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 run was at a remote stream, assessing water quality after a simulated contamination event. Using the Kimble/Kontes KIMAX Reservoir Micro Burets, Class A, Straight Bore PTFE Stopcocks, Kimble Chase 17132F-10 in direct sunlight made reading the graduations a bit challenging. The stopcock, however, operated flawlessly, delivering consistent, drop-by-drop control even with gloved hands.
The buret performed well in moderate temperatures, but I noted concerns about its usability in freezing conditions due to potential cracking or expansion of the liquid. The need to constantly refill the reservoir in windy conditions proved frustrating, introducing potential contamination. After the first use, I realized the included stopper was not air-tight, allowing for some evaporation and potential changes in concentration of the titrant within the reservoir over time.
Extended Use & Reliability
After several weeks of laboratory and limited field use, the glass remained pristine, showing no signs of chemical etching or degradation. Transporting the Kimble/Kontes KIMAX Reservoir Micro Burets, Class A, Straight Bore PTFE Stopcocks, Kimble Chase 17132F-10 required significant padding and careful handling; one minor bump resulted in a chip near the top of the reservoir. Cleaning was relatively easy with standard laboratory detergents, but the narrow bore required patience and specialized brushes.
Compared to a similar automatic piston buret I’ve used in the past, the Kimble/Kontes KIMAX Reservoir Micro Burets, Class A, Straight Bore PTFE Stopcocks, Kimble Chase 17132F-10 is far more susceptible to environmental factors and user error but, when properly handled, provides comparable accuracy without relying on any power source. The glass is durable enough for lab use but far too fragile for tactical use in the field.
Breaking Down the Features of Kimble/Kontes KIMAX Reservoir Micro Burets, Class A, Straight Bore PTFE Stopcocks, Kimble Chase 17132F-10
Specifications
The Kimble/Kontes KIMAX Reservoir Micro Burets, Class A, Straight Bore PTFE Stopcocks, Kimble Chase 17132F-10 boasts a 10 mL capacity with 0.05 mL graduations. Its accuracy is rated at ±0.02 mL, adhering to Class A standards. The manufacturer, Kimble Chase, specifies a length of 620 mm and uses borosilicate glass (KIMAX) known for its chemical resistance and thermal stability.
- Key Feature: Class A Accuracy: This ensures reliable and repeatable results, crucial for quantitative analysis.
- PTFE Stopcock: Offers smooth, leak-free operation and excellent chemical resistance, minimizing contamination risks.
Performance & Functionality
The Kimble/Kontes KIMAX Reservoir Micro Burets, Class A, Straight Bore PTFE Stopcocks, Kimble Chase 17132F-10 delivers accurate titrations when used correctly in a stable environment. Its primary strength lies in its simplicity and lack of reliance on electronic components. The weaknesses include its fragility and susceptibility to user error in reading the meniscus and controlling the stopcock.
This buret meets expectations for laboratory use, providing accurate volumetric dispensing. For field applications, its fragility requires extreme caution and significantly limits its usability.
Design & Ergonomics
The buret features a traditional design with a permanently attached 70mL reservoir and a side fill tube for convenient refilling. The durable white ceramic scale provides clear readings under optimal lighting conditions. The borosilicate glass construction feels robust, but the tall, slender design makes it prone to tipping and breakage.
The PTFE stopcock offers smooth and precise control, making it relatively user-friendly. However, precise readings demand good eyesight and steady hands.
Durability & Maintenance
The borosilicate glass construction provides excellent chemical resistance and thermal stability, ensuring a long lifespan with proper care. The main concern is the inherent fragility of glass, making it susceptible to breakage from impacts or thermal shock. Routine cleaning is essential to prevent contamination and ensure accurate readings.
