# Vacuum Conditioning

<span style="mso-bidi-font-size: 9.0pt; font-family: 'Open Sans';">Motors are supplied pre-baked to 200 °C in 1 x 10<sup>-6</sup> mbar pressure for 24 hours and vented with dry Nitrogen before vacuum packaging. They may still adsorb water in storage and handling so a 24-hour bake by an AML stepper motor drive, with an adequate pump is recommended to achieve UHV-compatibility.</span>
