The UNIGUARD drop-in cartridge fits both our guard systems: the stand alone UNIGUARD and the Direct Connection UNIGUARD. Product detail: We recommend all analytical columns are protected by a guard cartridge, which is replaced on a regular basis. The ID of the analytical column determines the correct ID for the guard cartridge. We offer 10x1.0, 10x2.1, 10x3.0, 10x4.0 (for use with both 4.0 and 4.6mm ID analytical columns) i…

The 1260 Infinity II Preparative Column Organizer is a support module for purification workflows. It provides convenient and stable mounting of a manual injector and easily organizes both analytical and preparative columns from 4.6 to 50 mm inner diameter.

A Restek® LC guard cartridge in an EXP® direct connect holder is the ultimate in column protection.

Disks, Cartridges, well plates and more are available using a unique PTFE matrix membrane for unparalelled SPE

This new strong anion exchange resin offers an optimised macro-porous structure that ensures an efficient purification of large biomolecules, such as adeno-associated viruses (AAVs) and plasmid DNA (pDNA). With its high binding capacity for such molecules and high separation efficiency even at elevated flow rates, MacroSep IEX Q is a perfect addition to DSP platforms.

Designed to take advantage of low dispersion, ultra-high pressure UHPLC instruments, Avantor® ACE® Excel UHPLC columns give chromatographers more choices to achieve better results

Offers a wide range of bonded phases for every separation challenge

Evosphere® monodisperse fully porous particle columns lower band broadening by improving the homogeneity of the packing bed of the column, reducing the van-deemter curve, leading to increased efficiency and selectivity.

ACE UltraCore SuperC18 and SuperPhenylHexyl phases are manufactured using our unique Encapsulated Bonding Technology (EBT). This technology dramatically increases ligand coverage of the silica surface and effectively eliminates the negative effects of unbonded silanol groups. The higher ligand coverage results in improved inertness, chromatographic performance and stability.

Eshmuno® CPX media combines high aggregate removal efficiency in downstream purification linked to an outstanding high dynamic binding capacity, utilizing the 50 μm Eshmuno® base bead technology and EMD Millipore’s proprietary tentacle…

The EXP® Pre-Column Filter is ideal for protecting small-particle UHPLC columns at extreme pressures. Such techniques analyze samples in the most demanding applications, which can decrease the life of these expensive columns. EXP® Pre-Column Filters help extend that life and protect your column investment without sacrificing performance. Free-Turn® architecture allows the user to change cartridges by hand without breaking flui…

The EXP® Guard Column cartridge system is rated to 15,000 psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP® Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn¨ architecture allows the user to change cartridges by hand without breaking fluid connections…

The EXP® Stem Filter features a choice of frit porosities integrated with our patented auto-adjusting stem for repeated ZDV connections with any 10-32 port. The entire filter stem and reusable holder are only slightly larger than a standard HPLC fitting. This slim architecture allows it to easily fit into crowded instrument compartments, tightly spaced injection ports, and anywhere else you need an extra level of protection ag…

OPTI-GUARD® 1mm Guard Columns set 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® requ…
