    \n\n

    Bu durum bir\u00e7ok ki\u015finin yan\u0131lmas\u0131na neden olur. FDA 21 CFR 177.1550 (perflorokarbonlar i\u00e7in) bir malzeme form\u00fclasyonu<\/em> standard\u0131d\u0131r. Temel olarak, plasti\u011fi \u00fcretmek i\u00e7in kullan\u0131lan bile\u015fenlerin g\u0131da ve ila\u00e7 temas\u0131 i\u00e7in g\u00fcvenli kabul edildi\u011fi anlam\u0131na gelir. USP Class VI ise bir biyolojik reaktivite<\/em> standartt\u0131r. Bu, bitmi\u015f malzemenin fiilen al\u0131nmas\u0131n\u0131, canl\u0131 dokuya (genellikle fareler veya tav\u015fanlar) nakledilmesini ve toksik bir reaksiyona neden olmad\u0131\u011f\u0131n\u0131n do\u011frulanmas\u0131n\u0131 i\u00e7erir. Kritik biyofarma hatlar\u0131 i\u00e7in contalar\u0131n\u0131z USP Class VI testinden ge\u00e7melidir. Tek ba\u015f\u0131na FDA uyumlulu\u011fu, s\u0131z\u0131nt\u0131 maddelere kar\u015f\u0131 g\u00fcvenli\u011fi garanti etmek i\u00e7in yeterli de\u011fildir.<\/p>\n\n<\/div>\n<\/div>\n

    \n\n

    Kesinlikle hay\u0131r. Daha \u00f6nce de belirtti\u011fim gibi, EPDM gibi elastomerler hafif\u00e7e e\u011fri bir boru ba\u011flant\u0131s\u0131na uyum sa\u011flamak i\u00e7in esneyebilir ve deforme olabilir. PTFE ise rijittir. Y\u00fcks\u00fckleriniz birka\u00e7 milimetre bile kaym\u0131\u015f olsa, sert PTFE y\u00fczey \u00e7eli\u011fe tam olarak oturmayacak ve s\u0131zd\u0131rmazl\u0131k eleman\u0131ndan s\u0131v\u0131 ge\u00e7i\u015fi ya\u015fanacakt\u0131r.

Y\u00fcks\u00fcklerin hafif\u00e7e a\u015f\u0131nm\u0131\u015f veya \u00e7ukurla\u015fm\u0131\u015f olabilece\u011fi eski ekipmanlar i\u00e7in m\u00fckemmeldirler \u00e7\u00fcnk\u00fc sert plastiklere g\u00f6re daha kolay s\u0131zd\u0131rmazl\u0131k sa\u011flarlar. Ancak, en y\u00fcksek safl\u0131ktaki hatlar i\u00e7in kat\u0131 modifiye PTFE tercih edilir; \u00e7\u00fcnk\u00fc zarf\u0131n \u00e7izilmesi veya hasar g\u00f6rmesi durumunda elastomer \u00e7ekirde\u011fin s\u0131zma riski yoktur.<\/p>\n\n<\/div>\n<\/div>\n
