The Yamato ADP-300C is a 27 L benchtop programmable vacuum drying oven, the larger member of the Yamato ADP200/300 pair (27 L vs 10 L). It dries heat-sensitive materials gently by decompression radiation heating: reducing chamber pressure lowers the boiling point of moisture and solvents so they evaporate well below their atmospheric boiling points., the 27 L chamber suits multi-sample vacuum drying, moderate-batch solvent removal, and shared-bench moisture-sensitive preparation where the 10 L ADP-200C would run out of shelf area.
Its 220V sister is ADP-310C (same 27 L chassis); step down to ADP-200C / ADP-210C for the compact 10 L chamber.

Voltage note: The ADP200/300 operation manual documents the 100V-base chassis (100V AC, 12A). The ADP-300C is the 115V programmable variant; the 1.05 kW mica-heater rating is carried from the manual. The 220V sibling is ADP-310C.
Application Profile
Moderate-batch solvent removal. Vacuum drying pulls residual solvents out of powders, films, and reaction products at low temperature, avoiding thermal degradation. The 27 L chamber holds more and larger vessels than the 10 L model per cycle.
Moisture-sensitive sample preparation. Reduced-pressure drying removes bound and surface moisture from hygroscopic reagents, electronic components, and materials samples before weighing, coating, or further processing, without oxidative exposure.
Heat-sensitive material drying. Solvents flash off at reduced pressure well below their atmospheric boiling points, so degradation-prone organics, biologics, and polymers dry gently. The ±10 °C distribution and ±1.5 °C control accuracy (at 240 °C, no load) support repeatable results across three shelf levels.
Degassing and outgassing. Reduced-pressure operation drives dissolved gases and volatiles out of resins, adhesives, and cast materials prior to curing or measurement.
Shared-bench and multi-user drying. The 27 L capacity and three shelf levels suit a shared bench where several users' samples run concurrently.
Design Architecture
The ADP-300C dries by decompression radiation heating: a 1.05 kW mica heater warms the SUS304 stainless chamber while an external vacuum pump (connected via the 18 mm-OD intake port) evacuates it to as low as 0.1 kPa (~1 Torr). Lowering pressure suppresses the boiling point of water and solvents, so evaporation proceeds at low temperature and heat-sensitive samples are not thermally stressed.
Control. A digital PID microcomputer controller (VS1) governs setpoint temperature across the 40–240 °C range with ±1.5 °C adjustment accuracy at 240 °C. Digital temperature setting and display, plus a timer with auto-start / auto-stop selection, support the programmable operation the -C designation denotes. Vacuum is read on a Bourdon-tube gauge and managed manually via the pump and purge valves.
Chamber and viewing. The 300 × 300 × 300 mm interior holds three aluminum shelves (pitch 71 mm, ~15 kg each). A 12 mm reinforced-glass inspection window with a polycarbonate protection plate allows samples to be observed under vacuum.
Safety. An over-current earth-leakage breaker plus a dual (independent) overheating-prevention circuit protect the load; the temperature-measurement circuit, CPU, sensors, and output stage are independent of the overheat circuit. Never operate this oven with flammable or explosive materials or in a flammable/explosive gas atmosphere. The unit is not explosion-proof.
Frequently Asked Questions
What is the ADP-300C's chamber capacity? 27 L, the larger member of the ADP200/300 pair (27 L vs 10 L).
How does it dry samples? By decompression radiation heating: a 1.05 kW mica heater warms the SUS304 chamber while an external pump evacuates it to as low as 0.1 kPa (~1 Torr), so moisture and solvents flash off gently below their atmospheric boiling points.
What temperature range and accuracy does it offer? 40 to 240 °C, controlled to ±1.5 °C at 240 °C, with a ±10 °C distribution across three aluminum shelves.
Does it include a vacuum pump? No. It requires an external pump (~50 L/min) connected to the 18 mm-OD intake port with a vacuum hose. Confirm pump and hose kit at quote.
What voltage is the ADP-300C? The 115V configuration; the ADP-310C is the 220V sibling on the same 27 L chassis.
Ordering & Configuration
Included: 3 aluminum punched-metal shelves and power cord (per the ADP200/300 manual accessory list).
Pair with a vacuum pump. The oven requires an external vacuum pump (approx. 50 L/min displacement) connected to the 18 mm-OD intake with a vacuum hose. Confirm pump and hose kit selection at quote.
Confirm voltage and plug. The ADP-300C is the 115V configuration; the ADP-310C is the 220V sibling on the same 27 L chassis. Confirm supply voltage and receptacle at order.
Confirm application fit. Verify sample chemistry, target drying temperature and vacuum level, batch size versus the 27 L chamber, and whether the compact 10 L ADP-200C/210C is a better match.
Request a quote for pricing, vacuum-pump pairing, voltage/plug configuration, lead time, and warranty terms. Warranty per Yamato standard capital-equipment terms. Confirm at quote.
