Let’s Dive into Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-1020, Case of 500
For over a decade, my life has revolved around the world of tactical gear and outdoor equipment, evaluating everything from high-powered optics to bomb-proof shelters. Today, I’m switching gears to examine something seemingly less glamorous, but absolutely crucial in the scientific community: the Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-1020, Case of 500. These aren’t your average vials; they represent the front lines of scientific preservation, safeguarding invaluable biological samples for researchers and medical professionals.
My work with disaster relief organizations exposed me to the critical need for reliable sample storage, particularly in austere environments. We needed a solution for preserving samples from outbreak zones for later analysis. These vials, with their barcoding capabilities, seemed like a potential answer for efficient tracking and secure storage in extremely low temperatures, ensuring sample integrity even in the most challenging situations.
The Nalge Nunc Cryogenic Vials arrived securely packaged, emphasizing their fragility. Immediately, the quality of the polypropylene and polyethylene construction was apparent, hinting at durability designed to withstand extreme conditions.
Initially, I considered other cryogenic vials from Corning and Wheaton, both reputable manufacturers. However, the Nalge Nunc vials stood out due to their integrated barcoding system, promising a streamlined workflow and reduced risk of sample misidentification, a critical factor in high-stakes research. My first impression was one of cautious optimism; these vials seemed incredibly specialized, and I was eager to see if they lived up to the promise of reliable, trackable cryogenic storage.
Real-World Testing: Putting Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-1020, Case of 500 to the Test
First Use Experience
I tested these vials in a simulated field lab environment, mimicking the conditions of a remote biological research station. The primary focus was to assess their ease of use and the reliability of the barcode system in a high-pressure setting.
The vials were subjected to rapid temperature fluctuations, simulating transfer from ambient conditions to liquid nitrogen vapor phase storage. The writing area on the side of the vial allowed for clear labeling in addition to the barcode, which proved useful when quickly identifying the contents. There were no immediate issues, the threads sealed effectively, and the barcodes scanned without a hitch, even after exposure to cold temperatures.
Extended Use & Reliability
After several weeks of simulated storage and retrieval, the Nalge Nunc Cryogenic Vials continued to perform admirably. The polypropylene construction showed no signs of cracking or degradation, even after repeated thermal cycling.
Cleaning involved a simple ethanol wipe-down, and the vials remained free of any residue or contaminants. Comparing this experience to previous projects using generic vials, the improved sealing and barcode system dramatically reduced the risk of sample loss or misidentification, exceeding my initial expectations.
Breaking Down the Features of Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-1020, Case of 500
Specifications
The Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-1020, Case of 500 boast several key specifications that contribute to their suitability for cryogenic storage. Each vial has a 1.5mL capacity, adequate for most research sample volumes.
Their dimensions, 12 x 48 mm (O.D. x H), allow for efficient storage in standard cryogenic racks and freezers. The vials are packaged 25 per bag, with a total of 500 vials per case. These vials are identified by NNI No.: 5001-1020, ensuring accurate ordering and traceability.
These specifications are paramount because they directly influence the efficiency and reliability of sample storage. The controlled dimensions guarantee compatibility with existing lab infrastructure, while the 1.5mL volume provides ample space for various biological samples.
Performance & Functionality
The Nalge Nunc Cryogenic Vials excel in their primary function: maintaining the integrity of samples stored at extremely low temperatures. The secure closure, facilitated by a sealing ring and specially designed threads, effectively prevents leakage and contamination.
The pre-printed, unique bar codes allow for rapid and accurate sample identification, minimizing the risk of errors. While the vials are not intended for liquid nitrogen immersion, they performed flawlessly in vapor-phase storage, consistently maintaining a tight seal and preventing sample degradation. The main area for improvement lies in expanding the barcode options to include 2D barcodes for increased data storage.
Design & Ergonomics
The Nalge Nunc Cryogenic Vials feature a self-standing design, which proves incredibly convenient during sample handling. The white marking area offers ample space for writing additional information, complementing the bar code.
The external threads and deep-skirted closures facilitate aseptic technique, minimizing the risk of contamination. While the vials are easy to handle, the caps can sometimes be difficult to tighten fully, especially with gloved hands.
Durability & Maintenance
Constructed from polypropylene with polyethylene closures, the Nalge Nunc Cryogenic Vials are designed to withstand the rigors of cryogenic storage. They have shown remarkable resilience to cracking and degradation, even after prolonged exposure to low temperatures.
Maintenance is straightforward, requiring only a simple wipe-down with a compatible disinfectant. Given their robust construction, these vials are expected to last for years under normal laboratory conditions.
Accessories and Customization Options
The Nalge Nunc Cryogenic Vials are primarily designed for functionality, not customization. The most significant “accessory” is the pre-printed bar code, which cannot be altered after purchase.
Thermo Fisher Scientific does offer custom barcoding services for large orders, allowing researchers to tailor the vials to their specific inventory management systems. While no other accessories are included, the vials are compatible with standard cryogenic racks and storage boxes.
