The Organic Material Effusion Cell OME is specially designed for the evaporation or sublimation of high vapor pressure materials, notably sensitive organic substances, at operating temperatures up to 400°C. It can likewise be used for other materials typically evaporated at very low temperatures, e.g. alkali metals. Due to its patented Thermal Conduction Cooling with encapsulated heater unit, the OME offers drastically improved operation properties below the lowest temperature limit of common Knudsen-type effusion cells. The novel As an option we offer the TCC concept for the OME 100-75, which involves a liquid metal used as a thermal conductor that provides a direct thermal connection between crucible and heat reservoir, leaving no isolating voids. |
