HPLC Guard Columns and Cartridges
Waters Corp DeltaPak C4 Radial-Pak Column, 300Å, 15 µm, 47 mm X 300 mm, 1/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.
Waters Corp Porasil Silica Radial-Pak Guard, 125Å, 15 - 20 µm, 25 mm X 10 mm, 2/pk
Waters Porasil 15 - 20µm silica packing material provides long column life and low backpressure. The packing also has a high surface area making it ideal for preparative work.

Waters Corp Bondapak C18 Radial-Pak Guard, 125Å, 15 - 20 µm, 25 mm X 10 mm, 2/pk
Bondapak C18 is available in two different particle sizes, 15-20µm and 37-55µm, providing easy method transfer from µBondapak through preparative scale up. If you are developing a new purification protocol, Bondapak provides the best balance between resolution, throughput and cost.
Waters Corp Nova-Pak C8 Guard-Pak Insert, 60Å, 4 µm, 10/pk
The 4 µm small particle size of Nova-Pak bonded phases offers high resolution, more efficient and faster chromatography by using shorter columns, reducing solvent consumption or by using longer columns to resolve even the most complex mixture. Semi-preparative columns with 6µm particle size packings give you an unparalleled range of separation possibilities. Stringent QC procedures in our cGMP manufacturing facility ensure batch-to-batch reproducibility.
Waters Corp µBondapak C18 Radial-Pak Guard, 125Å, 10 µm, 25 mm X 10 mm, 2/pk
µBondapak C18 columns are general purpose, silica-based, reversed-phase C18 columns that are based on 10 µm particle technology. As a starting point for preparative chromatography, no other column can provide the balance between resolution, throughput and cost.

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, 1.5µL, 3.0µm EXP, C8, 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
