Hi all, here in Chile we are facing a brutal shortage of consumables of Merck-Sigma-Millipore, specially after the fusion of Merck with Sigma and the pandemia, anyway the thing is that ultra filters from Millipore are taking 6 to 8 months to reach us! and we base many of our projects in ultrafiltration. The question es: do you know of a reliable (trsutable) substitutes for Amicon ultrafilters? Gracias
A search for "Ultrafiltration Suppliers" yields numerous other manufacturers. One summary version is here:

The issue is more likely to be one of logistics in your case. If the established provider (Millipore) is having difficulty getting their products to you in a timely fashion, other suppliers may not have any better results.
However, you might find one of the alternative producers closer to home or with available stock nearby
Best regards,
Steven
