Dear all, sorry for the off-topic question. I want to buy a simple peristaltic pump to apply larger sample volumes (300-500 mL) to simple affinity columns (desired flow-rates: 2-8 mL/min). I was wondering whether the (good?)-old Pharmacia/GE P1 pump still represents the best system engineers have come up with so far. It also wouldn't hurt if the pump would beat the GE prize-tag of about $ 1,800.
Best, Michael
