RE: [Histonet] RE: Microwave Tissue Processors
My specimens are usually rabbit joints. I've no experience using a
microwave for processing and need some advice.
Can we use a normal microwave for this purpose? And what would be the
optimum setting/temperature/time to use and processing time for each
(fixation and decalcification)? Would really appreciate any advice from
those who've been there and done that.
Thanks in advance

I work in an orthopaedics research lab as well and process many many
many mouse hind limbs, calvaria, etc. We use a microwave processor from
Hacker (milestone medical). It has decreased our time to process. We
had some trouble at the start with some of our enzyme histochemistry.
The trick to the machine is the heat. It was heating the samples up so
much that one of our stains wasn't working. After much testing we
figured out that all you have to do is decrease the temperature of the
processing and increase the time. It was basically trial and error
because the company markets these for rapid processing for surgical
We decal on the machine and we also do antigen retrieval and found that
of our antibodies worked well with it. We are still testing out the
capabilities of the machine. But it has helped this lab become more
Hope that helps.
