| Quartz Tube amp; Sample Holder | 、Quartz Tube Size: 4.33" O.Dx4.05" I.D x16.2" Length  、3" diameter Sample holder is inserted to sliding flange, which is made of    quartz  、One 3" diameter AlN wafer is placed in the center of holder for annealing    sample up to 3" dia.  、AlN has very high thermal conductivity, which provides the best temperature    uniformity in the sample area  、The sample holder is removable from flange | 
| Vacuum flange | KF-D25 High Vacuum Flange is made of stainless steel with double hi-temp. silicone O-rings, needle valves.Sliding flange make an easy way for sample loading. 3" Quartz sample holder.Insert-able thermal-couple for accurate measurement. | 
| Water Cooling Jacket | 、Cooling water is required.  、Please make sure the flow rate of cooling water is ≥ 10L/min, water temp.     < 25ºC; pressure gt; 25 PSI.  、We suggest using the EQ-KJ5000 Series recirculating water chiller as a    cooling system (please order separately at related products below) to     save water. Warning: This RTP furnace's max dwelling time shall be less than 600 seconds at 1000ºC ~ 1100ºC with tap water, otherwise O-ring may melt. With use of a recirculating water chiller, this holding time can be extended to 1200 seconds. | 
| Flow meter | One flow meter is installed on the front panel to adjust gas flow from 0 - 160 ml/min | 
| Power input | 208-240 AC, 50/60 Hz single phase, 9 KW Max. (gt; 60A breaker required) | 
| HV StationHigh Vacuum Station | Structure | 、Mobile cart size: 600 (L)x600 (W)x700(W), mm  、Max. Loading:    600 Lbs on top  、Molecular pump control Panel :  LCD digital  、Diaphragm Pumpand Turbo Molecular Pumpare installed inside the steel    case. | 
| Vacuum Degree | 6.3E-5 mbar (with 4" RTP tube furnace in 40 minutes) | 
| Control panel | 、One button operation- the diaphram pump and the turbo molecular pump    will start after pressing "start" button.  、System controlled spining speed- the controller will control the speed of    the turbine spining up and down according to the vacuum level and leaking    rate of the reaction chamber.  、Self protection- the system will protect the pump from damage by    overheating and overcurrect if the leaking rate of the reaction chamber is too    high to achieve high vacuum.   、LCD screen- double lines parameters checking interfacemake the working    easier to be handled. |
