Laboratory Furnaces

Laboratory furnaces have versatile applications:

• Ash determination and incineration: Removing organic matter from samples at high temperature
• Heat treatment applications: Heating materials to alter their structural properties
• Drying and baking processes: Pre-treatment of ceramic, glass, and metal samples
• Material testing: Melting point, thermal resistance, and expansion measurements
• Preparation before chemical analysis: Processing samples at high temperature for analysis readiness
• Electronics and metal industries: Soldering, annealing, tempering processes
