Product Overview
Multi-Channel Tube Furnace for Parallel Material Research
Brother Furnace dual and multi-tube furnace is developed for universities, research institutes, catalyst laboratories, battery material R&D centers, ceramic research labs and industrial testing facilities that need higher sample throughput and better experiment efficiency.
Compared with a single tube furnace, a dual or multi-tube furnace can process multiple samples in one equipment platform. Depending on the process, the furnace can be designed with shared heating for same-temperature experiments or independent heating modules for different temperature conditions. Each tube can also be equipped with independent gas inlet, outlet, flow control, vacuum valve or exhaust line when different atmosphere comparison is required.

FAQ
Dual & Multi-Tube Furnace FAQs
Here are common questions customers ask before purchasing a dual tube or multi-tube furnace for parallel material testing and atmosphere comparison.
What is a dual tube furnace?
A dual tube furnace is a tube furnace with two furnace tube channels. It allows users to process two sample groups at the same time, compare different conditions or improve laboratory testing efficiency.
What is the difference between a dual tube furnace and a single tube furnace?
A single tube furnace processes one sample batch or atmosphere condition per run. A dual or multi-tube furnace can process multiple samples or conditions in parallel, which is useful for R&D screening and comparative testing.
Can each tube have independent temperature control?
Yes. The furnace can be designed with shared heating for same-temperature processing or independent heating and control for each tube when different temperature conditions are required.
Can each tube use a different gas atmosphere?
Yes. Each tube can be configured with independent gas inlet, flowmeter, mass flow controller and exhaust line for atmosphere comparison experiments.
Can each tube be evacuated separately?
Yes. The vacuum system can be designed as shared vacuum or independent vacuum lines with separate valves, depending on whether each tube requires separate evacuation control.
How many tubes can be customized?
Dual tube, triple tube and four-tube designs are common. More tube channels can be customized according to tube diameter, heating layout, gas line design and installation space.
Can the furnace be used for CVD?
Yes. The furnace can be configured with gas inlet/outlet, flow control, vacuum system and suitable tube material for CVD or gas reaction comparison experiments.
What information is needed for quotation?
Please provide tube quantity, tube diameter, heating zone, maximum temperature, working temperature, whether independent heating is required, gas type for each tube, vacuum requirement, sample size, power supply and destination country.
