[Histonet] RE: Recycling of alcohol

[Roy, Lisa]

In my experiences with recycling of alcohol, you will never get any return over 95%.  Our lab stopped recycling the alcohol because eventually you have a ton of 95% coming out your ears, but still purchasing reagent grade 100%.  Wasn't worth it for us. Just did xylene and formalin.

Jim, yes, in my experience you are going to use this for 70 to 95% alcohol steps, not 100, unless you get a water absorber (B&R has one, at least used to).

In the past I have plenty of years of experience recycling formalin and clearing agents, however I don't have much experience with recycling reagent grade alcohols.  If we recycle waste alcohol that is 95% - 100 %, I am told that our recycled product will be 99% or above.   With that said how are others using this alcohol?   Are they using it as 100% on the tissue processors?   Are they using it in the strainers for 100%?  Are others using it as 95% instead of 100%.   Obvioulsy I am concerned that my last alcohol station on the VIP is as close to 100% as possible and the same is true for the automated stainer.

Obviously we can use the recycled alcohol for cleaning reagents on the tissue processors.   Please share with me if you are recycling alcohol to what extent are you using the recycled product.
