Re: [Histonet] Disposal of MMA BPO Waste
I was at UPENN Vet School at the time I used this method. We sometimes had 4 to 6 bottles under the hood to polymerize. We would use Nalgene 1 liter bottles about 2/3s full and allow them to polymerize under the hood. We always sat the bottles in large Tri-Pour disposable beakers in case the bottle crack or overflowed during polymerization and then through them out in the normal waste. If we had straight MMA we added some BPO to allow it to polymerize completely. Larger amounts would be far more difficult to control the reaction in and contain it.

We sent a request to our campus Chemical Waste Management for the MMA waste mixture to be disposed of, but they are refusing because they say the mixture is too hazardous. The mixture contains 1gram of benzoyl peroxide ( BPO ) per 100mL of MMA . Chemical Waste Management informed us that MMA in the presence of BPO is highly reactive. We would like to know: for histology, how is MMA + BPO waste normally disposed of?

RE: [Histonet] Amyloidosis control tissue
Missy, It is my understanding that at this time there are no control tissues available. I myself have tried to get some from various places and have been told it is very difficult for the vendors to come by them.

RE: [Histonet] Disposal of MMA BPO Waste
This is what comes of letting people with little or no training in chemistry call themselves chemical waste mangers. Yes, methyl methacrylate is highly reactive when mixed with 1% benzoyl peroxide: it forms a hard, brittle polymer. Pour your left over methyl methacrylate and benzoyl peroxide into a disposable weighing boat and heat it overnight at 60 C and over another night at 80 C. The resultant polymer is commercially sold as Plexiglass; it can be safely disposed of as ordinary trash. A much higher concentration of benzoyl peroxide (10% or more) could explode when heated. Chemical potential depends on concentration. -Allen A.

Re: [Histonet] Block disposal
They are classified as Pathological Waste. You should see what your state's rules are regarding Pathological Waste. histot...@imagesbyhopper.com 6/21/2010 12:33 PM Would blocks be considered biohazard waste for purposes of disposal? I have blocks stored in an off-site facility and am preparing to dispose of the blocks. Can I simply allow the storage place dispose of the blocks in normal trash, or would I need to have them disposed of as biohazard trash? On a separate but sort of related issue, does anyone use the Adlex crystals to dispose of their formalin? If yes, how do you dispose of the jellied formalin, in normal trash or in biohazard trash? I know the mfr says you can put it in the normal trash, but does anyone trust this?? ;o) By the way, I am in Florida, if that makes any difference in the answers! THANKS!

RE: [Histonet] Help! In need of positive Gram Control
Go to your local drive in mart and buy you a Slim Jim, cut it in thin slices and you will have all the Gram controls you can use. You will never eat another Slim Jim. If you don't know what they are, they are sort of like a summer sausage, only thinner and guys love them. They are found usually right beside the check out register.
