First prototypes of the new E Elrog molybdenum plate 300B fresh from the vacuum pump. This new 300B will not substitute the existing ER300B but will be a top-tier version, as it was already done with the ER242 and ER284, the molybdenum plate equivalents of the ER211 and ER845.
Molybdenum as a plate material presents a remarkable difference with the ER242 and ER284, it was a logical step to also introduce the Elrog molybdenum 300B.
