The use of PEEK material in the rotor seal gives this injector excellent solvent resistance. Resists deterioration even with alkaline solvent. (Option: Vespel).

The compact injection marker is built into the unit . Solvent resistance enhanced by the use of a teflon membrane lead line.

The VI-13 features completely inert connection matrials, and comes with a standard PEEK/Teflon syringe needle. Best for ionic materials and protein analysis.

The special bypass built into the valve absorbs the pressure shock generated during path switching, protecting the column from possible deterioration resulting from sudden high pressures.
