Uniliner™ Liners for 1/4-Inch Packed Injection Port Conversion

By Restek
Uniliner™ Liners for 1/4-Inch Packed Injection Port Conversion
  • Reduces solvent tailing.
  • Versatile--0.53mm 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 the direct injection mode.
  • Available in various designs.

*DI = direct injection, OC = on-column injection

Note: a Uniliner® liner must be used with a Uniliner Liner Adaptor (Cat.No. 226- 20310 or 226-20311) for 1/4" injection ports. Remember to include a liner adaptor when ordering a Uniliner liner, unless you are purchasing replacement Uniliner liners.

On-column injections can be performed only with 0.53mm ID columns because 26-gauge needles do not fit into the bore of 0.32mm ID columns, not into the Unliner liner taper.

5mm Uniliner liners fit into the 1/4" Uniliner Liner Adaptor, which fits into a 1/4" injection port. The Uniliner liner can be inserted in one direction for direct injections or inverted for on-column injections. Because the 1/4" injection port ferrule seals against the metal liner adaptor surface, it is virtually impossible to crack the glass Uniliner liner during installation.
