Real-World Testing: Putting VWR VistaVision Cover Glasses, No. 11/2 1152240 Rectangular to the Test
First Use Experience
I tested the VWR VistaVision Cover Glasses in my mobile field lab during a biodiversity survey in a remote rainforest location. The high humidity and variable temperatures of the rainforest presented a challenging environment for microscopy. The cover glasses were used to prepare and protect samples of leaf litter, soil microorganisms, and waterborne parasites for microscopic examination.
Despite the demanding conditions, the cover glasses maintained their integrity and optical clarity. They were easy to handle and did not exhibit any signs of fogging or distortion, even in the humid environment. The consistent dimensions of the glasses allowed for precise focusing and imaging, regardless of the environmental conditions. Initial use revealed an increased level of image clarity and a noticeable decrease in background noise compared to my previous cover glasses.
Extended Use & Reliability
After several weeks of continuous use, the VWR VistaVision Cover Glasses have proven to be remarkably durable and reliable. I subjected them to repeated cleaning with various solvents and disinfectants without any signs of degradation or scratching. Their consistency has minimized the need to recalibrate the microscope between sample preparations.
Durability has been outstanding; even after weeks in the field, there are no signs of clouding or scratching, which was a common issue with previous brands. Cleaning is easy; a quick wipe with lens cleaner and a microfiber cloth is all it takes to maintain their pristine condition. They far outperform anything I’ve used before in terms of both optical clarity and durability, providing unparalleled consistency in my results.
