Description
Product Overview
The Kimble Flex-Column 420401-2510 is engineered from premium borosilicate glass, a material celebrated for its exceptional chemical inertness and thermal stability. This construction ensures that the column can withstand aggressive solvents and high‑temperature gradients without compromising structural integrity, making it a dependable choice for demanding chromatographic protocols.
Measuring 49 ml in volume with a 2.5 cm internal diameter and a compact 10 cm length, the column delivers a balanced combination of capacity and efficiency. The reduced length minimizes dead volume while preserving sufficient interaction length for high‑resolution separations, allowing analysts to achieve sharp peaks and accurate quantitation across a variety of sample types.
Designed for seamless integration into existing liquid chromatography systems, the Flex-Column features standard fittings that align with common hardware configurations. This compatibility eliminates the need for adapters or extensive re‑engineering, enabling rapid deployment in both new installations and legacy setups.
Beyond its physical attributes, the column benefits from Kimble Chase’s rigorous quality control processes. Each unit undergoes meticulous inspection for dimensional accuracy, surface uniformity, and absence of defects, guaranteeing consistent performance batch after batch. This reliability translates into reduced downtime and lower operational costs for laboratories.
In addition to its core specifications, the Flex-Column is available in a range of sizes and colors to suit diverse experimental requirements. The 420401-2510 model, presented in a clean white finish, offers visual clarity for easy identification and inventory management, especially in busy research environments where multiple column types are in use.
Usage
This column excels in a broad spectrum of analytical applications, including pharmaceutical impurity profiling, environmental contaminant monitoring, and food safety testing. Its robust glass composition tolerates a wide pH range, allowing analysts to employ both reversed‑phase and normal‑phase methodologies without concern for column degradation.
For laboratories focused on high‑throughput screening, the compact 10 cm length reduces analysis time while maintaining resolution, enabling more samples to be processed within a given workday. The column’s low back‑pressure characteristics also make it suitable for use with older pump systems that may have limited pressure capabilities.
Researchers conducting method development will appreciate the column’s reproducibility, which facilitates systematic optimization of mobile phase composition, flow rates, and temperature settings. The consistent internal diameter ensures uniform flow distribution, a critical factor when fine‑tuning separation parameters for complex mixtures.

FAQ
What solvents are compatible with the Kimble Flex-Column?
The column is compatible with a wide range of organic solvents, including acetonitrile, methanol, tetrahydrofuran, and dichloromethane, as well as aqueous buffers spanning pH 1 to 14. Its borosilicate glass composition resists corrosion, allowing for versatile method development.
Can the column be reused after cleaning?
Yes, the Flex-Column can be regenerated using standard cleaning procedures such as flushing with strong solvents or applying a brief high‑temperature bake. Proper cleaning restores performance and extends the column’s usable lifespan.
What is the recommended storage condition for unused columns?
Unused columns should be stored in a dry, dust‑free environment at room temperature. Keeping them in their original packaging protects the glass from mechanical damage and maintains the integrity of the internal surface.
How does the column perform under high‑pressure conditions?
Thanks to its robust glass walls and precise machining, the Flex-Column tolerates pressures up to 400 bar without deformation. This capability supports high‑flow applications and ensures consistent chromatographic performance even under demanding operational settings.
Is there a warranty or guarantee for the column?
Kimble Chase offers a limited warranty covering manufacturing defects for a period of 12 months from the date of purchase. Should any issues arise, our customer service team will work with you to provide a replacement or appropriate solution.
