Chemical Vapor Transport (CVT) Furnace

    The Chemical Vapor Transport (CVT) Furnace is a high-precision, multi-zone tube furnace engineered specifically for growing and purifying single crystals via vapor phase transport. Leveraging finely tuned linear temperature gradients, this system supports controlled sublimation and recrystallization, making it essential for solid-state chemistry, crystal engineering, and semiconductor materials research. 

    By enabling precise manipulation of transport agents, gas environments, and temperature differentials, the CVT Furnace provides an ideal environment for days-to-weeks long crystal growth cycles—with the stability and uniformity needed for reproducible outcomes.
