Horizontal Tube Furnaces

Horizontal Tube Furnaces

Deltech horizontal tube furnaces are ideal for applications in which the sample size is relatively small in diameter, but processing in inert or reducing atmospheres or under vacuum is required. The product can be placed in a combustion boat and slid into the tube from one end. Robust design and unique features such as a removable rectangular roof plug for take these units out of the realm of “catalog” laboratory models.
