JASCO V570 UV-VIS-NIR spectrophotometer
The spectrophotometer is used to measure: a) Absorbance or transmittance of a sample in the UV-VIS-NIR range; b) Film thickness calculation based on transmission and reflection spectra of thin films ; c) Transmittance of liquid and solid samples; d) Reflectance of solid samples; color analysis (tristimulus values, chromaticity coordinates, lightness, hue, chroma, color differences based on the XYZ Color System – CIE); e) Solar Direct Transmittance/reflectance measurement – calculates the transmittance and reflectance of both solar radiation and visible light ; f) Analyze thin films on planar surfaces.
JASCO FP6500 spectrofluorimeter
Spectrofluorimeter is used for: a) Recording emission and excitation fluorescence spectra on powders, films and liquids; b) Color fluorescence measurement – measures the reflectance (% R) of a fluorescent sample and calculates the tristimulus values, chromaticity coordinates, brightness index and chromaticity index according to the XYZ color specification system established by CIE; b) Calculation of the solid state quantum efficiency in the fluorescence emission spectrum using the standard reflectance spectrum and the emission spectrum of the sample (using an integrating sphere – ISF 513).
JASCO FTIR 6300 spectrometer
The spectrometer can be used for: Measurement in transmission (in KBr pellets, liquids and gases in specific cells); Total attenuated reflectance (ATR-FTIR) – Analysis of liquids, pastes, powders, films and flexible solids; FTIR specular reflectance – Measurement of liquid surfaces, thin films, thin layers of creams, pastes with double transmission on absorption test cards; thickness of plastic films, measurement of films on metal substrates; Diffuse Reflectance (DRIFT) – Analysis of powders, rough surfaces and fibers in mixtures with KBr; dilution-free analysis using an abrasive sampling kit; 80 degree angle reflection for thin film characterization.
M17 – LUZEX 450E
The equipment is especially useful for researches on preparation, stabilization, characterization and application of disperse systems. Qualitative or semi-quantitative information about particle size and shape can be determined, by numerically counting the amount of particles within predetermined size fractions. The microscope has lenses which will enlarge the particles images, enabling to individually determine sizes of particles of minimally 1 µm diameter. The system is equipped with an OPTIKA 3Mpx optical camera, and the images are processed with ProView software.
XENOTEST 150 S+
Color fastness to light is normally assessed using a high intensity filtered xenon arc lamp to simulate natural daylight. A set of blue wool standard fabric strips that fade at known rates must also be used in each test. The degree of fade is based on the spectrophotometric evaluation in the CIELab system on the test sample compared with the equivalent degree of fade on the blue wool samples.
Discover 2.0
The Discover® 2.0 is the premier microwave reactor for performing any organic or inorganic synthetic chemistry. Featuring a best-in-class 300 mL single-mode microwave cavity and intuitive software with a 10″ touchscreen interface, it is possible to program a reaction in seconds and achieve the best synthetic yield in minutes. For the first time, a single-mode microwave synthesizer reactor utilizing iWave, an intelligent IR sensor that can see through glass and Teflon and measures the temperature of your sample NOT the vessel!
Ultrasonic processor & atomizer
The VCX 750 is a powerful and versatile ultrasonic liquid processor. Using a variety of accessories, the system can process a wide range of sample types and volumes for many different applications. The 750 watt power supply has the capability of operating our largest assortment of horns and accessories. A standard 1/2″ diameter probe (50 – 250mL volumes) with replaceable tip is included with the system. Unlike conventional spray nozzles that rely on high velocity pressure to shear a fluid into small drops, the ultrasonic atomizer uses vibrational energy to generate a low velocity mist. Median droplet size is 50μm.
Nabertherm LE 6/11/R7
Furnace is a equipment intended for material processing processes through heat treatment, which requires high temperatures. The oven is equipped with high-quality insulating materials, which allow it to operate with low energy consumption and a short heating time. The oven chamber reaches a temperature of max. 1100 degrees Celsius.
Aplicator automat de film – MLBGD 219
The automatic film applicator enables the convenient pulling of a precise coating film on different substrates, thus reducing and eliminating errors caused by manual factors. Characteristics: touch-screen control panel; Programmable operation start/stop/stroke position; Real-time display for application speed; Adjustable speed 5-500 mm/s; Holding clamp for the test platform.
Aparat inregistrare timp de uscare – MLBGD 261
Dying Time Recorder, the equipment is necessary for determining the drying time of film-forming material. Characteristics: Simultaneous testing of 6 samples; Four different speeds: 6-12-24-48 hours – for any application; It complies with the standards: ASTM D 5895-03, ISO 9117-4; Calibration certificate.
