Let Me Walk You Through the VWR Aluminum Micro Weighing Dishes MAWD-1201 Oval Weighing Dishes, Pack of 250

For over a decade, I’ve been immersed in the world of outdoor and tactical gear, handling everything from high-end optics to the most basic survival tools. My work often intersected with scientific instruments in the field, leading me to appreciate the importance of even seemingly simple lab supplies. The VWR Aluminum Micro Weighing Dishes MAWD-1201 Oval Weighing Dishes, Pack of 250 might not seem like tactical gear in the traditional sense, but their utility in field testing, sample collection, and precise measurement makes them invaluable for certain applications. This review will explore their strengths and weaknesses from a practical, field-oriented perspective.

I needed a reliable, contaminant-free method for weighing small samples in a mobile lab setup during environmental surveys. I was tired of improvising with makeshift containers or relying on flimsy plastic options that introduced static and potential contamination. The promise of consistent weight and clean transfer made the VWR Aluminum Micro Weighing Dishes MAWD-1201 Oval Weighing Dishes, Pack of 250 an appealing solution.

The dishes arrived in a sturdy, resealable plastic container, ensuring they remained clean and undamaged during shipping. My initial impression was favorable; the aluminum felt solid, not flimsy, and the oval shape seemed more practical than round dishes for scooping and pouring. They appeared well-made and ready for precise work.

I considered similar products from Fisher Scientific and Cole-Parmer, both reputable brands, but the VWR offering seemed to strike a better balance between price and quantity for my specific needs. Ultimately, the oval shape and positive reviews regarding material purity swayed my decision. I was cautiously optimistic, hoping these dishes would streamline my workflow and minimize potential errors.

Real-World Testing: Putting VWR Aluminum Micro Weighing Dishes MAWD-1201 Oval Weighing Dishes, Pack of 250 to the Test

First Use Experience

My first field test involved analyzing soil samples for heavy metal content at a remote site known for industrial contamination. I used the VWR Aluminum Micro Weighing Dishes MAWD-1201 Oval Weighing Dishes, Pack of 250 to weigh the dried soil before digestion and analysis. Their performance was impressive in the dry, dusty environment.

The oval shape made it easy to scoop small quantities of soil directly from the sample bags, minimizing spillage. I found the dishes easy to handle, even with gloved hands, and they sat securely on my portable microbalance. I did not experience any static cling, a common problem with plastic alternatives.

Extended Use & Reliability

After several weeks of rigorous use, the VWR Aluminum Micro Weighing Dishes MAWD-1201 Oval Weighing Dishes, Pack of 250 have proven remarkably durable. Despite being made of thin aluminum, they resist bending and deformation well. I even accidentally stepped on one (while empty!) and it only suffered a slight crease, remaining usable.

Cleaning is simple; a quick rinse with distilled water and a wipe with a lint-free cloth is sufficient. I haven’t noticed any signs of corrosion or degradation, even after repeated exposure to various chemicals during sample processing. Compared to my previous reliance on disposable plastic weigh boats, these VWR dishes offer superior reliability and reduce the risk of contamination.
