Yamato ADP-200C Vacuum Drying Oven, 0.35 Cubic Foot (10 liter), Max Temp 240 °C, Down to 0.75 Torr 115 VAC

The Yamato ADP-21 legacy vacuum ovens were very popular in the vacuum community but are now being replaced with the NEW Yamato ADP 200C. The ADP-200C is now the direct replacement for the older ADP-21 vacuum ovens. We would like to give a few brief comparisons between the New Yamato ADP-200C and the now discontinued Legacy ADP-21 models.

The new ADP200C offers the following differences from the ADP-21:

• CE Mark for Sale in European countries
• Operating Temperature Range of +20 °C to 240 °C, instead of +5 °C to 240 °C
• Programmable Features with the new VS4 controller
• Digital Readout on Control Panel
• Larger Vacuum and Purge ports, 18mm

The Yamato ADP-200C operates in the temperature range from room temperature plus +20 °C to 240 °C (up to 465° F) and in the vacuum range from atmosphere to 0.75 Torr. This vacuum oven is the smallest oven in this series and is built on a compact design, having an internal volume of 0.35 cubic foot (10 liters). The interior vacuum vessel is made of 304 stainless steel and contains aluminum removable shelving. The vacuum door has a large observation window made of 12mm thick tempered glass with a vacuum seal made of silicon. These vacuum ovens have good temperature stability and an accuracy of +/- 1.5 degrees C at 150 C and can reach its maximum operating temperature within 70 minutes. The vacuum and vent valves are located on top of the oven and have a 18 mm hose barb for vacuum hose connections. The Yamato ADP-200C has a small footprint (16.81x17.6x21.06 inch) and requires 115 VAC at 50/60 Hz and 7 Amps. Offered separately on our website is the Yamato ADP-210C, which has all the same specifications as the ADP-200C but requires 220 VAC 50/60 Hz and 4 Amps to operate. The complete specifications and operator instruction manual in PDF format can be downloaded below (see available downloads).

Need the ultimate in quiet operating vacuum pump equipment? Check out our Varian frequency controlled oil-sealed rotary vane and dry scroll vacuum pumps. When the oven reaches vacuum the pumps slow down and operates extremely quiet. This save electrical power (observed as low as 180 Watts where a normal fixed frequency pump uses 800 Watts) and allows the laboratory to be library quite for study and research. Added benefits are, frequency controlled pumps run cooler and contribute less heat into the laboratory and require less service because slower rotational speeds do not produce as much mechanical wear on the pump parts. We offer the Varian TriScroll 300 and 600 Inverter dry scroll and Varian HS452 and HS652 oil sealed rotary vane pumps which are sold on this website. (Please see our Related section below to find more information on these vacuum pumps.)
