The Yamato SN-310C is the 200-240V configuration of Yamato's 32 L top-loading steam sterilizer/autoclave (SN310 model) in the non-drying SN/SQ series. It is physically identical to the 100-120V SN-300C (same 32 L chamber, same PID microcomputer control, same safety suite) differing only in its 200-240V AC electrical build for labs and regions standing on higher-voltage mains.
This is a non-drying autoclave (marketed "without dryer"), saturated-steam sterilization with post-cycle cooling, no forced-air drying stage. It sits between the 20 L SN200 class and the 47 L SN500 class, giving a practical mid-capacity chamber.

Cycle Types / Operation Courses
Six microcomputer-selectable operation courses (per the series spec table): instrument sterilization, liquid sterilization, sterilization with keep-warm hold, agar-melt with keep-warm hold, agar-melt with heat retention, and manual operation. Setpoints are entered digitally via UP/DOWN keys under microcomputer PID control.
Application Profile
- Instrument and glassware sterilization at 105-135°C for microbiology, cell culture, and clinical labs.
- Liquid and media sterilization. Dedicated liquid course, plus agar-melt (65-100°C) and heat-retention (45-60°C) courses for media prep that melts agar and holds it pourable.
- 200-240V facilities that require a mid-capacity 32 L autoclave. This is the higher-voltage sibling to the SN-300C.
Design Architecture
The SN310 uses a manual up/down lid mechanism with attached safety interlock and a small-size pressure vessel design. Temperature is governed by microcomputer PID control with digital UP/DOWN setpoint entry and digital display.
The standard safety-device suite covers sensor-failure detection, SSR short-circuit detection, disconnected-heater detection, water-level detection (liquid-expansion method), drain-bottle configuration-error warning, lid-lock error detection, memory-error detection, and a 0.255 MPa pressure safety valve. An exhaust valve provides full-open and slow-exhaust modes; an axial fan motor drives forced cooling. Option ports accept a sample sensor (1/4), recorder (1/4), and pressure-indicator connection. A 3 m power cord exits the unit. The 200-240V electrical build draws 8.5-10A, roughly half the current of the 100-120V SN-300C at the same 800W×2 heater rating.
Frequently Asked Questions
What is the chamber capacity of the SN-310C? The SN-310C has a 32 L effective chamber (300 mm dia. × 445 mm depth), positioning it between the 20 L SN200 class and the 47 L SN500 class.
Is the SN-310C a 100-120V or 200-240V unit? The SN-310C is the 200-240V AC configuration (50/60Hz, 8.5-10A). Its physically identical 100-120V sister is the SN-300C; confirm mains voltage and plug type at order.
Does the SN-310C have a drying stage? No. The SN-310C is a non-drying autoclave ("without dryer"). It runs saturated-steam sterilization with post-cycle cooling, but no forced-air drying stage.
What temperatures and cycles does the SN-310C run? It sterilizes at 105-135°C and offers six microcomputer-selectable operation courses, including instrument sterilization, liquid sterilization, agar-melt (65-100°C), and heat-retention (45-60°C) courses under PID control.
