Tube Furnace

Lindberg Blue M (1″)

Overview

Tube Furnace

The Lindberg Blue M 1-inch Thermal Furnace is a tool for chemical vapor deposition (CVD), annealing, and oxidation at low pressure or atmospheric pressure and with or without process gases in a 1 inch diameter quartz tube.聽 The tube pressure, temperature, and gas flow rates are tunable.
