TvU Research Equipment - You specify it, we design it, make it, and test it.

• Research Furnaces: We specialize in research laboratory furnace systems that do what you need to do, not a standard furnace that you must adapt after purchase.

• Optical Systems: optics trains, windows, lasers, detection systems, optical diagnostics; learn through optical monitoring.

• Flow and Vacuum Systems: move the fluids the way you want to.

• Heat Transfer Systems: heating, cooling, insulation - control your temperature.

Research and Development

• Multidisciplinary Applied Physical Sciences - Many different technical areas simultaneously.

We try to help you do what you want to do. We use what equipment you have if you want to spend less. New or used equipment - your choice.
