Applications
Vacuum ovens like the National Appliance 5840 are standard equipment in research laboratories, university chemistry and materials science departments, and light industrial settings. They are used for drying moisture-sensitive or heat-sensitive materials at reduced pressure, degassing adhesives, resins, and potting compounds, curing coatings under controlled atmosphere, and removing solvents from samples without exceeding their degradation temperature. Because the vacuum lowers the boiling point of water and solvents, these ovens can dry materials gently at much lower temperatures than a standard convection oven. They are also used in electronics manufacturing and failure analysis for drying components and assemblies, and in pharmaceutical and food science labs for drying granulates and powders.
This National Appliance Co 5840 lab vacuum oven powers up and responds to manual controls. It is being sold as-is with no warranty. The unit is in used condition with paint wear and surface scuffs consistent with lab use; the blue exterior shows some aging but the chamber interior and door gasket appear intact. No manual or peripherals are included — the oven ships as shown. Please view our photo set and contact us if you have any questions.
