COLD ISOSTATIC PRESS (CIP)
FUNCTION AND USE:
Cold isostatic pressing (CIP) is a convenient tool for producing powder compacts of advanced materials by applying uniform pressure. It is widely accepted as an effective forming method in ceramics and powder metallurgy. Cold isostatic pressing involves compacting powders, usually pellets (max. diameter 15 mm), by enclosing them in an elastomer mould. An elastomer mould is used because it has low resistance to deformation. Liquid pressure is then applied uniformly to the mould to compress it. You are left with a highly compact solid at the end of the process.
TECHNICAL SPECIFICATION:
The maximum pressure is 1000 MPa (1GPa), the inner basket’s diameter is 16 mm, and the compression/decompression speed is adjustable from 20 to 350 MPa/min.

SPIN COATING EQUIPMENT
FUNCTION AND USE:
Spin coating is a procedure used to deposit uniform thin films, layers, and coatings onto flat substrates. Usually, a small amount of coating material in liquid form is applied to the substrate’s centre, either spinning at low speed or not spinning at all. The substrate is then rotated to spread the coating material by centrifugal force. Holmarc’s Spin Coater is a dedicated tabletop system that spin coats small substrates in research laboratories with well-controlled spin process parameters. The high speed and duration range allows the user to achieve the desired thickness or thinness of the film. A vacuum chuck powered by an oil-less vacuum pump holds the substrate at the spinning head.

Spinning speed: 60 – 9999 rpm
Substrate diameter: 30 mm to 70 mm

Muffle furnaces
Function and use:
Muffle furnaces are suitable for laboratory testing in which exact temperature distribution, controlled increase and decrease of temperature, and controlled cooling are important, and where it is also desirable that the heating elements are not in the interior space with the samples. These include heating of material for heat treatment of metals, various sintering tests, calcination, determination of the softening or sintering point of materials, burning of samples, firing of enamels, etc. The stainless steel casing ensures a long service life of the furnace, the heating spirals are housed in quartz glass tubes – the spirals are thus partially protected against attack by aggressive substances that can be released from the charge. The programmable controller and the main switch are located on the front of the furnace.

QUANTACHROME INSTRUMENTS AUTOSORB IQ-C-XR (1 STAT)
FUNCTION AND USE:
Autosorb iQ is the most advanced and flexible multifunctional, fully automatic gas adsorption analyzer, with 1 micropore analysis station, covering specific surface area and pore size distribution analysis using BET, t-plot, BJH and NLDFT methods. It is possible to perform various physisorption and chemisorption analysis. The autosorb iQ performs the most challenging measurements of non-porous, mesoporous, and microporous materials with accuracy and precision.
TECHNICAL SPECIFICATION:
- The autosorb iQ operates by measuring the quantity of gas adsorbed onto or desorbed from a solid surface at some equilibrium vapor pressure by the static volumetric method. The data are obtained by admitting or removing a known quantity of adsorptive gas into or out of a sample cell containing the solid adsorbent maintained at a constant temperature below the critical temperature of the adsorbate. As adsorption or desorption occurs the pressure in the sample cell changes until equilibrium is established. The quantity of gas adsorbed or desorbed at the equilibrium pressure is the difference between the amount of gas admitted or removed and the amount required to fill the space around the adsorbent (void space).
- The autosorb iQ AG has the capability of measuring adsorbed or desorbed volumes of nitrogen at relative pressures (P/Po) in the range 0.001 to slightly less than 1.0. When the micropore options are added, the lower limit is extended to 1×10-7 or 1×10-8. This volume-pressure data can be reduced by the autosorb iQ software into BET surface area (single and/or multipoint), Langmuir surface area, adsorption and/or desorption isotherms, pore size and surface area distributions, micropore volume and surface area using an extensive set of built-in data reduction procedures.
- ASiQwin software interfaces the autosorb iQ to a computer for data acquisition, data reduction, and archiving.
- The autosorb iQ has the ability to analyse physisorption for 90 hours without the need for refrigerant recharge.

Equipment for coating of solutions and suspensions by spray technology
Function and use:
The spray coater is a multifunctional industrial instrument employed for the purpose of depositing a uniform and thin film of liquid or suspension onto a given surface. The ND-SP-Precision Spray Coater operates by applying pressure to the material, causing it to atomize into small droplets or particles.

| NIR Fibre-optics spectrometer, Ocean Optics NIRQUEST 256-2.5 |
| Function and use: |
| The fibre optic spectrometer allows the measurement of spectra in the near infrared region (in the wavelength range 900-2500 nm) on selected very small regions on irregularly shaped or very large samples that cannot be accommodated in standard spectrometers using fibre optics. Due to its portability, it also allows connection to other equipment, e.g. an optical microscope with a heating stage, and the acquisition of spectra from samples placed in these devices at both laboratory and elevated temperatures |

Laboratory of surface treatment of glass in semi-operational conditions
Pilot coater for glass surface treatment under semi-operating conditions
FUNCTION AND USE:
This pilot coater replicates industrial glass surface treatment. It is designed for the research, development, and testing of advanced optical coatings on glass substrates in a semi-industrial production scale. This device is semi-automatic and fully programmable recipes that allows researchers and industrial experts to fine-tune the deposition parameters and evaluating coatings performance while ensuring reproducibility and repeatability. The coater integrates hybrid HC-PECVD (hollow cathode plasma enhanced chemical vapor deposition) and PVD (physical vapor deposition) technologies in a same line, allowing to deposit novel multilayers with durable and precise material composition. This coater reduces the risk and cost of full-scale implementation and facilitate scalability studies.
