SNOL 420/300 LSN11

A new laboratory oven SNOL 420/300 is designed for thermal treatment of various materials up to 300°C. This electric oven is designed for treatments such as drying, heating, thermal testing, aging and similar purposes in an airflow environment. Forced air convection allows a homogenous temperature distribution during all process, which ensures optimal results as well as good technical parameters ensure high-quality results. This oven is also available in economical version LSN41 (without buzzer and airflow speed controller). The oven can be used in scientific laboratories, educational institutions, medicine and industry.
