| ultrafiltration |
Ultrafiltration is a filtration process in chemistry that can retain solutes with relative molecular masses in the order of 100s to 1000s.It is also used in haemodialysis to clean whole blood while keeping its composition intact. In biological terms this occurs at the barrier between the blood and the filtrate in the renal corpuscle or Bowman's capsule in the kidneys. The Bowman's capsule contains a dense capillary network called the glomerus. ...

| ultramicroscope |
The ultramicroscope is a system of illumination for extremely small objects such as colloidal particles, fog droplets, or smoke particles. The objects are held in liquid or gaseous suspension in an enclosure with an intensely black background (usually a black body) and illuminated with a convergent pencil of very bright light entering from one side and coming to focus in the field of view - the "Tyndall cone" familiar in experiements on scattering. ...

| ultramicrotome |
A microtome is a mechanical instrument used to cut very thin slices for microscopic examination. Most microtomes use a steel blade and are used to prepare sections of animal, plant or human tissues for histology. The most common applications of microtomes are: * Traditional histological technique: tissues are hardened by replacing water with paraffin. Sections are stained and examined with a visible light microscope. Sections are 2 to 10 micrometres thick. ...

----Ultraviolet (UV) radiation is electromagnetic radiation of a wavelength shorter than that of the visible region, but longer than that of soft X-rays. It can be subdivided into near UV (380–200 nm wavelength) and extreme or vacuum UV (200–10 nm). ...
