<p class="MsoNormal"><span style="color:#1F497D">The cleanroom gloves are not meant to be used with chemicals. The gloves are worn to keep human skins, oils and other contamination from the wafers and equipment. You should always use the proper chemical gloves
over the cleanroom gloves when working with chemicals. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Companies like VWR and Cole-Parmer publish chemical resistant charts of gloves meant for that application.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">My rule of thumb is that the cleanroom gloves are good for 30-40 minutes before skin oil starts to leak through, so we always double glove and strip the top pair off every 30-40 minutes. The first pair of gloves
comes off after you have left the cleanroom.<o:p></o:p></span></p>

<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Recently I had issues with the Nitrile gloves in our cleanroom and I was exploring options to get a better one, its seems that Nitrile gloves are not good with acetone .It has high preamble rate than latex gloves. Based on my internet research
Nitrile gloves are mostly used in the cleanroom, especially in semiconductor/medical production.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Major of my users do use the Acetone and there is always a chance that they will get in contact with acetone, especially when they clean the spinner with acetone. And I am concerned because of this. I want to have your opinion regarding
this before I look into my options.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My vendor who supplies gloves recommends double donning the nitrile gloves, so that if the user gets in contact with acetone/solvents they immediately remove the top gloves if exposed to acetone. Else wearing the nitrile glove first and
a latex over.<o:p></o:p></p>
