The Yamato SQ-510C is the 200-240V configuration of Yamato's large-capacity top-loading steam sterilizer/autoclave (SQ510 model) in the non-drying SN/SQ series, with a 47.5 L effective chamber (nominal 50 L class). It is physically identical to the 100-120V SQ-500C (same wide-bore 47.5 L chamber, same PID microcomputer control, same safety suite) differing only in its 200-240V AC electrical build for higher-voltage mains.
The SQ series uses a wide-bore geometry (370 mm dia. × 442 mm depth), comparable volume to the SN500 in a shorter, wider cabinet (846 mm tall) that suits benches with limited overhead clearance and loads that are wide rather than tall. This is a non-drying autoclave (marketed "without dryer"), saturated-steam sterilization with post-cycle cooling, no forced-air drying stage.
Note: The catalog name lists "50L"; the Yamato SN/SQ spec table rates the SQ510 effective chamber capacity at 47.5 L (50 L is the nominal/marketing class). The catalog "220V" falls within the brochure's 200-240V rating. Brochure values are used here as authoritative.

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
- Large-batch instrument and glassware sterilization at 105-135°C. The wide 370 mm bore accommodates broad loads and the larger OMS-90 pail (dia 332 mm).
- Liquid and media sterilization. Dedicated liquid course plus agar-melt (65-100°C) and heat-retention (45-60°C) courses for media-prep at scale.
- 200-240V facilities needing a large-capacity wide-bore autoclave, the higher-voltage sibling to the SQ-500C, drawing just 10.5-12.5A.
Design Architecture
The SQ510 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. Its defining features are the wide-bore chamber (370 mm dia.) and the highest heater rating in the series, 1000W × 2.
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. The 200-240V build draws 10.5-12.5A, roughly half the current of the 100-120V SQ-500C at the same 1000W×2 heater rating.
Frequently Asked Questions
What is the effective chamber capacity of the SQ-510C? 47.5 L (50 L nominal class), in a wide-bore chamber measuring 370 mm diameter × 442 mm depth.
What voltage does the SQ-510C use? 200-240V AC, 50/60 Hz, drawing 10.5-12.5A. The 100-120V sister with the same 47.5 L chamber is the SQ-500C.
Does the SQ-510C dry loads after sterilization? No. It is a non-drying autoclave ("without dryer"), saturated-steam sterilization with post-cycle forced cooling, but no forced-air drying stage.
What cycles can it run? Six microcomputer-selectable courses: instrument sterilization, liquid sterilization, sterilization with keep-warm hold, agar-melt with keep-warm hold, agar-melt with heat retention, and manual operation.
What are its temperature and pressure ranges? Sterilization 105-135°C (melting 65-100°C, heat retention 45-60°C, preheating 45-80°C), with a maximum operating pressure of 0.255 MPa protected by a pressure safety valve.
Ordering & Configuration
Each SQ-510C ships with 2 racks, an OMS-90 pail (dia 332 × depth 195.5 mm), a steam cup, drain bottle, drain tray, filter, and instruction manual. Optional sample-temperature sensing is available.
As a capital instrument, the SQ-510C is quote-based. Contact Legacy Lab Supply for a formal quote. Confirm at quote: mains voltage and plug type (this is the 200-240V build; the 100-120V sister is SQ-500C), intended load profile, rack/basket needs, optional sample sensor, facility bench space for the 520 × 660 mm footprint, and lead time.
