Product Features

Save money and maintain quality

By using low reagent volumes, the Leica ST4020 linear stainer supports your laboratory to reduce waste and cut reagent costs. Optional agitation, running fresh water, and customizable protocols help to maintain a consistent diagnostic quality.

Accommodate your laboratory’s workload
