16、ISO 8036:2015Microscopes Immersion liquids for light microscopy 1 Scope This International Standard describes the characteristics of immersion liquids used in microscopy. It classifies immersion liquids according to their field of application and specifies requirements and test methods for each type

17、. This International Standard further specifies a system of designation for immersion liquids, the information to be included on container labels, and the information to be supplied in technical data sheets. 2 Normative references The following documents, in whole or in part, are normatively referen

20、ied as follows: type N: immersion oil for general use in light microscopy; type F: immersion oil which meets the requirements of fluorescence microscopy; type G: spectrally pure glycerol (commonly known as glycerine) for glycerol immersion. 4 Characteristics of immersion liquids 4.1 Optical properti

21、es The optical properties of immersion liquids are defined by the refractive index at the wavelength = 546,07 nm, n e , at a defined temperature (23 C) and pressure (1 013,25 hPa), as well as by the Abbe number (reciprocal of the dispersive power), v e . The Abbe number, v e , is calculated using Fo

22、rmula (1): n nn (1) where n F is the refractive index at = 479,99 nm; n C is the refractive index at = 643,85 nm. INTERNATIONAL ST ANDARD ISO 8036:2015(E) ISO 2015 All rights reserved 1BS ISO 8036:2015ISO 8036:2015(E) The refractive indices are usually measured with an Abbe refractometer at constant

23、 temperature with a tolerance of 0,1 C. A mercury-cadmium spectral lamp is used as the light source. 4.2 Transmittance Modern detection methods in light microscopy require an extension of the spectral range of immersion liquids. The transmittance is measured using a suitable spectrophotometer in qua

24、rtz cuvettes with an optical path length through the immersion liquid of d = 10 mm against an empty reference cuvette. 4.3 A ut ofluor esc enc e The autofluorescence of immersion liquids is measured with a fluorescence spectrometer. Quinine sulfate in 0,05 mol/l sulfuric acid is used as the fluoresc

25、ence standard. For the fluorescence measurement, the following excitation and emission wavelengths are used: F(365 nm/450 nm) = fluorescence excitation at 365 nm, measurement of fluorescence emission at 450 nm; F(405 nm/485 nm) = fluorescence excitation at 405 nm, measurement of fluorescence emissio

26、n at 485 nm. As the fluorescence emission decreases during the measurement, the autofluorescence of immersion liquids is averaged over a measurement time of 60 s. Immersion liquid samples and standard liquids are measured in a fluorescence cuvette made of quartz or special optical glass with an opti

27、cal path length through the immersion liquid of d = 10 mm. The reagents used shall meet the quality standards for fluorescence spectroscopy. Prepare a quinine sulfate stock solution of 500 mg/l with 0,05 mol/l sulfuric acid. Before use, prepare two standard solutions of 0,1 mg/l and 2,5 mg/l quinine

28、 sulfate in 0,05 mol/l sulfuric acid by diluting the stock solution 1:5000 and 1:200, respectively. Store the stock solution in a closed brown glass bottle at 6 C to 12 C for no more than two months. Always prepare the standard solutions fresh on the day of use. As an alternative to quinine sulfate

29、solution, solid-state fluorescence standards with the same shape as a 10 mm cuvette may be used. These shall be calibrated against a quinine sulfate standard solution at least once a year. NOTE 1 Solid-state fluorescence standards are available as spectroscopy accessories. The information regarding

30、the autofluorescence of the immersion liquids is given in terms of the equivalent amount of quinine sulfate, in mg/l. NOTE 2 Quinine sulfate is more suitable for use as a fluorescence standard than rhodamine B because immersion oils tend, like quinine sulfate, to emit in the blue region in the case

31、of UVA excitation, while rhodamine B emits in the green region. 4.4 Viscosity The viscosity of the immersion liquid shall be measured by means of a capillary viscometer, e.g. an Ubbelohde viscometer, at a temperature of 23 C. 4.5 Density The density of the immersion liquid shall be measured at a tem

32、perature of 23 C by means of a hydrometer or a pyknometer.2 ISO 2015 All rights reservedBS ISO 8036:2015ISO 8036:2015(E) 5 Minimum requirements See Table 1. 6 Ingredients Immersion liquids conforming to this International Standard shall not contain ingredients which are known to have any adverse eff
