A Close Look at the Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000
The Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000 is not your typical piece of outdoor gear. Manufactured by Kimble/Kontes, this 2000ml separatory funnel is designed for laboratory use, specifically for separating liquids of different densities. Its pear-shaped design, large lower stem, and robust construction promise efficient and reliable separation, making it a staple for scientific applications.
My work frequently requires separating liquids in field labs under austere conditions. I needed a reliable, relatively large-capacity separatory funnel that could withstand the rigors of transport and frequent use. The Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000 seemed like a suitable option, given Kimble/Kontes’s reputation for quality glassware.
Upon unboxing, the first thing I noticed was the solid construction of the funnel. The glass felt thick and durable, and the pear shape appeared well-formed and balanced. The listed “Uniformly heavy walls, fire-polished and chip-resistant stems, and heavily beaded rims” seemed to hold true.
I considered other 2000ml separatory funnels from brands like Pyrex and Corning. Ultimately, I chose the Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000 due to its advertised stem design facilitating more complete separation. The large lower stem diameter was a crucial selling point for my needs.
Initially, I was cautiously optimistic. The price point seemed high, but if the funnel lived up to its claims of durability and efficient separation, it would be a worthwhile investment. The Kimble/Kontes name certainly carries weight in the scientific community, contributing to my initial excitement.
Real-World Testing: Putting Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000 to the Test
First Use Experience
My first use case involved separating oil contaminants from water samples collected during a simulated oil spill response exercise. The test was conducted outdoors in moderately windy conditions, with temperatures around 65°F. Setting up the Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000 was straightforward.
The large capacity made handling the 2000ml volume relatively easy, even with gloved hands. The separation process itself was efficient. The large stem diameter allowed for rapid drainage of the lower aqueous layer, and the pear shape facilitated a clean separation of the oil layer.
I did find that controlling the flow rate with the stopcock (not included) required some finesse. This is because this model does not include a stopcock or stopper, so it must be purchased separately.
Extended Use & Reliability
After several weeks of using the Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000 in various field tests, it has held up remarkably well. There are no signs of cracks or chips despite being transported in a moderately padded container. Cleaning the funnel after each use has been relatively simple.
A quick rinse with solvent followed by soap and water has been sufficient to remove all residue. Compared to previous funnels I’ve used with narrower stems, the Kimble/Kontes model’s wider stem is significantly easier to clean thoroughly. Its durability and ease of cleaning exceeded my expectations.
Breaking Down the Features of Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000
Specifications
- Capacity: 2000ml. This generous volume is ideal for processing larger samples, reducing the number of separation cycles required.
- Shape: Squibb, Pear-Shape. The pear shape optimizes the separation process by promoting clear layer formation.
- For Stopcock Size: 6 (Stopcock NOT Included). The user must procure a compatible stopcock separately.
- Stopper Number: 38 (Stopper NOT Included). Like the stopcock, the stopper must also be purchased separately.
- Material: KIMAX Borosilicate Glass. KIMAX glass ensures chemical resistance and thermal stability.
- Stem: Large lower stem diameter. This feature allows for a faster and more complete separation process.
- Construction: Uniformly heavy walls, fire-polished, chip-resistant stems, heavily beaded rims. These contribute to the funnel’s overall durability and longevity.
These specifications matter because they directly impact the funnel’s performance and user experience. The 2000ml capacity allows for handling larger volumes, while the pear shape promotes efficient layer separation. The KIMAX glass ensures the funnel can withstand exposure to various chemicals and temperature fluctuations without degradation.
Performance & Functionality
The Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000 performs its primary function of separating liquids exceptionally well. Its large lower stem ensures a rapid and complete draining of the bottom layer, minimizing the risk of cross-contamination. The pear shape contributes to cleaner separations compared to cylindrical funnels I have used.
The need to purchase a stopcock and stopper separately is a notable weakness. This adds to the overall cost and introduces the potential for compatibility issues if the wrong size is selected. The funnel meets my expectations for separation efficiency and durability.
Design & Ergonomics
The Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000 is constructed from high-quality KIMAX borosilicate glass. Its weight is substantial, which inspires confidence in its durability. The pear shape, while functional, is not particularly ergonomic for prolonged handling.
There is no significant learning curve associated with using this funnel. Basic familiarity with separatory funnel operation is sufficient.
Durability & Maintenance
The heavy-walled KIMAX glass construction suggests the Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000 should last for years with proper care. Its chemical resistance minimizes the risk of degradation from harsh solvents. Cleaning is straightforward, further enhancing its long-term usability.
Minor chips on the stem are possible with rough handling, but the fire-polished and chip-resistant stem helps to mitigate this risk.
Accessories and Customization Options
No accessories are included with the Kimble/Kontes Funnel (REPLACEMENT)2000 Ml 29048G-2000, aside from the funnel itself. Users must purchase a size 6 stopcock and size 38 stopper separately. Compatibility with other brands’ accessories depends on adherence to standard laboratory glassware dimensions.
