Guard columns offer a user friendly, compact design for easy integration. Iso-Prep™ is a guard cartridge system designed to protect valuable prep columns. Column Saver Precolumn Filters offers a biocompatible and economical way to add a filter to your system. Packing Adapters are available for connecting hardware to high pressure column packing reservoirs. We also offer a variety of tools to assist with your column usage.

Many applications require biocompatible hardware. To meet this growing demand we have developed a unique line of connectors. This product family includes column couplers. Our guard column connectors include different styles that deliver low swept volume and help maintain column efficiency.

Our Sample Trap Columns are optimized for protein and peptide separation/purification. We offer these columns in conductive and nonconductive, packed and unpacked versions. They are ideal for separating and concentrating and/or purifying biological samples for mass spectrometer. The heart of the Sample Trap is a fused silica capillary column. Available phases for our capillary columns include a Reversed-Phase, High Carbon Load C18 5µm/300Å Spherical Silica material and a SCX (Strong Cation Exchange) 5µm/85Å material.

NanoTight Fittings are specifically designed to connect 70 μm–1 mm OD capillary tubing to any standard 10-32 coned port normally intended for 1/16 inches outer diameter tubing using the NanoTight Tubing Sleeves. The fittings can also be used to connect any 1/16 inches outer diameter tubing.

Our PEEK Fittings with Knobs are biocompatible and offers excellent chemical resistance. We designed these fitting to be simple, economic, and easy-to-use. It comes in one and two piece options. The multi-colored knob is designed to allow for easy identification.

Our unique Two-Piece Fingertight Fittings feature a separate ferrule. With a two-piece design, you can replace just the ferrule instead of the entire unit, making these Fingertights more economical than the one-piece version. Use a standard knurled head fitting for traditional fingertight applications, or use a fitting with wings built into the head for extra tightening leverage. 

Our uniquely designed Bottom-of-the-Bottle Filters effectively protect your system by filtering out particulate matter that my otherwise damage expensive hardware. Our durable stainless steel specifically designed to allow solvents to be drawn from within 1/8 inches of the bottom of your bottle. Our UHMWPE version allows tubing to pass through to the bottom of the filter cup, enabling the filter to draw solvent from within 0.10 inches (2.5 mm) of the bottom of your solvent bottle. This widely known and durable polymer is an economical choice. Our PEEK version is biocompatible and includes two built-in PEEK frits. Our PEEK frit (2 μm or 10 μm) will draw solvents from within 0.080 inches (2.0 mm) of the bottom of the solvent bottle. The 2μm frit on the side may be used for a 1/8 inches outer diameter helium sparging line.

We offer general use, preparative and specialized versions of Inlet Solvent Filters for many applications. Our filters come in stainless steel and polymer versions for excellent chemical compatibility. We provide a wide selection of porosities and materials to meet your system requirements.
