The basic Hitachi HU-11, without accessories, serves as a highly efficient electron diffraction apparatus for use with opaque or transparent specimens. With such accessories as a low temperature stage, a high temperature stage, a reflection microscopy attachment and a X-Ray shadow camera, the Hitachi HU-11 allows inves tigations into every field of research.
Meter Additives One or more additives can be pumped to a solution in the exact amount desired by selecting the correct size of t u b i n g a n d r e g u l a t i n g pump speed. Various con trols can be incorporated to close valves ahead of pump.
