Let’s Dive into Kimble/Kontes KIMAX Separatory Funnels, Squibb, Pear-Shaped, Kimble Chase 29048 1000 With ST Ground Glass Stopper And ST Ground Glass Stopcock
The Kimble/Kontes KIMAX Separatory Funnels, Squibb, Pear-Shaped, Kimble Chase 29048 1000 With ST Ground Glass Stopper And ST Ground Glass Stopcock is more than just laboratory glassware; it’s a tool crucial for precise liquid-liquid extraction. Kimble Chase, a renowned name in lab equipment, manufactures these funnels. This particular model, with its generous 1000mL capacity and standardized ground glass fittings, promises efficient and reliable separation.
My work in remote, mobile labs for environmental sampling often requires on-site extraction. Finding a rugged, reliable separatory funnel that could withstand the rigors of transport and field use while still providing lab-grade accuracy was a challenge. Many plastic funnels proved too fragile, and cheaper glass options lacked the precision ground fittings needed for volatile solvents.
Unboxing the Kimble/Kontes KIMAX Separatory Funnel was a reassuring experience. The heavy-walled glass felt substantial, not flimsy. The ground glass stopper and stopcock exhibited a smooth, tight fit, inspiring confidence in leak-proof operation.
Compared to a cheaper, no-name separatory funnel I’d previously used (and promptly shattered) and a plastic model with a leaky valve, the Kimble/Kontes funnel stood out immediately. The Kimble/Kontes offered a level of precision and durability that the others simply couldn’t match. The plastic one contaminated samples, and the cheap glass one spontaneously broke when being cleaned.
My first impression was excitement mixed with relief. Finally, a separatory funnel that felt like it could handle the demands of field work and still deliver accurate results. It felt like a substantial investment in the quality and reliability of my work.
Real-World Testing: Putting Kimble/Kontes KIMAX Separatory Funnels, Squibb, Pear-Shaped, Kimble Chase 29048 1000 With ST Ground Glass Stopper And ST Ground Glass Stopcock to the Test
First Use Experience
My initial testing took place during a water quality assessment in a remote mountain stream. We needed to extract organic pollutants from large water samples on-site. The rugged terrain and variable weather demanded robust equipment.
The Kimble/Kontes Separatory Funnel performed flawlessly, even in slightly damp conditions. The ground glass stopper prevented any leakage while vigorously shaking the funnel. The stopcock offered fine control over the drainage rate, crucial for cleanly separating the layers.
The funnel proved incredibly easy to use, even with gloved hands. The pear-shaped design allowed for effective mixing and clear visibility of the interface between the two liquid phases. No issues arose during the extraction process, and the resulting separation was clean and efficient.
Extended Use & Reliability
After several months of regular use in various field locations, the Kimble/Kontes KIMAX Separatory Funnel continues to perform admirably. The glass shows no signs of etching or clouding, even after repeated exposure to harsh solvents. The ground glass fittings remain tight and leak-free.
Despite being transported in a padded case, the funnel has endured some bumps and jolts without any damage. This speaks volumes about the quality of the glass and the overall construction. Cleaning is straightforward; a simple rinse with solvent followed by soap and water is sufficient.
Compared to previous experiences with less robust funnels, the Kimble/Kontes model has been a revelation. It has eliminated the frustration and potential errors associated with leaky valves, fragile glass, and contaminated samples. This has improved efficiency and quality of the research being conducted.
