This particular offering from Nalge Nunc combines robust construction with an integrated barcoding system, aiming to streamline laboratory workflows and minimize the risk of sample mix-ups, a costly problem in any research environment.
My journey into the world of cryogenic vials began with a pressing need to establish a reliable long-term storage solution for sensitive DNA samples collected during a wildlife conservation project. Traditional labeling methods proved inadequate, leading to errors and potentially compromising years of research. I needed a system that could not only withstand the rigors of cryogenic storage but also offer seamless integration with our existing database and sample management software.
The Nalge Nunc Cryogenic Vials with Bar Code arrived securely packaged, a testament to the Nalge Nunc’s commitment to quality. Immediately, I noted the clean, professional design and the reassuringly sturdy feel of the vials. The bar codes were crisp and clear, easily scanned by our existing equipment, and the self-standing base added a touch of practicality that I appreciated.
Compared to some generic cryogenic vials I’d previously experimented with, these were leagues ahead. Those other vials often suffered from inconsistent sealing, leading to concerns about sample integrity. Also, their flimsy construction never inspired confidence for long-term cryo storage. The Nalge Nunc vials promised something more: reliability, traceability, and peace of mind.
My initial impression was one of cautious optimism. While the vials appeared to be well-made and met my basic requirements, the true test would lie in their performance under extreme conditions and their long-term durability. The price point of $719.99 for a case of 250 is a significant investment, so I was keen to ensure that the vials lived up to their promise of superior performance and reliability.
Real-World Testing: Putting Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-0050, Case of 250 to the Test
First Use Experience
My initial testing ground was a university research lab, simulating the extreme conditions of long-term sample storage. We subjected the vials to a series of rigorous tests, including repeated freeze-thaw cycles and prolonged immersion in vapor-phase liquid nitrogen. The primary focus was on assessing the integrity of the seals and the readability of the bar codes after exposure to cryogenic temperatures.
The vials performed admirably, maintaining a secure seal throughout the freeze-thaw cycles and exhibiting no signs of cracking or degradation. Even after prolonged exposure to liquid nitrogen vapor, the bar codes remained legible, allowing for seamless sample tracking. The ease of use was also noteworthy; the large inner diameter facilitated easy filling, and the external threads allowed for single-handed aseptic technique, minimizing the risk of contamination.
Extended Use & Reliability
After several months of continuous use, the Nalge Nunc Cryogenic Vials continued to impress. We had encountered no instances of leakage or compromised sample integrity, even with vials stored at -196°C. The barcoding system proved invaluable for tracking thousands of samples across multiple research projects, significantly reducing the risk of errors and streamlining our inventory management.
There were minimal signs of wear and tear, with the vials maintaining their structural integrity and the bar codes remaining legible. Regular maintenance involved simply cleaning the vials with a mild disinfectant and ensuring that the threads were free of debris, a straightforward process that took minimal time and effort. Comparing these vials to our previous experiences with generic alternatives, the difference was stark. The Nalge Nunc vials offered superior reliability, durability, and ease of use, making them a worthwhile investment for any research lab or biobank.
Breaking Down the Features of Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-0050, Case of 250
Specifications
The Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-0050 boast several key specifications that contribute to their superior performance. These vials have a capacity of 5mL, which is a standard volume for many cryopreservation applications. Their outer dimensions are 13.5 x 89.4mm, a size that is ideal for fitting into standard cryo storage boxes and racks.
The vials are constructed from polypropylene, a durable and chemically resistant material, with polyethylene closures. These closures, combined with a sealing ring, ensure a secure and leak-proof seal, essential for maintaining sample integrity. Each vial features a unique Code 128-numeric bar code, printed in black on a white background. The bar codes are guaranteed to have no duplicate numbers, and are resistant to a range of common laboratory chemicals, including isopropyl alcohol, DMSO, and bleach.
Performance & Functionality
The primary function of these vials is to safely store biological samples at cryogenic temperatures while ensuring accurate traceability. The Nalge Nunc Cryogenic Vials excel at this task, providing a reliable and secure storage solution. The barcoding system streamlines sample tracking, eliminating the need for manual labeling and reducing the risk of errors.
The self-standing design adds to their usability, allowing for easy filling and handling. One minor weakness is that the polypropylene construction, while durable, is not suitable for autoclaving; however, the vials are pre-sterilized by radiation, mitigating the need for autoclaving in most applications. Overall, the Nalge Nunc Cryogenic Vials meet and exceed expectations, providing a high level of performance and functionality.
Design & Ergonomics
The design of the Nalge Nunc Cryogenic Vials is both functional and ergonomic. The vials are lightweight and easy to handle, even when wearing cryogenic gloves. The external threads and deep-skirted closures allow for single-handed aseptic technique, minimizing the risk of contamination.
