I'm looking for 2 syringe pumps that can both infuse and withdraw for a flow experiment. it is preferable if they are programmable. They should fit a 60CC syringe with tubing of 1/8" (3.175mm) in diameter. In the attachment I added a page out of the catalog. It doesn't have to be exactly that of course, just to get an idea of the preffered setup.
