The new Keldahl decomposition device is a decomposition system using an aluminum block heater that enables rapid Keldahl decomposition or wet heating decomposition of various samples according to customer applications, thanks to its combination with a high-precision temperature controller. It features a full model change with a corrosion-resistant enamel coating and is equipped with LED lights to enhance visibility during decomposition. Additionally, it is possible to install an optional fan for air cooling, which also considers the reduction of total decomposition time.
