Semi-rigid black lacquered single gooseneck light guide with Ø4.5 mm fiber for precise light positioning in lab applications.
The Schott KL Series Single Gooseneck Light Guide 154.101 is a flexible light guide featuring a semi-rigid black lacquered gooseneck tubing with a diameter of 4.5 mm and length of 600 mm. Designed for precise light placement, this fiber optic illuminator accessory is ideal for applications requiring controlled, near shadow-free illumination. The gooseneck’s flexible yet stable construction allows for easy re-adjustment, ensuring reproducible light positioning critical for biotechnology workflows such as gene editing illumination setups, molecular diagnostics, and live-cell imaging where accurate light delivery impacts experimental consistency.
Key technical specifications include:
This light guide is widely used in cell imaging, bioprocessing illumination systems, and synthetic biology research instruments where precise control of lighting angles supports enhanced fluorescence analysis or microscopic observation. Its robust design suits laboratory environments requiring steady, customizable light source direction to improve visibility in biomedical engineering, clinical diagnostics, and other experimental setups involving delicate sample illumination.
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.
