Technical advantages Stainless steel plates to ensure the finish of chamber surfaces, ensure the asepsis requirement. Shelves has high intensity and it can reaches to 0.3Mpa in the pressure test which can be able to bear the long term usage. Shelves are processed by machining ,which can ensure flatness demanding level. Temperature control accuracy ±0.5℃ (adjusted by PID, in balance) Special sealing strips for doors can prevent ponding , meets the asepsis requirement. Chamber, shelves are all carried out the leak test by helium mass spectrometer. |
