The SHEL LAB Model SMO28-2 is the largest general purpose oven on the market (also consider the SMO38HP-2 high performance ovens for the best uniformity and functionality).

Airflow is directed evenly across all shelves and samples to ensure consistent drying, curing and baking results.

These units are especially ideal for glassware drying in core facilities.

There are several models to choose from in the forced air product line, with varying sizes and control features. The large capacity units are perfect for high volume sample and drying applications, including production processes
