Real-World Testing: Putting Nalge Nunc SYSTEM 100 Cryogenic Vials, NALGENE 5000-1012, Case of 500 to the Test

First Use Experience

My initial deployment of the Nalge Nunc SYSTEM 100 Cryogenic Vials, NALGENE 5000-1012, Case of 500 involved transferring various biological samples for long-term storage. I meticulously filled each vial to the indicated 1.0 mL capacity, ensuring the fill line was respected for optimal sealing. The externally threaded design proved invaluable for maintaining aseptic technique, minimizing contamination risks during the crucial sample handling phase.

These vials were immediately placed into mechanical freezers operating at -80°C and subsequently transferred into liquid nitrogen vapor-phase dewars for extended preservation. During this process, and throughout numerous freeze-thaw cycles, not a single leak was detected. The silicone gasketed polypropylene closures performed exactly as advertised, providing a secure, leak-proof seal even under extreme temperature differentials.

Ease of use was exceptional. The self-standing base of the vials allowed for easy manipulation on the benchtop, and the external threads prevented any snagging or interference with the sample when opening or closing. The clear markings, including graduations and a fill line, were easily visible and accurate, aiding in precise sample volume management.

The only minor surprise was the sheer density these vials allowed when used with compatible cryoboxes. I found I could store significantly more samples in the same freezer space compared to my previous methods. This efficiency was a welcome revelation, directly addressing one of my primary procurement goals.

Extended Use & Reliability

After months of continuous use, the Nalge Nunc SYSTEM 100 Cryogenic Vials, NALGENE 5000-1012, Case of 500 have proven to be exceptionally reliable.
