A 48 um soft non-permeable aluminum foil sealing film with 30 um layer of strong acrylic adhesive. FoilSealTM sealing foils remove cleanly from plate surfaces with no adhesive stringing, residue or contamination. Each sealing foil measures 78.3 x 129 mm and offers sufficient sealing area for all plate types (e.g. flat top and raised-rim). Chamfered corners result in no plate overhang for robotics applications. Features one end…

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…

X-PierceTM sealing films are 89 µm thick vinyl with a 18 µm thick adhesive layer, designed for temporary protection from contamination and evaporation for samples in 96-well plates. A precut "X" over each well creates four flaps that easily bend downward when pushed by a robotic probe or pipet tip, allowing sample access without coring or adhesive fouling. A thin adhesive layer and special hairline cuts separating the X-Pierce…

A 140 µm thick hydrophobic porous rayon sealing film including medical-grade adhesive for tissue culture plates, bio-blocks, and 96-well plates where gas exchange is necessary for cell or bacterial growth. AeraSeal sealing films minimize cross-contamination, spillage and evaporation. They allow uniform air and CO2 exchange for all wells, unlike plate lids which favor exchange for wells near the plate edges. Dimensions: 82.6 by…

Excel Scientific now offers adhesive sealing films on Roll-Seal™ rolls for use with high-throughput automated microplate sealers. Film rolls, constructed on three-inch-diameter plastic cores, are compatible with most common adhesive sealers (Brandel, Thermo-Fisher/Abgene, FluidX, KBiosystems). The Roll-Seal format provides reliable and efficient sealing at a lower cost per plate with minimal user intervention. Robust static-fr…

SealPlate® 50 µm thickness polyester sealing films minimize evaporation, prevent spillage and contamination between wells, and provide a secure seal, not just a cover. Secure sealing of all wells eliminates "edge effects" in sensitive ELISA assays. SealPlate sealing films can also be used with tissue-culture plates for short-term storage, incubation, and containment of biohazards. SealPlate sealing films are non-pierceable. Ea…
