Let’s Dive into VWR Vwr Custody Seal Pk100 QHLA15900314
The VWR Vwr Custody Seal Pk100 QHLA15900314, manufactured by VWR, is a seemingly simple product with a crucial role. These seals, sold in packs of 100, are designed to ensure the integrity of containers and samples. They provide visual evidence of tampering, a necessity in various fields, especially in laboratory settings and controlled environments.
I first encountered the need for custody seals during a sensitive environmental testing project. We were collecting soil and water samples from a contaminated site, and maintaining the chain of custody was paramount to the integrity of our findings. Any question of tampering could invalidate the entire process, impacting the legal and environmental ramifications of the project.
The VWR Vwr Custody Seal Pk100 QHLA15900314 arrived in a simple, unassuming package. My initial thought was that they looked like glorified stickers, but upon closer inspection, I realized they were more sophisticated than that. The adhesive seemed strong, and the material itself had a reassuring quality, promising durability and resistance to tearing.
I considered using generic tamper-evident labels from an office supply store. However, those lacked the specific features needed for documented chain of custody, such as sequential numbering and a design that clearly indicates tampering. Ultimately, the VWR seals provided the specialized security I needed for this project.
My first impression was cautiously optimistic. While they appeared functional and well-made, the true test would come in their practical application and ability to withstand real-world conditions. I was eager to see if they lived up to their promise of maintaining the integrity of our samples.
Real-World Testing: Putting VWR Vwr Custody Seal Pk100 QHLA15900314 to the Test
First Use Experience
My first deployment of the VWR Vwr Custody Seal Pk100 QHLA15900314 was during the aforementioned environmental sampling project. We applied the seals to sample containers in the field, ensuring that each container was sealed immediately after collection. The environment was harsh – dusty, humid, and subject to temperature fluctuations.
The seals adhered well to both glass and plastic containers, even with some surface moisture. The sequential numbering was a crucial feature, allowing us to easily track each sample’s journey through the chain of custody. The application process was straightforward; simply peel, stick, and record the seal number.
Initially, I worried about the seals peeling off in the humid conditions, but they held firm. There were no immediate issues or surprises; the seals performed exactly as intended, providing a visual indication that the containers had not been opened since sealing. This added a layer of confidence in the integrity of our sample collection protocol.
Extended Use & Reliability
After several weeks of rigorous use across multiple field projects, the VWR Vwr Custody Seal Pk100 QHLA15900314 proved their worth. They consistently provided reliable tamper evidence, even under challenging environmental conditions. I transported samples in various vehicles, often exposed to vibrations and temperature extremes.
I noticed minimal signs of wear and tear on the seals, even after prolonged exposure to sunlight and moisture. The adhesive remained strong, and the seals retained their integrity, showing no peeling or cracking. Cleaning was unnecessary, as the seals are disposable.
Compared to previous experiences with inferior tamper-evident labels, the VWR seals were a significant improvement. Cheaper alternatives often failed to adhere properly, or their tamper-evident features were easily circumvented. The VWR Vwr Custody Seal Pk100 QHLA15900314 consistently outperformed these alternatives, giving me confidence in the security of my samples.
