Sterlitech Corporation Announces First Transparent Crossflow System

Sterlitech Corporation announces its newest model in the CF042 series: the CF042AC. This unique, transparent version allows users to visually monitor the filtration process in order to improve research and development discovery and permit the exploration of new applications. This innovative design is solely offered by one of the leading producers of bench scale filtration equipment.

“We’ve seen a number of inquiries from customers wanting to know if the acrylic cell can be used for a variety of operations ranging from the typical to the completely unique,” according to Mark Spatz, President of Sterlitech. Standard uses for crossflow cells include: Membrane Development Testing, Flat Sheet Membrane Quality Assurance, and RO to MF Separation and Purification. Mr. Spatz added, “Being able to actually see the filtration process makes monitoring and evaluation much easier.”
Feed solution enters the membrane cavity in the CF042AC, flowing tangentially across the membrane surface. A portion of the stream permeates the membrane and flows through the permeate carrier located on the underside of the top half of the cell, finally exiting through the outlet on the top of the cell into a user designated collection vessel. The concentrate stream, which contains the material rejected by the membrane, continues sweeping over the membrane, exiting via the concentrate outlet on the underside of the bottom half of the cell into a discharge vessel or back in to the feed vessel. A concentrate control valve on the low pressure side of the holder allows for complete user control over the flow of the solution.

The acrylic model joins the lineup of Sterlitech’s other CF042 cells made from Delrin, Teflon, and 316 Stainless Steel. Selecting the proper cell depends largely on the chemical compatibility of the sample and the pressure requirements for the application. Sterlitech representatives are available to answer any questions on the CF042AC and their entire catalog of products. In addition to the CF042, Sterlitech also carries the HP4750 and Sepa CF series of crossflow cells.
