I am using Transwell plate, diameter 6.5 mm insert, 0.4 µm pore, Polyester Membrane Inserts Polystyrene plate from Coring (Cat#3470) for drug permeability experiments. It has been out of stock since July because of unexpected spike in demand. Vendors are still unable to provide this item. That is why I am searching for the substitute of Coring (Cat#3470). If you have used transwell plate other than Corning for the permeability experiment, please share your thoughts. Could you please share if you have any references?
Have you tried these inserts? They are still in stock.
