OvenOVEN (420L) with temperature up to 300°C, SNOL 420/300 LSN11 ST


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 homogeneous temperature distribution during the process, which ensures optimal results, moreover, good technical parameters ensure high-quality results.
