Choose an optical plate seal around your qPCR instrument, reaction volume and plate surface. This family brings pressure-sensitive optical films together in one place, with initial-tack, low-tack and no-initial-tack options for different handling preferences.

| Component | Function |
|---|---|
| Clear continuous film | Covers the well array without intentionally open pores or pre-cut access slits. |
| Sealing layer | Needs even contact with every well rim; pressing only the outer perimeter is not sufficient. |
| Liner and handling tabs | Allow positioning while keeping fingers away from the active sealing surface. |
Use the configurations below to specify your inquiry. Dimensions and thicknesses are reference configurations, not a guarantee of stock or universal compatibility. The selected grade, usable sealing area, packaging and operating limits will be confirmed in the quotation and product specification.
| Option | Nominal thickness | Sheet size (mm) | Selection note |
|---|---|---|---|
| Initial-tack polyolefin | 100 ± 10 µm | 130 × 80; 137 × 80; 140 × 80 | Initial adhesion helps retain placement before final pressing. |
| No-initial-tack polyolefin | 100 ± 10 µm | 140 × 80 | Position first, then apply consistent sealing pressure. |
| Low-tack polyolefin | 110 ± 10 µm | 141 × 80 | Lower initial tack aids alignment; confirm final adhesion on your plate. |
| Item | Selection information |
|---|---|
| Format | Individual adhesive/pressure-sensitive optical sheets |
| Reference pack | 100 sheets/box, subject to selected grade |
| Plate fit | Confirm outer dimensions, usable sealing area and tab clearance |
| Qualification | Instrument optics, plate resin, cycling program and reaction volume |
For real-time PCR method development and routine fluorescence-based amplification after plate-and-instrument qualification. Compare seals using your actual assay rather than relying on visual clarity alone.
Pressure-sensitive optical film shown on a demonstration plate. Circular marks on lifted film are sealing impressions, not perforations. Plate and applicators are not included.
For a useful quotation, send your plate model or drawing, preferred film construction, sheet size or roll-feed requirements, application conditions, quantity and destination country. For heat-seal products, include the sealer model. If lot-specific quality documents or special packaging are required, list them in the inquiry so they can be checked for the selected grade.
Evaluate a representative sample under your actual workflow before changing a qualified laboratory consumable. A general family description does not replace grade-specific test data.
Choose around your plate-positioning workflow. Initial tack, low tack and no initial tack describe placement behavior, not a ranking of final assay performance.
No. Overall sheet size may include handling tabs. Confirm the usable sealing area, well-rim design and instrument clearance.
State the documents required in your inquiry. Optical measurements, sterility and nuclease declarations must relate to the exact supplied grade and lot.
Send your plate and application details to Puretest for configuration review, sample availability and a quotation.
