Catalog Number - 47240-50

47240-50 ARE‑Applied Research PTFE Tubing is a high‑purity, low‑pressure fluid transfer solution engineered for HPLC, UHPLC, LC‑MS, and general laboratory applications, delivering higher flow capacity through a larger internal diameter, along with black pigmentation for visual line identification in organized systems.

Manufactured from 100% virgin PTFE resin, this tubing contains no additives or plasticizers, except for trace pigment used solely for visual differentiation, ensuring low extractables and compatibility with sensitive analytical workflows.

Precision Dimensions – High Flow Optimization

• Inner Diameter (ID): 0.020" (0.50 mm)

• Outer Diameter (OD): 1/16" (1.6 mm)

• Wall Thickness: 0.55 mm

• Tolerance (ID & OD): ± 0.10 mm

✅ Larger ID provides higher flow rates and reduced backpressure compared to smaller ID tubing

Black Pigmentation – Visual Line Identification

• Black‑pigmented PTFE tubing

• Supports:

  • Visual differentiation of fluid paths

  • Improved system organization

  • Faster troubleshooting and maintenance

✅ Intended for visual identification only (not functional color coding)

Low‑Pressure Chromatography Performance

• Designed for low‑pressure fluid paths, including:

  • Pre‑pump mobile phase delivery

  • Post‑detector solvent waste lines

  • General solvent transfer

• Pressure Rating: 725 psi (49.9 bar)

✅ Ideal for higher flow and extended routing applications

Virgin PTFE Construction – High Purity & Inertness

• Manufactured from 100% virgin PTFE

• No additives (except trace pigment)

• Chemically inert and non‑reactive

✅ Minimizes contamination in LC‑MS and trace‑level analytical workflows

Broad Chemical & Thermal Resistance

• Resistant to:

  • Organic solvents

  • Acids and bases

  • Aqueous mobile phases

• Maximum Temperature: 260 °C

✅ Suitable for demanding and elevated‑temperature laboratory environments

Micro‑Porous Structure – Application Consideration

• PTFE tubing contains micropores allowing slight gas exchange

• Important when working with:

  • Degassed solvents

  • Oxygen‑sensitive workflows

✅ Consider alternative tubing where gas impermeability is critical

Flexible & Durable Design

• Flexible for easy routing and installation

• Durable under repeated lab use

• Maintains clear visual distinction in multi‑line systems

✅ Supports efficient system setup and maintenance

Regulatory Compliance

• Compliant with:

  • RoHS EU Directive 2011/65/EU

  • Amendment (EU) 2015/863

✅ Meets global environmental and safety standards

Available Length Options

✅ Select the correct length for your application:

• 5 meter roll (this item)

• 1 meter roll

• 3 meter roll

• 10 meter roll

• 25 meter roll

✅ Custom cut lengths available through Customer Service

Typical Applications

• HPLC mobile phase delivery (pre‑pump)

• High‑flow solvent routing

• Solvent waste systems

• Multi‑line fluid systems requiring visual differentiation

• OEM and instrument integration

Important Usage Notes

• Not intended for high‑pressure HPLC pump head connections

• Black pigmentation is for visual identification only

• Consider permeability when using degassed or oxygen‑sensitive solvents

• Ensure proper fittings for secure, leak‑free connections
