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. They are available with or without a printed 96-well alphanumeric template for easy well location. The printed EZ-Pierce sealing films also have color-coding dots and white marking areas on each end tab for plate identification. (See EZ-PierceTM ColorTabTM section below for more details.) 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
• printed alphanumeric template version simplifies well location

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

EZ-PierceTM ColorTabTM sealing films consist of easily pierceable 70 µm thickness polyethylene with an acrylic adhesive. Piercing allows direct sample recovery with single or multichannel pipettors and robotic probes. These unique sealing films include a printed 96-well alpha-numeric template for easy well location and a color dot and white writing area on each end tab for plate ID labeling. End tabs with backing removed adhere to the ends of the plate and are perforated so they can be left in place to maintain plate identity even if the center portion of the sealing film is removed. Alternatively, one inscribed color-coded end tab can be removed and pasted in a laboratory notebook while the other remains on the plate for identification. Sealing films are supplied with five dot colors (green, lavender, orange, red, blue) in individual bags of ten each within the outer box of 50. Dimensions 82.6 by 142.9 mm for 96-well plates.

• printed alpha-numeric template simplifies well location
• color dots and white labeling area on end tabs for plate identification
• second tab can be separated for lab-notebook insertion
• end tabs can be left on plate even if center of sealing film is removed
• inert, chemical resistant
• functional temperature range -40°C to +90°C

With a 70 µm 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 100 µm thick vinyl with a 20 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.
