Easily pierceable, 70 µm thick, polyethylene with acrylic adhesive, EZ-PierceTM sealing films allow direct sample recovery with single or multichannel pipettors and robotic probes. Dimensions are 82.6 by 142.9 mm for 96-well plates.

• easily pierceable with pipet tips or robotic probes
• inert, chemical resistant
• functional temperature range -40°C to +90°C

* Completing application of sealing films by pressing with the accessory plate roller assures a secure uniform seal around all wells.

With a 70 µm polyethylene top layer and inert white polypropylene and acrylic adhesive sublayer, this easy-piercing sealing film allows direct sample recovery with single or multichannel pipettors and robotic probes. The adhesive-free zone above each well prevents adhesive fouling of the pipet tip or probe, ultimately minimizing the amount of adhesive that comes into contact with the sample. Dimensions are 79.4 by 142.9 mm for 96-well plates.

• clear zone above each well is free of adhesive and easily pierceable
• clear zones and end tabs facilitate well alignment and accurate positioning
• inert, chemical resistant
• functional temperature range -40 °C to +90 °C

Also useful for protecting contents of plate from contamination during multiple manual reagent additions over time. X-PierceTM sealing films 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. Dimension are 79.4 x 145.5 mm. Sterile product is packaged in 100 µm tamper-evident bags of 25.

• protect samples and limit evaporation, short-term
• temperatures -40 °C to +90 °C
• special hairline X-cuts and thin adhesive prevent fouling or occlusion of probes and tips
• sealing film reseals for continued sample protection after sampling

Applications in Sonication and Cell Disruption

X-Pierce precut sealing films are also recommended for protection of samples in 96-well plates from splash-out during sonication using Microtips and Multi-Element Probes with ultrasonic appratus available from Sonics & Materials, Inc.
