Any impurity or exposure to contaminants—such as dust, microorganisms, or chemical interactions—can compromise the gel's acoustic properties and, by extension, the diagnostic outcome.

The Need for Purity in Ultrasound Gel Packaging

In medical diagnostics, even minor contamination of a coupling agent can:


  • Introduce imaging artifacts

  • Lead to false-positive or false-negative interpretations

  • Cause skin irritation or infection

  • Jeopardize cross-patient hygiene protocols


Traditional gel packaging methods (like bottles or open-top containers) often fail to protect gel from airborne or contact contaminants once opened. Moreover, repeated manual handling of rigid containers leads to issues such as:


  • Recontamination from hands or gloved surfaces

  • Spillage and air exposure

  • Difficulty maintaining sterility over time


This makes advanced packaging not just a convenience but a clinical requirement. Cubitainers are designed to address these hygiene and material integrity challenges.

What Is a Cubitainer?

Low-density polyethylene (LDPE) is used to make Cubitainers, which are semi-rigid, collapsible liquid containers. It is housed within a rigid outer corrugated box to provide structure during handling and transport.

Key characteristics include:

  • Collapsible design that contracts as contents are used

  • Airtight seal with tamper-evident caps and optional spouts

  • Chemical resistance to prevent interactions with gel contents

  • Easy dispensing with controlled flow through integrated nozzles

Cubitainers come in various sizes, typically ranging from 1 to 20 liters, making them suitable for both small clinics and large medical institutions.

How Cubitainers Preserve Gel Purity

A. Airtight Sealing Minimizes Air Exposure

One of the main routes through which gel gets contaminated is air contact. The collapsible nature of the Cubitainer ensures that as the gel is dispensed, air does not backfill the container—which is a common issue with rigid bottles. This limits the introduction of:

  • Dust particles

  • Bacteria and fungi

  • Moisture variations

By maintaining a closed system, Cubitainers preserve the gel's original consistency and sterility.

B. Sterile Manufacturing and Filling Conditions

Cubitainers are typically manufactured and filled under cleanroom or sterile conditions. Their simple yet secure design makes them ideal for:

  • Aseptic filling of ultrasound gel

  • Heat-sealing or tamper-proof capping, ensuring no external exposure until use

  • This makes them ideal for pharmaceutical-grade products like diagnostic gels.

C. Non-reactive LDPE Material

The LDPE used in Cubitainers is inert and resistant to chemical interactions with the gel. It doesn’t leach plasticizers, additives, or any volatile compounds that could affect gel formulation or purity. This chemical compatibility ensures:

  • No alteration in pH

  • No interference with ultrasound wave transmission

  • No breakdown of gel structure over time

User-Centric Benefits for Clinical Settings

Cubitainers offer more than just gel protection—they optimize clinical workflows and user safety.

A. Hands-Free Dispensing Options

Cubitainers can be connected to pumps or squeeze dispensers, enabling hygienic gel extraction without direct container contact. This is especially useful in:

Operating rooms

ICU environments

High-throughput imaging labs

B. Space-Saving and Efficient Storage

Their collapsible nature allows more units to be stored in a smaller footprint. Once empty, they can be flattened and disposed of easily, reducing waste volume.

C. Consistent Flow Rate

Thanks to built-in spouts and gravity-aided flow, Cubitainers ensure a steady, controlled dispensing rate, minimizing accidental spills and ensuring precision application.

Environmental and Cost Advantages

Aside from maintaining gel integrity, Cubitainers are environmentally friendly:

  • Reduced material use: Thinner walls than rigid plastic jugs mean less plastic consumption.

  • Easier disposal: Collapsible design makes waste management simpler.

  • Recyclable materials: LDPE is widely accepted in recycling streams.

Cost benefits include:

  • Lower shipping weight

  • Reduced damage risk during transport

  • Bulk filling capabilities, which reduce the per-unit packaging cost

These savings can be passed on to healthcare facilities without compromising product quality or safety.

Application Scenarios Where Cubitainers Shine

A. Large Medical Facilities

  • High-volume ultrasound departments benefit from Cubitainers due to:

  • Reduced gel waste

  • Long shelf life after opening

  • Lower unit cost over time

B. Mobile Imaging Units

Cubitainers are lightweight and durable, making them easy to transport without risk of breakage—ideal for mobile clinics and field hospitals.

C. Veterinary and Specialized Imaging Clinics

Clinics performing frequent scans on animals or delicate procedures (e.g., fetal, vascular, musculoskeletal ultrasound) need gel that maintains purity for optimal results. Cubitainers ensure uncompromised product quality throughout use.

Best Practices for Using Cubitainers in Medical Settings

To fully benefit from Cubitainer packaging:


  • Store in a cool, clean environment away from sunlight

  • Use with compatible dispensers or pumps to avoid external contact

  • Label with opening dates to monitor shelf life

  • Avoid using damaged or punctured Cubitainers

  • Train staff on proper handling and storage procedures


Following these practices can extend gel usability and prevent cross-contamination.

The Future of Gel Packaging: Smart and Safe

Cubitainers are already evolving with additional features such as:


  • Anti-bacterial inner linings

  • Built-in RFID tags for inventory tracking

  • Graduated scale markings for monitoring usage


As demand for sustainable, hygienic packaging rises, Cubitainers are expected to remain at the forefront of safe diagnostic consumable storage—especially as ultrasound use expands into telemedicine, remote diagnostics, and AI-assisted imaging systems.


In diagnostic ultrasound, gel purity ensures accuracy—not just cleanliness. Cubitainers provide a hygienic, cost-effective way to store and dispense gel while preserving quality.


Their sterile design minimizes contamination, extends shelf life, and boosts efficiency. For clinics prioritizing precision and safety, Cubitainers deliver reliable performance with meaningful clinical benefits.
