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

When tightened by hand, the EXP® 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). The EXP®® Stem Filter is the ultimate low-impact protection for EXP®ensive UHPLC and MS equipment, assuring trouble-free performance so you can concentrate on the data, not troubleshooting.

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 against clogging and contamination.
