Microscope Slides for Botany

As a supplement to the models you can now also obtain microslides from 3B Scientific. Your students will marvel at the invisible wonders that become apparant under the microscope.

The thickness of the slides is individually chosen to show the maximum resolution of the structural components. Particular attention is paid to the staining techniques which guaranteee the best possible clarity and contrast and permancency of staining.

As a teaching aid many microslides are delivered with an accompanying text, in which the morphological structures, the systematic and physiological contexts as well as general-biological prinicpals are explained.
