This method is useful for the qualitative identification of asbestos and the semi-quantitative determination of asbestos in bulk samples. This method measures the percentage of asbestos as perceived by the analyst in comparison to standard projections, photographs and experience. The quality of the results are dependant upon the skill and judgment of the operator. Asbestos PLM Microscopes for Bulk Fiber Identification (NIOSH 9002) The MT6120 and MT6130 Series has been designed as a versatile, modular, ergonomic microscope system which are ideally suited in education, research or advanced laboratory applications. Ergonomic placement of controls allows for stress free operation, increased lab efficiency and maximum productivity. Transmitted 6V 30W Koehler Halogen illuminator with strain free condenser and strain free ∞ Infinity Corrected objectives and a 10X Dispersion Staining Objective. The MT6120 and MT6130 Series offers an outstanding range of features and optical performance with an emphasis on all newly engineered high performance optics based on Meiji Techno's ICOS Optical System (Infinity Corrected Optical System). The new strain free optics, provide exceptionally bright, crisp images, with good color rendition and superior flat fields of view.
