Optimize Technologies EXP2 Stem Filter Replacement Cartridge, 0.5 µm, 5pk
The EXP™2 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 slim architecture allows the product to easily fit into crowded instrument compartments, tightly-spaced injection ports and anywhere else an extra level of protection against clogging and contamination is necessary. The EXP™2 Stem Filter is an ideal solution to protect expensive UHPLC columns, injectors, autosamplers and MS electrospray tips without extra-column effects. When tightened by hand, the stem filter seals to 8,700+ psi. The reusable holder hardware also incorporates wrench flats to enable flawless sealing to 20,000+ psi (1,400+ bar). This product also incorporates the Optimize integral ferrule design so that the ferrule is fixed into the front end of the holder preventing frustration and wasted time searching for tiny lost ferrules. For use with EXP™2 Stem Holder only: part number 15-02-03996.
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 EXP2 Replacement Stems, 0.68µL, 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 Trap Cartridge, 3.0mm x 5mm, 3.0µm EXP, SCX, 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.
