WitrynaType B: (High Viscosity) The Code 1248. For Normal Light Microscopy: Type A: (Low viscosity) This is the lowest viscosity (150 centistokes) of the different fluids and exhibits low fluorescence for short focus objectives. The Code 1248. Types A and B, with viscosities of 150 and 1250 cSt (centistokes), respectively, meet these requirements. WitrynaDescription. For use with 100X oil immersion objectives. Type B is recommended for most educational microscopy; contains no PCB compounds. Type A: Low …
Immersion Oil VWR
Before the development of synthetic immersion oils in the 1940s, cedar tree oil was widely used. Cedar oil has an index of refraction of approximately 1.516. The numerical aperture of cedar tree oil objectives is generally around 1.3. Cedar oil has a number of disadvantages however: it absorbs blue and ultraviolet light, yellows with age, has sufficient acidity to potentially damage objectives with repeated use (by attacking the cement used to join lenses), and diluting it with sol… WitrynaTypes A & B, with viscosities of 150 and 1250cSt respectively, meet these requirements. The greater the gap between cover glass and objective, or condenser and slide, the more desirable high viscosity becomes. For extremely large gaps, type NVH should be used. All Cargille Immersion Oils can be blended for intermediate viscosities. highcliffe post office opening times
