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.
