HPLC Guard Columns and Cartridges
Waters Corp Waters Sentry Guard Cartridge, C8, 100Å, 5 μm, 2.1 mm X 10 mm
SunFire C8 columns are used for general purpose method development at low pH. The C8 ligand is preferred for some assays because it is less hydrophobic and therefore less retentive compared to SunFire C18.
- C8 chemistry for general purpose method development at low pH.
- Less hydrophobic and less retentive C8 ligand compared to C18, suitable for specific assays.
- Spherical silica particle substrate.
- Particle size of 5 μm and pore size of 100 Å.
- Designed for HPLC systems.
- Maximum pressure rating of 6000 psi (415 bar).
- Available in a 2-pack.
Mac-Mod Princeton HA-DEA (Diethylamino) 60 Å, 5 µm, 2.1 x 10 mm Guard Cartridges (5/pk)
Princeton Chromatography Achiral SFC columns are designed and manufactured in the US, well known for innovating novel and robust workhorse phase chemistries, for the analysis of achiral SFC applications. Princeton designs myriad phase chemistries to improve the selectivity and efficiency of SFC analysis. Known for originally innovating the 2-EP phase chemistry, explore what Princeton has to offer. Columns are available from analytical to preparative sizes and are available in a wide range of pore sizes, particle sizes, column ID's and lengths.

Med Vet International Surgical Instrument Guards, Assorted Pack, J0926S, Set of all 9 Sizes
JorVet instrument guards are designed to protect valuable instrument tips from damage during sterilization and handling. Sharp and pointed tips can break through sterilization pouches and injure the surgeon. 50/pkg.Non-sterile, but can be autoclaved or gassterilizedMedical-grade plastic (vented)Guards can also work as covers over exposed bone pins.
Optimize Technologies EXPGuard Column Cartridge, 4.6mm x 5mm, C18, 3µm, 3pk
The EXP™ Guard Column cartridge system is rated to 15,000psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP™ Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn™ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/ outlet. The combination of low-dispersion and ultra high-pressure capabilities provides effective protection with negligible effects on retention time, plate count, and peak shape. Use with EXP™ Direct Connect and In-line Holders.

Waters Corp XBridge Premier BEH C18 VanGuard FIT Column, 3.5 μm, 4.6 mm ID, 250 mm Length
The XBridge Premier BEH C18 sorbent, with a 3.5 μm particle size and dimensions of 4.6 x 250 mm, functions as a workhorse for method development and can be utilized across a mobile phase pH range of 1-12. Its trifunctionally bonded C18 ligand offers a universal column suitable for most LC separations, providing the widest usable pH range, superior low pH stability, and ultra-low column bleed.
- Delivers exceptional separation performance, robustness, and throughput for HPLC assays, while also enabling a smooth transition to UPLC adoption.
- Incorporates MaxPeak High Performance Surface hardware technology, which significantly lessens unwanted analyte/surface interactions that can cause poor peak shape and reductions in signal intensity.

Sepax Technologies Inc Sepax HPLC Column PolyRP-500, 10 µm, 2 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.
