Optimize Technologies EXP2 Replacement Stems, 0.17µL, 3.0µm EXP, SCX, 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
Optimize Technologies EXP Pre-Column Filter Cartridge, 0.5µm, 5pk
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 fluid connections on the holder inlet/outlet. EXP™ Pre-Column Filter holders are available with Titanium Hybrid ferrules for easy direct connection to any 10-32 port. The filter holder comes as a complete package including fittings to provide repeated zero-dead volume column connections. Use with holder part number 15-04-03837.
Optimize Technologies EXP Trap Cartridge, 1mm x 5mm, 3.0µm EXP, 3.0µm EXP, SAX, 3pk
The Hand-Tight EXP™ Trap Column is rated to 20,000+ psi. This unique design connects directly to any injection valve (with 10-32 threads) or in-line with 1/16” tubing for unparalleled convenience and efficiency. The EXP™ System enables chemists to quickly remove detergents or salts which can affect the ionization process in MS work. This trapping technique can concentrate the sample directly on-line, allowing for increased recovery of precious sample material compared to off-line techniques. Free-Turn™ architecture allows users to change cartridges by hand without breaking fluid connections on the holder inlet/outlet. The EXP™ Trap Column family now offers packed beds available in 2, 5, 10, 15, 20 and 30mm lengths with diameters ranging from 1-4.6mm and bed volumes from 1.6-600µL. Please contact your representative directly if you're interested in a length other than 5mm.
