Even after being filled and emptied upwards of 30 times, the thermoset caps retain their snug fit, and the fluoropolymer resin lining shows no signs of degradation or compromise. I have yet to experience any leaks, which is a critical benchmark for laboratory storage.
Compared to some of the cheaper, generic glass bottles I’ve used in the past, which often developed micro-cracks or suffered from cap shrinkage over time, these Qorpak units are in a different league. Those cheaper alternatives would often require replacement after just a year or two of heavy use; these, however, show no such signs of premature wear. They are also straightforward to clean; a simple soak in a cleaning solution followed by a thorough rinse and air drying is all that’s typically needed.
