Let’s Dive into Kimble/Kontes KIMAX Brand Burets, Class B, Straight Bore Stopcock 17026F 10 Burets With Ptfe Stopcock, Case
The Kimble/Kontes KIMAX Brand Burets, Class B, Straight Bore Stopcock 17026F 10 Burets With Ptfe Stopcock, Case represent a cornerstone in any analytical laboratory. These aren’t just glass tubes; they are precision instruments designed for accurate dispensing of liquids, particularly in titration experiments. The Kimble/Kontes name itself carries weight, known for its commitment to quality and reliability in laboratory glassware. A set of ten Class B burets with PTFE stopcocks packed in a single case offers a cost-effective and convenient solution for labs needing multiple burets for various experiments.
My background in outdoor and tactical gear might seem unrelated. However, I’ve found that precision, durability, and reliability are crucial in any field, whether you’re calibrating chemical solutions or sighting in a rifle. I was searching for a reliable set of burets for setting up a portable water testing kit for field use, and the Kimble/Kontes KIMAX Brand Burets seemed like a good fit.
Unboxing the case revealed a neatly arranged set of burets, each individually wrapped for protection. The glass felt solid, and the PTFE stopcocks turned smoothly, suggesting a high level of craftsmanship. Compared to cheaper, no-name brands I’ve used in the past, the difference in quality was immediately noticeable.
Initially, I was excited about the potential for accurate and reliable field testing. There was a slight reservation about the fragility of glassware in outdoor environments, but the protective case offered some reassurance. This was definitely a step up from the plastic graduated cylinders I had been using for rough estimations.
Real-World Testing: Putting Kimble/Kontes KIMAX Brand Burets, Class B, Straight Bore Stopcock 17026F 10 Burets With Ptfe Stopcock, Case to the Test
First Use Experience
My initial testing took place in a controlled lab environment to establish a baseline for accuracy. I compared the burets against certified reference materials and documented any deviations. The burets performed admirably, delivering consistent and precise volumes with minimal effort.
Under slightly less controlled conditions (my garage), I tested the burets with common household solutions. While not as rigorous as a lab setting, this simulated the conditions I might encounter in the field. The PTFE stopcocks proved resistant to chemical attack, ensuring smooth operation even with aggressive solvents.
The burets were surprisingly easy to use, even with the slight learning curve associated with fine-tuning the stopcock. The graduation markings were clear and easy to read, minimizing parallax errors. My only initial concern was the stability of the burets when freestanding, which required a dedicated stand or clamp.
Extended Use & Reliability
After several weeks of repeated use, the Kimble/Kontes KIMAX Brand Burets showed no signs of degradation. The graduation markings remained sharp, and the stopcocks maintained their smooth operation. Cleaning was straightforward, thanks to the inert nature of borosilicate glass and PTFE.
The burets proved to be more durable than I initially anticipated, withstanding accidental bumps and minor impacts without shattering. However, I still treated them with utmost care, recognizing their inherent fragility compared to plastic alternatives. Compared to lower-quality burets I’ve used in teaching labs, these Kimble/Kontes burets have consistently outperformed them in terms of accuracy and reliability.
Breaking Down the Features of Kimble/Kontes KIMAX Brand Burets, Class B, Straight Bore Stopcock 17026F 10 Burets With Ptfe Stopcock, Case
Specifications
Capacity: 10 mL. This is ideal for small volume titrations, providing better resolution and accuracy in determining endpoint.
Graduations: 0.05 mL. The fine graduations enable precise readings, allowing for accurate dispensing of small volumes of titrant.
Tolerance: ±0.04 mL. This defines the acceptable error range for each buret, ensuring the user has confidence in the accuracy of their measurements. Class B tolerance is sufficient for many applications.
Length: 518 mm. The length is optimized for easy handling and clear visibility of the graduation markings.
Cap Size: 13 mm. The cap size refers to the dust cap that protects the top of the buret from contamination.
Stopcock: Straight Bore PTFE. PTFE (Teflon) stopcocks are chemically inert and provide smooth, leak-free operation. The straight bore design allows for easy cleaning and minimal dead volume.
Material: KIMAX Borosilicate Glass. KIMAX glass is known for its chemical resistance and thermal stability, making it ideal for use with a wide range of solutions.
Quantity: 10 Burets per Case. Buying in bulk offers cost savings and ensures that a lab has an ample supply of reliable burets.
Class: B. Class B glassware meets standard accuracy requirements for routine laboratory analyses.
Performance & Functionality
The Kimble/Kontes KIMAX Brand Burets excel in delivering accurate and repeatable results. The fine graduations and smooth stopcock action allow for precise dispensing, even with viscous solutions. The clarity of the KIMAX glass minimizes parallax errors, further enhancing accuracy.
One potential weakness lies in the inherent fragility of glassware, making them susceptible to breakage if mishandled. The burets fully meet expectations for Class B glassware, providing a reliable and accurate tool for volumetric analysis.
Design & Ergonomics
The burets are designed for ease of use, with clearly marked graduations and a smooth-turning stopcock. The straight bore stopcock allows for easy cleaning and prevents clogging. The case provides secure storage and transport, minimizing the risk of damage.
The build quality is excellent, with uniform glass thickness and a well-finished stopcock. While not designed for single-handed operation, the burets are comfortable to use with proper support.
Durability & Maintenance
With proper care, these burets should last for many years. The borosilicate glass is resistant to chemical attack and thermal shock. Cleaning is simple with soap and water or a suitable cleaning solution.
The PTFE stopcocks may require occasional lubrication to maintain smooth operation. Replacements are readily available if needed.
Accessories and Customization Options
The case itself serves as a primary accessory, providing protection and organization. Buret stands or clamps are essential for hands-free operation. While these burets don’t offer many customization options, their inherent design makes them compatible with standard titration setups.
