A laboratory oven, also known as laboratory heating oven, lab drying oven, lab heating oven, lab drying stove, drying oven or simply lab oven is a a type of oven used in laboratories to dry glassware, compounds, and other heat-resistant materials, using a stream of heated air or inert gas.
In some countries, the term etuve or a derivative is used for lab ovens.
Lab ovens consist of an insulating metallic chamber, accessible through a door. Heating elements run through the stainless steel clad walls, while an inner fan circulates the air inside the oven chamber, keeping the temperature constant in all the points. A thermostat controls the temperature inside, which can be adjusted from a series of buttons. Most lab ovens can maintain an inner temperature between 30 and 300 °C. Some lab ovens are also capable of sustaining vacuum.
Lab ovens can be purchased from various chemical and medical suppliers. They can sometimes be purchased from eBay.
