Hot Air Oven – Accurate Temperature Control for Labs

A hot air oven is an electrical device that uses dry heat sterilization to sterilize laboratory glassware, powders, metal instruments, and other heat-resistant materials. 

Unlike autoclaves, hot air ovens don’t rely on steam; instead, they use a well-insulated chamber and a controlled thermostat for precise temperature regulation. This method minimizes the risk of corrosion, pressure build-up, and damage to sensitive lab parts. 

Wide Temperature Range (50–250 °C)
The Hema hot air oven supports temperatures as low as 50 °C, scaling up to 250 °C — perfect for applications ranging from gentle drying to rigorous sterilization.

High Temperature Accuracy
Thanks to a microprocessor-based PID digital temperature controller and PT-100 sensor, you can expect ± 1 °C accuracy in many models.

Uniform Heat Distribution
Forced air circulation (fan-based) ensures consistent temperature throughout the chamber. Uniform heating eliminates hot spots, which is critical for reliable results.

Robust Construction & Insulation

  • Double-walled or triple-walled construction (depending on model) for better insulation.

  • Inner chamber in stainless steel (or mild steel, depending on model) for durability.

  • High-grade glass wool between walls ensures minimal heat loss and energy efficiency. 

 Safety Features
  • Safety thermostat for protection against overheating.

  • Air vents for gas or fumes to maintain a safe operating environment.

  • Secure locking door with strong hinges and insulation to keep the heat in.

Digital Controller & Timer
Many models include digital temperature controllers with auto-tune PID algorithms, dual display (set value vs process value), and timer functions to automate sterilization or drying cycles.

Custom & GMP-Compliant Models
Hema Scientific Instruments offers a range of hot air ovens — from lab-type to GMP (Good Manufacturing Practice) ovens, tailored to pharmaceutical and biotech industries.

The Hema Hot Air Oven is a versatile instrument used across a variety of lab, industrial, and pharmaceutical settings:

  • Sterilization: Glassware, pipettes, powders, metal tools — especially where moisture-based sterilization (autoclaving) is not preferred.

  • Drying: Removing moisture from samples, reagents, or components before further testing.

  • Aging Tests / Thermal Stability: Testing materials or products under prolonged high-temperature exposure.

  • Quality Control: In pharmaceutical manufacturing, to ensure parts or drugs are free from microbial contamination.

  • Research Applications: For universities, research labs, and biotech companies working on experiments that demand precise thermal control.
