2 Overview

2.1 Unit Description

The SRD is a modern high-quality instrument designed for HPLC analysis, especially as
part of the UltiMate 3000 system. The SRD provides a secure location for installation of
the solvent reservoirs and, when mounted on top of the UltiMate 3000 system, saves
valuable bench space.
The SRD includes a reservoir tray, solvent reservoirs, and appropriate tubing. The integrated
analytical vacuum degasser continuously degasses solvents through special polymer
membranes that are permeable to gas, but not to liquids. Degassing solvents guarantees
reproducibility and reduces pulsation in the connected pump.
All parts in the flow path are made of amorphous fluoropolymer (AF), PEEK, FEP, and
ETFE/ECTFE (filter frit in the solvent supply line filter: stainless steel, PEEK, or titanium,
depending on the pump type) to provide optimum resistance to the most commonly used
HPLC solvents and buffer solutions.

2.2 SRD Configurations

The SRD is available in the following configurations:
SRD Description
