Real-World Testing: Putting Kimble/Kontes KIMAX Filtering Flasks with Detachable Plastic Sidearm, Capacity Scale, Kimble Chase 27065 250 to the Test
First Use Experience
The first test for the Kimble/Kontes KIMAX Filtering Flask was during a week-long water sampling expedition in the Cascade Mountains. The flask was used to filter stream water samples using a portable vacuum pump and standard filter paper. It performed admirably, with the graduation scale allowing for precise volume measurements of the filtered water collected.
The conditions were far from ideal: rain, mud, and fluctuating temperatures were constant challenges. The Kimble/Kontes KIMAX Filtering Flask, however, held up surprisingly well. The detachable sidearm proved to be a valuable feature, allowing me to pack the flask securely in my gear without worrying about breaking the glass connection.
Using the Kimble/Kontes KIMAX Filtering Flask was straightforward; the graduation scale was easy to read even in low light, and the flask was stable on uneven surfaces. The plastic sidearm also made it easy to connect the tubing from the vacuum pump, providing a secure and leak-free connection. The only minor issue was getting used to the finger grips on the sidearm, as they initially felt a bit stiff.
Extended Use & Reliability
After several months of continuous use, the Kimble/Kontes KIMAX Filtering Flask has proven to be a reliable and durable piece of equipment. There are no signs of cracking or etching on the glass, and the graduation scale remains clear and legible. The plastic sidearm is still securely attached and shows no signs of degradation, despite repeated autoclaving for sterilization.
The flask has endured several drops (thankfully, not from great heights) without sustaining any damage, a testament to the quality of the borosilicate glass. Cleaning is simple: a quick rinse with distilled water followed by autoclaving ensures complete sterilization. This is a major improvement over my previous flasks, which required more delicate handling and specialized cleaning solutions.
Compared to my older, generic flasks, the Kimble/Kontes KIMAX Filtering Flask is a clear winner in terms of durability, accuracy, and ease of use. It has significantly streamlined my water sampling process and given me greater confidence in the reliability of my data. The initial investment of $179.99 feels justified given the long-term benefits.
