Viskozimetr Lovis 2000 M/ME pracuje na principu padající kuličky dle Höpplera a měření času potřebného k překonání dané vzdálenosti v průsvitných i neprůsvitných kapalinách. Tento přístroj se používá především k měření viskozity nízkoviskózních kapalin pro aplikace v oblasti výzkumu a vývoje, farmaceutického a chemického průmyslu. Měřením s přístrojem Lovis 2000 M/ME lze získat hodnoty dynamické viskozity, vnitřní viskozity, molekulové hmotnosti polymerů a mnoho dalších.

Key features

Pro výzkum a vývoj

  • Malé množství vzorku (počínaje 100 µl)
  • Opětovné získání vzorku
  • Široký rozsah teplot (-30 °C až 100 °C; -22 °F až 212 °F)
  • Široký rozsah viskozit (0,3 mPa.s až 10 000 mPa.s)
  • Nejvyšší přesnost
  • Možnost různého sklonu kapiláry při testování tokových vlastností ne-newtonských kapalin

Pro farmaceutické a medicínské laboratoře

  • Uveden v americkém lékopisu
  • Farmaceutický kvalifikační balíček
  • Volitelná kombinace s ostatními přístroji Anton Paar pro měření hustoty, indexu lomu, zákalu a pH
  • Průtočný systém ke zvýšení kapacity

Pro chemický průmysl

  • Hermeticky uzavřený systém pro těkavé nebo toxické vzorky
  • Vysoká chemická odolnost (borosilikátové sklo nebo PCTFE)
  • Speciální funkce pro měření polymerů a vyhodnocování výsledků
  • Automatické plnění za použití autosampleru
  • Testovaní neprůhledných vzorků
