This Corning® universal optical microplate sealing tape is made from plastic and is ideal for microscopic observation of protein crystals. The high optical quality allows use for detection coupled with PCR systems such as real time PCR. Pressure-sensitive tape ensures tight sealing to minimize evaporation and enables oil-free operation when used with thermocyclers with heated lids. Suitable for use between -70 and 100°C, and compatible with commonly used aqueous solutions and organic solvents. Nonsterile. Material: Plastic. Plate Format: Sealing Tape. Feature: High Optical Quality. Surface Treatment: Not Treated. Corning® #: 6575.
