Dear all, for our perfusion chromatography workstation BioCAD 700E from Applied (PerSeptive) Biosystems we are looking for a proportioning valve. I would be glad if someone has an old system out of use we can get this part from or if someone has a suggestion for an cheap alternative. Thank you in advance!
