Let’s Dive into VWR Graduated Beakers, Low Form, PMP K1722-VWR
The VWR Graduated Beakers, Low Form, PMP K1722-VWR might seem like an odd choice for an outdoor gear specialist, but precision and accuracy extend far beyond ballistics and navigation. Even in the field, repeatable measurements are crucial for everything from water purification to first-aid mixing. VWR, a well-respected name in laboratory equipment, offers these beakers molded from polymethylpentene (PMP), known for its clarity and chemical resistance.
My need for these beakers stems from a desire for more controlled experimentation in my backcountry survival skills. I wanted a reliable, heat-resistant vessel for measuring liquids during water purification and other essential tasks. Previously, I was relying on imprecise markings on repurposed containers, leading to inconsistent results.
The beakers arrived well-packaged, each nestled in its own protective sleeve. My initial impression was positive: the PMP plastic is crystal-clear, allowing for easy viewing of the liquid level. The weight is surprisingly light, an important factor when considering pack weight for extended trips.
I considered several other options, including polypropylene beakers and graduated cylinders. I chose the VWR beakers for their wider temperature range and perceived durability compared to polypropylene. The low form design also seemed more stable for use on uneven surfaces in a field environment.
My first impression was one of cautious optimism. They seemed well-made and fit the bill for my needs, but the real test would be how they performed in rugged conditions.
Real-World Testing: Putting VWR Graduated Beakers, Low Form, PMP K1722-VWR to the Test
First Use Experience
My first opportunity to test the VWR Graduated Beakers, Low Form, PMP K1722-VWR came during a week-long solo trip to the Adirondack Mountains. I primarily used the beaker for measuring water volumes during the purification process, using both chemical treatments and boiling. The large spout made pouring water into my hydration reservoir much easier, reducing spillage.
The beaker performed admirably even in challenging conditions. I tested it in near-freezing temperatures and in light rain; the graduations remained clear and easy to read. I didn’t initially realize how much the PMP material would resist residue build-up; other materials I’ve used seem to hold onto dirt particles more easily.
The ease of use was impressive. The low form design made the beaker stable on uneven ground, which was a huge improvement over taller, narrower containers I’d used before. There were no immediate issues, though I did notice the plastic could potentially scratch if handled roughly around rocks.
Extended Use & Reliability
After several months of regular use, the VWR Graduated Beaker has proven surprisingly durable. I’ve used it on multiple camping trips, survival skills workshops, and even around the house for various tasks. Despite being tossed in a backpack with other gear, it has shown no signs of cracking or significant scratching.
The graduations remain clear and legible, even after repeated washing. Cleaning is a breeze; most dirt and grime simply washes away with soap and water. I did accidentally expose it to excessive heat once (near 200°C), resulting in slight warping.
Compared to my previous reliance on improvised measuring methods, the VWR Graduated Beakers, Low Form, PMP K1722-VWR is a game-changer. It offers far greater accuracy, durability, and ease of use. This drastically increases the reliability of measurements and experiments in the field.
