Subject: [labnetwork] PVC piping |
Dear Colleagues, |
There are some new classes of PVC piping (and related joining techniques) marketed for use in ultra pure water applications including 18 MOhm levels. Are there any users in our network who used similar piping materials? How do they compare to PVDF or PP piping materials? What are your assements about installation, serv... |
Thanks for your help, |
Volkan |

My initial concern was with organic compounds (TOC) leaching from the PVC pipe and cement, but it appears this new material has low extractables. The other concern I have is with the smoothness of the pipe joints. Any crevices or beads in the joint would invite bacteria growth. |
I did not dig too deeply into the specifications, but the following link from one supplier may be of some use: |

It appears there is training required to acquire the skill set needed to properly use the system, not unlike with PVDF fusion. |
I?d also be curious to see the cost difference between the two systems. |

We would be very interested in results on this. We have been using PVDF on the supply side and Polypro on the return side for most Nanolab construction in the last 10 years. |

Subject: [labnetwork] Help with Silicon on Sapphire |
Message-ID: <DA25159AE3245C4F9094656F663E84D20906AB5ADF@USFMAIL2.forest.usf.edu> |
I have researcher that wants to grow a thermal oxide on 6000Ang epi layer on sapphire substrate. I have no experience with this material and the documentation seems to be scarce. I don't want to burn up the substrate by doing something foolish as they very expensive. any help would be greatly appreciated! |
1. is this material process compatible with standard silicon processes, can I use the same tube as I do my regular dry oxidation and not worry about contamination. |
2. What heat-up and cool-down rates should I use, and are there any temp limits I need to be aware of? I've read that thermal expansion can be a problem. |
3. Can I use the RCA clean process? I'm worried about the SC1 solution attacking the Sapphire. |
