The McCrone 10X Dispersion Staining Objective
SKU:289-F2
Dispersion Staining is a means of rapidly determining the refractive index of a particle by imparting characteristic colors to colorless objects. The technique is based on the difference between refractive index dispersions of the particulate solid and liquid medium in which the solids are immersed.
Complete McCrone Instrument Set
SKU:120SET
An ideal set for the serious microscopist. Includes all necessary items for a variety of tasks.
IMA Reticle
SKU:296K100
Used for USP 788 microscopic particle count test.
Micrometer scales, grids, circles and selected designs are suitable for use in the eyepieces of all microscopes for measurement, gauging, counting, comparison and absolute size determination. Three standard reticle diameters are available: 19mm, 21mm and 24mm.
Interference Filter (50mm round)- 589nm D Line
SKU:365D
Interference filters transmit only a narrow band of the spectrum and thus are essentially monochromatic filters. Three transmit at wavelengths 656nm, 589nm and 486nm corresponding to the C, D and F spectral lines respectively. The fourth filter transmits near 546nm (green) and is necessary for quantitative interference microscopy such as Berek or Sénarmont compensation
Cargille High Dispersion Sets
Refractive index liquids are used worldwide for the identification of particles by microscopic immersion techniques, mounting media for matching/contrasting index combinations, dispersion staining, and to calibrate refractometers and other instruments.
