The micro–Insert 4Well FulTrac is a biocompatible, silicone insert ideal for long–term, single–cell microscopy analysis. The micro–Insert has a special sticky bottom that prevents leaking on smooth, dry surfaces, such as microscopy slides and dishes. The circular, cone–shaped format of each well allows adherent or non–adherent cells placed into the wells to sink to the bottom. Whole–well imaging can be achieved with a 20× objective. The conical–shaped wells provide excellent optical access to cells located near the edges of the well. After cell attachment, the micro-Insert can be removed by using sterile tweezers without leaving a residue. The micro-Insert 4 Well FulTrac comes ready-to-use in our µ-Dish 35 mm, High, ibiTreat dishes. Sterile, 30 pcs./box.
