Let’s Dive into VWR Vwr Vial 40ml Am .2ml Hcl Cs72 QLAV89080047
The VWR Vwr Vial 40ml Am .2ml Hcl Cs72 QLAV89080047, manufactured by VWR, might not be the typical piece of outdoor or tactical gear I usually review. However, reliable sample collection and storage are crucial in many field applications, from environmental science to forensic investigations. This particular vial, with its amber glass and pre-dosed hydrochloric acid, suggests a specific use case requiring careful preservation of samples.
My work often involves evaluating the gear used by search and rescue teams, as well as environmental monitoring groups. The need for dependable sample containers arose when assessing a team’s protocol for collecting water samples after a simulated chemical spill. We needed to ensure the samples were collected and stored correctly.
Upon receiving the VWR Vwr Vial 40ml Am .2ml Hcl Cs72 QLAV89080047, my first impression was one of purposeful design. The amber glass spoke of UV protection, and the included chipboard divider hinted at careful packaging. Compared to generic vials, like the standard clear glass vials available from various lab suppliers and the plastic screw-top containers some field teams use, the VWR vial promised superior sample preservation.
I was excited to see if the pre-dosed HCL would simplify the collection process for the team. Initial thoughts centered around the vial’s robustness and whether its specific design would offer a tangible advantage in real-world scenarios.
Real-World Testing: Putting VWR Vwr Vial 40ml Am .2ml Hcl Cs72 QLAV89080047 to the Test
First Use Experience
I tested the VWR Vwr Vial 40ml Am .2ml Hcl Cs72 QLAV89080047 during a simulated environmental contamination scenario on a training site. The scenario required collecting water samples from a stream and a nearby pond suspected of contamination. We needed to mimic real-world conditions.
The vials performed well under the fairly benign conditions; however, proper use necessitated careful handling, especially when opening and closing the vials in windy conditions. The pre-dosed HCL made the preservation process quicker, eliminating the need for field acidification. No immediate issues arose, but careful attention to detail was necessary to avoid accidental spillage or cross-contamination.
Extended Use & Reliability
After several weeks of simulated deployments, the vials proved to be consistently reliable for preserving water samples. There was no visible degradation or leaching from the amber glass, even after exposure to varying temperatures and indirect sunlight. Cleaning the vials after use required thorough rinsing and proper disposal procedures to manage the residual HCL.
Compared to the standard, non-preserved sample containers the team previously used, the VWR Vwr Vial 40ml Am .2ml Hcl Cs72 QLAV89080047 significantly improved the accuracy and stability of the samples during transport and storage. The amber glass and HCL consistently outperformed standard vials.
Breaking Down the Features of VWR Vwr Vial 40ml Am .2ml Hcl Cs72 QLAV89080047
Specifications
Description: The VWR Vwr Vial 40ml Am .2ml Hcl Cs72 is a 40ml amber glass vial designed for sample collection and preservation. Its amber glass construction provides protection against UV light degradation, critical for light-sensitive analytes.
Volume: Each vial has a 40ml capacity, suitable for most standard water sample collection protocols. This capacity strikes a balance between sample volume requirements and ease of handling in the field.
Pre-Dosed HCL: The vials contain 0.2ml of hydrochloric acid (HCL), pre-dosed to acidify the sample and prevent microbial activity. This acidification helps stabilize certain analytes, ensuring accurate laboratory analysis.
Material: Constructed from amber glass, which minimizes light exposure and prevents photodegradation of samples. Glass is also inert, minimizing the risk of leaching and contamination.
Closure: Features a 24mm Teflon-lined screw cap, ensuring an airtight seal and preventing leakage during transport. The Teflon lining prevents the cap from reacting with the sample.
Packaging: Ships with a chipboard divider, protecting individual vials during shipping and handling. This packaging is essential to maintain the integrity of the vials during transport.
Catalog Number: 71001-668 helps uniquely identify the vial for ordering and tracking purposes. This unique identifier is helpful for inventory control and restocking.
These specifications are important because they collectively contribute to the vial’s effectiveness in preserving sample integrity. The amber glass, pre-dosed HCL, and Teflon-lined cap work together to prevent sample degradation, ensuring reliable and accurate analytical results.
Performance & Functionality
The VWR Vwr Vial 40ml Am .2ml Hcl Cs72 performed its primary job of sample preservation admirably. The pre-dosed HCL greatly simplified the field collection process, eliminating the need for manual acidification and reducing the risk of human error. However, the screw-top cap needed to be carefully tightened to ensure a proper seal.
The vial’s strengths lie in its ease of use and the consistency of sample preservation. A potential weakness is the glass construction, which is more susceptible to breakage than plastic alternatives, requiring more careful handling during transport. The product met expectations, providing a reliable solution for water sample collection and preservation.
Design & Ergonomics
The vial’s amber glass is both functional and aesthetically pleasing. The 40ml size is manageable, even with gloved hands, and the screw-top cap is easy to operate.
The design is user-friendly, requiring minimal training to use effectively; however, the glass material adds weight compared to plastic vials, which may be a consideration for large sample sets.
Durability & Maintenance
The glass construction is inherently durable but prone to breakage upon impact. The screw cap also requires careful handling to avoid stripping the threads.
Maintaining the vials involves thorough cleaning with appropriate solvents after use and ensuring proper disposal of the HCL residue, following local regulations.
Accessories and Customization Options
The VWR Vwr Vial 40ml Am .2ml Hcl Cs72 doesn’t have traditional “accessories,” but its compatibility with standard laboratory equipment is noteworthy. It can be used with standard sample racks and storage containers. Labels for marking sample information can easily be affixed to the vials, and various sizes of Teflon tape can enhance the cap’s seal.
