Sterilizer With Dryer 32L Overview
The Sterilizer With Dryer 32L (model SM301) from Yamato Scientific is a fully automatic steam autoclave that carries samples from high-pressure sterilization through drying in one cycle. Sterilizing temperature spans 105 to 128°C and drying spans 150 to 180°C across a 32 L chamber. LabSupplies.com supplies this unit as an authorized dealer.
Key Features
- Automatic sterilize-to-dry cycle: high-pressure steam sterilization and a dedicated drying step run start to finish without operator intervention.
- Interactive key-input control: guided setup sequences the full cycle and lets drying temperature be set to sample material and quantity.
- Adjustable timer range: programmable from 1 to 999 hours for flexible cycle scheduling.
- Front-panel drain management: a level indicator confirms drain bottle water at a glance and a front-mounted drain valve gives easy access.
- Built-in safety systems: self-diagnostic functions speed error recovery and a condensation collector neutralizes high-temperature exhaust steam.
How to Choose the Right Sterilizer / Autoclave
Matching an autoclave to a lab means weighing chamber size, achievable temperatures, control style, and site power. Use the criteria below to confirm fit.
- Capacity: chamber volume determines how many baskets or flasks process per cycle; size it to peak daily throughput rather than average load.
- Temperature range: verify the sterilizing band covers your protocol and that a drying stage is included if loads must be ready immediately.
- Voltage: confirm whether your facility supplies 115V or 220V so the ordered model matches the available circuit.
- Footprint and weight: check bench or floor clearance and load-bearing capacity against the unit dimensions and shipping weight.
- Safety features: self-diagnostics and exhaust-steam neutralization protect operators and ease maintenance.
