HPLC Guard Columns and Cartridges
Waters Corp Cartridge, BioResolve SCX mAb, 3 μm, 2.1 mm X 5 mm
These VanGuard Fully Integrated Technology (FIT) Replacement Cartridges contain 3 μm particles and are designed to protect columns from performance drops due to fouling by removing particulate contaminants. They seamlessly integrate into existing workflows. This reusable solution maintains the same inner diameter and pH range as the corresponding column for chemical and mechanical stability. While not a substitute for proper sample purification, these cartridges extend column lifetimes.
- Designed exclusively for use with 3 μm columns with included VanGuard Fit option.
- Seamlessly integrates into existing workflow to provide enhanced protection from particulate contaminants.
- Reusable solution for column protection.
- Offers the same inner diameter and pH range as the corresponding column for chemical and mechanical stability.

Sepax Technologies Inc Sepax HPLC Column PolyRP-1000, 10 µm, 4 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
Optimize Technologies EXP2 Replacement Stems, 2.6µL, 3.0µm EXP, HILIC, 3pk
Specialized features, patented technology, precision engineering and state-of-the-art manufacturing make the new EXP2 Stem Trap an unbeatable choice for ultra high-pressure trapping applications. Its slim architecture allows it to easily fit into crowded instrument compartments or to connect directly to tightly-spaced injection ports. When tightened by hand, the EXP2 Stem Trap seals to 8,700+ psi. Additionally, the product can be wrench tightened to 20,000+ psi (1,400+ bar). The unique packed floating stem installs directly into any 10-32 port and automatically adjusts to provide a perfect ZDV connection. The new EXP2 design incorporates an integral ferrule into the front-end of the holder so there is no separate ferrule to lose! The replacement stems are also low volume/ low-dispersion, intended for many repeat uses and is available with various bed volume and custom packing options. This product is recommended for nano flow applications. For use with EXP™2 Stem Holder Only
