MTI Corporation provides the high purity quartz tube as a replacement part for high-temperature tube furnaces in universities, companies, and national labs. This tube is designed for Fluidized Bed Vertical Tube Furnace and it can be used at operating temperature up to 1200ºC.
Purchase Notes: Please make sure the specification of the tube meets your need before making a purchase. Since Nov 10, 2016, we have no longer accepted return delivery of any tubes due to the fragile nature of the materials. All tubes are not refundable, not exchangeable, nor covered under the warranty (Consumables). We apologize for the inconvenience. Please check the package for damages before accepting the delivery. For more information or damaged upon arrival please contact us.

SPECIFICATIONS

Feature	One quartz tube with bottom frit and enlarged space for particles processing Two Ends: 25mm O.D, 22mm I.D; Central: 50mm O.D, 44mm I.D, for detailed size, please refer to the picture left. Central enlarged area ensure the high aerodynamic performance Frits with forced convection design can trap the particles within the central heating area Frit: 15~40 microns porous, 22mm O.D x 4mm thick
Dimensions of Both Ends	O.D: 25 mm ± 0.5 mm I.D: 22 mm ± 0.5 mm
Dimensions of Central	O.D: 50 mm ± 0.5 mm I.D: 44 mm ± 0.5 mm
Tube Length	533 mm (21")
Max. Operating Temperature	1200ºC
Application Notes	For vacuum sealing, please choose vacuum flanges at the related products below This quartz tube is excellent for DIY tube furnace below 1200°C Vacuum pressures may only be safely used up to 1000°C The flow rate for gases should be limited to <200 SCCM for reducing thermal shocks to the tube Quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa In order to get longer tube service life, Please use quartz or alumina crucible to carry the sample, instead of loading the sample directly inside the tube, please click the picture below to choose one crucible boat:
