CONOSTAN® certified mineral oil viscosity standards are designed for the calibration and verification of all types of viscometers, including glass capillary viscometers, rotational viscometers, cup and falling ball viscometers.
All standards are traceable to NIST and manufactured in accordance with an ISO 17034 accredited quality management system. Each standard carries a stability guarantee of up to 2 years. If you require a viscosity that we do not routinely offer, custom viscosities can be prepared to meet your needs.
