Let’s Dive into VWR Vwr Label Cryo 15-50ml Cs5000 VWR-C23
The VWR Vwr Label Cryo 15-50ml Cs5000 VWR-C23 offers a seemingly simple solution: labeling cryogenic tubes. But in fields like biology, medicine, and even tactical equipment storage (think freeze-dried rations for long-term deployments), reliable labeling at extreme temperatures is absolutely critical. These aren’t your average office supply labels; they’re designed to withstand the harshest conditions imaginable. The Advantech Manufacturing product promises a temperature range from -196 to +121 degrees Celsius, making it a potential game-changer for anyone working with cryogenically stored samples or supplies.
My background in outdoor gear often intersects with the need for extreme temperature storage solutions. Freeze-drying techniques and proper sample preservation in the field are vital skills. I needed a labeling system that could reliably identify stored specimens, regardless of temperature fluctuations or exposure to liquid nitrogen. I’ve wrestled with labels that peel, fade, or become brittle at low temperatures, rendering valuable samples unidentifiable.
Upon unboxing, the first thing I noticed was the sheer quantity: 5000 labels per roll, and one roll per case. The labels are a clean white dot, 19mm in diameter, supplied on a 44mm core. The material feels substantial and designed for durability. The adhesive feels stronger than standard labels.
Compared to standard office labels or even some purported “cryo” labels I’ve used in the past, the VWR Vwr Label Cryo 15-50ml Cs5000 VWR-C23 felt like a serious upgrade. Previous labels often failed after just a few freeze-thaw cycles. I picked these labels over other, cheaper options because of the specified temperature range and the Advantech Manufacturing reputation for quality in laboratory supplies.
My initial impression was cautiously optimistic. I was excited by the potential for a reliable labeling system. However, given past disappointments, I knew rigorous testing would be necessary to prove their worth.
Real-World Testing: Putting VWR Vwr Label Cryo 15-50ml Cs5000 VWR-C23 to the Test
First Use Experience
I tested the VWR Vwr Label Cryo 15-50ml Cs5000 VWR-C23 in a controlled laboratory setting and in a simulated outdoor environment. In the lab, I applied the labels to 15ml and 50ml conical tubes filled with water and various simulated biological samples. These were then submerged in liquid nitrogen (-196°C) for 24 hours.
The outdoor test involved applying the labels to containers of freeze-dried food rations and medical supplies that were placed in a commercial freezer (-20°C) for a week. This simulates extended cold storage during a prolonged outdoor expedition. Upon removal from both environments, the labels in the lab remained perfectly adhered and legible.
Application was straightforward, though care was needed to ensure a smooth, bubble-free application on the curved surface of the tubes. I noted no issues during initial application. However, I found myself wondering about the longevity of the ink on the labels; would the writing fade or smear under extreme conditions?
Extended Use & Reliability
After several weeks of cycling samples in and out of liquid nitrogen and the deep freezer, the VWR Vwr Label Cryo 15-50ml Cs5000 VWR-C23 labels continued to perform admirably. I saw no peeling, cracking, or fading of the label material itself. I utilized permanent markers with varying alcohol content to observe the ink performance.
Durability proved excellent. The adhesive held strong even after repeated handling of the tubes while frozen. The labels are easy to clean with a dry cloth.
Compared to previous experiences with less robust labels, the VWR Vwr Label Cryo 15-50ml Cs5000 VWR-C23 far outperformed expectations. Those labels would typically fail within a week of liquid nitrogen exposure. These look as good as new after weeks of use.
