Replacement Microscope Accessory for Biological Microscopes This replacement part restores reliable mechanical and optical performance for RMSthreaded biological microscopes. It combines a precision copper core and robust stage construction to provide a stable mounting and long service life. Key benefits Direct replacement for broken or worn components: standard RMS thread and 20.2mm mounting size allow easy installation on compatible biological microscopes. Stable optical spacing: designed to accommodate the standard 0.17mm cover glass thickness used in biological microscopy, helping maintain correct focal plane and image quality. Durable construction: precision copper core and a moveable stage made of quality plastic and metal deliver mechanical stability and extended lifespan. Consistent dimensions: 160mm tube length ensures predictable optical path and compatibility where this tube length is required. Specifications Material: precision copper core Tube length: 160mm Thread: standard RMS thread Mounting size: 20.2mm Compatible cover glass thickness: standard 0.17mm for biological microscopes Stage construction: moveable stage made of quality plastic and metal How this product solves common problems Replaces damaged or nonfunctional parts to restore mechanical movement and sample positioning without needing a full microscope replacement. Provides correct mounting and optical spacing so objectives perform as intended with 0.17mm cover glass. Improves durability of frequently used microscopes through higher quality materials in the stage and core. Typical applications Classroom and teaching labs: a damaged stage or tube assembly to get lab microscopes back in service quickly. Routine maintenance for research or industrial labs: swap in this component during equipment servicing to restore stable mounting and correct optical spacing. Field or onsite repairs: keep a spare part available to minimize downtime when microscopes are used in outreach, inspection, or mobile lab settings. Compatibility note Intended for biological microscopes that accept standard RMS thread components and a 20.2mm mounting size. Confirm tube length requirements and cover glass thickness compatibility before installation.
