Walter Stern Large Rubber Bulbs 200-60 Review

Let’s Dive into Walter Stern Large Rubber Bulbs 200-60

The Walter Stern Large Rubber Bulbs 200-60 might not seem like the most glamorous piece of tactical gear, but sometimes the unsung heroes are the most essential. These aren’t your everyday squeeze toys; they are precision instruments designed for specific applications requiring chemical resistance and temperature stability. I first encountered these bulbs when trying to develop a field-expedient water purification system for long-range reconnaissance.

I needed a reliable and chemically inert way to precisely measure and dispense water purification chemicals. I was tired of improvising with flimsy droppers and syringes that often failed or reacted with the chemicals. When researching options, the Walter Stern Large Rubber Bulbs 200-60 kept popping up due to their robustness and compatibility with various chemicals.

Upon receiving the Walter Stern Large Rubber Bulbs 200-60, my initial thought was, “This is surprisingly well-made.” The rubber felt significantly more durable than standard lab equipment I’d used in the past, and the threaded ends suggested a secure connection point. The graduations were clear and precise, a critical feature for accurate measurements.

I considered cheaper, generic rubber bulbs, and even some plastic syringes, but the promised chemical resistance and the threaded connections of the Walter Stern Large Rubber Bulbs 200-60 ultimately swayed my decision. I also liked the idea of being able to use them as positive displacement valves in custom setups. My first impression was one of cautious optimism; they looked the part, but the real test would be in the field.

Real-World Testing: Putting Walter Stern Large Rubber Bulbs 200-60 to the Test

First Use Experience

I first tested the Walter Stern Large Rubber Bulbs 200-60 during a simulated survival exercise in a humid, subtropical environment. The primary purpose was to test its suitability for dispensing iodine tincture for water purification. I submerged the bulb in a stream to draw water, then carefully added the iodine.

The bulb performed admirably, even with wet hands and the slightly slippery rubber. The threaded connection to my improvised dispensing tube remained secure, and the chemical resistance of the bulb was evident as there was no degradation or discoloration after repeated exposure to the iodine solution. I didn’t need any time to get used to it, its usability was immediate.

The only minor issue was the lack of an air chamber, which required a bit more technique to draw precise amounts of liquid.

Extended Use & Reliability

After several months of sporadic use, including exposure to various temperatures and chemicals, the Walter Stern Large Rubber Bulbs 200-60 have held up remarkably well. There has been no noticeable degradation of the rubber, and the graduations remain clear and legible. Cleaning them is straightforward – a simple rinse with water usually suffices, although a mild solvent can be used for more stubborn residues.

Compared to the improvised methods I used before, the Walter Stern Large Rubber Bulbs 200-60 are a significant improvement in both reliability and precision. They have become an indispensable part of my field kit, consistently outperforming any makeshift solution I’ve tried. The robustness of the valve stem is notable.
