I had asked CAP about this question ..........it makes sense to monitor reproducibility with regards to tissue processing but CAP would not comment on microwaves used for say simply heating agar for cell blocks!

Nirmala:

  As you know, QA records require procedural consistency. Some laboratory designed microwave ovens (MWO) can monitor temperature and, as a matter of fact, the program sets the desired temp. and the time, "leaving" the MWO to set the energy level to reach both requirements.

  Those MWO usually can print a protocol log in which temp. is recorded.

  If the MWO is not lab designed, or if it does not have the recording capability, the temp has to be determined with a probe.

  The whole idea is to make sure that the tissues are subjected only to a pre-determined temp, in the same way that each day the temp. of the retort on any regular tissue processor is recorded.

  The CAP requirement is that there should be a record, either automatic or logged, with the temp. the tissues have been exposed during the processing protocol.

Hi,

 

I would like to get some feed back on this cap question

 
=0DANP. 28290

 

ARE MICROWAVE DEVICES PERIODICALLY MONITORED FOR TEMPERATURE

REPRODUCIBILITY?

THANKS
