Ubbelohde viscometer for dilution series

With special big reservoir, to measure dilution seriesUbbelohde glass capillary viscometer, characteristics according to DIN 51562-1 and ISO 3105. However with big reservoir, to dilute a stock solution from 15 ml to max. 75 ml, to get dilution series. For determination of intrinsic viscosity in polymer analytics.• Filling volume: 15 … 75 ml • Overall length: ca. 290 mmnot calibrated, without calibration certificate
