How I Used the Kimble/Kontes KIMAX Separatory Funnels, Squibb, Pear-Shaped, Kimble Chase 29048 1000 With ST Ground Glass Stopper And ST Ground Glass Stopcock and What I Found
The Kimble/Kontes KIMAX Separatory Funnels, Squibb, Pear-Shaped, Kimble Chase 29048 1000 With ST Ground Glass Stopper And ST Ground Glass Stopcock is a laboratory staple, designed for liquid-liquid extraction. Manufactured by Kimble Chase, this funnel features a pear-shaped design, a standard taper ground glass stopper, and a standard taper ground glass stopcock.
My journey with this particular model began with a need for a reliable, high-capacity separatory funnel for field testing water samples. I needed to extract contaminants from various water sources encountered during extended backcountry survival training exercises. The primary issue was the inconsistent performance of cheaper plastic funnels and the smaller capacities of other glass alternatives I had used.
Upon unboxing, the immediate impression was one of quality and robustness. The KIMAX glass felt substantial, and the ground glass joints were meticulously crafted. It was clear this wasn’t some flimsy piece of labware; it was a tool designed for serious use.
Compared to other funnels I’ve used, like the Corning Pyrex separatory funnel with a PTFE stopcock, or cheaper plastic funnels common in introductory chemistry kits, the Kimble/Kontes stood out. The Kimble/Kontes offers a superior build quality, larger capacity, and the reliability of ground glass joints, whereas the plastic options were prone to leaking and degradation over time, and the smaller glass options required multiple extraction steps. This efficiency was critical.
My initial excitement was tempered with a slight apprehension about transporting such a delicate piece of equipment into the field. However, the heavy-walled construction instilled confidence in its ability to withstand the rigors of outdoor use, provided it was packed carefully.
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 first field test involved extracting potential contaminants from river water during a survival training exercise in the Cascade Mountains. The funnel was used to separate organic compounds from the water samples, using a solvent.
The Kimble/Kontes performed admirably, even in the challenging conditions of a makeshift outdoor lab. The ground glass stopper and stopcock provided a secure seal, preventing leaks even when the funnel was vigorously shaken to enhance the extraction process. I didn’t require any grease to get a good seal.
The ease of use was notable; the large 1000mL capacity meant fewer extraction cycles were needed for larger samples. The pear-shaped design aided in clean separation, allowing for precise control during drainage. There were no issues encountered in the first use.
Extended Use & Reliability
After several months of intermittent use in diverse environments, including humid coastal regions and arid desert landscapes, the Kimble/Kontes funnel has proven its durability. The KIMAX glass has shown no signs of degradation, even after repeated exposure to various solvents and temperature fluctuations.
There are no noticeable signs of wear and tear on the glass itself. The ground glass joints maintain their tight seal, which is essential for accurate extractions.
Maintenance involves thorough cleaning with appropriate solvents and detergents, followed by careful drying to prevent water spots or residue buildup. The funnel is easy to clean due to its smooth glass surfaces. It has significantly outperformed my previous experiences with plastic funnels that became brittle and discolored after prolonged use.
