Technical Narrative

The Caplugs® Evergreen EZ-Seal™ is an acrylic adhesive microplate sealing film made from inert polyester (PET) for hermetic sealing of standard 96-well and 384-well SBS-footprint microplates. The acrylic pressure-sensitive adhesive provides a tight seal against plate flanges and well rims, preventing evaporation during PCR thermocycling, overnight incubation at 4°C, extended compound storage, and sample plate transport. The inert polyester film is fully DMSO-compatible at all concentrations — the defining requirement for compound library plate sealing in drug discovery, where DMSO carrier solvent permeates through or degrades adhesive films not rated for DMSO exposure.

The acrylic adhesive provides a stronger and more reliable seal than polyolefin heat-seal films for ambient-temperature plate sealing applications — no heat applicator equipment required, just manual pressure application from center to edges. The clear polyester film is optically transparent for real-time PCR (qPCR) plate sealing where the plate reader must detect fluorescence through the seal during thermocycling — compatible with standard qPCR instruments (Bio-Rad CFX, Applied Biosystems QuantStudio, Roche LightCycler) in top-read optical detection mode. Residue-free acrylic adhesive peels cleanly from PS, PP, and acrylic plate surfaces without leaving adhesive deposits that would contaminate subsequent plate read operations.

At $67.00 per 100/Bag — $0.6700 per seal — EZ-Seal™ delivers hermetic plate sealing at per-seal economics suited to high-volume plate processing programs sealing 50–500+ plates per day.

Plate Sealing Application Compatibility — EZ-Seal™

EZ-Seal™ acrylic adhesive films provide hermetic plate sealing for the following workflows:

Application Assay / Use Notes
PCR plate sealing 96-well, 384-well PCR plates before thermocycling Prevents evaporation during PCR — optical versions allow real-time PCR
Sample storage sealing Compound library plates, biobank archive plates Acrylic adhesive provides strong seal for long-term plate storage
ELISA incubation sealing Antibody-coated plates during overnight incubation Film seal prevents contamination and evaporation during 4°C overnight
Compound plate sealing DMSO compound library plates in drug discovery Inert polyester resists DMSO — standard compound library seal format
Cell culture plate sealing Short-term sealed transport of culture plates Acrylic seal allows brief covered transport between labs
Evaporation control Any plate requiring sealed incubation Replace lid-based evaporation control with film seal for tight closure
Plate storage between runs Sample-loaded plates between processing steps Film seal provides better evaporation control than standard lids
Plate centrifugation (pre-seal) 384-well plates before brief centrifugation Film seal withstands brief low-speed spins for sample consolidation

Apply seal by pressing firmly from center outward to eliminate air pockets. For PCR, run a brief centrifuge spin after sealing to consolidate sample at well bottom. Remove seal by peeling from one corner — acrylic adhesive releases cleanly without plate surface residue.

Chemical Resistance — Inert Polyester (PET) with Acrylic Adhesive

Inert polyester provides broad chemical resistance including full DMSO compatibility — the critical requirement for compound library plate sealing. Acrylic adhesive provides strong seal with residue-free peel removal.

Reagent / Condition Compatibility
DMSO (≤100%, compound plates) ✓ Excellent — inert polyester resists DMSO
Aqueous buffers / media ✓ Excellent
Short-chain alcohols ✓ Excellent
Dilute acids / alkalies ✓ Good
Formalin (brief contact) ✓ Good
High-temperature PCR (≤100°C) ✓ Compatible — acrylic adhesive rated for PCR
Autoclave ✗ Not compatible
Concentrated organic solvents ✓ Good — inert polyester broadly resistant

Laboratory Applications

EZ-Seal™ serves pharmaceutical HTS programs sealing 96-well and 384-well compound library plates for long-term DMSO compound storage; qPCR and RT-PCR programs sealing PCR plates before thermocycling; clinical and research ELISA programs sealing antibody-coated plates during overnight 4°C incubation; biobank and biorepository programs sealing sample plates for archiving; high-throughput cell-based assay programs requiring tightly sealed plates during incubation; and any laboratory workflow requiring reliable plate sealing without heat-seal equipment.

Frequently Asked Questions — Caplugs® Evergreen

Is EZ-Seal™ compatible with real-time PCR (qPCR) detection through the film?

Yes. The uses a clear optically transparent polyester film compatible with fluorescence detection through the seal during real-time PCR thermocycling. Compatible with standard qPCR instruments operating in top-read fluorescence mode including Bio-Rad CFX96/CFX384, Applied Biosystems QuantStudio series, Roche LightCycler 96/480, and Agilent AriaMx. Confirm optical performance with your specific instrument model and dye channel (FAM, SYBR, ROX) before committing to bulk volume.

Is the EZ-Seal™ film DMSO-compatible for compound library plate sealing?

Yes. Inert polyester (PET) is resistant to DMSO at all concentrations — the critical property for compound library plate sealing where DMSO carrier solvent is present at 100% in concentrated compound stocks. Standard polyolefin and polypropylene adhesive films can allow DMSO vapor permeation or adhesive dissolution under prolonged DMSO exposure. The inert polyester EZ-Seal™ film maintains seal integrity in DMSO compound plate storage for standard compound library archiving timescales at -20°C and ambient temperature.

How do I remove the EZ-Seal™ film without leaving adhesive residue?

Peel the film from one corner using a steady, low-angle pull parallel to the plate surface. The acrylic pressure-sensitive adhesive is formulated for clean peel-off from PS, PP, and acrylic plate surfaces without adhesive deposit. Avoid sharp upward pulls that can tear the film and leave small adhesive patches. If any adhesive residue remains after peeling, wipe with a brief 70% ethanol swab on the plate flange surface.
