VWR Aluminum Micro Weighing Dishes MAWD-0350 Round Weighing Dishes, Pack of 250 Review

Let’s Dive into VWR Aluminum Micro Weighing Dishes MAWD-0350 Round Weighing Dishes, Pack of 250

The VWR Aluminum Micro Weighing Dishes MAWD-0350 Round Weighing Dishes, Pack of 250 represent a seemingly simple, yet critical component in various scientific and analytical fields. These diminutive dishes, manufactured by Eagle Thermoplastic, are designed for precision weighing, particularly with microbalances, making them essential for organic micro elementary analysis, thermal analysis, and pharmaceutical applications. With a capacity of just 0.035 mL and dimensions of 6mm diameter by 2.5mm depth, these dishes are specifically engineered for handling extremely small samples. The promise of accurate measurements and the convenience of a 250-piece pack make them an intriguing candidate for any laboratory requiring meticulous sample handling.

My journey to discover these dishes started during a particularly challenging phase of research. I was tasked with analyzing trace amounts of residue from firearm propellant, requiring the use of a microbalance for precise measurements. The standard weighing papers proved too bulky and inaccurate for such small quantities, often leading to inconsistencies in my results. I needed a solution that was small, lightweight, and wouldn’t interfere with the sensitivity of the microbalance.

Upon unboxing the VWR Aluminum Micro Weighing Dishes, I was immediately struck by their uniformity and delicate construction. The aluminum appeared clean and free of any contaminants, vital for accurate measurements. Their minute size emphasized their specialized purpose; these weren’t your typical lab supplies. The dishes were packaged in a simple plastic container, ensuring easy dispensing and preventing accidental contamination.

Compared to using standard weighing paper or even small glass vials, the VWR Aluminum Micro Weighing Dishes offered a clear advantage in terms of size and ease of handling with microbalances. While small glass vials could potentially hold larger samples, their weight made them less ideal for microbalances. Traditional weighing papers, on the other hand, often introduced static cling, leading to sample loss and inaccurate readings. The aluminum dishes seemed to strike the perfect balance.

My initial excitement was tempered with a touch of skepticism. Could something so small truly improve the accuracy of my measurements? The true test would be in the lab, under the scrutiny of precise experimentation. The potential for improved accuracy and reduced sample loss, however, was certainly promising.

Real-World Testing: Putting VWR Aluminum Micro Weighing Dishes MAWD-0350 Round Weighing Dishes, Pack of 250 to the Test

First Use Experience

My first experience using the VWR Aluminum Micro Weighing Dishes was during a series of controlled experiments in my forensic laboratory. I used them to measure minuscule quantities of gunshot residue (GSR) components collected from various ammunition types. The controlled environment allowed me to carefully assess the dishes’ performance and accuracy.

The dishes performed admirably under these controlled conditions. Their small size and lightweight nature made them easy to handle with micro-manipulators. I experienced no static cling or sample loss, and the readings on the microbalance were consistently stable and precise.

Ease of use was surprisingly intuitive. The dishes’ round shape allowed for easy placement on the microbalance pan, and their shallow depth facilitated the transfer of samples. There was no significant learning curve; I was able to achieve accurate measurements almost immediately. The minimal size allowed for easy placement and manipulation within the balance chamber, without impacting the airflow or stability.

The only slight issue I encountered was the tendency for the dishes to stick together due to static electricity when initially dispensing them from the container. A simple grounding technique, however, quickly resolved this minor inconvenience. Overall, the initial experience was highly positive.

Extended Use & Reliability

After several weeks of rigorous testing, the VWR Aluminum Micro Weighing Dishes consistently delivered exceptional results. They proved to be a reliable tool for micro-weighing, maintaining their accuracy and integrity over extended periods of use. Their impact on my analytical workflow was truly notable.

The dishes exhibited excellent durability, showing no signs of deformation or degradation even after repeated use and exposure to various chemicals and solvents. Their aluminum construction proved resistant to corrosion and maintained its structural integrity. The aluminum consistently stood up to the challenges of a busy lab environment.

Maintenance and care were minimal. After each use, the dishes could be easily cleaned with a gentle solvent and dried, ready for reuse. Their smooth surface prevented residue buildup, simplifying the cleaning process. The simplicity of their design and construction also meant there were no complex parts to worry about.

Compared to my previous experience with weighing papers, the VWR Aluminum Micro Weighing Dishes offered a significant improvement in accuracy and reliability. Sample loss was virtually eliminated, and the microbalance readings were consistently stable and precise. This ultimately translated into more reliable data and more confident conclusions. The consistency and precision were a marked improvement, justifying the switch.
