HPD™ Accurate high-pressure flow dispenser

The HPD™ is a world class dispenser resisting a high working pressure up to 300 bar. It was originally designed for SPE solvent delivery in online LC systems, but other applications are easy to imagine. What about pre-column reagent addition for online derivatization and post-column reagent addition for detection enhancement.

This world class dispenser delivers your sample without backpressure dependency up to 300 bar.

Why choose the HPD™?

Accurate volume delivery

Backpressure up to 300 bar

Solvent pre-mixing

Accurate flowrate

Sample delivery at high pressure

Traditional volumetric dispensers are designed for pipetting reagents or samples into vials or wells at ambient pressure or a few bar at most. Online volumetric reagent delivery however, may require the ability to introduce reagents into a system with a high working pressure. The HPD™ can accurately dispense without backpressure dependency up to 300 bar.

Key features
