[Histonet] guidelines for using a microwave designated for food, but used to heat up histogel

[John Garratt]

NEVER use a microwave to heat up Histogel regardless of ithe microwaves pedigree, especially for cytology specimens. There is a tendency to overheat the gel and thereby compromise the specimen, especially for IHC. Use a warming block where the temperature can be accurately controlled.

I just found out they used the microwave in our lab lounge to heat up histonet which was opened and being stored in our gross area refrigerator.
