For very limited lab or storage space, the simple solution I can think about will be separate secondary containers with different colors, and put different color stickers on the bottle caps. Also put a big color chart beside the storage cabinets and benches to clarify which is which. |
I totally agree with Tony, no matter how great foolproof your system is, there will still be someone making mistakes. Wish our system can provide some idea to help. |
Best, |

To avoid this, one of the suggestions we have received from our OLSEH is to store HF in a different coloured bottle (currently all acids are stored in white translucent polypropylene bottles which are properly labelled). Accordingly, we had considered storing HF in opaque, brown colour HDPE bottles. However, that was not deemed acceptable by a section of users saying bottles should be translucent so that acid level inside can be judged. |

Subject: [labnetwork] Explorer 14 gate valve adjustment. |
Message-ID: <CAPzRSB2USUPULuwP-QvZ004-dFSuD60QZvNgCCTrLnqCH83OvQ@mail.gmail.com> |
Hello, |
We are currently trying to adjust the cryogate valve intermediate |
position on our Explorer 14 sputtering chamber. The gate valve in question |
is a "VAT 64046-PE48-0008/0053 A-1142418" Photo attached. |
Any information/guidance on how to do this would be greatly appreciated. |
Tech service is giving us a hard time with getting someone to talk to. |
Thanks! |
