Kimble/Kontes Buret No Stpk 25ML PK1 17021J 25 Review

Let’s Dive into Kimble/Kontes Buret No Stpk 25ML PK1 17021J 25

The Kimble/Kontes Buret No Stpk 25ML PK1 17021J 25 is a replacement borosilicate glass barrel designed for precise liquid dispensing. Manufactured by Kimble/Kontes, this 25mL buret barrel is a crucial tool for any lab setting requiring accurate titrations or controlled fluid delivery. Its 0.10mL graduations offer a fine level of precision, making it an essential component in quantitative chemical analysis.

My journey towards acquiring the Kimble/Kontes Buret No Stpk 25ML PK1 17021J 25 started with a need for accurate volumetric measurements in my small-scale brewing experiments. I needed a reliable and precise method for measuring hop additions and pH adjustments during the brewing process. Standard household measuring devices lacked the required accuracy.

Upon unboxing, the first thing I noticed was the quality of the glass. The borosilicate material felt robust, and the graduations were clearly marked and easy to read. Its simple design exuded a sense of precision and reliability that I found immediately reassuring.

I considered a few other options, including complete burets from other manufacturers and digital measuring devices. Ultimately, I chose the Kimble/Kontes replacement barrel because I already owned a compatible buret stand and the Kimble/Kontes name is synonymous with quality labware. It was also the most economical choice.

My initial impression was one of cautious optimism. While the barrel itself appeared to be well-made, I was eager to see how it would perform in actual use and whether it would truly improve the accuracy of my measurements. The price of $81.99 seemed a little high for just a replacement barrel, but I was betting on Kimble/Kontes’s reputation.

Real-World Testing: Putting Kimble/Kontes Buret No Stpk 25ML PK1 17021J 25 to the Test

First Use Experience

My first test of the Kimble/Kontes Buret No Stpk 25ML PK1 17021J 25 was during a pH titration of a batch of homemade wine. I needed to accurately measure and add potassium hydroxide solution to adjust the acidity. The buret was mounted on my existing stand, and I carefully filled it with the potassium hydroxide solution.

Under normal indoor lighting conditions, the graduation markings were clear and easily readable. The controlled dispensing of the solution allowed for precise adjustments to the pH levels. I found that I didn’t need any significant time to get used to the buret, given that I had previously used burets of similar designs.

After the first use, I noted that the glass was easy to clean, and there were no visible signs of chemical attack from the solutions used. I was initially concerned about potential leaks where the barrel connected to the stopcock, but the seal remained tight throughout the experiment. The precision it offered was substantially better than using graduated cylinders for the additions.

Extended Use & Reliability

After several weeks of use in various brewing and winemaking experiments, the Kimble/Kontes Buret No Stpk 25ML PK1 17021J 25 has proven to be a reliable and accurate tool. There are no signs of wear or tear on the glass. The graduations remain clear and easy to read.

Maintenance has been straightforward. After each use, I thoroughly rinse the barrel with distilled water and allow it to air dry. I occasionally use a mild detergent to remove any stubborn residue. Compared to using less precise measuring tools, the Kimble/Kontes buret has significantly improved the consistency and quality of my results.

This Kimble/Kontes buret barrel has definitely outperformed my initial expectations. Its accuracy and ease of use have made it an indispensable tool in my brewing setup. The improved precision in measuring liquids makes this worth the investment.

Breaking Down the Features of Kimble/Kontes Buret No Stpk 25ML PK1 17021J 25

Specifications

• Description: BURET NO STPK 25ML PK1. This clearly states that it is a buret barrel designed for use without a stopcock mechanism.
• Manufacturer: Kimble/Kontes. Kimble/Kontes is a well-respected name in laboratory glassware, known for its quality and precision.
• Capacity: 25mL. This volume is ideal for applications requiring relatively small and precise liquid dispensing.
• Graduations: 0.10mL. The fine graduations allow for highly accurate measurements, essential for precise titrations and controlled additions.
• Length: 336mm. This length provides a suitable column of liquid for accurate readings while remaining manageable on a standard buret stand.
• Material: Borosilicate glass. Borosilicate glass offers excellent chemical resistance and thermal stability, crucial for handling various solutions without degradation or contamination.

These specifications are critical for ensuring accurate and reliable performance. The borosilicate glass prevents chemical interactions, while the fine graduations enable precise measurements. The 25 mL capacity is suitable for most laboratory titrations.

Performance & Functionality

The Kimble/Kontes Buret No Stpk 25ML PK1 17021J 25 excels at providing precise liquid dispensing. It allows for controlled and repeatable measurements. The clarity of the glass and the distinct graduation markings make it easy to read the volume accurately.

Its main strength lies in its accuracy and reliability. Its weakness is that you need a separate stopcock assembly, as this is just the barrel. It exceeded my expectations in terms of precision, as my wine pH adjustments became much more predictable.

Design & Ergonomics

The buret’s simple design is focused on functionality. The borosilicate glass is robust, offering both chemical resistance and durability. The buret is lightweight and comfortable to handle when mounting or dismounting it from the stand.

The design is user-friendly. The clear markings require minimal learning.

Durability & Maintenance
