<p class="MsoNormal">Dear Lab Network, <o:p></o:p></p>
<div>
<p class="MsoNormal"><br>
I was wondering how long the lifetime is for the HMDS in the YES oven. On the note from the YES's website, it says " If the HMDS is more than a year old, it should probably be replaced". I would assume the "year" here starts from the HMDS manufactured date,
which is the shelf life for a brand new bottle of HMDS. Do you guys have experience on using the HMDS for extended time (like 6+ months) after the expiration date? Please let me know your thoughts and suggestions. Many thanks!<o:p></o:p></p>
