Furnace tube is sealed by stainless steel vacuum sealing flanges, it can be used under vacuum and other gases condition. This tube furnace is an ideal tool for sintering all types of materials/chemical. Great for labs or college scientific research use. These furnaces have built-in
Vacuum carbon tube furnace is high temperature and high vacuum resistance furnace with graphite.The highest working temperature is 2000 ℃ ~ 2400 ℃. This series products are widely used in inorganic materials (such as ceramic seal, silicon carbide, zirconium oxide, zinc oxide, alumina, etc.), and metal materials, such as hard alloy in vacuum or protective atmosphere sintering preparation
aliquot is placed manually or by means of an automatic sampler into a graphite tube furnace. The sample aliquot is then slowly evaporated to dryness, charred (ashed), and atomized. The absorption of lamp radiation durin g atomization will be proportional to the selenium concentration. 2.3 The typical detection limit for this method is 2 ug/L.
Markets & Solutions Our high-quality solutions, components and materials made from specialty graphite and composites are used in industrial sectors that determine the future: chemical and industrial applications, automotive, aerospace, solar and wind energy, semiconductor and LEDs as well as in the production of lithium-ion batteries and other energy storage systems.
Shimadzu provides the industry with improved sensitivity and reliability for analysis of ultra trace samples through the digitally controlled technology graphite furnace atomizer. Two versions of the graphite furnace are available: the GFA-7000 is used with the AA-6200.
A comparison is made of calculated and experimental values of the characteristic mass, m XXX for 40 elements atomized in standard graphite tubes using integrated absorbance signals. The theoretical calculation involved a simplified model of vapor diffusion from the tube center toward their ends for a furnace isothermal both in time and over its
