Olympus CK-30 inverted microscope with phase contrast, ergonomic binocular head, and 4x, 10x, 20x objectives for cell imaging
The Olympus CK-30 inverted microscope is designed for advanced biological and cell imaging applications, including molecular diagnostics and bioprocessing research. It features a fixed binocular ergonomic head with a tilting range of 30° to 60° and an adjustable eyepoint height up to 32 mm, enabling comfortable long-duration observations. The coaxial coarse and fine focus mechanisms utilize a revolver vertical movement system with precise adjustments: 39.6 mm travel per coarse focus turn and 0.2 mm per fine focus turn.
Its illumination system incorporates a 6V 30W halogen lamp with integrated frost and heat-absorbing filters for stable, neutral lighting essential for phase contrast microscopy. The microscope is equipped with a 3-hole phase contrast slider and objectives with specialized phase films and coatings to deliver high contrast, color-neutral images critical in live-cell imaging and fluorescence analysis.
Olympus's proprietary Relief Phase Contrast (PC) observation method enhances cell viability assessment by combining phase contrast with oblique illumination—an essential feature for biotechnology workflows such as gene editing and biomanufacturing. This inverted microscope includes 4x, 10x, and 20x objectives and supports rapid, autofocus-free observation for efficient laboratory workflows.
This unit is used and sold as-is; performance may vary from new specifications. It is widely regarded in biotechnology and cellular biology fields for applications demanding precise phase contrast imaging and ergonomic design, making it ideal for research in molecular biology, synthetic biology, and clinical diagnostics.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
