Catalog Number - 49210-70-C

49210-70-C 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, offering a large internal diameter combined with extremely minimal wall thickness to deliver maximum flow capacity with minimal resistance, even across extended runs.

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

Supplied on a convenient 25 meter spool, ideal for bulk lab use, custom installations, and OEM system design.

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 enables maximum flow rates with near-zero restriction

Thin‑Wall Construction – Maximum Flow Efficiency

• Ultra‑thin wall minimizes resistance to fluid movement

• Supports fast solvent transfer and high‑volume throughput

• Ideal for long, low‑pressure flow paths and venting systems

✅ Optimized for applications where flow restriction must be minimized

Low‑Pressure Chromatography Performance

• Designed for very low‑pressure applications, including:

  • Pre‑pump solvent delivery

  • Post‑detector waste lines

  • Bulk solvent transfer and venting

• Pressure Rating: 150 psi (10.3 bar)

✅ Suitable only for low to very low‑pressure systems

⚠️ Handling Caution – Ultra‑Thin Wall Design

• Extremely thin wall (0.15 mm)

• Susceptible to:

  • Kinking

  • Flattening

  • Mechanical damage

✅ Handle carefully during:

• Installation

• Cutting

• Routing

✅ Avoid sharp bends, compression, and unsupported spans

Virgin PTFE Construction – High Purity & Inertness

• Manufactured from 100% virgin PTFE

• No additives or plasticizers (other than trace identification particles)

• Chemically inert and non‑reactive

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

Broad Chemical & Thermal Resistance

• Resistant to:

  • Organic solvents

  • Acids and bases

  • Aqueous mobile phases

• Maximum Temperature: 260 °C

✅ Suitable for aggressive chemical environments and elevated temperatures

Micro‑Porous Structure – Application Consideration

• PTFE tubing contains micropores allowing gas exchange

• Important when working with:

  • Degassed solvents

  • Oxygen‑sensitive systems

✅ Consider alternative tubing when gas impermeability is required

Flexible & Lightweight Design

• Lightweight and flexible for low‑stress routing

• Natural translucent appearance allows visual monitoring of flow

✅ Ideal for non‑pressurized and low‑pressure fluid systems

Convenient Spool Format – High Volume Efficiency

• Supplied on a 25 meter spool

• Ideal for:

  • Bulk usage

  • Custom cut lengths

  • OEM manufacturing

✅ Reduces handling complexity and improves workflow efficiency

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:

• 25 meter spool (this item)

• 1 meter roll

• 3 meter roll

• 5 meter roll

• 10 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

• Extended solvent waste routing

• General laboratory fluid handling

Important Usage Notes

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

• Not suitable for moderate or high‑pressure systems

• Consider permeability when using degassed or oxygen‑sensitive solvents

• Use proper routing support to minimize mechanical stress
