The EXP®2 Stem Trap (Nano Flow) is a compact packed floating-stem trapping system for nano-flow applications. It uses the reusable EXP2 Stem Holder (15-02-03996).
Two product choices are available:
When assembled with the EXP2 Stem Holder, the packed floating stem connects directly to a 10-32 port and automatically adjusts to provide a zero-dead-volume connection.
Five bed-volume configurations are available from 0.17 uL to 2.6 uL. Packing Material and Phase availability depends on the selected configuration.
EXP2 Stem Trap hardware seals to 8,700+ psi when hand-tightened and 20,000+ psi (1,400+ bar) when wrench-tightened. Configuration-specific pressure limits apply; operate within the limit of the selected configuration. The selectable Peptide configuration is limited to 6,000 psi.
Custom packing/configuration is available by request rather than as a standard self-service purchase.
EXP2 Stem Trap uses the reusable EXP2 Stem Holder 15-02-03996. The Stem Trap Kit includes the holder, fittings, and three packed stems; Replacement Stems 3/pk are for use with an existing EXP2 Stem Holder.
When assembled with the EXP2 Stem Holder, the packed floating stem connects directly to a 10-32 port and automatically adjusts to provide a zero-dead-volume connection.
Packing Material and Phase availability depends on the selected configuration. The product selector controls the configurations currently available for standard online ordering.
