The IDEX PEEKsil Tubing, 1/32 in OD × 75 µm ID, 20 cm, 2/pk (37520; Cole-Parmer 02011-94) is a precut chromatography capillary combining a fused-silica fluid pathway with a mechanically strong PEEK outer covering. The black tubing has a 75 µm internal diameter, 1/32-inch outside diameter and maximum pressure rating of 15,000 psi.
Key Features
- Fused-silica internal fluid path, providing a rigid and consistent bore for analytical fluid handling
- Protective PEEK outer covering, adding mechanical strength and supporting reliable sealing with compatible fittings
- Narrow 75 µm internal diameter, providing the specified capillary flow path for this configuration
- Compact 1/32-inch outside diameter, matching compatible microfluidic and chromatography connections
- High 15,000 psi pressure capability, providing a verified maximum rating of 1,034 bar
- Low-adsorption fluid pathway, helping limit unwanted interaction between samples and the tubing surface
- Broad analytical chemical compatibility, supporting use with suitable chromatography solvents and mobile phases
- Factory-precut 20 cm lengths, supplied ready for installation without user cutting
- Black identification colour, making the 75 µm configuration easier to recognise within a fluidic system
- Convenient two-piece pack, providing two matching tubing lengths per package
Note: Do not cut PEEKsil tubing with conventional tubing cutters, as this can permanently damage the fused-silica core. Use the tubing only at its supplied precut length.
Benefits
- Combines the chemical and low-adsorption characteristics of fused silica with the strength of a PEEK outer layer.
- Provides a direct replacement option for conventional PEEK or stainless steel tubing in many compatible analytical systems.
- Supports high-pressure chromatography connections with a verified rating of up to 15,000 psi.
- Reduces installation preparation because each tube is supplied at a finished 20 cm length.
- Simplifies maintenance and identification through consistent dimensions and black colour coding.
Why Choose the IDEX PEEKsil Tubing, 1/32 in OD × 75 µm ID, 20 cm, 2/pk (37520; 02011-94)?
The IDEX 37520 PEEKsil tubing combines a tightly controlled fused-silica flow path with a durable PEEK covering for demanding analytical connections. Its 75 µm bore, compact 1/32-inch outside diameter and 15,000 psi pressure rating suit compatible high-pressure chromatography systems. John Morris Group can assist with matching unions, ferrules and other fluid-path fittings.
