Cryogenic scanning electron microscopy allows observation of water-containing samples in a frozen condition that permits sample morphology to be maintained in high vacuum conditions and close to their natural state. This technique has been widely used in food, biology and pharmaceutical fields for a long time. Recently it has been applied for high resolution cryogenic microscopy of protein particles. We have tested the capabilities of the S-4700 coupled with an Oxford cryogenic system using yeast, colloid and other samples. The S-4700 has s snorkel objective lens and achieves a high resolution of 2.1 nm at a low operating voltage of 1 kV. The Oxford cryogenic system allows operation of the S-4700 at short working distances that are preferred for high resolution work.
Products & Services
Electron microscopes use a focused beam of electrons instead of light to "image" the specimen and gain information as to its structure and composition.
Biological microscopes are used to study organisms and their vital processes.
Metallurgical microscopes are used for metallurgical inspection including metals, ceramics, and other materials.
Measuring microscopes are used by toolmakers for measuring the properties of tools. These microscopes are often used for dimensional measurement with lower magnifying powers to allow for brighter, sharper images combined with a wide field of view.
Digital and video microscopes are instruments that use digital technology to magnify images of objects. They include built-in cameras and a series of high-powered lenses that provide superior image quality and resolution.
