ive looked around at
USplastic and
McMaster, and USplastic has better prices. are there any other places that sell this stuff @ low prices?
also, some-1 should find out what the difference is between the R-1000 (used for peristaltic pumps) and R-3603 (lab grade) formulations, becuase the 3603 is much cheaper than the R-1000 formulation, and looks to have the characteristics we're looking for.
