FW: [Histonet] microwaves in labs

[Patti Loykasek]

I think we should all have a copy of  Microwave Device Use in the Histology
Laboratory; Approved Guideline. CLSI document GP28-A [ISBN 1-56238-563-1].
Also, in CAP question  ANP.29430 Are microwave devices properly vented? The
comment reads: This checklist question does not apply if only non-hazardous
reagents (and non-infectious specimens) are used in the device (e.g., water,
certain biological stains, paraffin sections). Hopefully this info will
help,but probably it will only muddy the water.
I better get back to my staining. Hopefully have not incited too much
flaming.
