ROTI®Seal is used to seal the edges of the coverslip. Therefore, it protects the mounted specimen reliably against damages caused by air humidity. ROTI®Seal is solid at room temperature.
Prior to use it is melted on a water bath (max. 50-55 °C), then it is applied around the edges of the coverslip by using a pipette or a glass rod. Exposure to light (day-light is sufficient) allows the sealant to harden within a short time.
