> it is not cheap - probably $500 When we purchased the pump, it was below $300 (a year ago). Replacement took ~4 hours, but you must like doing it. You'll have to disassemble almost entire pump module, so make pictures of each step and mark tubings ends with labels.

They can come to your lab to do the job for you but I do not know how much it is per hour. This team is called labcrew and they are very good. > > I would call them and try to arrange with them. > > Make sure you have your solutions elevated above the pump. Even though it is a pump you need to help it. Also do not use viscous solutions with it. (I do not use glycerol because of the pump). Finally clean it up with 20% ethanol after each use to avoid mold. > > On Thu, Jul 12, 2012 at 5:09 PM, Peter Hsu <[log in to unmask]> wrote: > Hi all, > > We've got an old Akta prime that I think is on the verge of kicking it. Hearing some high pitched sounds coming from the pump when we're running it. Line A seems clogged and makes a thudding noise when we try to do a pump wash through that line. Does anyone have any experience w/fixing one/replacing the pump? Or any idea how much it's going to set us back to get it fixed? > > Sorry for the off topic question/thanks in advance for any thoughts and ideas. > > Peter >
