• PEEK Column Coupler delivers a low swept-volume connection while maintaining column efficiency.
• Our couplers are an excellent option for reducing overall flow path volume while coupling two devices together.
• It is manufactured from biocompatible PEEK giving is excellent chemical resistance to virtually all commonly used solvents.
• It has a swept volume of 3.6uL, a thru-hole of .010″ and a male to male thread configuration of 10-32 Coned.

• Sealing Concrete Columns:Column end plugs are used to seal the ends of concrete columns, preventing moisture from entering and potentially damaging the concrete.
• Aesthetics and Safety:They can also improve the appearance of the columns and protect people from sharp edges. 

• HPLC:In HPLC, zero dead volume unions are used to connect the column to the detector and other system components, ensuring that the separated compounds are delivered to the detector without dilution or band broadening caused by mixing in the connection.
• GC (Gas Chromatography):Similar to HPLC, zero dead volume unions are used in GC systems to minimize band broadening and ensure accurate analysis.
• Column Connections:They are also used to connect different columns or column sections, especially when using specialized column configurations. 

• Analytical and Process Systems:In any system where precise fluid flow and mixing are critical, zero dead volume unions are preferred. This includes various research and industrial applications. 
• Gas and Liquid Systems:They are suitable for both gas and liquid applications, where maintaining a consistent flow and preventing cross-contamination is important. 
• High-Pressure Applications:Many zero dead volume unions are designed to withstand high pressures, making them suitable for applications like supercritical fluid chromatography. 

• Research and Development:Zero dead volume unions are widely used in research labs for various experiments requiring precise fluid handling.
• Quality Control:They are also used in quality control labs for ensuring the accuracy and reliability of analytical measurements. 

• Minimized Dead Volume:The primary benefit is the elimination of dead volume, which is the volume within the connection that can cause mixing and band broadening.
• Improved Peak Shape and Resolution:By minimizing dead volume, zero dead volume unions help improve peak shape and resolution in chromatographic analyses.
• Accurate Measurements:They ensure that the sample reaches the detector without significant dilution or distortion, leading to more accurate and reliable measurements.
• Reduced System Contamination:By minimizing the areas where fluids can stagnate, they help reduce system contamination.
• Enhanced System Performance:By optimizing fluid flow and minimizing band broadening, they contribute to the overall performance of analytical and process systems. 

• Stainless steel filter, solvent inlet, 12–14 µm For HPLC

Color-coding identifies the ID of your 1/16" OD PEEK tubing – each ID is coded with a different color.

PEEK tubing has the strength required to withstand continuous use at HPLC pressure without swelling or bursting, and is not affected by halide salts, high strength buffers, or other aggressive mobile phases that corrode stainless steel. The polymer surface will not leach metal ions into the eluent or extract metal-sensitive components from the sample. Note however that dichloromethane, THF, and DMSO may cause swelling in PEEK, and concentrated nitric and sulphuric acid will attack PEEK.

Tolerance is ±.0005" for IDs up to .010", and ±.001" for larger IDs.

• Temperature Control:HPLC column ovens provide a controlled environment for the column, allowing users to set and maintain a specific temperature. 
• Reproducibility:Consistent temperature leads to consistent retention times, peak shapes, and separation efficiency, making results more reliable and reproducible. 
• Optimizing Separations:Temperature can be adjusted to improve separation efficiency, reduce analysis time, or optimize the separation of specific compounds. 

• Temperature Range:Most HPLC column ovens can heat from slightly above ambient temperature up to 100°C or even 200°C. Some can also cool the column below ambient temperature. 
• Temperature Control:PID (Proportional-Integral-Derivative) controllers are commonly used to precisely regulate and maintain the set temperature. 
• Stability:Modern ovens offer high stability, often within +/- 0.1°C, ensuring consistent results. 
• Safety Features:Many ovens include features like leak detection, over-temperature protection, and sensor fail/break indication for safe operation. 
• Heating and Cooling:Some ovens can both heat and cool the column, allowing for a wider range of applications and method development. 
• Dual Leak Sensors:Some ovens, like the HCO -02 Slim Line, have dual leak sensors to detect mobile phase leaks. 
• Preheating:Optional preheating systems can warm the sample band and mobile phase in the column inlet tubing to match the set oven temperature. 
• Column Switching:Some ovens can accommodate multiple columns and switching valves for different analysis options. 

• Pharmaceutical Analysis:HPLC column ovens are widely used in pharmaceutical research and quality control for analyzing drug compounds, determining drug purity, and studying pharmacokinetics. 
• Environmental Analysis:They are also used in environmental analysis, such as detecting contaminants in soil and groundwater. 
• Food and Beverage Industry:HPLC is used for quality control and analysis in the food and beverage industry. 
• Biopharmaceutical Applications:They play a role in the analysis and purification of biomolecules. 
• Method Development:Column ovens are essential for optimizing HPLC methods, including selecting the appropriate temperature for a given separation. 

Our PEEK Tees and Crosses are precisely designed to withstand environmental stresses in the high-pressure regions of a system. It is manufactured from inert PEEK, which delivers excellent chemical resistance. Featured are our PEEK Micro Tees and Crosses that join capillary tubing together. Several researchers use our PEEK MicroTee to introduce fluid to their stream just prior to a Mass Spectrometer because of its advantageous internal geometry and PEEK polymer’s electrical resistance.
