🔬 Olympus U-URA universal reflected light vertical illuminator with 4-position rotatable filter cube turret⚡ 4-position filter cube turret — accommodates up to 4 fluorescence filter cubes (DAPI, FITC, TRITC, Texas Red, and others) for rapid channel switching🎯 Universal reflected light design — supports fluorescence epi-illumination as well as reflected light POL and DIC applications🏭 Made in Japan by Olympus — guaranteed OEM fit and optical alignment✅ SKU U-URA / Cat. 5-UR500 — excellent condition, significant savings vs. list price of $3,800 🔧 Product Description The Olympus U-URA is a universal reflected light vertical illuminator featuring a 4-position rotatable filter cube turret, designed for Olympus BX series upright microscopes. It mounts between the microscope body and the observation head, routing excitation light from an external light source through the objective to the specimen (epi-fluorescence configuration) and collecting the resulting emission or reflected light back through the same objective for observation. The 4-position rotatable filter cube turret allows up to four fluorescence filter cubes to be installed simultaneously — including standard sets such as DAPI, FITC, TRITC, and Texas Red — enabling rapid manual switching between fluorescence channels without removing or exchanging cubes between experiments. As a universal illuminator, the U-URA also supports reflected light polarized light (POL) and DIC applications in addition to fluorescence, making it a versatile multi-mode illuminator for research microscopy. Built to Olympus factory specifications (catalog number 5-UR500), the U-URA ensures precise optical alignment and consistent illumination performance across all installed filter positions. This unit is in excellent condition at a significant discount from the list price. 🔎 Typical Applications Multi-channel fluorescence microscopy — DAPI, FITC, TRITC, Texas Red, and other standard fluorophores with up to 4 cubes loaded simultaneously Immunofluorescence — multi-label fluorescence imaging of antibody-tagged targets in fixed tissue and cell samples Reflected light POL and DIC — polarized light and differential interference contrast in reflected light mode Live cell fluorescence imaging on BX series platforms requiring multi-channel capability Research microscopy requiring a versatile universal illuminator supporting both fluorescence and reflected light contrast modes 📊 Key Specifications Specification Details Olympus Part Number U-URA (5-UR500) Type Universal Reflected Light Vertical Illuminator Filter Cube Positions 4 (rotatable turret) Supported Filter Cubes DAPI, FITC, TRITC, Texas Red, and other standard fluorescence cubes Illumination Modes Epi-fluorescence, reflected light POL, reflected light DIC Country of Origin Japan HS Code 901190 Condition Excellent Universities and research institutions are welcome to purchase using an official purchase order.
