[labnetwork] HMDS lifetime in YES oven

[Lewis,William]

Hi Chao,

The HMDS in our YES Oven is many many years old and no issues at all with the process.  As long as it’s not exposed to air it should be fine.

Dear Lab Network,

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!


Best,
Chao
