We get ours at Walmart. The clear plastic wide tape that is sold as
packaging tape works as well as the yellow 3M stuff and costs about
$3 per roll. The stuff we get is made by Manco Inc. and has green
labeling inside the roll. We tried a cheaper source (brand name
Sekisui Ta Ind.) and it won't hold. We just tested the ability of
tape to seal on the top of a flask against a high urea solution.
