X-Pierce™ sealing film is a 89μm vinyl film with a 18μm 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. Also useful for protecting contents of plate from contamination during multiple manual reagent additions over time.
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. Dimension are 79.4mm x 145.5mm.
