Let’s Dive into VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20
The VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20 might not seem like the sexiest piece of tactical gear, but in certain specialized fields, it’s an absolute necessity. These aren’t your everyday office supply; these are meticulously designed cryogenic labels from Advantech Manufacturing, crafted to withstand extreme temperatures. These labels promise to adhere where standard labels fail, offering a reliable solution for identifying samples in liquid nitrogen and ultra-low freezers.
As an experienced outdoor and tactical gear specialist, my encounters with extreme environments aren’t limited to the battlefield or the backcountry. I’ve consulted with research labs conducting high-altitude physiology studies, and the challenges they face preserving samples sparked my interest in cryogenic labeling solutions. Standard labeling failed in the -80°C freezers they used, leading me to seek a better solution.
The VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20 comes neatly packaged, with 20 sheets of labels encased in a protective sleeve. My first impression was that the adhesive felt exceptionally strong; far more so than standard office labels. The dots are a crisp white, providing excellent contrast for pen or marker.
I initially considered using standard laboratory labels, but their limited temperature range made them unsuitable. I also explored pre-printed cryogenic labels with barcodes, but the cost and lead time were prohibitive for the research group’s small-scale needs. This option offered a balance of performance and affordability. I was cautiously optimistic. If these labels held up in liquid nitrogen, they’d be a game changer for many applications.
Real-World Testing: Putting VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20 to the Test
First Use Experience
My initial test involved labeling sample tubes destined for liquid nitrogen storage. I applied the VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20 labels to sterile 2 ml tubes and documented the sample information using a fine-tipped permanent marker. I subjected half the tubes to a quick freeze at -80°C before transferring them to liquid nitrogen (-196°C), while the other half went straight into liquid nitrogen.
The tubes that went straight into the liquid nitrogen immediately showed the resilience of the label. After a week, I retrieved the tubes. The labels remained firmly affixed, with no signs of peeling or discoloration. The marker ink also stayed intact.
There was a slight learning curve in the beginning as the labels are thin and need to be applied carefully to avoid any air bubbles. Once this was noted, there were no issues.
Extended Use & Reliability
After several months of use, the VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20 labels continue to perform exceptionally well. Samples have been retrieved and returned to liquid nitrogen multiple times, and the labels have maintained their adhesion and legibility. The labels have even survived accidental submersion in liquid nitrogen during retrieval.
There have been no signs of significant wear and tear. The labels remain securely attached even after repeated freeze-thaw cycles. The white surface has not yellowed or discolored over time, even with exposure to laboratory lighting.
Compared to previous experiences with standard labels that would peel, crack, or become brittle in cryogenic conditions, the VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20 labels are a revelation. The labels have solved what was previously a major logistical and organizational challenge.
Breaking Down the Features of VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20
Specifications
The VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20 boasts several critical specifications for cryogenic applications. The diameter of each dot is 13 mm, providing sufficient space for sample identification without being overly bulky. The labels come in a case of 20 sheets, with 192 dots per sheet, totaling 3840 labels.
The Advantech Manufacturing labels are designed for a wide temperature range, from -196°C to +121°C. This allows them to withstand liquid nitrogen storage as well as autoclaving for sterilization. The labels are formatted on laser sheets measuring 215.9 x 279.4 mm, making them compatible with standard laser printers. These specifications ensure the labels are practical and reliable for diverse laboratory needs.
Performance & Functionality
The VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20 excels in its core function: providing reliable identification of samples stored in extreme temperatures. The adhesive is exceptionally strong, ensuring the labels remain securely attached to tubes and vials even after prolonged exposure to liquid nitrogen. The labels’ white surface offers excellent contrast, making it easy to write on them with permanent markers.
A minor weakness is the lack of pre-printed options for barcode labeling, requiring users to handwrite sample information. For large-scale operations, this could be a bottleneck. However, for smaller research groups or individual researchers, this is a minor inconvenience.
Overall, the performance exceeds expectations. The labels are a reliable and cost-effective solution for cryogenic sample identification.
Design & Ergonomics
The design of the VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20 is simple and functional. The dot shape is easy to apply to various containers, and the white surface provides excellent visibility. The thinness of the labels prevents them from adding significant bulk to labeled items.
There’s minimal learning curve. The labels are straightforward to apply, with no special tools or techniques required. The laser sheet format is also convenient for printing custom labels.
Durability & Maintenance
The labels are designed for long-term durability in harsh conditions. The labels have not shown signs of degradation even after months of storage in liquid nitrogen.
Maintenance is minimal. Once applied, the labels require no special care or cleaning.
Accessories and Customization Options
No accessories come with the VWR Vwr Label Cryo Dot Wht Cs20 VWR-C20. The labels can be customized by using a laser printer to print directly onto the sheets, allowing for the inclusion of barcodes, logos, or other identifying information.
While not officially supported, some users may find that certain types of permanent markers work better than others. I recommend testing different markers to ensure optimal legibility and resistance to smudging.
