How often do you change your tubing in the pumps? I know that in teh lab we have to change our tubes at a precribed interval to ensure accurate pumping. We also see degraded pumping when the tubing is left clamped in the pump.

What are your experiences?

Thanks

I haven't changed the tubing, it's norprene and considering the pumps are used for less than 20 minutes a day I figure I have a considerable period of time before I need to even concern myself with it. I have several feet of the tubing on hand should it become an issue. Considering I use EI dosing, some error is fine anyway. It's a valid point, but at 3rpm there isn't exactly a lot of wear and tear either.
