Sepax Technologies Inc Sepax HPLC Column HPLC GUARD Column, Unix™ SEC-300, 1.8 µm, 4.6 x 20 mm
Utilizing proprietary surface technologies, Unix SEC-300 phase is made of uniform, hydrophilic, and neutral nanometer thick films chemically bonded to high purity and mechanically stabilized silica with the particle size of 1.8 µm. The combination of small particle size and large pore volume of Unix SEC-300 renders the highest separation efficiency and resolution of analytes. The well-controlled surface chemistry results in excellent lot-to-lot reproducibility. Our unique bonding chemistry, coupled with the maximized bonding density, allows Unix SEC-300 to provide high stability and negligible non-specific interactions. Typical applications for Unix SEC-300 columns include separation and analysis of biological molecules and water-soluble polymers.
Optimize Technologies OPTI-GUARD 1mm Guard Column, C18 (Violet 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.
