As a seasoned gear specialist, my expertise might seem out of place reviewing lab equipment. However, my decade-plus experience in the field has taught me to appreciate well-designed, reliable tools regardless of their intended use. I needed a high-precision dispensing tool for analyzing soil samples, specifically for pH and nutrient content in remote field locations, beyond relying on standard field test kits.
Upon unboxing, the first thing I noticed was the quality of the glass. The KIMAX glassware is known for its clarity and resistance to thermal shock, a critical factor considering the potential for temperature fluctuations in field labs. The threaded closure appeared robust and well-machined, inspiring confidence that it would prevent leaks.
Compared to cheaper burets with rubber stoppers, the Kimble/Kontes design seemed significantly more reliable. I also considered a digital titrator but chose the KIMAX buret for its simplicity, lack of reliance on batteries, and ability to function reliably under a broad range of environmental conditions, akin to selecting a mechanical watch over a smartwatch for wilderness expeditions. My first impression was cautiously optimistic – it felt like a serious piece of kit.
Real-World Testing: Putting Kimble/Kontes KIMAX Buret with Threaded Closure Fit, Straight Bore PTFE Stopcock, Kimble Chase 17034H 99 Accessory to the Test
First Use Experience
My initial testing of the Kimble/Kontes KIMAX Buret with Threaded Closure Fit, Straight Bore PTFE Stopcock, Kimble Chase 17034H 99 Accessory took place in a makeshift field lab during a soil survey. The humid conditions of the forest presented an immediate challenge, but the glass remained clear, and the graduations were easily readable, even under dim lighting. Setting up the buret was straightforward.
The PTFE stopcock provided smooth and precise control over the liquid flow, allowing for drop-by-drop dispensing. After the first titration, I was impressed by the accuracy of the measurements; the threaded closure proved effective in preventing any noticeable leakage. The only minor inconvenience was the need to frequently wipe the tip to prevent droplet formation, a common issue with all burets.
Extended Use & Reliability
After several weeks of consistent use, the Kimble/Kontes KIMAX Buret with Threaded Closure Fit, Straight Bore PTFE Stopcock, Kimble Chase 17034H 99 Accessory has proven its reliability. Despite being transported in a rugged case, the glass remained undamaged, and the threaded closure continued to provide a secure seal. Minor scratches on the glass are visible from transport, but have not affected usability.
Cleaning the buret is straightforward, and the KIMAX glass resists staining from the soil solutions. Compared to my previous experiences with less expensive glassware, the Kimble/Kontes buret’s precision and durability are significantly better. It’s the difference between a dependable multi-tool and a flimsy keychain trinket – one is essential, the other a potential liability.
Breaking Down the Features of Kimble/Kontes KIMAX Buret with Threaded Closure Fit, Straight Bore PTFE Stopcock, Kimble Chase 17034H 99 Accessory
Specifications
- Capacity: Buret Tip – This specification seems incomplete, as it refers only to the tip style and not the overall capacity. Typically, these burets come in 25ml, 50ml, or 100ml volumes.
- Graduations: The product description does not specify graduation intervals, but standard burets usually have graduations of 0.1 mL or 0.05 mL. This is crucial for determining the precision of measurements.
- Length: This is not specified, but burets are typically between 50-75cm long depending on their volume. The length influences the readability of the graduations.
- Cap Size: This is not clearly defined and probably refers to the size of the dust cap. However, its practical importance is negligible.
- Kimble Chase No.: 17034H 99 – This unique identifier is helpful for reordering and ensures you get the correct product. This is particularly helpful if you are ordering replacement parts.
- Threaded Closure Fit: This secures the stopcock assembly, preventing accidental dislodging during use and reducing leaks. This is an important feature.
- Straight Bore PTFE Stopcock: The Polytetrafluoroethylene (PTFE) stopcock provides a chemically inert and smooth-turning valve for precise liquid control. PTFE is resistant to most chemicals.
Performance & Functionality
The Kimble/Kontes KIMAX Buret with Threaded Closure Fit, Straight Bore PTFE Stopcock, Kimble Chase 17034H 99 Accessory performs its core function exceptionally well: precise liquid dispensing. The PTFE stopcock allows for very fine control, and the glass clarity ensures accurate reading of the meniscus. It excels in titration experiments where accuracy is paramount.
However, without knowing the exact graduation intervals, it is difficult to definitively quantify the buret’s accuracy. An improved specification description with graduation values would allow for better performance assessment.
Design & Ergonomics
The KIMAX glass is robust, and the threaded closure provides a secure connection, offering peace of mind during use and transport. The design prioritizes functionality over aesthetics.
The buret is relatively easy to use. However, a slightly wider base would improve stability.
Durability & Maintenance
The KIMAX glass construction ensures longevity, and the PTFE stopcock is chemically resistant, reducing the likelihood of corrosion or degradation. Regular cleaning is essential to prevent contamination.
Replacement parts, such as stopcocks and tips, are readily available, extending the buret’s lifespan. This contributes to its long-term value.
Accessories and Customization Options
The listed Kimble Chase accessory includes a KIM-KAP dust cap, preventing contamination when not in use. While there are limited customization options for the buret itself, it is compatible with standard buret stands and clamps.
Additional accessories could include a fine-tipped dispensing nozzle for even greater precision or a protective sleeve for added durability in harsh environments. A protective case would be beneficial.
