EBOO Tubing Lines, Line Sets, and Kits: How Labs Spec the Right

How to spec EBOO tubing lines/line sets: sizing, connectors, pump segments, and reorder checklists for EBOO, EBO2, and EBO3 systems.

Why Getting "the Lines" Right Matters More Than You Think

If you have ever placed a reorder and simply told a supplier to "send the lines," you already know how that can go wrong. EBOO tubing lines are not generic — they vary by inner diameter, connector type, pump-segment durometer, and filter compatibility. Whether you run an EBOO, EBO2, or EBO3 platform, specifying the correct line set up front saves time, avoids returns, and keeps your research schedule on track.

This guide walks through the components that make up an EBOO line set, explains how to write a clear spec for reorders, and provides a checklist you can copy straight into a purchase request.

Anatomy of an EBOO Line Set

An EBOO line set (sometimes called an EBOO tubing kit) is a pre-assembled, single-use circuit. A typical kit includes:

  • Arterial and venous tubing runs — Medical-grade PVC or silicone lines that carry fluid from the access point, through the device, and back.
  • Pump segment — A reinforced section of tubing (sometimes called pump tubing) engineered to withstand repeated compression in a peristaltic pump head. Durometer, wall thickness, and ovality tolerances are tighter here than on the rest of the circuit.
  • PES membrane filter — The filtration element (e.g., PES H200 High Flux) housed in a rigid cartridge with standardized inlet/outlet ports.
  • Connectors and fittings — Luer-lock caps, barbed adapters, spike ports, and clamps that join segments and provide sampling or injection points.
  • Drip chamber / bubble trap (on some kits) — An inline chamber that removes air before fluid returns through the circuit.

Together, these components form a closed-loop circuit: fluid exits the reservoir, passes through the ozone generator and/or UV chamber, flows across the filter membrane, and returns — never exposed to the ambient environment.

Understanding EBOO Consumables vs. EBO2 and EBO3 Consumables

The terms EBOO consumables, EBO2 consumables, and EBO3 consumables often appear interchangeably online, but they are not always identical in spec. Key differences can include:

Inner Diameter (ID) and Flow Rate

Different device generations may use different pump-head sizes. A line set designed for a 2.5 L/hr device may have a smaller ID than one rated for 5 L/hr. Ordering the wrong ID can restrict flow (undersized) or allow excessive pulsation (oversized).

Connector Standards

Older EBOO platforms sometimes use barb-only fittings; newer EBO2 and EBO3 units may require luer-lock or bayonet connections. Mismatched connectors create leak points and compromise the closed-loop circuit.

Pump Segment Specifications

The pump segment is the single most wear-critical section of the circuit. It must match the pump-head roller diameter and gap. If the segment is too soft, it collapses prematurely; too stiff, and it resists compression, reducing flow accuracy. When sourcing replacement tubing, always confirm the pump-segment durometer and wall thickness against the device manufacturer's spec sheet.

Filter Compatibility

Not every filter cartridge fits every housing. The PES H200 High Flux membrane used in the EBOO O3 Research Device 2026 has specific port spacing, gasket dimensions, and pressure ratings. Substituting a filter from another product line risks leaks and unreliable data.

The Spec Checklist: What to Include in Every Reorder

Below is a checklist you can paste directly into an email or purchase order. Fill in the values from your device's technical manual:

  • Device make & model: (e.g., EBOO O3 Research Device 2026)
  • Kit part number or SKU (if known)
  • Tubing inner diameter (ID): _____ mm
  • Tubing outer diameter (OD): _____ mm
  • Pump segment length: _____ cm
  • Pump segment durometer: Shore A _____
  • Pump segment wall thickness: _____ mm
  • Connector type(s): Luer-lock / Barb / Bayonet / Other: _____
  • Filter membrane type: PES / Cellulose / Other: _____
  • Filter model: (e.g., H200 High Flux)
  • Filter port size: _____ mm
  • Sterilization method: EtO / Gamma / Autoclave-compatible
  • Quantity needed: _____
  • Preferred packaging: Individual / Multi-pack (e.g., 10-pack)

Providing this level of detail eliminates back-and-forth with suppliers and reduces the risk of receiving the wrong EBOO tubing kit.

Compatibility & Ordering: How to Avoid the "Just Send the Lines" Trap

Vague reorder requests are the number-one cause of wrong-part shipments. Here is how to avoid them:

1. Reference the Device Manual

Every reputable device comes with a consumables compatibility table. It lists the exact part numbers, dimensions, and materials for each replaceable component. Start there.

2. Use Measurable Specs, Not Brand Slang

Instead of "the regular lines," specify: "PVC tubing, 4.1 mm ID × 6.3 mm OD, 42 cm pump segment, Shore A 55, luer-lock connectors, PES H200 filter." A supplier can match that — they cannot match "the usual."

3. Confirm the Pump Segment Separately

Even if the rest of the tubing is correct, a mismatched pump segment degrades flow accuracy. Always call out the segment length, wall thickness, and durometer as separate line items.

4. Ask for Lot-Level Traceability

For regulated or auditable environments, request lot numbers and certificates of conformity with each shipment. This is standard for research-grade EBOO consumables and should be provided at no extra cost.

5. Order in Bulk When Possible

Multi-pack kits (like the 10-Pack Filters & Lines Complete Kit at $795) reduce per-unit cost and ensure you have a consistent supply of the same lot. Mixing lots mid-study can introduce subtle variability.

Replacement Tubing: When and Why

Replacement tubing is not just a convenience — it is a quality-control requirement. Over time, even unused tubing can degrade:

  • Plasticizer migration — PVC tubing slowly loses flexibility as plasticizers leach out, especially in warm or bright storage conditions.
  • Surface oxidation — Silicone and PVC surfaces can oxidize, changing their interaction with the circulating medium.
  • Compression set — Previously loaded pump segments may not return to their original dimensions, reducing occlusion and flow precision.

Best practice: treat every circuit as single-use. If your protocol allows limited reuse of the tubing (with a fresh filter), inspect the pump segment under magnification and replace the entire set if you see flattening, cracking, or discoloration.

Storage and Handling Tips

  • Store kits in original sealed packaging at 15–25 °C, away from direct sunlight.
  • Rotate inventory FIFO (first in, first out) to use oldest stock first.
  • Do not pre-open packaging; ambient humidity accelerates plasticizer loss.
  • Track shelf-life expiration dates and quarantine expired stock.

Frequently Asked Questions

What is the difference between an EBOO line set and a tubing kit?

The terms are often used interchangeably. An EBOO line set typically refers to the tubing circuit itself (arterial + venous runs plus pump segment). An EBOO tubing kit usually includes the line set plus the filter cartridge, connectors, and clamps — everything for a single run.

Can I use generic tubing instead of a manufacturer-specific kit?

Not recommended. Generic tubing may differ in ID, wall thickness, or material composition, which can affect pump accuracy and circuit integrity. Always match the device manufacturer's published specifications.

What are "ebo filters" or "ebbs filters"?

These are common misspellings of EBOO filters — the filtration membranes used in extracorporeal ozone research devices. The correct term is EBOO (Extracorporeal Blood Oxygenation and Ozonation). Similarly, "eboo lines" is shorthand for the tubing circuits described in this guide.

How do I know when to replace the pump segment?

Replace the pump segment (and ideally the full tubing set) after each use. If your SOP permits limited reuse, inspect for flattening, surface cracking, or permanent deformation. Any visible change means the segment should be discarded.

Where can I get help choosing the right kit?

If you are unsure which configuration fits your device, contact the EBOO Filters team with your device model and the spec checklist above. The team can confirm compatibility and recommend the right kit.
