Let’s Dive into Walter Stern Shallow Form Watch Glasses 110-105, Pack of 12
For over a decade, my work has involved testing gear in some of the harshest environments imaginable. From evaluating load-bearing vests under the scorching desert sun to analyzing the performance of freeze-dried meals during arctic expeditions, I’ve seen it all. That’s why, when I was asked to review the Walter Stern Shallow Form Watch Glasses 110-105, Pack of 12, I approached it with the same level of scrutiny. These aren’t your typical tactical tools, but in a well-equipped field lab or for anyone meticulous about their gear preservation, they can be surprisingly valuable.
My latest project demanded meticulous data collection in the field, and that meant bringing our mobile lab setup with us. Protecting samples from contamination and ensuring accurate measurements were paramount. We needed something reliable, reusable, and easy to clean. I looked at various options, ranging from disposable petri dishes to more elaborate containment systems. The Walter Stern Shallow Form Watch Glasses 110-105, Pack of 12 seemed like a practical compromise, offering a good balance between protection and ease of use.
Upon unboxing, I was immediately struck by the simplicity of the design. The Walter Stern watch glasses are exactly what the description suggests: shallow, concave, clear glass covers. The glass felt substantial, not flimsy, and the fire-polished edges gave them a surprisingly refined look. The pack of 12 was also appreciated, providing ample replacements or allowing for multiple simultaneous experiments.
I considered purchasing smaller, disposable plastic covers, but they felt wasteful and less reliable in terms of maintaining a seal. Higher-end, gasketed containers were overkill for our application. The Walter Stern Shallow Form Watch Glasses 110-105, Pack of 12 struck the right chord, offering a practical and economical solution.
My first impression was one of cautious optimism. I wasn’t expecting revolutionary performance, but I appreciated the solid build quality and the practicality of the design. The price point was also a pleasant surprise. It was time to put them to the test.
Real-World Testing: Putting Walter Stern Shallow Form Watch Glasses 110-105, Pack of 12 to the Test
First Use Experience
My initial field test took place in a rather unforgiving environment: a remote stretch of the Mojave Desert. We were analyzing soil samples, and the ever-present dust and fluctuating temperatures posed a significant challenge. I used the Walter Stern Shallow Form Watch Glasses to cover beakers containing our samples, hoping to minimize contamination. They were also used to aid evaporation of liquids in certain samples.
The glasses performed admirably. They provided a decent barrier against the pervasive dust, and their shallow form allowed for easy viewing of the samples inside. In the harsh sunlight, the clear glass offered excellent visibility. We worked through the heat of the day, the glass heated up along with the equipment.
There were no major issues, but I did notice that the glasses were somewhat prone to slipping on the smooth surface of the beakers, especially when tilted. Also a high-wind environment isn’t great for uncovered beakers. This wasn’t a deal-breaker, but it required a bit of extra caution.
Extended Use & Reliability
After several weeks of consistent use in various field locations (from arid deserts to humid coastal environments), the Walter Stern Shallow Form Watch Glasses have proven to be surprisingly durable. There are no visible cracks or chips, and the glass remains clear even after repeated cleaning. I’ve even accidentally dropped one on a hard surface without any damage.
Cleaning is a breeze. A simple rinse with soap and water is usually sufficient to remove any residue. For more stubborn stains, a quick wipe with isopropyl alcohol does the trick. Their inert composition also prevents unwanted chemical reactions with the samples.
Compared to previous methods of sample protection (plastic wrap or makeshift covers), the Walter Stern Shallow Form Watch Glasses are a significant upgrade. They offer superior protection, are more durable, and are far more convenient to use. This is a great upgrade to my kit.
Breaking Down the Features of Walter Stern Shallow Form Watch Glasses 110-105, Pack of 12

- Quantity: Pack of 12. Ensures an adequate supply for multiple uses or replacements.
- Category: Beakers, Test Tubes, Flasks, & Accessories. Meant to be used in a laboratory setting.
These specifications are important because they directly impact the usability and reliability of the product. The diameter is suitable for most common laboratory glassware, the soda-lime glass provides adequate protection against chemical reactions, and the fire-polished edges enhance safety and durability.
Performance & Functionality
The Walter Stern Shallow Form Watch Glasses 110-105, Pack of 12 perform their intended job exceptionally well. They effectively cover beakers and containers, protecting samples from dust, contaminants, and evaporation. The shallow concave design ensures that any condensation returns to the sample, preventing loss of valuable material.
The main strength lies in their simplicity and reliability. There are no moving parts to fail, and the glass is chemically inert, minimizing the risk of contamination. The only area for potential improvement would be to incorporate a slightly textured surface or a small lip to prevent slipping.
Overall, the Walter Stern Shallow Form Watch Glasses meet and exceed my expectations. They are a simple yet effective solution for protecting samples and ensuring accurate measurements.
