Agilent ZORBAX Bonus-RP UHPLC guard column with 1.8 µm particle size, 2.1 mm ID for reversed-phase chromatography.
The Agilent ZORBAX Bonus-RP UHPLC guard column (model 821725-937) features a 1.8 µm particle size and 2.1 mm internal diameter, designed specifically for use with ultra-high-performance liquid chromatography (UHPLC) systems. This guard column protects the main analytical column by removing particulates and strongly retaining matrix components during reversed-phase chromatography workflows. It is essential for ensuring column longevity and reproducibility in biotechnology and molecular diagnostics applications, particularly for bioprocessing and synthetic biology research requiring high-resolution separation of biomolecules. The column’s specifications optimize performance in UHPLC setups commonly employed in clinical diagnostics, pharmaceutical research, and biomedical engineering laboratories. This accessory supports robust UHPLC operation critical to gene editing analysis and biomanufacturing workflows, widely adopted by scientists focusing on live-cell analysis and protein purification. The product is supplied in sets of three and is fully tested for immediate integration into analytical pipelines.
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.
