This inexpensive procedure utilizes the Gomori Iron
reaction method. It avoids the time and preparation of caustic
and poisonous chemicals. Each dropper contains two glass reagent
ampoules that, when broken and mixed, are ready to stain up to
four slides at a time. Each package contains 12 dropping units
and Nuclear Fast Red counterstain. The plastic packaging box serves
as a humidity incubator for the slides. Slides have long shelf-life.
Positive Iron Control Slides are also available separately.
