Retractable Effusion Cell
The retractable effusion cell allows re-filling an effusion cell without venting the growth chamber. The retractable cell can also be used to protect the effusion cell charge from oxidation when the growth chamber is vented. The cell is separately pumped and comes with a bakeout heater jacket.
The retractable cell is available with NW63CF and NW100CF port sizes. The max. crucible volume is 100 cc for a dual filament cell.
