Description

A hot air oven is a laboratory and industrial device used for dry heat sterilization, drying, baking, or heat treatment of materials. It uses dry, circulating hot air and is commonly found in microbiology, pharmaceutical, and electronics labs. Here are the main features:

Features of a Hot Air Oven

Temperature Range
Typically ranges from 50°C to 250°C (some models go up to 300°C).
Thermostatic/ Digital Control
Equipped with analog or digital temperature controllers for precise heat regulation.

Forced Air Circulation
Uses a fan/blower to circulate hot air for uniform heating.
Ensures consistent temperature throughout the chamber.
Double-Walled Insulated Construction
Inner chamber usually made of stainless steel.
Outer body made of mild steel or powder-coated metal.
Insulation (usually glass wool) minimizes heat loss.

Safety Features
Over-temperature protection (alarm or auto shut-off).
Door lock to prevent accidental opening during operation.
Indicator lights for heating and power status.
Adjustable Shelves
Multiple removable shelves for flexible sample placement.

Timer Function
Programmable timers to automate heating cycles.
Glass Window or Door (Optional)
Allows visual monitoring without opening the oven and losing heat.
Compact and Sturdy Design
Benchtop or floor-standing models depending on capacity.

Energy Efficient Operation
Designed to retain heat and consume minimal electricity during operation.

Common Applications<
Sterilizing glassware and instruments
Removing moisture from samples
Heat treating materials in electronics and metallurgy
Baking powders, resins, and chemicals
Sample drying in microbiology and pharmaceuticals
