-Inch Packed Injection Port Conversion
• Reduces solvent tailing.
• Versatile—0.53 mm ID version can be used in the direct (DI) or on-column (OC)
injection mode.
• Incorporates a gentle taper that seals the column and reduces dead volume in direct
injection mode.
• Available in various designs.
On-column injections can be performed only with 0.53 mm ID columns becaus
26-gauge needles do not fit into the bore of 0.32 mm ID columns, or into the Unliner
liner taper.
5 mm Uniliner® liners fit into the
1
/
4
-inch
Uniliner® Liner Adaptor, which fits into a
1
/
4
-inch injection port. The Uniliner® liner
can be inserted in one direction for direct
injections or inverted for on-column injections.
Because the
1
/
4
-inch injection port ferrule seals
against the metal liner adaptor surface, it is
virtually impossible to crack the glass Uniliner®
liner during installation.

liner, unless you are purchasing replacement Uniliner liners.
