This is a commercial product that has been sold and successfully operated by a major international laboratory. Contact Thoughtventions with furnace specifications for a quote.

Fully Transparent Transparent Furnaces Thoughtventions offers a fully transparent furnace that offers full view of a sample at temperatures of up to 700 °C, along with precision temperature control and computer data acquisition in a variety of sizes. The High Temperature Transparent Furnace shown left is a resistively heated, uncoated quartz tube furnace that has been operated continuously at 700 °C. This is a commercial product that has been sold and successfully operated by a major international laboratory. Contact Thoughtventions with furnace specifications for a quote.

Multizone Transparent Furnaces Thoughtventions offers a multizone transparent furnace designed for organic crystal growth with precision temperature control and computer data acquisition in a variety of sizes. The High Temperature Transparent Furnace shown left is intended for use in organic and inorganic crystal growth. Materials can be inspected throughout the processing cycle, immediately identifying the precise temperature of melting or the creation of crystal defects. Standard transparent furnaces rely on gold-coated tubes that contain the heat but obscure visibility. The 700 °C multizone transparent furnace (shown left) creates an important crystal growth opportunity, allowing ready (and microscopic) inspection of commercially valuable materials during growth.

Custom and semi-custom furnaces of this type can be purchased at a customer specified maximum pressure and temperature. Contact Thoughtventions with furnace specifications for a quote.

High Temperature High Pressure Inert or Reducing Gas Furnaces Thoughtventions offers a wide variety of High Pressure (up to 1350 atm) High Temperature (up to 2000 °C) furnaces designed to run in inert or reducing gases. Custom and semi-custom furnaces of this type can be ordered with high at specified pressures, temperatures, and atmospheres. Contact Thoughtventions with furnace specifications for a quote.

High Temperature Vacuum Furnaces Thoughtventions offers a wide variety of High Temperature (up to 2000 °C) vacuum furnaces capable of running at pressures down to 10^-6 torr. The furnace shown left uses proprietary flexible seals between the alumina furnace tube and high vacuum standard conflat flanges in order to sustain the vacuum. Custom and semi-custom furnaces of this type can be ordered with high at specified pressures, temperatures, and pressures. Contact Thoughtventions with furnace specifications for a quote.

Workpiece Viewing Furnaces Thoughtventions offers optical systems incorporated into its furnaces that allow visual inspection of the hot zone of a furnace operating at a wide range of temperatures and pressures. Viewing of an object in the hot zone can be performed using optical access through the furnace wall (viewport, fiberoptic, endoscope, or transparent wall) or by using a cooled camera inside the furnace. Shown here is a sample image at 1000 °C illuminated by a quartz halogen lamp and short wavelength filtered. At Thoughtventions we have demonstrated (and can perform for you): viewing of objects in a furnace at 1000 °C, visual detection of melting, surface impurities and liquid circulation patterns in silicon at 1600 °C, gas cooled endoscopes that operate in furnaces at 1000 °C and microscopic imaging of sintering during the sintering process.
