Sorry, it was the polyseal caps specifically. Why was polypropylene caps determined to be better than the polyseal, especially for the smaller sized vials?




Budget. We had lots of 2 dram vials and polypro stoppers . . . and the stoppers have held up great over the past 20 years.
To purchase new vials and polyseal caps for the size of our fluid collection would have been extremely cost prohibitive.
