Getting My Hands on the VWR Vials, Borosilicate Glass, with Phenolic Screw Cap VW60957A 11 Capsule Type
The VWR Vials, Borosilicate Glass, with Phenolic Screw Cap VW60957A 11 Capsule Type are designed for secure storage and handling of various substances, particularly in laboratory and research environments. Made by VWR, these 11-dram vials boast borosilicate glass construction for chemical resistance and come equipped with phenolic screw caps to ensure a tight seal. With my background primarily in outdoor gear, the world of laboratory equipment might seem distant. However, my tactical experience has taught me the crucial importance of proper storage and transport of sensitive materials, from first-aid solutions to fuel samples in the field, sparking my interest in testing the robustness and reliability of these vials beyond their intended lab environment.
My initial motivation to acquire these vials came from a specific need: safely transporting water samples from remote locations during my fly fishing expeditions. Standard plastic containers often leach chemicals or break under pressure, contaminating the samples. I’d been searching for a more robust and chemically inert alternative.
Upon unboxing the VWR Vials, Borosilicate Glass, with Phenolic Screw Cap VW60957A 11 Capsule Type, I immediately noted the sturdy feel of the borosilicate glass. The vials had a reassuring weight and the phenolic screw caps felt substantial and well-made, inspiring confidence. Compared to the flimsy plastic vials I’d previously used, these were a definite upgrade.
I considered a few other options before choosing the VWR vials. I looked at smaller serum vials made of similar glass. I also briefly considered stainless steel containers, but the glass offered better visibility and resistance to certain chemicals. I ultimately chose these for the larger 11-dram capacity and the promise of a tighter seal due to the phenolic screw cap design.
My first impression was one of pleasant surprise. I was impressed by the build quality and the attention to detail in the cap design. I was eager to test them in the field and see how they would perform under real-world conditions, well outside the controlled environment of a lab.
Real-World Testing: Putting VWR Vials, Borosilicate Glass, with Phenolic Screw Cap VW60957A 11 Capsule Type to the Test
First Use Experience
My first test of the VWR Vials, Borosilicate Glass, with Phenolic Screw Cap VW60957A 11 Capsule Type was on a multi-day backpacking and fly fishing trip in the Sierra Nevada mountains. I used the vials to collect water samples from various streams and lakes to send back for analysis. The vials were packed in a padded section of my backpack along with other delicate gear.
The vials performed well in varying conditions. The weather ranged from sunny and dry to a brief rain shower, and the temperature fluctuated significantly. The vials showed no signs of leakage, and the phenolic caps remained securely fastened.
The vials were relatively easy to use. The wide mouth made filling them simple, even in a rushing stream. I did find that labeling the vials before filling was crucial, as the smooth glass surface made writing on them when wet difficult.
The most surprising issue after the first use was the weight of the filled vials. Glass, naturally, is heavier than plastic. I had to adjust my packing strategy to compensate for the increased weight of multiple full vials.
Extended Use & Reliability
After several months of using the VWR Vials, Borosilicate Glass, with Phenolic Screw Cap VW60957A 11 Capsule Type on various outdoor excursions, they have proven to be quite durable. I’ve used them for everything from storing small quantities of fishing line lubricant to carrying emergency rations of spices. The vials held up well even when accidentally dropped on softer surfaces.
Despite some rough handling, there are no visible signs of significant wear and tear. The glass is remarkably scratch-resistant, and the phenolic caps continue to provide a tight seal. Cleaning the vials is straightforward; soap and water are sufficient for most applications.
Compared to my previous reliance on plastic containers, the VWR vials are a significant upgrade. They are more robust, chemically inert, and provide a much greater sense of security when transporting sensitive materials. While the weight is a factor, the benefits far outweigh this drawback.
