Labasics Glass Chromatography Column, 24/40 Joint, 300 mm
This Labasics column features a 24/40 outer joint at the top, a fritted disc, and a PTFE stopcock. With a 30 mm column outer diameter and a 300 mm effective length, it supports in-column operations for a range of chemical experiments. The borosilicate glass construction is designed to resist typical solvents used in chromatography, while the fritted disc helps distribute the solvent evenly during separation. The standard joint size ensures compatibility with common lab setups and adapters.
Labasics Glass Chromatography Column, 11.8 Inch
This longer Labasics column emphasizes extended separation capability with an 11.8 inch effective length. It maintains a 24/40 standard taper outer joint, allowing easy integration into established setups. A fritted disc and PTFE stopcock support controlled flow and efficient separation. Its larger overall length can accommodate more complex sample matrices, making it suitable for multi-stage or high-volume lab workflows while preserving chemical compatibility with common reagents.
stonylab Glass Chromatography Column, 300 mm
This stonylab column offers a 40 mm outer diameter with a 300 mm effective length, paired with a 24/40 standard taper top joint. It includes a fritted disc and a PTFE stopcock for efficient sample loading and flow control. The larger diameter provides greater column volume, which can improve separation resolution for complex mixtures. Borosilicate glass delivers thermal stability and chemical inertness in typical chromatography environments.
Labasics Glass Chromatography Column, 11.8 Inch (OD 1.97 Inch)
The Labasics column in this variant features a 1.97 inch outer diameter with an 11.8 inch effective length, preserving the fritted disc and PTFE stopcock. This configuration balances column volume with manageable handling in routine separations. The standard 24/40 taper joint ensures compatibility with common lab hardware, while the borosilicate glass construction minimizes interaction with many solvents and samples. It is suited for laboratories requiring reliable performance across mid-sized workflows.
stonylab Chromatography Column, 1 Inch ID, 18 Inch Length
This stonylab column offers a 1 inch inner diameter and 18 inch effective length, with a 24/40 standard taper upper joint and a G2 sand plug at the base. The sand plug helps control flow patterns and supports effective separation of complex mixtures. Built from borosilicate glass, the column provides good thermal resistance and chemical inertness for a range of lab applications, including high-precision liquid separations.
stonylab Glass Chromatography Column, 300 mm, 50 mm OD
This stonylab column features a 50 mm outer diameter and 300 mm effective length, with a 24/40 standard taper top joint, fritted disc, and PTFE stopcock. The larger diameter increases column capacity and potentially improves separation for sizable samples. The construction prioritizes durability and chemical compatibility, making it suitable for routine and demanding chromatography tasks in educational or research settings.
Kimble Flex-Column 420401-1505
The Kimble Flex-Column provides an economical chromatography option with a compact volume (9 ml), a 1.5 cm inner diameter, and a 5 cm length. It features a standard 24/40 join and is appropriate for small-scale experiments, rapid testing, or educational demonstrations. Although smaller in size, its quality borosilicate glass construction helps ensure stable performance with various solvents, offering a cost-effective entry point for basic separations.
stonylab Chromatography Column, 1 Inch ID, 18 Inch Length
This stonylab column combines a 1 inch inner diameter with an 18 inch effective length and features a G2 sand plug at the base for controlled flow. The borosilicate glass construction contributes to durability and solvent compatibility, while the 24/40 joint allows straightforward integration with standard laboratory equipment. It is well-suited for high-precision liquid separations where column volume and stable performance are important.
Buying Guide: Key purchase considerations
- <strongColumn diameter and length: Larger diameters and longer columns increase capacity and resolution but require more space and higher pressure tolerance. Choose based on sample size and separation complexity.
- <strongJoint size and compatibility: Most listed columns use a 24/40 outer joint, a common standard. Ensure compatibility with existing adapters, clamps, and receivers in your setup.
- <strongFritted disc design: A uniform frit helps distribute solvent evenly and supports effective sample contact with the stationary phase. Check disc porosity and material.
- <strongStopcock material: PTFE stopcocks offer chemical resistance and smooth operation, reducing sample loss during flow control.
- <strongMaterial and durability: Borosilicate glass provides thermal resistance and chemical inertness. Consider handling, cleaning, and solvent compatibility in your lab.
- <strongSand plugs and base features: Some models include G2 sand plugs to improve flow control at the base, which can enhance separation for certain mixtures.
- <strongApplications and scale: For teaching or light analytical work, smaller or economical models may suffice. For research or production-scale separations, higher capacity columns are preferable.
- <strongMaintenance and compatibility: Confirm ease of cleaning, availability of fritted discs, and compatibility with your solvent portfolio to minimize downtime.
