Features of HP4750 Stirred Cell
  • Safe Operation: Volatile solutions can be processed safely because the Sterlitech™ HP4750 operates on standard sources of compressed air or inert gases (nitrogen, argon, etc.). This provides the user with a variable, safe and consistent supply of pressure to effect membrane separations.
  • High-Pressure Operation: Solutions with high levels of dissolved solids and high osmotic pressure can be separated with the Sterlitech™ HP4750. The cell is designed for safe operation to 1000 psig (69 bar).
  • Removable Stir Bar: Concentration polarization at the membrane surface is minimized by a Teflon*-coated magnetic stir bar mechanism. The stir bar can be driven by any standard stirring plate.
  • Accepts Standard Membrane Discs: Sterlitech™ HP4750 Stirred Cell accommodates any 47 to 50 mm diameter membrane disc.
  • Chemically Resistant Materials of Construction: 316L stainless steel construction makes the Sterlitech™ HP4750 resistant to most chemical degradation. Buna-N gaskets and O-rings are provided as standard with other optional materials available to meet operating requirements.
  • Unique Design: The cell top can easily be removed to fill the vessel with up to 300 mL of solution. The cell bottom is removable for quick membrane change-out. The top and bottom are secured to the vessel with mechanical couplings. This unique design enables low hold-up volume, down to as low as 1 mL, so valuable solutions are not wasted.
