The EasyDip Slide Staining System is a user-friendly approach for staining your microscope slides. Jars can be loosely joined to each other laterally, therefore making sure they are kept in the same order when moved around on the lab counter. As an extra benefit, they are available in 5 different colors to help better identifying contents or applications. The 12-position vertical slide rack is only included with 1219D64. Purchase the EasyDip Slide Staining Rack seperately (1219D67).
