ThermaSeal RTSOptically Clear Silicone Adhesive provides an extremely strong seal to minimize evaporation The silicone adhesive is non-tacky until pressure is applied to the sealing surface which then creates a secure bond around the wells and perimeter of the plate Also ideal for dry samples (e g soil seeds insects etc ) because the non-activated adhesive above the wells remains non-tacky A roller or sealing paddle is highly recommended for use with this product to ensure consistent and adequate pressure is applied during the sealing process Certified DNase- and RNase- free Now available 25/ pack you asked we listened Handling and plate positioning is simplified as a result of the non-tacky adhesive Chemically resistant to DMSO acetonitrile and methanol Ideal for use with flat-top raised-rim and non-skirted PCR plates High optical clarity and low auto-fluorescence Available in roll format for automation ThermalSeal RTS Roll-Seal A complimentary sealing paddle is included in each
