Despatch Laboratory Ovens LAC 1 38a 6

Despatch Industries LAC 1 38a 6 Laboratory Convection Oven is a heavy duty benchtop oven. It’s a top choice among despatch laboratory ovens. This oven is versatile, capable of handling both simple tasks like drying glassware and more intricate processes referred to as complex heating applications. Constant horizontal airflow means uniform heating across all shelves, shorter cycle times and controlled ramp rates. Stainless interior and better thermal uniformity for curing, drying, sterilizing and aging. Glass insulation and double wall construction for energy efficiency and heat loss minimization.

Stainless Steel Interior & Thermal Performance

The Despatch LAC 1-38A-6 laboratory convection oven features a stainless steel interior that is durable, easy to clean, and ideal for maintaining a sterile laboratory environment. It is designed for process-critical applications that demand consistent and accurate temperature control, including curing, drying, sterilizing, and thermal evaluation.

With double-wall construction and thick glass fiber insulation, the oven minimizes heat loss and improves energy efficiency while maintaining a stable internal temperature. The horizontal recirculating airflow system, powered by a high-volume fan, distributes heat evenly through perforated stainless steel walls, delivering excellent thermal uniformity and repeatable results.

The oven supports a maximum temperature of 260°C (500°F) and reliably meets set temperature requirements for demanding laboratory and production tasks. A pressure relief panel and built-in exhaust fan enhance safety, especially when handling flammable solvents, while also supporting effective moisture removal during drying and sterilization processes.

Built with welded construction, heavy-duty gaskets, and proven Despatch engineering, this oven offers long-term reliability for laboratory use. The chamber design minimizes contamination and supports HEPA-filtered recirculated airflow, with the ability to operate in an inert atmosphere to prevent oxidation—making it ideal for thermal and reliability testing of electrical insulating materials and other sensitive applications.

Temperature Control and Safety

Microprocessor based temperature and hi-limit controller for precise temperature control and safety. Each laboratory oven undergoes a rigorous performance test to ensure it meets strict quality standards, highlighting the importance of reliability and consistency in oven performance.
