The Cascade Tek TVO-2 is a compact, benchtop vacuum oven designed for laboratory and production environments requiring precise temperature control within a vacuum atmosphere. Its applications include drying, curing, and degassing of materials sensitive to heat and moisture. The oven features a programmable temperature controller for automated processes, an integrated digital over-temperature protection system, and a digital vacuum gauge for monitoring vacuum levels. Its construction includes a stainless steel interior, aluminum shelves, and a powder-coated steel exterior, with a glass viewing window for sample observation.
