Laboratory 3000℃ Arc Melting Furnace For Small Batch R&D
Introduction
The VAF-200 metal melting furnace is a compact arc melting furnace. It allows repeated melting of alloy ingots by flipping them without breaking the protective gas atmosphere, and can prepare multiple samples simultaneously. It is an ideal device for preparing refractory metals and metal carbide samples in universities and research institutions.
Technical parameters
