Tube Characteristics

Probe & Tube Characteristics

For over 40 years, International Tube has helped instrument designers, R&D teams, and OEMs transform raw stainless-steel and specialty-alloy tubing into mission-critical probes, cannulae, and fluid-path assemblies. Whether you need a single prototype or a fully validated production run, our vertically integrated facility—cutting, bending, CNC machining, grinding, swaging, laser welding, finishing—delivers leak-free components that accelerate time-to-market and reduce total cost.

Key Tube Characteristics

1. Size & Internal Volume

OD Range: 0.003 – 0.625 in (0.08 – 15.9 mm)
ID & Wall: Standard, thin-wall, and ultra-thin options balance flow rate, pressure rating, and flexibility.
Why It Matters: Dimensions dictate sample volume, clearance, and carry-over.

2. Materials & Alloys

304/304L & 316/316L stainless steels
Titanium, Inconel 625, brass, and other specialty alloys
Why It Matters: Corrosion resistance, biocompatibility, chemical compatibility, temperature tolerance.

3. Wall Thickness & Strength

Choose standard or custom wall gauges to meet burst-pressure, bend-radius, and weight targets.

4. Surface Finish & ID Cleanliness

As-drawn, mechanically polished, electropolished, or ID flow-honed
Optional PTFE, Parylene, or hydrophobic coatings for ultra-low carry-over

5. Tip Geometries

Blunt, beveled, conical, ball, swaged, or fully machined tips optimize aspiration, dispense, or penetration performance.

6. Connection Interfaces

Barbs, luer locks, tapers, flares, threaded flanges, and custom ferrules ensure quick, leak-free integration into your system.

7. Mounting & Assembly Options

Integral collars, blocks, adapters, or multi-piece constructions—laser-welded or brazed—for drop-in installation.

8. Specialty Features & Secondary Operations

Side ports, vent holes, anti-bubble grooves
CNC-milled flats, slots, and keyways
Laser marking for traceability

Probe Characteristics Checklist

Characteristic	Why It Matters	How International Tube Helps
Tube Size & Alloy	Controls volume, flow, clearance, and chemical compatibility.	Hundreds of miles of stock in standard and custom IDs/ODs; rapid alloy matching from 300-series stainless to high-nickel super-alloys.
Tip Geometry	Affects aspiration angle, dispense accuracy, and sample integrity.	Integrated swaging, form-grinding, and Swiss CNC machining deliver burr-free, flow-tuned tips in one setup.
Connection Style	Ensures leak-free, quick-disconnect integration.	Precision CNC adds barbs, luer locks, threads, flanges, or custom ferrules matched to your mating hardware.
Mounting Strategy	Guarantees positional accuracy and simplifies service.	Laser-welded collars, brazed blocks, or bracketed adapters ship ready to bolt straight into your instrument.
