The Yamato SDP-610 is a 264 L floor-type programmable vacuum drying oven — the largest and deepest-vacuum model of the USA-built SDP series. A fully programmable EZ-ZONE Watlow controller and cool-touch surface pair with a digital vacuum gauge reading in Torr and mTorr (display range 760 Torr down to 0 mTorr), and a Viton gasket combines high-temperature performance with chemical resistance. on a 230V supply, it is the right pick for high-vacuum production drying, large-load solvent removal, and demanding degassing where the smaller SDP benchtop models cannot reach the capacity or vacuum depth required.
Step down to SDP-400/410 (127.4 L) or SDP-300/310 (47.2 L) for smaller loads.

Application Profile
High-vacuum production drying. The SDP-610's digital gauge reads down to 0 mTorr with a maximum permitted end vacuum of 10 mTorr and a 30 mTorr / 30 min leak rate — a deeper, more tightly specified vacuum envelope than the smaller SDP models — for demanding low-pressure drying of heat-sensitive materials at production scale.
Large-load solvent removal. The 264 L chamber holds substantial batches of powders, films, and reaction products; reduced pressure lowers solvent boiling points so residual solvents are stripped gently on programmable ramp-and-soak profiles.
Demanding degassing and outgassing. Deep vacuum drives dissolved gases and volatiles out of resins, adhesives, and cast materials before curing or measurement — the Viton gasket withstands aggressive-solvent and high-temperature exposure.
Moisture-sensitive preparation at production scale. Bound and surface moisture is removed from hygroscopic reagents and materials before weighing, coating, or analysis, without oxidative exposure.
Facility / shared production use. The floor-standing 264 L capacity and cool-touch surface suit a shared production or scale-up environment running large loads.
Design Architecture
The SDP-610 evacuates a 300-series stainless chamber (264 L) through a KF25 access port; a digital gauge displays vacuum from 760 Torr down to 0 mTorr, with a 10 mTorr maximum permitted end vacuum and a 30 mTorr-in-30-min leak rate. An EZ-ZONE Watlow controller governs temperature from RT +15 °C to 220 °C at 0.1 °C display resolution, with ±6.0 % of setpoint midrange uniformity and stability of ±0.2 °C at 80 °C and 150 °C. Programmable ramp-and-soak profiles run multi-step methods automatically.
Door, seal, and safety. A positive-latch handle with spring-loaded glass maintains the vacuum seal; the standard chamber gasket is Viton, chosen for combined high-temperature and chemical resistance. A secondary independent high-limit controller provides over-temperature safety protection, and the exterior is a cool-touch surface.
Thermal performance. From a 25 °C room the chamber reaches 80 °C in ~80 min, 150 °C in ~130 min, and 220 °C in ~180 min.
Chamber and shelving. The 710 × 609 × 609 mm interior offers 3 shelf-rest steps; each 287 × 483 mm shelf carries up to 34 kg, with a 102 kg maximum total load.
Safety. Built-in over-temperature protection and TUV-compliant construction. Never use in a flammable or explosive gas atmosphere, and never process explosive or flammable material. High-temperature components — observe burn-hazard cautions.
Frequently Asked Questions
What is the SDP-610's chamber capacity? 264 L — the largest model in the USA-built SDP vacuum-oven series.
What temperature and vacuum range does it reach? RT +15 °C to 220 °C, with a digital gauge reading from 760 Torr down to 0 mTorr, a 10 mTorr maximum permitted end vacuum, and a 30 mTorr / 30 min leak rate.
What controller does the SDP-610 use? A fully programmable EZ-ZONE Watlow controller at 0.1 °C display resolution, running multi-step ramp-and-soak profiles.
Why a Viton gasket instead of silicone? Viton is standard on the SDP-610 for combined high-temperature and chemical resistance against aggressive solvents — a difference from the silicone-gasketed smaller SDP models.
Does the SDP-610 include a vacuum pump? No. It connects via KF25 to an external pump; Yamato lists matched kits (e.g. the GLD202 oil pump or NEODRY15G2 dry-pump kit) — confirm pump selection at quote.
What electrical supply does it need? AC230V, 20A, 50/60 Hz, with no plug (round terminal) — plan a hardwired connection.
Ordering & Configuration

Pair with a vacuum pump. The SDP-610 connects via KF25 to an external pump; Yamato lists matched kits including the GLD202 oil vacuum pump with rubber- or SUS-hose kit (220V) and the NEODRY15G2 dry-vacuum-pump kit. Confirm pump selection for the target end vacuum at quote.
Confirm electrical supply. The SDP-610 is AC230V, 20A, with no plug (round terminal) — plan a hardwired connection. Confirm supply and circuit at order.
Plan floor space and installation. At 965 × 1189 × 1624 mm external and ~223 kg, this is a floor-standing unit — confirm doorway/room access, floor loading, and service clearance at order.
Confirm application fit. Verify sample chemistry, target temperature/vacuum (including whether the 10 mTorr end vacuum is required), batch size versus 264 L, and whether a smaller SDP model would suffice.
Request a quote for pricing, vacuum-pump pairing, electrical/installation planning, lead time, and warranty. Warranty per Yamato standard capital-equipment terms — confirm at quote.
