Thermo Scientific? Superfrost Plus? & Colorfrost Plus? slides hold tissue sections on permanently without the need for expensive coatings in IHC and Anatomical Pathology applications. This treatment reduces tissue loss during staining as well as hours of slide preparation. Slides electro-statically attract frozen tissue sections and cytology preparations and feature a chemistry similar to silane, although optimized to improve application performance. Each slide has a 3/4 in. printed tab and features two “+” signs at the bottom of each slide to signify that this is a Plus Adhesion slide. The printed tab is impervious to virtually all common laboratory chemicals and reagents. Available in 10 color choices.
