Rotating external agitator rpm values from 15 rpm to 90 rpm  Q4  Item 1.2  Clause 1.2.4 Scrapers material shall be made from chemically coated  polytetrafluoroetilen (PTFE).  Scrapers made of POMc have better creep resistance and dimensional stability,  lower coefficient of friction and moisture-absorption characteristic. While working  with such products as emulsions and semisolids in pharmaceutical, cosmetics, skin  care products and chemical industries are more advantageous then the PTFEs  temperature and chemical resistance.  Will the vacuum mixer with Scrapers made of POMc be considered satisfying the  terms of reference?  Please refer to Changes No:1 to the Tender Dossier, article 1.2.4.  Q5  Item 1.3 Ultrapure Water System  1.3.5 For feed water Total Organic Carbon (TOC) between 1500-2000ppb,  product water Total Organic Carbon (TOC) shall be maximum 5ppb (parts per  billion).  The manufacturers, showing this value in their catalog, made the measurement in  1000 ppb feed water. Wgen proceeding with the correct proportion, the device we  want to offer meets the requested specification. To avoid any misunderstanding  during the tender evaluation phase, we kindly request from Contracting Authority  change this specification as below: 1.3.5 For feed water Total Organic Carbon (TOC) between 1000 ppb, product  water Total Organic Carbon (TOC) shall be maximum 2 ppb (parts per  Please refer to Changes No:1 to the Tender Dossier, article 1.3.5.
