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 PTFE-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.

What size membrane does the HP4750 Stirred Cell use?

Q. What size membrane does the HP4750 Stirred Cell use?

A. Any 47-50mm membrane disc can be used.

What material is the HP4750 Stirred Cell made out of?

Q. What material is the HP4750 Stirred Cell made out of?

A. The cell itself is constructed of 316 stainless steel and utilizes a PTFE coated stirrer for chemical resistance.

What type of stir plate do you recommend for use with the HP4750 Stirred Cell?

Q. What type of stir plate do you recommend for use with the HP4750 Stirred Cell?

A. Any conventional magnetic stirrer will work.

What do I do to release the pressure on the HP4750 Stirred Cell?

Q. What do I do to release the pressure on the HP4750 Stirred Cell?

A. You will need a tee that has a needle valve so that you can slowly release the pressure when ready to lower the pressure. You will need a needle valve rated for at least 1000 psi with a ¼' NPT.

Can I cut a membrane for use in the HP4750?

Q. Can I cut a membrane for use in the HP4750?

A. Yes, use the metal membrane support as a guide for cutting a disc.
