Excel Scientific’s SealPlate® ColorTab adhesive sealing films consist of 50 µm thickness clear polyester. They minimize evaporation, prevent spillage and contamination between wells, and provide a secure seal for ELISA, EIA, and similar assays. These unique sealing films include a color dot and white writing area on each end tab for plate ID labeling. End tabs with backing removed adhere to the ends of the plate and are perforated so they can be left in place to maintain plate identity even if the center portion of the sealing film is removed. Alternatively, one inscribed color-coded end tab can be removed and pasted in a laboratory notebook while the other remains on the plate for identification. Dimensions 79.4 by 146.1 mm for 96-well plates. Sealing films are supplied with five dot colors (green, lavender, orange, red, blue) in non-sterile single-color packs of 100 and in assorted packs of 50 containing five individual-color packs of 10, also non-sterile.

The Gas Permeable Clear Heat Seal is based on the Clear Heat Seal, with the addition of 3 mm slits across the width of the seal. These slits render the seal gas permeable, whilst retaining evaporation to a minimum, compared to the use of lids. The Gas Permeable Clear Heat Seal is compatible with polypropylene, polyethylene, polystyrene and cyclic olefin copolymer (COC) plates. The seal can be removed by peeling, or it can be pierced with a pipette tip manually, using a liquid handling robot or with a Pierce Plate. It can be used for insect and seed storage, as it enables gas exchange, whilst providing an inert surface with no adhesive to interfere with the well contents.
X-Pierce™ Pre-Cut Pierceable Sealing Films are useful for protecting contents of plates from contamination during multiple manual reagent additions over time. They 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 flaps combine to prevent probes from contacting adhesive and becoming occluded. The flaps return to their original position after sampling for continued protection. For long-term sample protection after sampling, a continuous sealing film should be applied as a second layer.
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 142.9 mm for standard-size tissue culture plates.
A 36 µm soft non-permeable aluminum foil sealing film with 28 µm layer of strong medical-grade acrylic adhesive, AlumasSeal II™ sealing films eliminate the need for heat-sealing devices or mats during thermal cycling. Compared to other aluminum foils, AlumaSeal II™ has less tendency to roll back on itself when removing the backing paper and conforms well to the plate during application.
