Does anyone know how to disassemble a P-1 peristaltic pump from Pharmacia/Amersham/GE? We have a couple that need simple repairs to either a switch or a rheostat on the control panel, but I'm stumped as to how to actually get the damn thing open. If you've succeeded in doing this, I'd be grateful for any pointers. Pat --------------------------------------------------------------------------------------- Patrick J. Loll, Ph. D.
