Essential Parameters
|
Evaporator |
Phase of adsobate transforming from liquid to gas by evaporator in room temperature, implements test requirements |
|
Adsorption Pressure |
P/P0 is less than 1 (p0 is saturated vapor pressure of adsobate in adsorption temperature) |
|
Vacuum Pump |
Special corrosion – resistant vacuum pump, molecular pump |
|
Pressure Sensor |
1000 Torr, 10 Torr, 1Torr |
|
Sorption Temperature |
-196 oC is provided by liquid nitrogen in low temperature Dewar flask; 0 ~ 50 oC is provided by thermostatic water bath. |
|
Number of Gas Inlet |
Providing separate gas intakes according to customer requirements. (Number of intakes is multiples of 4). |
|
Gas Recovery |
Effective cold trap system prevents from polluting vacuum pump and environment by vapor. |
