Real-World Testing: Putting VWR VistaVision Cover Glasses, No. 1 112430 Rectangular to the Test
First Use Experience
I first tested the VWR VistaVision Cover Glasses in our lab’s standard brightfield microscopy setup, imaging stained tissue samples. The immediate difference in image quality compared to the previous cover glasses was striking. The image was noticeably sharper, with better contrast and less distortion, which made identifying cellular structures much easier.
These VWR VistaVision Cover Glasses maintained excellent image quality even when using immersion oil, which is essential for high-magnification objectives. I didn’t encounter any issues with the oil interacting negatively with the glass, nor were there any problems with focus stability.
Using the VWR VistaVision Cover Glasses was straightforward, requiring no special handling or adjustments to our existing protocols. The uniform thickness and consistent size made them easy to work with and eliminated the need for constant refocusing when switching between samples. After the first use, the consistency I was looking for was definitely there.
Extended Use & Reliability
After several weeks of consistent use, the VWR VistaVision Cover Glasses have proven to be highly reliable. They continue to provide excellent image quality, and I haven’t encountered any noticeable degradation in performance.
There have been no issues with scratching or clouding, even after repeated cleaning with standard laboratory solvents. The glasses have held up well, maintaining their clarity and flatness throughout the testing period.
Cleaning and maintaining these cover glasses is extremely simple, and the borosilicate glass cleans easily with ethanol or isopropanol and a lint-free wipe. They significantly outperform the previous generic cover glasses, and these are a worthy investment.
Breaking Down the Features of VWR VistaVision Cover Glasses, No. 1 112430 Rectangular
Specifications
