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…

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…

Easily pierceable, 70 µm thick, polyethylene with acrylic adhesive, EZ-PierceTM sealing films allow direct sample recovery with single or multichannel pipettors and robotic probes. Dimensions are 82.6 by 142.9 mm for 96-well plates.Features:easily pierceable with pipet tips or robotic probesinert, chemical resistantfunctional temperature range -40°C to +90°C

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…

With a 70 µm polyethylene top layer and inert white polypropylene and acrylic adhesive sublayer, this easy-piercing sealing film allows direct sample recovery with single or multichannel pipettors and robotic probes. The adhesive-free zone above each well prevents adhesive fouling of the pipet tip or probe, ultimately minimizing the amount of adhesive that comes into contact with the sample. Dimensions are 79.4 by 142.9 mm for…
