Scope Instrument Services repair, service & align all makes & models of microscopes on-site. Our service manager has 34 years experience in servicing compound, stereo (dissecting), fluorescent, metallurgical, inverted & phase microscopes. There is no NATA certification specific to microscopes, as there are no calibratable points. AIOH Technical Paper 2018, Asbestos Analytical Equipment Calibration Requirements recommend a minimum interval of 12 months for the servicing and alignment of microscopes. For microscopes that are in operation all day, as is often the case in Anatomical Pathology, Cytology, Haematology and Microbiology, we recommend six monthly servicing.
