A 50 µm heat-resistant polypropylene sealing film with a 25 µm layer of acrylic adhesive designed for thermal cycling applications. (Not recommended for PCR plates with narrow or irregular sealing surfaces: ThermalSeal 2™, AlumaSeal®, ThermalSeal A™, or ThermalSeal RT™ series films are better in such instances.) Each sealing film measures 79.4 x 135.1 mm and offers sufficient sealing area for all PCR plates. Length between th…

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 (below), 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…

ThermalSeal® MiniStripsTM 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 19.0 x 97.3 mm, including two removable positioning tabs. The long dimension with tabs removed is 76.2 mm. Each package of 200 contains 50 sheets of four sealing film…

ThermalSeal RTTM sealing films combine an optically transparent polyester sealing film with a strong, ultra-smooth, non-absorbing, non-fluorescing medical-grade adhesive for superior performance in real-time PCR applications. In place of the customary paper backing, ThermalSeal RT sealing films have a plastic liner which is easily removed before use and contributes smoothness and extreme optical clarity to the adhesive. Dimen…

ThermalSeal RT2RRTM 50 µm polyester sealing sealing films for real-time PCR are sized to fit within the edges of raised-rim 96-well plates. The same consistent ultra-high optical clarity as Excel's ThermalSeal RTTM sealing films (above) makes possible more reproducible, reliable, and consistent DNA amplification measurements. An inert, strong, temperature-resistant adhesive assures reliable sealing around each well. Two end ta…

The encapsulated silicone adhesive is non-tacky until pressed against the sealing surface, at which time adhesive is released only in sealing areas to form the strongest available heat-resistant seal around each well on the plate. Adhesive on non-sealing areas of the film, such as directly over sample wells, remains encapsulated and inert. Excel ThermalSeal RTS films are sized to fit within the edges of raised-rim 96-well plat…

AlumaSeal CSTM sealing films are specially formulated 50 µm aluminum foil sealing films with a 50 µm layer of acrylic adhesive that withstands cold storage at temperatures to -80 °C. Unlike other sealing films in the AlumaSeal group, AlumaSeal CS sealing films are not recommended for PCR or thermocycling. A single non-perforated end tab simplifies application. Simply hold the tab and strip the backing from the body of the seal…

Texan reagent reservoirs are reusable - an environmentally sound alternative to disposable reagent reservoirs. Their extra-large capacity means fewer refills and time saved. The V-shaped basin is compatible with both eight and twelve-place multiple pipettors with minimal reagent waste. Lids are removable - attached with ball and socket hinges - and latch tightly for secure storage of left-over reagents. With lids c…
