Catalog Number - 49210-70

49210-70 ARE‑Applied Research PTFE Tubing is a thin‑walled, ultra‑high flow fluid transfer solution engineered for HPLC, UHPLC, LC‑MS, and general laboratory applications, delivering a large internal diameter combined with an extremely thin wall for minimal flow restriction and maximum solvent throughput.

Manufactured from 100% virgin PTFE resin, this tubing contains no additives or plasticizers (except trace particles for identification), ensuring low extractables and compatibility with sensitive analytical workflows.

Precision Dimensions – Ultra‑Low Restriction Flow Path

• Inner Diameter (ID): 0.066" (1.7 mm)

• Outer Diameter (OD): 0.080" (2.0 mm)

• Wall Thickness: 0.15 mm

• Tolerance (ID & OD): ± 0.20 mm

✅ Large ID with ultra‑thin wall delivers maximum flow capacity and near‑minimal pressure drop

Thin‑Wall Construction – Maximum Flow Efficiency

• Ultra‑thin wall reduces resistance to flow

• Enables rapid solvent transfer and efficient fluid movement

• Optimized for gravity feed and very low‑pressure systems

✅ Best suited for applications where flow restriction must be minimized

Low‑Pressure Chromatography Performance

• Designed for low‑pressure fluid paths, including:

  • Pre‑pump solvent routing

  • Post‑detector waste lines

  • Bulk solvent transfer and venting

• Pressure Rating: 150 psi (10.3 bar)

✅ Suitable exclusively for very low‑pressure applications

⚠️ Handling Caution – Ultra‑Thin Wall Design

• Extremely thin wall (0.15 mm)

• Easily kinked, flattened, or mechanically damaged

✅ Handle carefully during:

• Installation

• Cutting

• Routing

✅ Avoid sharp bends and compressive forces

Virgin PTFE Construction – High Purity & Inertness

• Manufactured from 100% virgin PTFE

• No additives (except trace identification particles)

• Chemically inert and non‑reactive

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

Broad Chemical & Thermal Resistance

• Compatible with:

  • Organic solvents

  • Acids and bases

  • Aqueous solutions

• Maximum Temperature: 260 °C

✅ Performs reliably in aggressive chemical and elevated temperature 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 materials when gas impermeability is required

Flexible & Lightweight Design

• Lightweight and flexible for low‑stress routing

• Natural translucent finish allows visual monitoring of flow

✅ Ideal for non‑pressurized and low‑pressure transfer lines

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 appropriate 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

• Gravity‑feed solvent systems

• Vent lines and gas exchange pathways

• Bulk solvent transfer at very low pressure

• Waste line routing with minimal resistance

• General laboratory fluid transfer

Important Usage Notes

• 🚨 Very thin wall – handle carefully to prevent kinking or collapse

• Not suitable for moderate or high‑pressure systems

• Consider permeability when using degassed or oxygen‑sensitive solvents

• Use proper support and routing to minimize stress
