Hands-On with the Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500
In my line of work, getting precise separations is critical. That’s why I was particularly excited to get my hands on the Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500, a chromatography column designed for color-coded separations. Kimble/Kontes, a well-respected name in laboratory equipment, promises an inexpensive and easy way to separate color-coded materials.
As someone who frequently works with field samples that need rapid analysis, I was looking for a chromatography solution that offered both precision and portability. I needed something that could handle various environmental conditions without compromising the integrity of my separation process. The Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 piqued my interest because it claims to offer just that, all while being easy to store and use.
Upon unboxing, my initial impression was positive: the column felt robust and well-constructed. The PTFE (TFE) material gave it a solid feel, suggesting it could withstand regular use and exposure to various chemicals. Compared to the glass columns I’ve used in the past, this one seemed less prone to breakage, which is a huge plus for field applications.
I’ve previously used similar chromatography columns from Ace Glass and Chemglass, but they often lacked the specific color-coding feature touted by this Kimble/Kontes model. The Ace Glass columns, while reliable, required manual labeling, adding a margin for error. The Chemglass option was often more expensive without a noticeable performance benefit. I chose the Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 hoping the color-coding would streamline my workflow and reduce the risk of misidentification.
My first impression was one of cautious optimism. While the construction seemed promising, the real test would be its performance in the field. I was eager to see if it could live up to the claims of ease-of-use and efficient separation.
Real-World Testing: Putting Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 to the Test
First Use Experience
My first test of the Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 was during a field study at a remote environmental monitoring site. I needed to separate various color-coded copper strips from samples extracted from soil. The conditions were moderately humid with temperatures around 75°F.
The column was relatively easy to set up, but I quickly realized the description’s statement about the color-coded application was vague. It took some trial and error to figure out how to effectively introduce the color-coded copper strips and maintain consistent separation. Initially, I tried using a standard purge gas, as the description mentioned, but quickly realized that was not the way to go.
After a few failed attempts, I found that carefully layering the sample and using a slow, steady flow of solvent gave the best results. The biggest surprise was the lack of included instructions for optimal solvent usage with color-coded separations, making it a steep learning curve.
Extended Use & Reliability
After several weeks of regular use, the Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 has proven to be relatively durable, but with some caveats. The PTFE material holds up well to most solvents, showing no signs of degradation. However, the lack of a proper support rack has become a persistent issue.
The column itself hasn’t shown any signs of wear and tear, but keeping it stable during operation is challenging without a dedicated rack (which, as the product description notes, is not included). Cleaning is straightforward, requiring only a thorough flush with an appropriate solvent after each use. Compared to the fragility of glass columns, this is a significant improvement.
In terms of performance compared to previous experiences, the color-coding aspect, once understood, does offer a degree of convenience, but I wouldn’t say it’s a game-changer. Ultimately, a well-labeled glass column can achieve similar results with proper technique.
Breaking Down the Features of Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500
Specifications
The Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 has the following specifications:
- Description: COL CHROM TFE STP CS1 19X500MM
- Material: PTFE (TFE)
- Dimensions: 19mm diameter x 500mm length
The 19mm diameter provides a decent separation capacity for most analytical needs. The 500mm length allows for adequate resolution of components. The PTFE construction ensures chemical resistance and reduces the risk of contamination.
Performance & Functionality
The Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 performs adequately once the user understands its quirks, particularly with solvent selection and flow rate. Its strength lies in its ability to handle a variety of solvents and its relatively inert nature. The separation efficiency is on par with similarly sized columns, but not exceptional.
One significant weakness is the lack of clear guidance on optimizing color-coded separations, necessitating experimentation. It meets basic expectations for chromatographic separation, but it doesn’t exceed them.
Design & Ergonomics
The PTFE construction is a definite plus for durability, and the column is relatively lightweight. However, the absence of a proper stand or rack is a major oversight. Securing the column during operation can be cumbersome, especially in a field setting.
The design lacks certain user-friendly features like integrated flow control or a clear visual indicator for separation progress. There is a definite learning curve in terms of solvent and color-coded sample introduction.
Durability & Maintenance
The Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 should last a considerable amount of time with proper care. PTFE is known for its resistance to chemical degradation. Maintenance involves cleaning with an appropriate solvent after each use, and ensuring it is stored properly to prevent deformation.
Given the simple design, there are few components that could fail, making repairs unlikely.
Accessories and Customization Options
The Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 comes with very limited accessories. It’s essentially the column itself. You’ll need to purchase a stand or rack separately, as well as any necessary connectors and tubing.
Customization is limited to choosing appropriate solvents and packing materials. It’s compatible with standard chromatography fittings, allowing you to connect it to various pumps and detectors.

Who Should Buy Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500?
The Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 is perfect for environmental scientists, field researchers, or lab technicians who need a durable and chemically resistant chromatography column. It’s best suited for those who are already familiar with chromatography techniques and willing to experiment to optimize the color-coded separation process.
This product is not ideal for beginners or those seeking a ready-to-use solution with comprehensive instructions and accessories. People who prefer a simpler setup or require very high-resolution separations might also want to consider alternative options.
A must-have accessory is a compatible stand or rack to stabilize the column during operation. A selection of appropriate solvents based on the target compounds is also essential.
Conclusion on Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500
The Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 is a decent, but not exceptional, chromatography column. Its strength lies in its durability and chemical resistance, making it suitable for field applications. However, the lack of clear instructions and the absence of a necessary stand detract from its overall value.
At $203.99, the price is justified for the material and construction, but it feels incomplete without a stand or rack. I would personally recommend it to experienced chromatographers who value durability and are willing to invest time in optimizing the separation process, but only with the caveat that they’ll need to purchase additional accessories.
If you are comfortable with a DIY approach and prioritize a robust column over a user-friendly experience, then the Kimble/Kontes Col Chrom Tfe Stp CS1 19X500MM 17800-19500 might be a worthwhile addition to your lab or field kit. Just be prepared to roll up your sleeves and figure out the specifics yourself.
