The reusable holder EXP™2 Stem Traps and Stem Filters, is only slightly larger than a standard HPLC fitting. The new EXP™2 design incorporates an integral ferrule into the front-end of the holder - preventing the loss of tiny ferrules. Its slim architecture allows it to easily fit into crowded instrument compartments or to connect directly to tightly-spaced injection ports. The unique packed floating stem installs directly into any 10-32 port and automatically adjusts to provide a perfect zero-dead-volume connection. When tightened by hand, the EXP™2 Stem Holder seals to 8,700+ psi. All configurations incorporate wrench-flats to enable flawless sealing to 20,000+ psi (1,400+ bar). For use with EXP™2 Stem Filter Cartridges only: part numbers 15-04-04117 and 15-04-04119.
