Viscosity & Flow Measurement
-
Viscosity is perceived as ‘thickness’ or resistance to pouring, but there is more to viscosity than this. All fluids have an internal friction between molecules, which determines how well fluid flows. Due to this internal friction, energy is required to move the liquid and viscosity is the measure of the resistance to flow. Elcometer manufactures and supplies a wide range of viscosity gauges from flow cups to dip cups to rotational viscometers.

Thermosel System
-
The difficulty with viscosity measurements of hot melts and liquids at elevated temperatures has been in maintaining accurate temperature control that is consistent from sample to sample so that meaningful data could be obtained. The Brookfield Thermosel solves this problem by providing a stable, precisely controlled sample environment. This, together with the inherent accuracy of the Brookfield Viscometers, is fundamental to the Thermosel System, which produces viscosity measurements that are not only accurate but entirely reproducible.

Rheometers
-
The MCR rheometer series from the market leader offers you one thing first and foremost: an open range of possibilities. Whatever your rheological requirements are and will be in the future – based on its modular setup, your MCR rheometer is efficiently and comfortably adapted and extended to meet your needs, from routine quality control to high-end R&D applications. An investment in an MCR rheometer is always a safe investment in longstanding technology: The air-bearing-supported EC motor, for example, was developed by Anton Paar and has been used in all MCR models for over 25 years to ensure accuracy across a vast viscosity range. It makes it possible to measure liquids with a viscosity even lower than water and also characterize stiff materials like polymer composites or steel by DMA – and everything in-between.

High Performance UV Nanoimprint Resist
AMONIL®
-
UV Nanoimprint is a mechanical molding technique. A template made from quartz or a flexible elastomer with a 3D relief is brought into intimate contact with a UV-curable resist spin-coated on top of a substrate. Applying low imprint pressure at room temperature features are filled within seconds due to the low viscosity of the imprint resist. The resist is hardened via UV-light through the backside of the template. Finally substrate and template are separated. The replicated resist relief can further be transferred into the substrate via RIE-process or used as functional element.

Physical Test Equipment
-
When assessing a coating for suitability for a particular application the testing of the physical properties such as bendability, impact resistance, hardness, washability and abrasion resistance are all required to provide information for decision making. Testing of the pigments using fineness of grind gauges, determining the specific gravity of the coating using density cups, measuring the viscosity using viscosity cups or rotational viscometers and assessing the drying time all provide information for the coating technical data sheets.

Viscosity-Rotational
-
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal notion of "thickness". A liquid whose viscosity is less than that of water is sometimes known as a mobile liquid, while a substance with a viscosity substantially greater than water is called a viscous liquid.

Viscometers
-
GAOTek proudly presents a wide range of viscometers. A viscometer is used to measure the viscosity of a fluid or liquid under a certain flow conditions. Thus, viscometers only measure under one flow condition. Different types of viscometers have either the fluid stationary which allow object to pass through or vice versa. Therefore, these devices measure the drag caused by the interaction between the fluid and object surface.

Viscometers
-
A viscometer, viscosity meter or rheometer is a measuring instrument used to determine a fluid's internal flow resistance or viscosity. The term viscosity typically refers to shear viscosity, i.e., how a material reacts to being sheared. Rotational viscometers with rotating spindles or rotors, also known as "cup and bob" or Searle viscometers, are the most common tools used to measure the shear viscosity of fluids. However, a fluid's viscosity also may be measured on the basis of stretching. The technical term to refer to this is extensional viscosity.A viscometer is frequently used in laboratories, but it also has practical applications in factories and other industrial environments. A viscometer can be an important component in process and quality control. Companies can save money by placing a viscometer in a production line and making fluid viscosity measurements in real time.PCE Instruments offers a variety of handheld, portable, benchtop and in-process, real-time viscometer products that measure the absolute / dynamic (shear) and kinematic viscosity of fluids. Handheld or portable viscosity meter devices allow users to take simple, single-point measurements in the field and in the lab. Benchtop or stationary viscometer devices are complex rheological measuring systems that allow for a more detailed examination of liquid samples.

THW-L2
-
Designed with speed and operational simplicity in mind, the Transient Hot Wire (THW-L2) Liquid Thermal Conductivity Meter is an advanced measurement system for direct determination of the thermal conductivity of liquids and pastes in accordance with ASTM D7896-19. In less than 2 seconds, a single measurement of small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity. Using a non-stationary measurement approach, the THW-L2 uses rapid test times to limit convective effects for samples with a wide range of viscosities. The THW sensor consists of a 60 mm heating wire that is fully inserted into an isothermal sample. A constant current source (q) is used to heat the sensor wire and the temperature rise is recorded by monitoring the change in electrical resistance of the wire. The slope (m) is determined from the plot of temperature rise vs. logarithm of time and is used in the calculation of thermal conductivity (λ). Liquid samples of high thermal conductivity will have a lower slope, while liquid samples with low thermal conductivity will have a higher slope.

Textile Tester
USTER TESTER 6-C800
-
The USTER TESTER 6-C800 is ready for the most demanding technical textiles applications. The amazing diversity of technical textiles applications is matched by the wide variety of quality characteristics needed in the raw material used so filament yarn producers know they must work to the most stringent specifications and standards. Quality failings, especially in the critical parameter of yarn evenness, can be expensive, but the USTER TESTER 6-C800 provides fast, accurate testing to the tightest tolerances, protecting filament producers against customer complaints and claims. Raw materials for technical textiles cover a wide range of end-uses and performance requirements. Viscose fibers, for instance, are found in lightweight blouses as well as in wire cording and high-speed car tires. Polyester, common in low-price clothing, is also transformed in special high-tech versions, for sophisticated sportswear and outdoor clothing. Countless other examples of technical applications for filament yarns span sectors such as medical, industrial, transport, engineering and protective clothing. Despite this variety of products, there is one fundamental requirement which is common to all: the absolute need for yarn evenness, measured to close tolerances, to ensure that the functional and aesthetic properties of the finished article achieve the high quality standards that customers demand.
