Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, SRT SEC-2000, 5 µm, 7.8 x 50 mm, Light Scattering SEC
Utilizing proprietary surface technologies, SRT SEC phases are made of the uniform, hydrophilic, and neutral nanometer thick films chemically bonded on the high purity and enhanced mechanical stability silica. This proprietary surface technology results in excellent column-to-column reproducibility. The nature of the chemical bonding and the maximum bonding density of the thin film benefit SRT SEC phases with high stability and negligible non-specific interactions. Along with the widest pore size selection of 100, 150, 300, 500, 750, 1000 and 2000Å, SRT SEC packings have highest capacity that enables highest resolution.
Waters Corp Viridis BEH VanGuard Pre-column, 130Å, 3.5 µm, 2.1 mm X 5 mm, 3/pk
The Viridis sub-2-µm and 3.5 µm columns demonstrate high efficiency and resolution. The reduction and control of surface silanol activity on Viridis particles delivers, under SFC conditions, excellent peak shapes — without the use of mobile-phase additives — even for well-retained basic achiral compounds.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 5 µm, 300 Å, 4 x 10 mm
Wide range of pore sizes and high compatibility with 100% aqueous phases make Bio-C18 columns ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. The specially designed surface bonding chemistry and the pore sizes allow for extended retention and selectivity for polar and hydrophilic compounds, such as peptides and amino acids. C18 monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
Waters Corp BioResolve Phenyl Guard Column, 450Å, 2.7 µm, 2.1 mm X 30 mm, 1/pk;
BioResolve Phenyl Guard Column, 450Å, 2.7 µm, 2.1 mm X 30 mm, 1/pk;
Eagle Biosciences Inc Nephrolyx UHPLC Guard Column, UHPLC Guard Column – to be used with Nephrolyx RUO Test Kit
The Nephrolyx UHPLC Guard Column is a UHPLC Guard Column to be used with the Nephrolyx RUO Test Kit. For research use only.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 3 µm, 300 Å, 2 x 10 mm
Wide range of pore sizes and high compatibility with 100% aqueous phases make Bio-C18 columns ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. The specially designed surface bonding chemistry and the pore sizes allow for extended retention and selectivity for polar and hydrophilic compounds, such as peptides and amino acids. C18 monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
Optimize Technologies EXP™Guard Column Cartridge, 2.1mm x 10mm, SCX, 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 Styragel Guard Column, 20 µm, 4.6 mm X 30 mm, 100 - 10K, Toluene, 1/pk
These Styragel Guard columns protect and increase the column lifetime of your Styragel 7.8 mm or 4.6 mm ID columns.
Waters Corp DeltaPak C4 Radial-Pak Guard, 300Å, 15 µm, 25 mm X 10 mm, 2/pk
Delta-Pak packings, ideal for the separation of peptides, proteins, and natural products, are based on a highly stable, bonded, endcapped 5µm or 15µm spherical silica. Delta-Pak is available in two different pore sizes (100Å and 300Å) with either C4 or C18 bonded phase. Delta-Pak packings are available in different cartridge and column configurations, providing consistent and predictable scale-up capabilities for milligram-to-gram scale purification. Also, by having the same chemistry available on a high-efficiency 5µm particle, you can easily check the purity of your fractions.
