New Crossflow Cell Assemblies from Sterlitech



Sterlitech now offers five different bench-scale crossflow cell assemblies to meet your specific, experimental needs. In addition to the rectangular crossflow cells, the Innovator CF016, the Explorer CF042, and the Developer Sepa, the two, new circular designed CF047 and CF090 cells are rounding out the product line. Both have a 316 stainless steel cell body,  maximum operating pressure of 69 bar (1000 psig) at 22°C, (71.6°F), and a maximum operating temperature of 150°C (302°F). Available in two sizes, the cells will assist researchers in scaling up to larger membranes.


Pioneer CF047

Active membrane area: 14.6 sq. cm


Researcher CF090

Active membrane area: 53.0 sq. cm

The Pioneer and Researcher cells can evaluate flat sheet membranes for a variety of applications. They simulate the flow dynamics of larger, commercially available spiral membrane elements through the operator varying the operating conditions and fluid dynamics over broad ranges.

Typical applications for our crossflow product line have been desalination, ultrafiltration, and testing of lab scale fabricated membranes. Other uses include biological and biopharmaceutical processing, concentration of fruit juices and extracts, food and beverage processing, purification of rinse water in electroplating tanks, and municipal or industrial water and wastewater purification.

Advantages of a circular cell assembly:

  • 316 stainless steel for chemical compatibility 

  • Most membranes are available in circular coupons 

  • Circular cell integrates with typical circular vacuum filter holders to provide seamless testing capability for vacuum-prepared membranes

  • Designed for reverse osmosis, nanofiltration, ultrafiltration and microfiltration applications

  • New design provides fast and accurate performance data with minimal membrane material, expense, and time

The compact design minimizes cell footprint on lab bench space without compromising the broad scope of applications and operating conditions that the CF047 and CF090 can accommodate. Like each of our assemblies, they are able to be fitted into existing Sterlitech crossflow filtration skids and systems. More details on how to get started fitting the test cell into a full crossflow system available below.
