Let’s Dive into Nalge Nunc Cryogenic Vial Closure Color Coders, Polystyrene, NALGENE 5045-0003, Pack of 100
The Nalge Nunc Cryogenic Vial Closure Color Coders, Polystyrene, NALGENE 5045-0003, Pack of 100 are small, seemingly insignificant discs, but they play a crucial role in organized sample management within cryogenics. These color coders, manufactured by NALGENE, fit snugly into the top of cryogenic vial closures, providing a quick and easy visual identification system. This seemingly simple product addresses a very real need.
My work often involves storing and retrieving hundreds of samples in cryogenic conditions. Without a clear identification system, finding the right sample in a timely manner can feel like searching for a needle in a haystack, costing valuable time and risking sample integrity. These color coders promised a solution to streamline this process, a promise I was eager to test.
The Nalge Nunc Cryogenic Vial Closure Color Coders arrived in a simple, resealable plastic bag, containing 100 blue polystyrene discs. My initial impression was that the discs were surprisingly lightweight. The material felt smooth and uniform, and the color was consistent throughout the batch.
Having used simple labeling tape on vials previously, which tends to become brittle and fall off in extreme cold, I was looking for something far more durable and reliable. While other color-coding systems exist, such as pre-printed labels or markers, I chose the Nalge Nunc option for its simplicity, ease of application, and the promise of resilience in cryogenic environments. I was optimistic but also cautiously aware that such a simple solution might have limitations in real-world application.
Real-World Testing: Putting Nalge Nunc Cryogenic Vial Closure Color Coders, Polystyrene, NALGENE 5045-0003, Pack of 100 to the Test
First Use Experience
My first experience with the Nalge Nunc Cryogenic Vial Closure Color Coders involved organizing a new batch of cell culture samples for long-term storage. I applied the blue coders to a series of vials containing a specific cell line. The discs snapped easily into the designated space within the vial closure.
The environment in the cryo-lab is typically very cold and dry. Handling small objects with gloved hands can be challenging. The discs, however, were easy to grip and manipulate, even with thick cryogenic gloves.
Initially, I was impressed by how quickly I could visually identify vials assigned to the same cell line using these color coders. The system worked immediately. I found that having a consistent and robust color-coding system increased my efficiency in the lab.
Extended Use & Reliability
After several weeks of use, including multiple freeze-thaw cycles, the Nalge Nunc Cryogenic Vial Closure Color Coders have held up remarkably well. They showed no signs of cracking or discoloration. The discs remained firmly in place within the vial closures.
During routine checks of the liquid nitrogen freezers, I noticed no signs of degradation or detachment, even in the vials submerged in liquid nitrogen. The discs have proven resistant to the extreme temperatures and harsh conditions within the freezers.
The Nalge Nunc Cryogenic Vial Closure Color Coders outperform labeling tape in terms of durability and longevity in cryogenic conditions. In comparison to previous solutions that degraded and peeled off, these coders provide a reliable and long-lasting visual identifier for cryogenic vials. The robust nature and straightforward application of these color coders have exceeded my initial expectations.
Breaking Down the Features of Nalge Nunc Cryogenic Vial Closure Color Coders, Polystyrene, NALGENE 5045-0003, Pack of 100
Specifications
- Material: Polystyrene – Chosen for its durability and resistance to cryogenic temperatures.
- Color: Blue – Offers a readily identifiable visual cue within a diverse sample collection.
- Compatibility: Designed for NALGENE cryogenic vial closures (1.2, 2.0, and 5.0 mL) – Ensures a snug and secure fit, preventing accidental detachment.
- Quantity: Pack of 100 – A sufficient quantity for organizing and managing a substantial number of samples.
- Design: Disc with cut-out top – Allows for easy handling with forceps and facilitates writing on top of the vial.
These specifications are critical because they directly impact the functionality and reliability of the color-coding system. The polystyrene construction guarantees durability in extreme cold, while the precise fit in NALGENE vials prevents detachment. The cut-out top offers an important feature for ease of handling with lab tools and aids in direct vial identification.
Performance & Functionality
The Nalge Nunc Cryogenic Vial Closure Color Coders perform their job exceedingly well, providing a simple yet effective method for quickly identifying vials. The color coding system reduces the time required to locate specific samples, minimizing the exposure time of frozen samples to ambient temperatures.
One minor weakness is the limited color selection – a greater range of colors would allow for more granular categorization. Despite this, the blue coders effectively meet the core need for visual identification. The color coders exceed expectations in both ease of use and performance within a cryogenic environment.
Design & Ergonomics
The build quality is excellent, with the polystyrene discs being uniform in shape and size, ensuring a consistent fit within the vial closures. The lightweight design ensures that the coders do not add any significant weight to the vials, maintaining easy handling.
The cut-out top provides easy access to the vial closure, even when wearing bulky cryogenic gloves. There is no learning curve associated with this product; it’s as simple as popping the disc into place. The product’s design perfectly addresses the need for easy identification and manipulation in a lab setting.
Durability & Maintenance
The Nalge Nunc Cryogenic Vial Closure Color Coders are designed to last the duration of the sample storage, with no signs of wear and tear observed even after prolonged exposure to cryogenic temperatures. These color coders require virtually no maintenance.
If they become contaminated, they can be easily wiped clean with standard laboratory disinfectants. The simple and robust design ensures the longevity and reliability of these color coders, proving their value for long-term sample management.
Accessories and Customization Options
No accessories are included with the Nalge Nunc Cryogenic Vial Closure Color Coders as they are self-contained. Customization is limited to writing on the top of the vial, which is made easier by the flat surface of the coder.
While not a traditional accessory, users may benefit from forceps designed for cryogenic use to further facilitate handling of the vials and the color coders. The simplicity of the design minimizes the need for additional accessories. The focus remains on reliable and easy identification within cryogenic storage.
