Carbolite LHT High-Temperature Bench-Top Laboratory Ovens
The LHT series offers compact, bench-mounted ovens available in three chamber capacities—30 L, 60 L, and 120 L—and three maximum operating temperatures: 400 °C, 500 °C, and 600 °C. They come standard with an R38 PID temperature controller, a heavy-duty convection fan for uniform heating, and low-thermal-mass insulation for fast response and energy efficiency. The interiors are crafted from corrosion-resistant stainless steel and feature two adjustable shelves. Built for durability and continuous use, the exterior is zinc-coated and stoved with epoxy-polyester for added resilience. A range of optional accessories is available, including over-temperature protection, enhanced controllers, data logging, viewing windows, variable-speed fans, cable ports, exhaust fans, and stacking or floor-stand options.
