Full Disclosure: Kimble/Kontes KIMAX Reservoir Micro Burets, Class A, Straight Bore PTFE Stopcocks, Kimble Chase 17132F-10

The Kimble/Kontes KIMAX Reservoir Micro Burets, Class A, Straight Bore PTFE Stopcocks, Kimble Chase 17132F-10 represents a critical piece of equipment for precise liquid dispensing in laboratory settings. It boasts a 10 mL capacity with 0.05 mL graduations and a Class A certification, ensuring accuracy and reliability. The integrated 70mL reservoir and PTFE stopcock design promise ease of use and minimal contamination.

My work in specialized field research frequently demands extremely accurate small-volume dispensing of reagents in sometimes less-than-ideal field conditions. The inconsistent lighting, vibrations, and temperature fluctuations of field labs often undermine the precision of typical burets and pipettes. I needed a micro buret that could handle these challenges and maintain Class A accuracy while also being robust enough for the rigors of transport.

The Kimble/Kontes buret arrived well-packaged, highlighting Kimble Chase’s commitment to protecting delicate labware. The glass was pristine, and the PTFE stopcock moved smoothly, suggesting high build quality. The attached reservoir felt securely fastened.

Compared to other micro burets I’ve used, like those from BrandTech Scientific or Hirschmann Laborgeräte, the Kimble/Kontes KIMAX offered a unique combination of reservoir capacity and Class A certification. The Hirschmann burets were often more expensive, and some BrandTech models lacked the same level of robustness I needed for field applications. Initially, I was excited by the potential for improved accuracy and efficiency in my research.

Real-World Testing: Putting Kimble/Kontes KIMAX Reservoir Micro Burets, Class A, Straight Bore PTFE Stopcocks, Kimble Chase 17132F-10 to the Test

First Use Experience

My first test involved titrating soil samples in a makeshift field lab during an environmental impact assessment. The KIMAX buret performed admirably despite the uneven lighting and minor vibrations from nearby equipment. The straight bore PTFE stopcock allowed for fine control of the dispensing rate, crucial for accurate endpoint determination.

While the 70mL reservoir was sufficient for the day’s work, the side fill tube required some getting used to, particularly in the confined workspace. I spilled a small amount of titrant initially but quickly adapted to the filling technique. The buret’s stability, thanks to its broad base, was also a definite plus.

Extended Use & Reliability

After several weeks of use across different field sites, the Kimble/Kontes KIMAX buret has proven remarkably durable. There have been no chips, cracks, or signs of degradation despite frequent transport in a padded equipment case. The PTFE stopcock continues to operate smoothly without any leaks, maintaining its precision.

Cleaning is relatively straightforward, requiring only gentle washing with lab detergent and thorough rinsing with distilled water. Compared to my previous experiences with less robust burets, the KIMAX model has significantly reduced downtime and improved the reliability of my field titrations. It consistently outperforms cheaper plastic alternatives that often degrade quickly.
