These 100-µm thick vinyl films are 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. For long-term protection after sampling, a continuous film should be applied as a second layer. Measures 79.4 x 145.5-mm.
