Vacuum Oven

                         Vacuum Oven Specifications

1. Chamber Size / Volume

• Internal workspace where samples are placed.

• Typical range: from ~10 L (small lab) to 1000 L+ (large industrial). 

2. Temperature Range

• Indicates the lowest to highest temperature it can reliably reach.

• Typical lab ovens: Ambient +5 C up to ~200 C250 C. 

• High-temperature specialist units can go above this depending on application. 

3. Temperature Accuracy & Stability

• How close the internal temp stays to set value.

  • Typical stability: 1 C to 2 C. 

• Resolution of digital controller often 0.1 C. 

4. Vacuum Level / Pressure

• Measured usually in Pa, mmHg, or mbar.

• Standard levels:

  • ~133 Pa or better (low pressure to remove moisture/oxidation). 

  • Up to 760 mmHg (near full vacuum) on precision models. 

5. Materials & Construction

• Inner chamber: Stainless steel (SS304 or SS316) to resist corrosion. 

• Exterior: Powder-coated steel for durability. 

• Insulation: Glass wool or mineral wool to help maintain temperatures. 

6. Controls & Display

• Digital PID controllers are common for precise temperature & timing. 

• Features may include timers, alarms, data logging, and PC interfaces. 

7. Shelving

• Adjustable stainless steel trays; typical units have 23 shelves. 

8. Power Requirements

• Usually 220240 V AC, 50/60 Hz for lab models.
