What Is Sepax Technology for Cord Blood Stem Cells?

Every parent wants to protect their child’s future. And in that quiet moment after birth, when the umbilical cord is clamped and cut, most people do not realize that it contains something more valuable than anyone talks about in delivery rooms. It holds cord blood stem cells, a biological resource that is increasingly being used to treat a range of serious medical conditions. But preserving those cells correctly is not as simple as just storing them. It requires precision, automation, and sterility. That is exactly where Sepax Technology steps in.

Let us break this down. What does Sepax do? Why does it matter? And what does it mean for a parent making decisions about stem cell preservation?

Understanding the Basics: What Is Sepax Technology?

Sepax Technology is an automated cell processing system that separates and concentrates cord blood stem cells from the rest of the collected material. At its core, it is a smart centrifuge, but one with far more precision, consistency, and sterility than any manual system could offer.

Sepax can collect up to 52% more cells than open methods. For example, instead of 600 million cells, it can collect about 912 million, enough to treat heavier patients. More than 2,500 cord blood units processed with Sepax have been used successfully in transplants, showing it is reliable for medical use.

Developed in Switzerland and used in stem cell banks across the globe, Sepax operates in a closed, sterile environment. That means from the moment the cord blood enters the machine to the moment the stem cells are isolated and stored, there is no open-air exposure. No pipetting by hand. No risk of contamination. No human error in deciding what to keep and what to discard.

It uses specific programming and sensors to analyze cell layers, identify the buffy coat (the thin layer where most stem cells are found), and isolate it efficiently. This ensures that the final preserved sample has the highest possible concentration of viable cells, the cells that will matter if that unit ever needs to be used in stem cell therapy.

Why Stem Cell Isolation Quality Matters?

Not all stem cell storage is equal. Two parents may both choose to bank their newborn’s cord blood, but the difference in processing could mean one child has a rich, ready-to-use sample while the other ends up with something far less effective.

The core reason this matters is simple: stem cells are not immortal. They are sensitive to their environment. Exposure to light, air, or incorrect temperature can compromise their structure. But even before storage, if the initial processing does not isolate enough viable cells or includes too much unwanted material, the therapeutic quality of the sample drops.

This is where Sepax Technology proves its worth. It delivers consistency across every single sample. No matter who collects the blood. No matter what time of day or where it happens. The system’s programming is standardized and precise. That gives parents the peace of mind that what is being stored is not just blood, but a potent source of stem cells that are clinically usable.

How Sepax Works: A Quick Look Inside the Process

The process starts after cord blood is collected post-delivery. It is transferred into a sterile, single-use processing kit designed for Sepax systems. The machine then follows a set of pre-calibrated steps:

Density gradient separation: Centrifugal force is used to separate the blood into layers based on weight.
Optical detection: Internal sensors detect the exact boundaries of the buffy coat.
Automated extraction: The stem cell-rich layer is extracted, avoiding contamination from red cells or plasma.
Concentration and volume reduction: The final sample is compact, potent, and optimized for cryopreservation.

Every step is logged digitally. That means no guesswork. No subjective judgment calls. Just scientifically repeatable output, every single time.

The Broader Context: Why Parents Are Choosing to Preserve Cord Blood

Today, stem cell therapy is not an abstract future promise. It is already being used in the treatment of over 80 diseases, including certain cancers, blood disorders like thalassemia, and immune deficiencies. Research is also expanding into the use of stem cell benefits for regenerative medicine, think spinal injuries, cerebral palsy, Type 1 diabetes, and even some forms of autism.

In all these applications, the quality of the stored sample matters. It determines transplant success. It influences whether a treatment can even proceed.

When a family banks their baby’s cord blood stem cells, they are not just storing genetic material. They are investing in a form of biological protection. That investment deserves the most advanced processing system available. That is why global stem cell banks: including Cryoviva, choose Sepax Technology as their platform.

Why Sepax Is the Gold Standard?

There are manual methods of processing stem cells. Some clinics still use them. They are cheaper. But they come with more variables — technician experience, time taken, sterility of the environment, and visual judgment of cell layers. That variability is exactly what you do not want when dealing with something as critical as your baby’s source of stem cells.

With Sepax Technology, those variables are removed. The system is closed. The outcome is logged. The concentration is higher. And the viability rates post-thaw are among the best in the industry.

In short, it is the difference between storing something and storing something useful.

Final Thoughts: Making an Informed Decision

Choosing to bank cord blood stem cells is a deeply personal choice. Some families do it because of a family history of genetic illness. Others do it simply to give their child more medical options in the future. Either way, if you are going to take that step, it makes sense to use a system that gives you the highest quality result.

Sepax Technology is not just a processing tool. It is a trust protocol. It is what makes the difference between a stored bag of cells and a future-ready therapeutic unit. And that is the kind of difference you want when the stakes are this high.

At Cryoviva, Precision Is a Promise

Cryoviva uses Sepax Technology in its cord blood processing workflow. That means every sample is handled with the same level of care, precision, and automation that global medical standards demand. If you are planning for delivery, now is the time to consider how to protect what that birth makes possible.
