The Truth About Using the Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13
The Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13 is a specialized piece of laboratory equipment designed for demanding centrifugation applications. This tube, manufactured by Kimble/Kontes, boasts a heavy-duty PTFE construction and a unique hourglass shape, promising superior heat transfer and chemical resistance. Its hefty price tag of $235.99 per pair begs the question: is this specialized tube worth the investment?
My journey to this product began with a persistent problem in our research lab. We were experiencing inconsistent results when centrifuging chemically aggressive samples, with our standard tubes often failing or degrading, thus risking sample loss. This led me to seek a more robust and chemically inert solution.
Upon unboxing the Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13, my initial impression was one of substantiality. The tubes felt incredibly solid and well-made, exhibiting the thick walls and robust construction promised in the description. The frosted finish and brown dye were initially confusing, however, they appear to serve a practical purpose, ensuring long-term stability and even heat distribution.
Compared to standard polypropylene centrifuge tubes and even glass alternatives, the Kimble/Kontes tube felt significantly more durable. Other options couldn’t handle the harsh solvents we used; hence, the Kimble/Kontes‘ heavy-duty PTFE seemed the best fit. I was cautiously optimistic, hoping that this tube would finally solve our centrifuge-related woes.

The performance in chemically aggressive conditions was immediately noticeable. The tubes showed absolutely no signs of degradation or leakage, a stark contrast to our previous experiences with less resistant materials. Use was straightforward as no special handling or preparation was necessary.
There were no issues at all during the first run, which was a welcome change. Previously, we had encountered tube failures even on the initial run with harsh chemicals, so the Kimble/Kontes tube was a pleasant surprise.
Extended Use & Reliability
After several weeks of consistent use, the Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13 has held up admirably. The tubes have been subjected to numerous centrifugation cycles involving various solvents, acids, and bases. There have been zero failures or signs of chemical attack on the PTFE material.
Durability is exceptional; after extended use, there are no visible cracks or warpage. The frosted finish has remained intact, and the dye has not leached out, confirming its long-term stability.
Maintenance is straightforward; the PTFE material is easy to clean and resistant to staining. A simple wash with mild detergent and water is sufficient to remove any residue. Compared to the fragile glass tubes we used previously, the Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13 is a clear winner in terms of durability and ease of maintenance.
Breaking Down the Features of Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13
Specifications
The Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13 features a unique hourglass design. This shape purportedly enhances heat transfer during centrifugation. It’s constructed from heavy-walled PTFE (Polytetrafluoroethylene). This offers exceptional chemical resistance.
The tube also features a frosted outer wall and a brown dye within the tube’s structure. The frosted finish aids in heat distribution and the brown dye serves to ensure long-term stability. The Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13 is specifically designed for high-speed centrifugation of aggressive chemicals.
These specifications are crucial because they directly influence the tube’s performance and reliability. The PTFE construction guarantees chemical inertness, while the hourglass shape and frosted finish optimize heat transfer. The heavy wall provides necessary strength for high-speed centrifugation.
Performance & Functionality
The Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13 excels in its primary function: containing and withstanding high-speed centrifugation of chemically aggressive samples. Its chemical resistance is exceptional, as it shows no signs of degradation when exposed to harsh solvents and acids. This ensures sample integrity and accurate experimental results.
The strength of the tube is evident when the centrifuge reaches maximum speed. This is because there is no deformation or collapse, as the sample remains secure throughout the process. The only weakness is the relatively high price point compared to standard centrifuge tubes. However, this is offset by its longevity and resistance to failure.
The tube certainly exceeds expectations in its ability to handle challenging samples without any compromise in performance. In our lab, it has dramatically reduced the risk of sample loss and improved the overall reliability of our centrifugation protocols.
Design & Ergonomics
The build quality is superb. The PTFE material is dense and uniform, and the thick walls inspire confidence. The Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13 weighs more than standard tubes, but that’s indicative of the robust construction.
The tube is user-friendly with its wide mouth and simple design. While there’s no complex setup involved, familiarity with proper centrifugation techniques is essential. There is no learning curve, and it integrates seamlessly into existing workflows.
Durability & Maintenance
Given the heavy-duty PTFE construction, the Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13 should last for a considerable time. This is provided that the correct usage and cleaning protocols are followed. Based on our experience so far, we expect these tubes to outlast standard centrifuge tubes by a significant margin.
Maintenance is simple, requiring only routine cleaning with mild detergents. PTFE is chemically inert, so there are no special cleaning agents required. The smooth surface also prevents sample adherence, making cleaning easier.
Accessories and Customization Options
The product description mentions a holder supplied with an adjustable stand and a molecular level for isolating reagents. This appears to be a separate accessory kit, not included as standard. The base tube itself does not offer customization options but it can be used in standard centrifuges with appropriate rotors.
Compatibility with accessories from other brands largely depends on the centrifuge rotor dimensions. As long as the rotor is designed to accommodate tubes of similar size and shape, the Kimble/Kontes Tube Cntrfg Hvy Ptfe S 13M CS6 45174 13 should be compatible.
