HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 3 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.

Optimize Technologies OPTI-GUARD™ 1mm Guard Column, DVB (White Label), 5pk
OPTI-GUARD™ sets the standard for extremely low impact, easy to use pre-column protection. Designed for use with analytical (4.6, 3.0 mm i.d.) and narrow-bore (2.1, 1.0 mm i.d.) columns, the patented floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection every time. The best part? It's no larger than a standard fitting. Connecting the OPTI-GUARD™ requires no extra tubing, maintaining the minimal impact philosophy that has made the OPTI-GUARD™ line so popular. As always, custom packing is available. Key Features include: 5 disposable hand-tight holders and cartridges, a ZDV Connection, automatic adjusting to any manufacturer's column, no extra tubing is required for connection, the product does not effect chromatography, and it is no larger than a standard fitting.

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.
