Sample Injector VI・MI Series

Manual injectors in a new design, offering high sample repeatability and a convenient injection handle, in an easy to install, easy to maintain package.

Sample Injector V Series

High Performance Manual Injectors Offering high sample repeatability, a convenient injection handle, in an easy to install, easy to maintain package. The PEEK rotor seal provides unparalleled solvent resistance.

Features
  • 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.
