Reusable, heat-sensitive instruments such as flexible endoscopes, anaesthetic circuits, and ophthalmic tools require meticulous reprocessing to ensure patient safety and maintain device integrity. Choosing an appropriate disinfectant is not only a matter of efficacy but also of compatibility, workflow efficiency, and compliance with strict regulatory standards.
The challenge of reprocessing complex devices
Complex geometries, narrow lumens, and delicate materials make certain medical devices difficult to disinfect thoroughly. When heat sterilisation is not possible, high-level disinfection (HLD) provides a validated, practical alternative. The right chemistry must deliver a broad antimicrobial spectrum while avoiding damage to sensitive materials like plastics, adhesives, and elastomers.
In these cases, a carefully formulated solution such as https://www.arxada.com/en/hygiene/hygiene-emea/nugen-hld-cd can support consistent, high-level disinfection with proven compatibility data and workflow flexibility. Its role is to balance performance with safety, ensuring reliable results even in high-throughput reprocessing departments.
What to consider when selecting a disinfectant
When evaluating options for medical device disinfection, several key factors guide the selection process:
- Efficacy spectrum: Verify proven activity against bacteria, fungi, viruses, and mycobacteria under realistic conditions.
- Material compatibility: Ensure the formula does not cause corrosion, clouding, or brittleness over repeated cycles.
- Contact time and temperature: Short, room-temperature cycles can reduce bottlenecks without compromising efficacy.
- Residue and rinsing: Low-residue products are easier to rinse, minimising the risk of device malfunction.
- User safety: Low-odour, low-irritation formulations improve safety for staff during manual or automated processing.
A systematic evaluation process – combining laboratory validation and field testing – helps ensure that the chosen disinfectant performs consistently within the facility’s reprocessing framework.
Ensuring compliance and documentation
Under the EU Biocidal Products Regulation (BPR) and the Medical Device Regulation (MDR), disinfectants must demonstrate verified safety and efficacy. Manufacturers must supply compatibility data, test results, and clear instructions for use. For hospitals and clinics, this documentation supports traceability, risk assessments, and audits.

Towards sustainable and efficient reprocessing
Sustainability and operational efficiency increasingly shape disinfectant selection. Ready-to-use formulations reduce dilution errors, while lower-toxicity and biodegradable ingredients support environmental goals. At the same time, improved material compatibility extends instrument lifespan, contributing to long-term cost and waste reduction.
Selecting the right disinfectant is about more than achieving microbiological targets; it is about building a reprocessing system that is safe, efficient, and sustainable. Facilities that combine robust chemistry, validated procedures, and trained personnel can achieve consistent, high-quality results across every cycle of device reprocessing.
