Hi HistoNetters

Dave asks whether lab microwaves are any 
different behind the label.  The answer is, some 
are, and some aren't.  Many lab microwaves start 
life as kitchen microwaves, and have their 
electronics replaced.  Others are built from the 
ground up for the lab.  It's important to ask, 
and you get what you pay for.

That being said, what all lab microwaves should provide are:

°  vented cavity for safety

°  accurate, reproducible, calibrated power or temperature control

°  tested protocols for whatever application you need

°  cycle time of 2 seconds or less or continuous power option

°  agitation or stirring

A NCCLS document is in the final stages which 
will address the use of domestic microwaves in 
the lab.
