I will present at the 67th Rheology Discussion Meeting.

The measurement of low viscosity substances can be done with high precision. Additionally, by using patented bearing technology, it achieves compactness and low cost. Clean air management is also unnecessary.

This is a rheometer suitable for rheological measurements of low-viscosity liquids, employing a double cylindrical method with an outer cylinder rotation (capable of measuring viscosity and elasticity). The torque measurement section features a practical elastic hinge bearing developed by AIST, achieving high-sensitivity torque measurement without using air bearings. This eliminates the need for clean air management, allowing for more flexible installation locations. It also contributes to CO2 reduction. Additionally, it is easy to maintain and offers advantages in size and cost. New measurement method: Dynamic viscoelastic measurements can be performed under steady flow conditions. Please give it a try. 【Features】 - Outer cylinder rotation, inner cylinder detection method with a separated drive and detection axis (strain-controlled type) - Easy sampling due to the upper support method for inner and outer cylinders - The standard glass outer cylinder allows observation of the sample's condition from the outside during measurement - The standard sample volume is relatively small, around 4ml (minimum approximately 2.5ml) - Various measurements, including dynamic measurements, can be easily performed *For more details, please download the materials or contact us.

Ideal for measuring the friction coefficient of filaments, hair, and more! A measurement device that can be easily and reproducibly used.

The friction coefficient meter "NRF Series" is a device for measuring the friction coefficient when filaments, tapes, hair, etc., come into friction with other materials, as well as for measuring the temporal changes in the friction coefficient due to the wear of the sample or the material being rubbed. It allows for variable friction speeds and sample tension, and measurements can be taken by changing the material being rubbed as needed. The measurement of the friction coefficient of filaments, fibers, hair, etc., can be easily and reproducibly performed by anyone. The measurement is simply done by applying the sample and rotating the pulley at a specified speed. 【Features】 ○ For samples with scales, such as hair, it can measure the friction coefficient when the friction direction (rotation direction) is changed. ○ The effect of lubricants and other factors on friction or wear can be measured. ○ Wear tests can be conducted. ○ The influence of the material and processing precision of pulleys, etc., on the same sample can be understood. ○ The force applied to the pulley shaft can be measured. *For more details, please feel free to contact us.

Viscosity and yield value measurement is possible! Axial type viscometer for printing inks.

The "L-A type viscometer (compliant with JIS K5701-1-2000)" is a so-called axial type viscometer with a shaft that moves in the length direction and has a concentric cylindrical shape. It can measure viscosity and yield value, which are important parameters for quality control of high-viscosity substances such as printing inks and varnishes. Shear rate and shear stress can be easily expressed through calculations. 【Features】 ○ Very easy to operate ○ The sample is placed in the gap between a temperature-controlled ring and a rod with applied load ○ Viscosity and yield value can be measured by measuring the descent time over a specified distance *For more details, please feel free to contact us.

Ideal for measuring the viscosity and flow of non-Newtonian fluids! Cone-plate viscometer.

The "NRM-200 Series" is a rotational viscometer with a cone plate (standard) configuration. The measured data can be subjected to theoretical analysis, making it suitable for viscosity and flow measurements of non-Newtonian liquids. Additionally, it allows for stable viscosity measurements at high shear rates, enabling flow measurements that correspond to actual working conditions in coating, spraying, and printing. 【Features】 - The shear rate can be measured consistently at any part of the sample, allowing for theoretical calculations of the measurement data. - Shear rates of up to 18,000 s⁻¹ can be achieved (when using 1,000 RPM). - The measurement sample volume is less than 1 mℓ. - The gap between the cone and plate is set using an electrical sensing method and a micro-adjustment mechanism. - The sample history prior to measurement can be controlled programmatically. *For more details, please feel free to contact us.*
