Has  anyone on BEE-L had any experience with the Varrox evaporator from
Andermatt BIO CONTROL?  Or can anyone here read German well enough to chase
this idea down?

Quoting from http://www.mellifera.de/oxneu.htm

"from 95 beekeepers from seven European countries tested the Varrox®
evaporator of the company Andermatt BIO CONTROL AG.  The data of altogether
1,509 treated bee colonies were entered and analysed.  In the field test
altogether 797,744 mites and 197,169 bees were counted..."

An oxalic evaporator is also described at
