Tube furnaces are used to heat a compound for the purpose of either purification or synthesis. The compounds (whether organic or inorganic) are placed within the tube, which is then heated by surrounding elements. This method allows the tube ands it contents to reach very high temperatures at a relatively low energy cost.

Across International's tube furnaces are some of the most reliable on the market. Available in a variety of sizes, zones, and with temperatures ranging up to 1800°C, Across tube furnaces are popular in laboratories around the world for their versatility.

Growing Labs provides Across furnaces at great pricing and with awesome service, pre- and post-purchase.
