Product description

High-stability C18 HPLC column for low pH (down to 1), up to 90°C, various particle sizes, and prolonged durability.

The Agilent ZORBAX StableBond C18 (SB-C18) is a high-performance liquid chromatography (HPLC) column engineered for exceptional stability and performance in low pH environments. This column is specifically designed to withstand highly acidic conditions, making it ideal for the analysis of compounds that require such settings.

Key features:

  • Superior low pH stability: Operates effectively in pH conditions as low as 1, ensuring reliable performance for acidic compound analysis.
  • High-temperature tolerance: Capable of withstanding temperatures up to 90°C, facilitating faster separations and enhanced method development flexibility.
  • Versatile particle sizes: Available in 1.8 µm, 3.5 µm, and 5 µm fully porous silica particles, accommodating both ultra-high-performance liquid chromatography (UHPLC) and traditional HPLC systems.
  • Excellent peak shape: Delivers sharp, well-defined peaks for acidic, basic, and neutral compounds, enhancing analytical accuracy.
  • Extended column lifespan: Non-endcapped C18 phase with bulky diisobutyl side chains protects the siloxane bond from hydrolytic attack, prolonging column durability.

The SB-C18 column is widely utilised across various scientific disciplines, including pharmaceutical research, biotechnology, environmental analysis, and food safety testing. Its robust performance under low pH conditions makes it particularly valuable in university laboratories, biomedical research centres, and clinical environments where precise and reliable chromatographic separations are essential.

Since its introduction, the Agilent ZORBAX SB-C18 has remained a cornerstone in chromatographic analysis, continuing to be a preferred choice for researchers seeking dependable and high-quality HPLC columns.

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
