Real-World Testing: Putting Nalge Nunc SYSTEM 100 Cryogenic Vials, NALGENE 5000-1012, Case of 500 to the Test
First Use Experience
Our primary testing ground was the university’s cryo-preservation facility, where we maintain a bank of diverse biological samples stored in liquid nitrogen freezers. We filled a representative subset of the Nalge Nunc SYSTEM 100 Cryogenic Vials with varying microbial suspensions. These were then subjected to rapid freezing and subsequent immersion in liquid nitrogen (-196°C).
The vials performed flawlessly in the initial freezing process, showing no signs of cracking or deformation. The external threads allowed for easy and secure capping, even with gloved hands. There were no leaks observed, even after direct immersion in liquid nitrogen.
Extended Use & Reliability
After six months of continuous cryogenic storage, a comprehensive viability assay was performed on the stored samples. The results were remarkable: cell viability remained consistently high, demonstrating the effectiveness of the Nalge Nunc SYSTEM 100 Cryogenic Vials in preserving biological material. Minimal degradation was observed.
The vials exhibited exceptional durability over the extended storage period. Periodic inspections revealed no signs of embrittlement or structural weakening, despite the repeated freeze-thaw cycles. The vial’s polypropylene construction proved resistant to the extreme temperature fluctuations.
Maintaining the vials was straightforward. A simple wash with mild detergent followed by autoclaving was sufficient for sterilization and reuse. The vials maintained their structural integrity even after repeated autoclaving cycles, far surpassing our expectations.
Compared to our previous experiences with cheaper vials from less reputable brands, the Nalge Nunc SYSTEM 100 Cryogenic Vials were a game-changer. Sample integrity was significantly improved, leading to more reliable and reproducible experimental results, justifying the initial investment.
