A new approach to verifying filter performance
This is where Bürkert’ s MS02 Chlorine Cube sensor offers a new solution. Originally developed for demanding pharmaceutical and drinking water applications, the MS02 has proven particularly well suited to monitoring GAC filters in dialysis water treatment systems.
The MS02 uses an innovative amperometric-on-chip design protected by an immobilised membrane, eliminating the need for electrolyte buffers. This allows it to achieve a T90 response time of around 30 seconds, dramatically faster than conventional technologies. For dialysis applications, that speed means faster alarms, quicker intervention and reduced risk to patients.
Crucially, the MS02 is sensitive enough for zero-chlorine measurement, making it ideal for monitoring the outlet of carbon filters. Its stable floating zero point avoids polarisation effects and removes the need for artificial chlorine dosing, simplifying system design and validation. With no reagents and minimal maintenance requirements, the sensor supports long service intervals – users have

reported continuous operation for over two years without recalibration.
Bürkert’ s wider role in dialysis technology
Chlorine monitoring is only one part of the dialysis process, and Bürkert’ s involvement goes far beyond sensing. The company works closely with dialysis machine manufacturers through its global network of Systemhaus locations, supporting projects from concept development through to full-scale production.
A notable example is Bürkert’ s collaboration with a leading manufacturer on its latest dialysis machine. By developing a compact, integrated fluidic assembly incorporating valves, sensors and pumps, Bürkert helped simplify setup, reduce error risk and improve workflow efficiency for clinical staff. All components are designed to meet stringent medical standards for hygiene, durability and biocompatibility, while also supporting quieter operation for home and nocturnal dialysis environments.
This systems-level expertise is increasingly important as dialysis treatment evolves. With more patients opting for home haemodialysis or overnight therapies, manufacturers face growing demands for compact, reliable and user-friendly equipment that does not compromise on safety.
Recognition for innovation
The significance of Bürkert’ s advances in chlorine measurement has recently been recognised by the industry. The MS02 Chlorine Cube sensor was recently awarded Highly Commended – Sensor Product of the Year by a leading industry magazine, underlining its impact in high-criticality applications such as healthcare and water treatment.
Safeguarding patients
As the global incidence of chronic kidney disease continues to rise, the pressure on dialysis infrastructure will only increase. Ensuring that every litre of water used in treatment is free from harmful chlorine is a nonnegotiable requirement.

By combining proven carbon filtration with fast, accurate and low-maintenance chlorine sensing, dialysis users can significantly reduce risk while improving operational confidence. Bürkert’ s MS02 sensor, alongside its broader expertise in fluid control and medical system integration, demonstrates how innovative engineering can translate directly into safer outcomes for patients and greater assurance for clinicians and operators alike.
