Front view of a WIST Vacuum Oven with large tempered glass door and clear view of the stainless steel interior chamber, ideal for solvent removal and low-temperature drying.

Vacuum Oven (Max 250°C)

The WIST Vacuum Oven is designed for controlled drying, heating, and thermal processing under reduced pressure in laboratory and industrial environments. Operating up to 250°C with vacuum capability, it features stainless steel interiors, precise PID control, and vacuum-tight construction, ideal for heat-sensitive drying, solvent removal, and advanced material testing.

Key Features:

Temperature range: Ambient +5°C to 250°C
Vacuum range: 1 mbar to atmospheric pressure
PID microprocessor-based temperature and vacuum control system
Double-walled construction with vacuum insulation for thermal efficiency
Inner chamber made of stainless steel 304 grade
Exterior made of powder-coated mild steel (CRCA)
