Maintenance is simple: a quick rinse with soap and water is all it takes to keep them clean. These caps outperform every makeshift solution I’ve used in the past, providing superior reliability and peace of mind.
Compared to using standard stoppers or parafilm, the Nalge Nunc caps provide a far superior seal and eliminate the risk of accidental contamination.
