SED-250ZKX-S is a 25 L tabletop vacuum drying oven with a 304 SS inner chamber (300×300×275 mm, 3 mm thick) and a Baosteel cold-rolled, electrostatic-spray-coated outer shell. External dimensions 610×470×470 mm, net weig
مبدأ العمل
Samples are placed in a sealed 304 SS chamber and the chamber is evacuated by a separately purchased pump to ≤100 Pa. Reduced pressure dramatically lowers the boiling point of solvents, allowing low-temperature drying of heat-sensitive materials without oxidation or air-flow disturbance. A proprietary sleeve-type heating element wrapped around the chamber transfers heat uniformly through conduction and natural convection while moisture vapor is continuously pumped out. The PID controller with embedded temperature sensor maintains ≤±0.3°C fluctuation. Auto parameter save-on-power-interruption and power-recovery resume prevent data loss.
