Sigma Aldrich Fine Chemicals Biosciences X-PierceTM film sterile

Supplier:  Sigma Aldrich Fine Chemicals Biosciences Z72252950EA

Also useful for protecting contents of plate from contamination during multiple manual reagent additions over time. X-Pierce films are 89 mum thick vinyl with a 18 mum 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 pipette 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 film should be applied as a second layer.
