Diamond Knife "TYPES"
TYPE SU: Standard Ultramicrotomy. For sectioning of biological or materials specimens that will be inspected at the highest magnifications. Recommended for cutting sections with a thickness range from 25 to 200 nm. Available in diamond edge lengths from 1 to 6 mm. Mounted in boat style S or any other requested style.
TYPE CW: Cryo Ultramicrotomy Wet. For sectioning at cryogenic temperatures down to -200° C using liquids, like ethylene glycol, to float the sections. Recommended for cutting sections with a thickness range from 50 nm to 1 µm. Available in diamond edge lengths from 1 to 6 mm. Mounted in boat style W.
TYPE CD: Cryo Ultramicrotomy Dry. For sectioning dry at cryogenic temperatures down to -200° C. Recommended for cutting sections with a thickness range from 50 nm to 1 µm. Available in diamond edge lengths from 1 to 6 mm. Mounted in boat style D.
TYPE TS: Thick-Thin sectioning. For sectioning thick or alternating thick and thin sections. Recommended for cutting sections with a thickness range from 50 nm to 2 µm. Available in diamond edge lengths from 1 to 6 mm. Mounted in boat style S or any other requested style.
TYPE MT: Materials Science. For industrial materials sectioning, not tested to the same ultra high standards as the types above, hence its lower price. Recommended for cutting sections with a thickness range from 50 nm to 2 µm. Available in diamond edge lengths from 2 to 7 mm. Mounted in boat style S or any other requested style.
TYPE LC: Light Microscopy Cryo. Sectioning for light microscopy or histology applications at cryogenic temperatures wet or dry. Recommended for cutting sections with a thickness range from 0.1 to 5 µm. Available in diamond edge lengths from 4 to 7 mm. Mounted in boat style W or D for wet or dry sectioning respectively.
TYPE LH: Light Microscopy or Histology. Sectioning for light microscopy or histology applications at room temperatures. Recommended for cutting sections with a thickness range from 0.1 to 5 µm. Available in diamond edge lengths from 4 to 7 mm. Mounted in boat style K, or other boat style upon request.
Diamond Knife Included Angles
The standard included angle for all knife types is 45° which is suitable for most applications. Micro Star diamond knives are also available with included angles of 35° and 55°. Knives with 35° reduce morphological deformation but the edge is more fragile. 55° is recommended for routine sectioning of hard or difficult to cut specimens.
Flawless Quality Guarantee
Micro Star diamond knives have an extremely sharp and perfect edge which cut flawless sections totally free of chatter, compression, striations or other imperfections. Each knife is made one at a time undergoing multiple tests. The sections are examined at high magnifications optically and with the TEM. With every knife you get a signed certificate of quality with the parameters of the final test.
Micro Star guarantee is simple: Do not authorize payment until you have tested your new or resharpened diamond knife and are totally satisfied with its flawless quality. We request that you test your knife within 60 day after receiving it.
Boat Styles
All dimensions shown in millimeters. If you have a special use for a diamond knife requiring custom design, please contact us. We usually can accommodate those requests at no extra cost.
