Description
Viscosity standard S20 is a ROTI®Calipure calibration liquid specified at 43 cSt at 20 °C for reliable viscosity determination in the laboratory. Supplied in a 500 ml glass pack, it supports routine verification and calibration of viscometers and related instruments used in physical-property testing. Density is stated in the range 0,81 to 0,894 g/cm³, with a flash point above 112 °C and a boiling range from at least 218 °C up to 800 °C, giving operators clear handling context during standard work. The product belongs to the viscosity standards portfolio from manufacturer Carl ROTH and is intended for applications focused on determination of physical properties. Laboratories engaged in quality control, method validation, or instrument qualification can use this S20 grade to maintain traceable measurement conditions. The defined viscosity value at 20 °C and the glass packaging format make it a practical choice for bench-scale calibration routines where consistent reference material is required.
This article is part of Viscometers, in Density & viscosity measurement.

What is this article?
Viscosity standard S20, ROTI®Calipure, 43 cSt (20 °C), 500 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Viscometers, inside Density & viscosity measurement, in Lab instruments.
A capillary viscometer times the flow of a liquid through a tube. A rotational viscometer twists a spindle in the liquid. Both need a stated temperature. Kinematic and dynamic viscosity are different numbers. The capillary size has to put the flow time in the range the method allows.
Density is mass divided by volume. A hydrometer floats at a depth that depends on the density of the liquid. A pycnometer is a vessel of known volume that is weighed full. Viscosity is the resistance to flow. A capillary viscometer times how long a volume takes to fall through a tube. Both measurements need a stated temperature, because liquids change density and viscosity as they warm. The units trace to the BIPM and to NIST.
