First Use Experience
My first opportunity to field test the Kimble/Kontes KIMAX Heavy-Duty Centrifuge Tube, Round-Bottom, with Screw Cap, Kimble Chase 45212 50 came during a recent survey of water quality in a remote section of the Pacific Northwest. I utilized it for separating sediment from water samples collected from various streams and rivers. The tube was used in conjunction with a portable, hand-cranked centrifuge.
The tube performed admirably, even in the cold, damp conditions of the region. The screw cap remained securely sealed, preventing any leakage during transport, a common issue I’ve experienced with other brands. No additional time was needed to get used to it, its intended usage is pretty self-explanatory.
There were no immediate issues. The tube withstood the centrifugal forces generated by the hand-cranked device, and the round bottom facilitated easy sediment collection.
Extended Use & Reliability
After several weeks of intensive use, the Kimble/Kontes tube has proven to be remarkably durable. It has survived multiple centrifuging cycles, transport in rugged backpacks, and temperature fluctuations without showing any signs of cracking or degradation.
Despite repeated use and cleaning, the tube remains crystal clear, with no noticeable wear or discoloration. The markings are still sharp and legible.
Cleaning has been a breeze. A simple rinse with soap and water is usually sufficient to remove any residue. Its autoclavable nature is especially useful for sterilization between sample types.
Compared to previous experiences with cheaper centrifuge tubes, the Kimble/Kontes tube significantly outperforms them in terms of durability, reliability, and ease of use. The investment in a higher-quality product has already paid off in time saved and reduced risk of sample contamination.
