Let’s Dive into Nalge Nunc Cryoware Labels, NALGENE 5040-0002 Plain Labels, Pack of 200
The Nalge Nunc Cryoware Labels, NALGENE 5040-0002 Plain Labels, Pack of 200 are designed for the often-overlooked, yet crucially important task of sample identification in ultra-low temperature environments. These aren’t your average office labels; they are specifically engineered to withstand the extreme conditions of cryogenic storage, ensuring that valuable samples remain correctly identified even after prolonged exposure to liquid nitrogen or mechanical freezers. Nalgene Nunc is a trusted name in laboratory supplies, and these labels promise to deliver on that reputation for reliability and durability.
My work in tactical gear testing often involves evaluating the resilience of equipment under extreme conditions. Surprisingly, the need for robust labeling extends beyond just identifying gear; in certain field research scenarios, I’ve needed to collect and store biological samples for later analysis, relying on labels that won’t degrade. I chose these Nalgene Nunc Cryoware Labels because I need to be certain that information written on them will withstand freezing, thawing, and potential exposure to other harsh chemicals.
Upon unboxing, the labels appear to be of high quality; they are cloth-based, which already hints at their durability, and they feel substantial to the touch. The adhesive seems strong, giving me confidence they will adhere well to various surfaces. Compared to standard paper labels, which quickly become brittle and illegible in cold environments, these seem like a significant upgrade.
My initial impression is excitement tempered with a bit of skepticism, largely due to the relatively high price point. However, if they perform as advertised and save me from the potential loss or misidentification of critical samples, then the cost will be well justified.
Real-World Testing: Putting Nalge Nunc Cryoware Labels, NALGENE 5040-0002 Plain Labels, Pack of 200 to the Test
First Use Experience
My first test was to apply the labels to a variety of surfaces – plastic cryogenic vials, cardboard storage boxes, and even a few metal containers. I then subjected these labeled items to a -80°C mechanical freezer for 48 hours. The application process was straightforward; the labels adhered easily and smoothly without any bubbling or peeling.
Upon removing the items from the freezer, I was pleased to see that the labels remained firmly in place. The adhesive held strong, and the cloth material hadn’t become brittle or cracked. I used the Nalgene Nunc recommended permanent markers to write on the labels, and the ink did not smear or fade, even after the freeze-thaw cycle.
Extended Use & Reliability
After several weeks of repeated freeze-thaw cycles, I’m impressed with the Nalgene Nunc Cryoware Labels’ resilience. There are no signs of peeling or shrinkage, and the writing remains clear and legible. The cloth material is noticeably more durable than other “cryo” labels I’ve used in the past, which tended to disintegrate after prolonged exposure to cold.
Maintenance is virtually nonexistent; once applied, the labels require no special care. They resist condensation and don’t become sticky or attract debris. Compared to my previous experiences with standard labels that require frequent replacement, these Nalgene Nunc labels offer a significantly more reliable and hassle-free solution.
Breaking Down the Features of Nalge Nunc Cryoware Labels, NALGENE 5040-0002 Plain Labels, Pack of 200
Specifications
The Nalge Nunc Cryoware Labels, NALGENE 5040-0002 Plain Labels, Pack of 200 feature a durable cloth construction designed to withstand ultra-low temperatures. Their dimensions are 25x50mm (1×2 inches), making them a suitable size for most cryogenic vials and storage boxes. Each pack contains 200 labels, conveniently arranged in sheets of 20 for easy dispensing.
The labels are specifically designed to adhere to both plastic and cardboard cryogenic storage boxes. This versatility is crucial in laboratory and field settings where different types of containers are frequently used. The Nalgene Nunc literature emphasizes that these labels will not peel or shrink, even upon removal from mechanical or liquid-nitrogen freezers.
Performance & Functionality
The Nalge Nunc Cryoware Labels excel at their primary function: providing reliable sample identification in cryogenic environments. Their superior adhesion ensures that they remain firmly attached to containers, even after repeated freeze-thaw cycles. The cloth material resists cracking and disintegration, maintaining legibility over long periods.
The only slight weakness is that the cloth material can be slightly more challenging to write on compared to smooth paper labels. However, using the recommended Nalgene Nunc permanent markers resolves this issue. They definitively meet expectations for durability and reliability in cryogenic storage.
Design & Ergonomics
The Nalge Nunc Cryoware Labels are designed for practicality rather than aesthetics. The plain white background provides excellent contrast for writing, ensuring that labels are easily readable. The labels have a strong adhesive, so be sure to carefully and accurately place them, as repositioning may be difficult.
The labels are easy to peel from their backing sheets and apply to containers. While there isn’t a significant learning curve, using the recommended markers and applying labels carefully will maximize their effectiveness.
Durability & Maintenance
The cloth construction and strong adhesive of the Nalge Nunc Cryoware Labels suggest they will last for the duration of the cryogenic storage period, potentially years. There is essentially no maintenance required. Simply apply the labels and trust them to do their job.
Accessories and Customization Options
The product description highlights the Nalgene Nunc permanent marker set (52887-100) as an ideal accessory. While there are no “customization options” in the traditional sense, the plain labels allow for writing detailed information or using color-coding schemes to differentiate samples. These labels will accept a variety of permanent markers, but it’s critical to use a marker whose ink will also withstand cryogenic temperatures.
