Transversal section through the middle pieces. The dense core is the mitochondrial derivative flanked on one side by the flageltum and on the other by a series of laciniate appendages of the head. 60,000 X.

MICROSCOPY
The quality of the section, whether it is biological material, synthetic fibre or metal, is as important to picture quality as the performance of the electron microscope itself.
®
THE ULTROTOME A complete ultra-microtomy lab which • Speeds research by eliminating the element of chance from ultra-thin sectioning • Provides ultra-thin serial sections of uniform thickness with no extra trouble to the operator • Cuts thick sections in sequence with the ultra-thin whenever desired • Produces large-area sections without wrinkles
Cutting high-quality sections requires a high-quality ultramicrotome. The LKB Ultrotome produces unlimited quantities of superior sections. It matches the work capacity and resolving power of the best electron microscopes available.
