0026lt; 0.45 \u003c\/li\u003e\n\u003cli\u003eSpecific optical rotation (α)D20 53° – 59° \u003c\/li\u003e\n\u003cli\u003eIntrinsic viscosity (20 °C) 0.14 – 0.20 \u003c\/li\u003e\n\u003cli\u003eAverage molecular weight (Mw) 450,000 ± 100,000 g\/mol \u003c\/li\u003e\n\u003cli\u003eMw distribution by GPC conforms to standard \u003c\/li\u003e\n\u003cli\u003eLoss on drying (%) \u0026lt; 5.0 % \u003c\/li\u003e\n\u003cli\u003epH (10 % w\/v aqueous solution) 7.0 – 9.0 \u003c\/li\u003e\n\u003cli\u003eSulphated ash \u0026lt; 0.3 % \u003c\/li\u003e\n\u003cli\u003eContent of chloride (ppm) \u0026lt; 500 ppm \u003c\/li\u003e\n\u003cli\u003eSterilization test Conform \u003c\/li\u003e\n\u003cli\u003eMicrobiological contamination \u0026lt; 100 CFU\/g \u0026lt;10 yeasts and mould\/g \u003c\/li\u003e\n\u003cli\u003eBacterial endotoxins \u0026lt; 10.0 IU\/g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Serumwerk Bernburg AG","offers":[{"title":"Default Title","offer_id":54931611124003,"sku":"SW7828","price":0.01,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0926\/3870\/8003\/files\/Serumwerk_20logo_20800x800_20100dpi.png?v=1776281445","url":"https:\/\/chromspec.com\/products\/polysucrose-400-1-x-20-kg","provider":"Chromatographic Specialties Inc.","version":"1.0","type":"link"}
