Hot Disk AB is dedicated solely to facilitating its clients’ thermal transport property measurements. Utilizing the groundbreaking and recently ISO-certified TPS (Transient Plane Source) technique, Hot Disk instruments accurately ascertain the thermal conductivity, thermal diffusivity and specific heat capacity of a vast range of materials from single transient recordings. We have claimed considerable market share from competitors employing older and more limited techniques in recent years.
Hot Disk AB develops and provides equipment for measuring and testing thermal conductivity, thermal diffusivity and specific heat capacity. With our equipment, testing thermal properties is easy, fast and non-destructive.
Knowing the thermal properties of materials or devices is crucial when designing any application where heating or cooling is a factor. Being able to readily acquire this information is important for designers, engineers and scientists alike.
Examples for Applications:
Anisotropy: Modern batteries (Li-Ion) have drastically different thermal ¬conductivities in different directions. Simple and accurate ¬measurement procedure with Hot Disk sensors. Hot Disk can perform anisotropic measurements on modern, Li-Ion batteries with a regular stack structure. The stack structure can be either cylindrical stack, or a plane stack structure.
R&D Carbon (RDC) is the world-leading supplier of know-how in the field of carbon electrodes. Our multi-disciplinary and laterally-thinking team serves the aluminum, petroleum coke, pitch and electrode industries worldwide.
Our long experience and intensive research into carbon technology provide solid support to our constant quest to improve product quality. RDC contributes substantially to reducing metal production costs and to lowering capital investment for production plants.
R&D Carbon performs basic and applied research in conjunction with leading universities which are also working on carbon. Many doctorate students from renowned universities and research institutes in New Zealand, Switzerland and China have intensively investigated several hot topics in their PhD thesis. They benefited from the first class testing facility of our research laboratories, as well as from the wide experience of our senior scientists in the carbon and metal field.
The SURAGUS GmbH develops, manufactures and sells eddy current-based testing technology for innovative testing tasks. The company uses new technological opportunities due to advances in signal processing, the availability of more powerful computing technologies and possibilities of new manufacturing and miniaturization methods. Applications are amongst others quality control of structured and unstructured functional layers, quality assurance of carbon fiber materials and classic conductive materials. The company is a spin-off and licensees of the Fraunhofer IKTS Dresden.
The eddy current method utilizes local conductivity variations of the test objects for the characterization of correlated quality characteristics such as thickness, conductivity, homogeneity and purity or physical changes. The complex eddy current signal contains various information about the test object which can be separated in many cases with simple or complex algorithms. Our eddy current testing technology is based on a powerful eddy current electronics with a frequency range from 10 kHz to 100 MHz, which is combined with different sensor concepts depending on the application.

Thermic Edge Ltd is a design and manufacturing business with specialist knowledge of every kind of laboratory heating applications, from basic elements or sample heaters, to complete hot stages with rotation, manipulation and substrate bias. We have standard ranges of stand alone sample heaters and flange mounted sample heaters with feedthroughs incorporated. Our sample heaters and hot stages are used in a very wide range of laboratory applications including, PVD sputtering, thermal deposition, e-beam, CVD, MOCVD, PLD, ion beam implanters, carbon nanotubes and graphene growth.
Thermic Edge Ltd can offer a range of sample heater controllers to accurately control any kind of hot stage or sample heater. Heater controllers are fitted with Eurotherm PID temperature controllers as standard, but we can incorporate any type of controller that our customers might specify.
Thermic Edge Ltd also has a range of high temperature laboratory vacuum / inert atmosphere furnaces with graphite hot zones. These furnaces can heat a crucible or wafer to 2100C. All furnaces are plc controlled and are fully interlocked, with simple one button pump / vent operation. A choice of PID temperature controllers enables a high degree of control and programmable temperature ramping and cooling functions. Dual zone temperature control on flat wafer furnaces gives very high uniformity across the substrate.
We can offer a complete range of technical ceramic materials and components including Shapal, Macor, Alumina, Boron Nitride, Aluminium nitride and Quartz. We can also offer CVD produced ceramics such as pyrotytic boron nitride PBN and pyrolytic graphite.
UIC, Inc. was established by Jerold Armstrong in 1965 as a manufacturer’s representative firm and has grown into a full manufacturing and R&D facility.UIC manufactures coulometric carbon and sulfur analysis systems, vapor pressure osmometers, and kinematic/dynamic viscosity systems.
Products and Markets:
The primary products for UIC are the coulometric carbon analysis systems. These systems are used extensively by the university, geological, oceanographic, petroleum and cleanliness verification markets. The carbon analysis systems have the ability to determine total carbon (TC), total organic carbon (TOC), total inorganic carbon (TIC) and surface carbon (SC) in solids, liquids, slurries and gases.
The coulometric detection system operates on the principles of Faraday’s Law and provides calibration free analysis of practically any material. Typical analysis times range from 5 to 8 minutes utilizing sample sizes from 10ug to 3g. The detection range for these systems is 10ug to 100mg of carbon per sample. This translates to an effective analytical range of 10ppm to 100% and will provide relative standard deviations below 0.2% when analyzing standard materials.
The osmometers are used primarily in the university and polymer manufacturing markets as a way to determine average molecular weights of soluble polymers from 100 to 1,000,000 Dalton.
The viscosity systems are used to determine kinematic viscosities of Newtonian fluids in the range of 0.3 to 100,000 centistokes.
UIC is dedicated to providing superior service and innovative solutions to our end-users needs. We maintain two research and development laboratories, an experienced product development staff, a fully equipped service department and a state-of-the-art machine shop to meet the ever changing needs of our customers.
UIC will strive to improve our already excellent customer support system and enhance our reputation as a world leader in instrumentation and pump technology.
