If your practice reprocesses reusable instruments, a tabletop steam autoclave is essential. Picking the right one depends on what you sterilize, how much and how quickly you need it back.
This guide covers cycle types, sizing and the supplies that go with sterilization.
Cycle types
- Class N cycles are for solid, unwrapped instruments.
- Class B cycles use vacuum stages to remove air, allowing sterilization of wrapped and hollow instruments. Most clinics that pouch their instruments choose a Class B unit.
- Class S cycles are defined by the manufacturer for specified loads.
Sizing and throughput
Look at chamber size, cycle time including drying, and how many trays fit per load. Consider your busiest day: if instruments must be turned around between appointments, a faster cycle or a second unit may be worth it.
Supplies you'll need
- Sterilization pouches or wraps sized to your instruments
- Chemical indicators (internal and external)
- Biological indicators (spore tests); CDC guidance calls for spore testing at least weekly
- Distilled water, if your unit requires it
- A logbook or digital record for each cycle
Maintenance
Follow the manufacturer's cleaning schedule for the chamber, door gasket and filters. Plan for periodic service and calibration, and keep a backup plan, such as extra instrument sets or disposables, in case the unit is down.
A simple sterilization workflow
- Clean instruments first: sterilization doesn't replace cleaning.
- Inspect, dry and package them in pouches sized correctly, with a chemical indicator inside.
- Load without overcrowding, so steam can circulate.
- Run the right cycle, then let packs dry completely before handling.
- Record each cycle and store packs in a clean, dry place.
Common mistakes
- Overloading the chamber, which leaves wet packs or incomplete sterilization.
- Using pouches that are too small, so the seal is stressed.
- Skipping routine spore tests.
- Using tap water when the manufacturer requires distilled.
Frequently asked questions
Do I need a Class B autoclave?
If you sterilize wrapped or hollow instruments, most practices choose Class B. Class N suits only solid, unwrapped items.
How often should we run spore tests?
CDC guidance for healthcare settings recommends biological monitoring at least weekly, and with every load that contains an implant. Follow your own protocols as well.
Do you supply pouches and indicators?
Yes. We can quote the autoclave with pouches, chemical and biological indicators, and set them up as a standing order.
Can we sterilize single-use items?
No. Single-use devices are labeled for one use and shouldn't be reprocessed.
