Summary

Scientists were not immune to the home baking trends that grew out of a year of self-isolation and working from home. A creative application of soda bread as scaffolding for tissue engineering produced some exciting results and highlights the value of keeping it simple.

Sterlitech is an innovator in the development of bench-scale cross flow test cells for membrane development, studies, and small scale processing applications. But what does that actually mean?

Pre-Conditioning, Use, and Preservation

What is membrane preconditioning and why is it recommended to precondition new flat sheet or spiral wound membranes prior to use?

Membrane preconditioning is a filtration step using deionized water as feed solution and is typically performed at a pressure equal to or higher than the anticipated testing pressure. During this process membrane pores are wetted and the membrane structure may go through compaction or swelling, affecting both the permeate flux and the rejection values. Preconditioning will help ensure that the membrane performs according to the specs provided by the manufacturer.
