At UC Berkeley Microlab we use disposable Tyvek "bunny suits", caps |
and booties plus net shoe covers under the booties. In addition, lab |
members wear nitrile gloves. |
We provide gowns as part the monthly access fee. Each lab members |
keeps their own in their "gowning box". Gowns gets changed when they |
show wear and tear and typically last about a week. Lab members are |
given a sheet of tacky labels so they are easy to identify when in the |
lab. |
We have not had issues with this gowning protocol effecting yield. |
When we opened in 1984 we did what industry did, we engaged a gowning |
service. This turned out to be a mafia-style gowning service. We |
showed them the door when we saw a regular pattern of cheating us. We |
determined fabric gowns were more bother than worth. |
With 350 lab members we have not regretted our decision and no |
intentions to revisit the issue as we move to our new, Marvell |
Nanofabrication Laboratory. |

While a bit of a divergence from the original topic, I have hundreds |
of blue dacron clean room suits that I will sell at a quite reasonable price. |
Prior to our movement into Duffield Hall 5 years ago, we owned our |
own gowns and paid to have them laundered ( about $5 per set). As we |
are a high use facility we probably owned a thousand of them. I |
still have many of them left. |
We currently rent our gowns from a service that provides clean room |
laundry service. It works well. |

Dear Labnetwork Members, |
Having been 35 years in photolithography I visit Laboratories like yours globally, I would like to share with you my humble observations.. |
NOT ALL BUDGETS ARE CREATED EQUAL....What works well for one does not mean it is the most economical choice...only means you have the money. |
1) "Launder Your Own" seems to be globally the number one choice and of course the most budget forgiving.. It is the most troublesome as you need to assign staff/students to take care of this. It can be a headache to keep a constant fluidity of these garments into the cleanroom at certain times of the year. Budget vs. Headaches......I think budget wins... |
2) "Hired Outside Services" Expensive initially to buy the garments and pay for laudering services. Depending on your geographical location it can be expensive to maintain. |
3) "Hired Outside Services" Rent the garments and laundering services. |
Depending on number of students I think the most expensive in the long run. |
4) "Throw Away Garments" unless you buy big quantities at a good price and the wear n tear is resonable low, it can be expensive also.... |
In my opinion.....your budget determines your choice. |

I agree 100% with John from Purdue that the needed cleanliness of your Labs including lab garments absolutly is dictated by the requirements of your research...but blessed are those with a six million dollar yearly operating budget...not your average typical budget.. |
Just an after thought... |
