The Despatch LAC1-38A-5 is a benchtop electric oven delivering precise thermal control across 40°C to 260°C (104°F to 500°F) for laboratory and light industrial heating applications. Horizontal recirculating airflow with high-volume fan and perforated stainless steel walls maintains ±1°C uniformity at 100°C and ±0.5°C stability. The 3.7 cu ft (105 L) chamber reaches 260°C in 40 minutes with 7-minute recovery after door opening, supported by three inches of fiberglass insulation and type 304 stainless steel construction.
