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.

• Capabilities

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.
