Precision Laboratory Thermal Processing
TEMPO Instruments Laboratory Hot Air Ovens are engineered for high-accuracy thermal drying, sterilization, and depyrogenation adhering strictly to pharmacopeial and laboratory quality standards (WHO-GMP & ISO 9001:2015).
Standard Dry Heat Sterilization Parameters
Primary Laboratory Applications
- • Pharmaceutical & Biotech: Depyrogenation & glassware sterilization
- • Chemical Analysis: Moisture content determination & sample drying
- • Materials & Polymers: Thermal aging, annealing & resin curing
- • Clinical & Microbiological: Dry heat tool decontamination
Triple-Walled Construction & Heating Architecture
Constructed with triple-walled modular casing insulated with high-purity resin-bonded glass wool insulation. Heat is generated by 80/20 Nichrome wire tubular elements positioned along the air plenum for uniform thermal absorption and minimal heat radiation to external surroundings.
