If you're running flash chromatography in your lab, you already know columns are a recurring cost that adds up fast. Whether you're purifying reaction mixtures in drug discovery, isolating natural products, or running routine separations in QC, the 4g to 120g normal-phase silica range is where most of your spend lives.
That's exactly where Modus flash columns deliver.
The Modus range gives you options matched to how you actually work:
Modus B-Series (Basic). Same cartridge construction as the S-Series, packed with high-quality silica gel (40–63μm, 60Å) or alumina (50–75μm). Alumina options are particularly useful when your sample is sensitive to degradation on silica. B-Series offers excellent savings for everyday purification without compromising on consistency.
Modus S-Series (Standard). Machine-packed with ultra-pure silica featuring tight particle size distribution, low trace metals, and controlled water content. Our unique dry packing technique guarantees high resolution and reproducibility, run after run. Max operating pressure up to 300psi with Luer Lok universal compatibility, so they'll fit your existing system straight out of the box.
Modus P-Series (Premium). When you need more from your columns. Spin-welded heads and extra-thick walls handle up to 400psi, guaranteed leak-free. Available in both silica and bonded phases (C18, amino, and more). The real kicker: they're reusable up to 20 times on average, making them an economical substitute for preparative HPLC.
Modus eTWIST. An innovative open-top design for flexible sample loading. Choose pre-packed, empty cartridges for self-packing, or eTWIST Plus pre-packed with 15% empty space for solid sample loading. Ideal for labs that want full control over their loading method.
Most labs buy flash columns from large distributors and pay inflated prices for what is, ultimately, silica in a plastic cartridge. The Modus range delivers the same performance you'd expect from the big-name brands, ultra-pure silica, universal Luer-Lok compatibility with all major flash systems (Biotage, CombiFlash, puriFlash, and more), and sizes from 4g to 120g+, but at genuinely unrivalled prices.
We're not a reseller marking up someone else's product. We're chromatography specialists, and flash purification is what we do.
Your lab budget should go further. Make it happen.
