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.
