Description
Viscosity standard N35 is a ROTI®Calipure calibration fluid specified at 88 cSt at 20 °C for viscosity determination and instrument verification. Stated physical data include a density range of 0,81 to 0,894 g/cm³, a flash point above 112 °C, and a boiling point from ≥218 °C to ≤800 °C, supporting controlled use in physical-property laboratories. The standard is supplied in a 500 ml glass pack, suitable for repeated calibration sequences on viscometers and related measuring systems. Laboratories select N35 when a defined kinematic viscosity reference at 20 °C is required for method checks, routine calibration, or inter-instrument comparison. This ROTI®Calipure material from Carl ROTH belongs to dedicated standards for viscosity within determination of physical properties. Clear labelling of viscosity, density window, and thermal characteristics helps operators match the fluid to instrument operating ranges and safety assessments. Use according to internal calibration protocols and the product safety information. The 500 ml glass presentation balances working volume with stable storage for analytical and industrial QC settings focused on reliable viscosity measurement.

What is this article?
Viscosity standard N35, ROTI®Calipure, 88 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.
