1. INTRODUCTION
The HP4750 Stirred Cell is a high-pressure, chemically resistant stirred cell that performs
a wide variety of membrane separations. With a maximum pressure rating of 1000 psig
(69 bar), the HP4750 Stirred Cell is ideally suited for reverse osmosis (RO) filtration,
nanofiltration (NF), ultrafiltration (UF), and microfiltration (MF) separations. Stainless steel
(316L) construction and chemically resistant components make the HP4750 Stirred Cell an
ideal choice to filter aqueous and non-aqueous solutions.
Table 1 outlines the operational parameters and technical specifications of the HP4750
Cell.
Prior to operating or servicing this device, this manual must be read and understood.
