After several months of continuous use, the Kimble/Kontes bottles have proven to be incredibly reliable. They’ve survived multiple expeditions and countless cycles of filling, emptying, and sterilization. The borosilicate glass shows no signs of degradation, and the graduations remain clear and legible.
The only wear and tear observed is minor scuffing on the exterior of the glass, which is purely cosmetic and does not affect functionality. The black phenolic caps still provide a secure seal, although the white rubber liners require occasional inspection to ensure they remain pliable and free of cracks.
Maintaining the Kimble/Kontes bottles is simple. They are easily cleaned with soap and water, and their autoclavable design allows for thorough sterilization between uses. Compared to the flimsy plastic containers I used previously, these bottles offer a significant improvement in both durability and ease of maintenance.
