Product Categories
Gloveboxes
VST’s gloveboxes come as standalone products or in integrated configurations with additional equipment, such as gloveboxes integrated with deep vacuum ovens or gloveboxes integrated with thin-film deposition systems. VST provides complete laboratories featuring gloveboxes that combine dry glovebox capabilities, wet gloveboxes, spin coaters, plasma cleaning systems, laboratory equipment, and more.
Atomic Layer Deposition (ALD) Systems
ALD is a method of thin-film deposition by construction of monoatomic layers through alternating exposure of the substrate to 2 precursors in the gas phase, in a self-limited process. This method enables deposition of high precision nanometric dielectric, semiconductor or metallic layers on flat or three-dimensional substrates.
VST has developed a unique ALD system for coating small quantities of powders using a pulse-bed method. This system is used for R&D in leading academic institutions.

In-line Coating Systems for Large Models and Surfaces
VST designs and manufactures in-line sputtering systems for coating large flat substrates. These coating systems are built with multiple interconnected stations, where each station performs a specific stage of the process: loading station, primary vacuum, high vacuum, plasma cleaning, coating or multiple coatings, thickness measurement, return to atmospheric pressure, and unloading station. Coating is achieved using large, elongated sources that can coat the entire surface at once.

Arc Melting Furnace
VST’s arc melting furnace is designed for the melting of metals and ceramics at temperatures up to 3000°C. The heat generated by the arc melts metals and even ceramics to create alloys or to remove residues. The arc produces such high temperatures that even metallic residues can be uniformly melted in a short time, while the slag is continuously extracted and removed.
High Vacuum Furnace
High vacuum furnaces designed for thermal treatments in an oxygen-free atmosphere for small models, at high temperatures of 1000°C, 1300°C, and up to 1500°C. These furnaces are used for various applications in research and development, as well as in industry.

Ellipsometer for Measuring Layer Thickness - J.A. Woollam Ellipsometers
J.A. Woollam is the global leader in
the field of ellipsometry. Ellipsometry is an optical technique used to measure thickness and optical properties of thin layers, measuring the change in circular polarization upon reflection or transmission. An ellipsometer can help in assessing the quality of the thin films by including roughness, porosity and thickness uniformity. VST is the exclusive representative of J.A. Woollam and offers ellipsometers in various levels of complexity, ranging from a basic benchtop model to a model with moving sources and stages and a robotic system for production lines.
