1000℃–1700℃ Large Vertical Split Tube Furnace

Product Description

The GWL-LKQGA series vertical split tube furnace is designed for high-temperature heat treatment, sintering, melting, and material testing in laboratories, universities, and industrial R&D facilities.
It offers a wide working range from 1000℃ to 1700℃, with programmable control, uniform heating, and multi-zone temperature configuration.
The furnace adopts split vertical chamber design, making loading and unloading easier, especially for long samples and batch processing.
Suitable for ceramics, metallurgy, electronics, glass, chemicals, refractories, new materials, and metal/non-metal samples.
