Perkin Elmer US LLC Brownlee Aquapore Octyl RP-8 NewGuard Cartridge - 15 mm x 3.2 mm I.D., Pkg. 3
Brownlee Aquapore Octyl RP-8 NewGuard cartridges are based on a spherical silica support suitable for the separation of large biopolymers. These cartridges prolong column life by 2 to 5 times while protecting columns from particulates and strongly bound sample components. Actual bed length of each 15 mm NewGuard is approximately 13 mm. These NewGuard Cartridges require a holder: To couple with a conventional column - NewGuard Holder (07150001) To couple with an MPLC cartridge - Union (07150018) Quantity: Package of 3 Interaction Mode: Reversed Phase USP Code: L7

Waters Corp Symmetry Shield RP18 Prep Guard Cartridge, 100Å, 5 µm, 19 mm X 10 mm, 1/pk
These reversed-phase columns contain Waters patented embedded polar group technology that “shields” the silica’ residual silanol surface from highly basic analytes. The reduced silanol activity for the SymmetryShield RP18 column significantly improves peak shape and resolution. This product needs to be used in conjunction with other parts.

Sepax Technologies Inc Sepax HPLC Column Antibodix WCX, NP3, 4 x 10 mm
Antibodix columns are specially designed for high resolution, high efficiency and high recovery separations of antibodies. The packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead. The non-porous resin has particle size of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. On the top of the hydrophilic layer, weak cation-exchange functional groups are attached via a proprietary chemistry, resulting in high capacity ion-exchange layer.
Sepax Technologies Inc Sepax HPLC Column GP-C4, 5 µm, 120 Å, 4 x 10 mm
Monomeric and fully endcapped GP-C4 packing is bonded with butyl groups that lead to moderate hydrophobicity. GP-C4 columns have unique selectivity and peak symmetry with moderate retention for separations of acidic, neutral and basic organic compounds, such as pharmaceuticals, peptides, and organic acids.
Sepax Technologies Inc Sepax HPLC Column Polar-Imidazole, 10 µm, 120 Å, 4 x 10 mm
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents, Polar-Imidazole phase is bonded with imidazole functional groups. With a polar and N-containing ring structure, Polar-Pyridine phase is a weak base and adequate for many applications, such as pharmaceuticals, peptides, sugars, and nucleotides.
Mac-Mod Avantor Ultrasphere Octyl, 80 Å, 3 µm, 4.6 x 5 mm Guard Cartridges (2/pk)
Avantor Ultrasphere is widely referenced within industry and academia and provide excellent chromatographic performance. Avantor Ultrasphere columns provide reproducible results, column to column, lot to lot.
Optimize Technologies EXP2 Replacement Stems, 0.17µL, 2.7µm HALO, RP-Amide, 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
