Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-1020 Review

True Results from the Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-1020, Case of 500

As a seasoned outdoor and tactical gear specialist, I’ve seen gear for nearly every conceivable scenario. But handling biological samples in extreme conditions requires specialized equipment, and the Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-1020, Case of 500 immediately caught my eye. These vials promise reliability and traceability for critical samples stored in the harshest cryogenic environments.

My work increasingly involves field research in remote locations, requiring me to collect and preserve biological samples for later analysis. This meant transporting samples, often in liquid nitrogen dry shippers, over rough terrain and extended periods. The lack of a reliable, barcoded vial had been a major pain point, leading to misidentified samples and wasted effort. The Nalge Nunc vials offered a solution with their pre-printed barcodes and certified sterile design, features that promised to streamline my workflow and improve data integrity.

Unboxing the case of 500 was impressive, the vials were neatly arranged in bags of 25. My initial thought was that the plastic felt robust and the barcode printing was clear and sharp. The vial caps had a reassuringly tight seal, hinting at their ability to withstand cryogenic temperatures without leaking.

Compared to generic, non-barcoded cryogenic vials I’d used previously, the Nalge Nunc vials offer a significant advantage in sample tracking and organization. I had also considered Corning cryogenic vials, but the Nalge Nunc’s reputation for quality and the availability of pre-printed barcodes swayed my decision. My initial impression was one of cautious optimism. These vials looked promising, but the real test would be in the field, battling fluctuating temperatures and the rigors of transport.

Real-World Testing: Putting Nalge Nunc Cryogenic Vials with Bar Code, NALGENE 5001-1020, Case of 500 to the Test

First Use Experience

My first field test was during a wildlife survey in the Alaskan backcountry. I needed to collect tissue samples from various species for genetic analysis. Samples were stored in the Nalge Nunc Cryogenic Vials and immediately placed in a liquid nitrogen dry shipper.

The Alaskan environment presented immediate challenges: sub-freezing temperatures, snow, and the constant risk of spills. The vials performed admirably, maintaining their integrity even after repeated exposure to the cold. The external threads and deep-skirted closures facilitated easy, single-handed operation.

Using traditional vials, I often struggled with labeling in the field, especially with gloved hands. The pre-printed barcodes on the Nalge Nunc vials eliminated this issue, allowing me to quickly scan and log each sample without removing my gloves, a huge time-saver. After my first use, I noted that the barcodes remained legible even after being submerged in liquid nitrogen vapor.

Extended Use & Reliability

After several months of consistent use, the Nalge Nunc Cryogenic Vials have proven to be remarkably reliable. I have used them across a range of projects, from collecting water samples in the Atacama Desert to preserving insect specimens in the Amazon rainforest. The vials have consistently maintained their integrity and barcode readability.

Even after repeated freeze-thaw cycles, there has been no noticeable degradation in the plastic. The vials have held up surprisingly well to the physical demands of fieldwork.

Maintenance is straightforward: a simple rinse with distilled water and ethanol is usually sufficient. The vials have shown no signs of discoloration or staining, even after storing pigmented samples. Compared to my previous experiences with less robust vials, the Nalge Nunc Cryogenic Vials have been a significant improvement. They have reduced the risk of sample loss and contamination, and provided an unmatched level of traceability.

The numeric Code 128 barcode is printed in black on a white background for easy scanning and identification. Each vial is guaranteed to have a unique barcode, eliminating the risk of duplicate identifiers. The vials are also printed with human-readable information below the barcode for manual verification. The vials and closures are preassembled and radiation-sterilized, and certified sterile, noncytotoxic, and nonpyrogenic for safe use with biological samples.

These specifications are critical for ensuring sample integrity and efficient workflow. The 1.5 mL capacity is ideal for most biological samples, while the barcode system streamlines data collection and minimizes errors. The sterilization and non-cytotoxicity certifications are essential for maintaining the purity of sensitive samples.

Performance & Functionality

The Nalge Nunc Cryogenic Vials perform their primary function of sample storage exceptionally well. They reliably maintain sample integrity across a wide range of temperatures, from ambient to cryogenic.

The barcodes are consistently scannable, even after exposure to extreme conditions. A key strength is their resistance to common laboratory solvents. A minor weakness is that the vial cap can be difficult to tighten with thick gloves. Overall, the vials meet and exceed expectations for cryogenic storage.

Design & Ergonomics

The Nalge Nunc vials have a simple, yet effective design. The polypropylene construction makes them lightweight and durable.

The external threads and deep-skirted closure allow for easy, one-handed aseptic technique. The vials feature a white marking area, fill line, and graduations printed on the side. I find the large inner diameter facilitates convenient filling, and no special tools are required to use them.

Durability & Maintenance

Based on my experience, these vials are built to last. The polypropylene material is highly resistant to cracking and shattering.

Maintenance is minimal; a simple wash with a mild detergent and rinse with distilled water is all that’s needed. The vials are autoclavable, but radiation sterilization is standard.

Accessories and Customization Options

The Nalge Nunc Cryogenic Vials come preassembled and sterilized, ready for immediate use. While there are no specific customization options for the vials themselves, their standard size and design make them compatible with a wide range of cryogenic storage boxes and racks.
