Catalog Number - 49210-70-3M

49210-70-3M 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 minimal wall thickness for extremely low flow resistance.

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.

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

✅ Very large ID and ultra‑thin wall provide maximum flow capacity and minimal pressure drop

Thin‑Wall Construction – Maximum Flow Efficiency

• Ultra‑thin wall minimizes material resistance

• Enables rapid solvent movement and unrestricted flow

• Best suited for low‑pressure and gravity‑assisted systems

✅ Ideal for applications where minimizing flow restriction is critical

Low‑Pressure Chromatography Performance

• Designed for low‑pressure applications, including:

  • Pre‑pump solvent routing

  • Post‑detector waste lines

  • Bulk solvent transfer and venting

• Pressure Rating: 150 psi (10.3 bar)

✅ Suitable for very low‑pressure systems only

⚠️ Handling Caution – Ultra‑Thin Wall Design

• Extremely thin wall (0.15 mm)

• Easily kinked, crushed, or damaged

✅ Handle with care during:

• Installation

• Cutting

• Routing

✅ Avoid tight bends and excessive mechanical stress

Virgin PTFE Construction – High Purity & Inertness

• Manufactured from 100% virgin PTFE

• No additives (except trace identification particles)

• Chemically inert and non‑reactive

✅ Ensures minimal contamination in LC‑MS and trace analysis

Broad Chemical & Thermal Resistance

• Resistant to:

  • Organic solvents

  • Acids and bases

  • Aqueous solutions

• Maximum Temperature: 260 °C

✅ Suitable for aggressive solvents and elevated temperatures

Micro‑Porous Structure – Application Consideration

• PTFE contains micropores allowing gas exchange

• Important for:

  • Degassed solvents

  • Oxygen‑sensitive workflows

✅ Consider alternative tubing when gas impermeability is required

Flexible & Lightweight Design

• Lightweight and flexible for low‑stress routing

• Natural translucent color allows flow visibility

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

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:

• 3 meter roll (this item)

• 1 meter roll

• 5 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 backpressure

• General laboratory fluid handling

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 prevent mechanical damage
