Let’s Dive into VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19
The VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19 might seem like an unassuming product at first glance, but for those working in labs, research facilities, or even specialized food storage, these labels are indispensable. Manufactured by Advantech Manufacturing, these white, dot-shaped labels are designed to withstand the extreme temperatures of cryogenic storage, ranging from -196 to +121 degrees Celsius. They offer a reliable way to identify samples, tubes, and other items that need to be preserved in ultra-low temperature environments, preventing costly mix-ups and ensuring data integrity.
I was in desperate need of reliable labeling solutions. Our field team collects samples in harsh environments, and those samples are often stored in liquid nitrogen for transport. I needed a label that could withstand the elements and the extreme cold without losing adhesion or becoming illegible.
My initial reaction to the VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19 was one of cautious optimism. The roll of 1000 labels looked professional and well-made. I was hopeful that these would be the answer to my labeling woes, but I reserved judgment until I could put them to the test.
Compared to standard adhesive labels or even some “freezer-safe” options I’ve used in the past, the VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19 appeared to be a significant step up in terms of durability. These seemed much better than masking tape and a sharpie. My first impression was that these were built to last.
Real-World Testing: Putting VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19 to the Test
First Use Experience
My first test involved applying the VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19 to several 15ml polypropylene tubes containing water samples collected from a high-altitude lake. These tubes were then submerged in liquid nitrogen for 24 hours. The plan was to assess the label’s adhesion and legibility after this extreme temperature shock.
The labels performed admirably in these harsh conditions. They remained firmly attached to the tubes without any peeling or curling. The ink from my marker (a permanent lab marker, of course) was still perfectly legible. There was no smearing or fading whatsoever.
The labels were easy to peel from the roll and apply to the tubes, even while wearing gloves. They adhered quickly and smoothly, with no need for excessive pressure. This ease of use was a welcome change from some of the less user-friendly labels I’ve struggled with in the past.
Extended Use & Reliability
After several weeks of use, the VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19 has consistently delivered reliable performance. Batches of samples have been frozen, thawed, and refrozen multiple times. The labels remain intact and legible.
I’ve noticed no signs of degradation or wear and tear on the labels themselves. The adhesive continues to hold strong. They seem resistant to common lab solvents and chemicals. This level of durability is crucial for long-term sample storage and data integrity.
Compared to my previous experiences with other labels that would often peel, fade, or become brittle in cryogenic conditions, the VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19 significantly outperforms them. This performance gives me confidence in the long-term reliability of these labels.
Breaking Down the Features of VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19
Specifications
The VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19 boasts several key specifications that contribute to its exceptional performance in cryogenic environments. These labels are white dots, each 19 mm in diameter. They are supplied on a 44 mm core, with 1000 labels per roll and one roll per case.
The most important specification is the temperature range: -196 to +121 degrees Celsius. This wide range ensures that the labels can withstand both liquid nitrogen storage and autoclaving processes. This adaptability is critical for maintaining sample integrity throughout various lab procedures. The labels are made by Advantech Manufacturing, a company known for its reliable lab supplies.
Performance & Functionality
The VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19 excels at its primary function: providing a reliable and legible means of identifying samples in extreme temperatures. The labels adhere strongly to various surfaces, including plastic and glass. They also remain legible even after repeated freeze-thaw cycles.
One of the strengths of these labels is their ease of use. The dot shape is convenient for applying to small tubes and vials. The adhesive backing is strong, yet the labels are still relatively easy to remove if necessary without leaving behind excessive residue. A minor weakness is the lack of pre-printed fields. However, this can easily be overcome with a permanent marker.
Overall, the VWR Vwr Label Cryo Dot Wht Cs1000 VWR-C19 meets and exceeds my expectations for a cryogenic label. They offer exceptional performance and reliability in demanding conditions.
