Performance & Functionality
The Kimble/Kontes KIMAX Burets, Class A, Straight Bore PTFE Stopcock, Kimble Chase 17027F 50 excels at accurately dispensing liquids for titration and other volumetric analyses. Its primary strengths lie in its precision, smooth operation, and chemical resistance. The fine graduations and precise stopcock control make it easy to deliver the exact amount of titrant needed for accurate results.
A minor weakness could be the all-glass construction, making it susceptible to breakage if dropped or mishandled. Overall, the buret meets and exceeds expectations for a Class A volumetric instrument.
Design & Ergonomics
The buret is constructed from high-quality KIMAX borosilicate glass, known for its chemical resistance and durability. While glass is inherently fragile, the construction feels robust. The length (745mm) can be a bit unwieldy, requiring a secure stand for proper use.
There is a slight learning curve to mastering the stopcock control for dropwise dispensing, but the design is ultimately user-friendly. The white ceramic enamel scale is clear and easy to read.
Durability & Maintenance
With proper care, the Kimble/Kontes KIMAX Burets, Class A, Straight Bore PTFE Stopcock, Kimble Chase 17027F 50 should last for many years. The glass construction is chemically resistant to most common laboratory reagents. Maintenance involves rinsing with distilled water or a suitable cleaning solution after each use to prevent contamination.
The PTFE stopcock requires occasional lubrication (if needed) with a suitable Teflon-based lubricant. The buret is relatively easy to clean and maintain.
Accessories and Customization Options
The buret comes standard with a KIM-KAP dust cap to protect the top opening from contamination. There are no specific customization options for the buret itself. However, it is compatible with various standard buret stands and clamps available from different brands.
