SIGMAMOTOR PUMP Move Corrosive Liquids Material being pumped never comes in contact w i t h pump mechanism. W a v e ­ like motion of steel fingers forces m a t e r i a l t h r o u g h Tygon tubing. By changing size of tubing, capacity can be increased or decreased. Pump housing opens f o r removal and insertion of tubing.

Hitachi's guaranteed 8 Angstrom Unit resolution allows you to probe the very basic structure of matter—making full use of the HU-ll's 250,000x direct magnification.

Feed and Mix One or more tubes can be feeding material to a mix while a larger tube is recir­ culating the liquid to pro­ duce agitation and thorough mixing. Viscous materials can be p u m p e d w i t h o u t danger of gumming or plug­ g i n g . Remove t u b e a n d pump is clean.

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.
