A total humidity removal inside rock specimens is crucial before certain studies, e.g. gas permeability or porosity measurements. The system includes a heated desiccator and a vacuum pump. The main components of the portable oven are a machined stainless steel heating plate (Option: Heating plate with Teflon coating) and a glass bell, designed to withstand the internal and external pressure difference. The sealing is secured by a Viton O-ring between the heating plate and the bell.  A small volume and compact design guarantee a fast heating process.
