Features

· Made of Stainless Steel with double high-temperature silicone O-rings on the flange.  

· Stainless steel needle valve with 1/4" pipe adaptor and one end with KF25 port.    

· The assembly kit will seal one end of 80-82 mm diameter ceramic and quartz tube.

· Vacuum meter is installed in one side of flange.

· You may choose left side, right side or full set of flange at product option bar

Note:  You may order Digital Temperature Controlled Recirculating Water Chiller with 16L / min Flow, to cool the flange and save water.

Vacuum level

· 10E-2 torr by a mechanical pump

· 10E-5 torr by a small turbopump

· 10-6 torr by hi-speed turbopump

Warming 

· Must put a refractory tube block between the flange and the sample to avoid melting the silicone O-ring by heat radiation. Please order a ceramic block in related products.

· Please do not over tighten the three hex screws on the flanges to avoid overpressure incidents. The recommended torque is 35~40 inch-lbs.

· For liability considerations, we do not recommend or endorse the use of any toxic, flammable or corrosive gases with our flange assemblies. Please contact us with any concerns.

Application Notes

Max. furnace working temperature is 1100ºC without thermal block if tube furnace is installed with this water cold flange

If furnace working temperature > 1100ºC , suggest you use a quartz thermal block ( see related product below )

Please always use recirculating water chiller to save water and protect
