Optimal Performance for Traditional/Classic PCR
ThermalSeal® Film
- Designed for basic PCR protocols
- Withstands temperatures from -40°C to 120°C
- End tabs facilitate film to plate alignment
- RNase/DNase/nucleic acid free
ThermalSeal® a 50 µm polypropylene film with adhesive formulations is optimized for specific PCR applications. Traditional film dimension measures 135.1 x 79.4 mm (123.1 mm without end tabs) and offers sufficient sealing area for most PCR plates. Optimal Performance for Traditional/Classic PCR. ThermalSeal sealing films are not pierceable. For applications where piercing with pipet tips or robotic probes is required for product recovery, see AlumaSeal II sealing films. For real-time PCR applications where maximum optical clarity is required, see ThermalSeal RT and RT2RR sealing films.
Note: Not recommended for PCR plates with narrow or irregular sealing surfaces: AlumaSeal®, ThermalSeal A™, or ThermalSeal RT™ series films are better in such instances.
ThermalSeal® MiniStrips™
ThermalSeal® MiniStrips™ sealing films are identical to ThermalSeal sealing films (above), but designed for sealing only one or two 8-well rows at a time on PCR plates or strip tubes. They are now supplied in convenient sheets of four. Each sealing film strip is 97.3 x 19.0 mm, including two removable positioning tabs. The long dimension with tabs removed is 137.8mm. Each package of 200 contains 50 sheets of four sealing film strips.
- Two tabs on each strip for easy application and removal
- Perforated tabs can be removed or sealed around plate edge
- Heat resistant, recommended for temperatures from -40°C to +120°C
- Certified DNase-, RNase-, and nucleic-acid-free
ThermalSeal® 2™ Sealing Films for PCR
These improved films for classic thermal cycling applications consist of a 50 µm polyester film with a 41 µm layer of acrylic adhesive. Compared to the original ThermalSeal® films, ThermalSeal® 2™ films offer better adhesion, reduced evaporation, longer end tabs for easier handling, and less tendency to tear during removal from the plate. Each sealing film measures 79.4 x 139.7 mm and offers sufficient sealing area for all PCR plates. Length between the perforations with end tabs removed is 125.1 mm. (Not recommended for raised-rim plates; see ThermalSeal A™ films.) ThermalSeal 2 sealing films are not pierceable. For applications where piercing with pipet tips or robotic probes is required for product recovery, see AlumaSeal® sealing films. For real-time PCR applications where maximum optical clarity is required, see ThermalSeal RT and RTS sealing films.
- Heat resistant, recommended for temperatures from -40°C to +120°C
- Better adhesion; reduced evaporation
- Longer end tabs for easier handling
- Does not tear during removal from the plate easier to apply than aluminum foils, no tendency to roll back
- Certified DNase-, RNase-, and nucleic-acid-free
