How to Compare Sterile Processing Equipment

Start with what must be processed

Export a representative month of trays and devices. Group them by heat sensitivity, material, lumen dimensions, packaging, weight, and IFU-specified processing route. A sterilizer or washer is only a candidate if it can process the actual device models in your inventory under the required conditions.

Measure the whole cycle

Advertised cycle time is one component of turnaround. Add pre-cleaning, manual steps, loading, monitoring, drying, unloading, cooling, release, and transport. For a washer, include rack setup and inspection after the load. For a sterilizer, include the department’s biological-indicator policy and documentation. Model the peak hour, not just an average day.

Put capacity in a room diagram

Trace cart paths, clean and dirty separation, staging, doors, staff positions, maintenance clearance, utilities, and potential expansion. A chamber with strong published capacity can underperform if the room makes loading slow or creates a clean-side queue. Ask facilities engineering and SPD leadership to sign off on one shared layout.

Compare five-year operating cost

Include installation, utilities, chemistry or sterilant, monitoring consumables, racks, service contract, planned maintenance, downtime coverage, and staff time. Ask for the cost assumptions in writing and use your actual load mix to challenge them. The lowest purchase quote can be the expensive choice if it needs more cycles or causes more handling.
