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

[John Garratt]

With regard to microwaves themselves you may find requirements  related to monitoring for microwave radiation leakage in your local regulations and the recording of such inspections. It is a radiation device.

Trouble with your cytology IHC? Check how your cell blocks are being prepared and get rid of that microwave.
