Clear adhesive PCR sealing film covers the reaction wells while allowing visual inspection of the plate. Select the sheet dimensions, handling-tab design and adhesive grade that match your PCR plate and preparation workflow.
Clear adhesive PCR sealing film covers the reaction wells while allowing visual inspection of the plate. Select the sheet dimensions, handling-tab design and adhesive grade that match your PCR plate and preparation workflow.
| Component | Function |
|---|---|
| Polyolefin film | A thin, continuous flexible membrane across the plate surface. |
| Adhesive contact area | Creates the bond at the plate rim; wrinkles or wet rims can interrupt contact. |
| Release liner and tabs | Protect the adhesive before use and provide a grip area outside the wells. |
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.
| Configuration | Nominal thickness | Sheet size (mm) | Handling choice |
|---|---|---|---|
| High-clarity, single-tab | 100 ± 10 µm | 133 × 84 | Single handling tab |
| High-clarity, liner variant | 100 ± 10 µm | 136 × 80 | Confirm liner and usable sealing area |
| Standard / high-clarity variants | 100 ± 10 µm | 137 × 80 | Specify the intended grade, not dimensions alone |
| Item | Selection information |
|---|---|
| Sealing method | Manual adhesive sealing |
| Film material | Polyolefin for the reference configurations |
| Reference pack | 100 sheets/box |
| Selection factors | PCR plate resin, rim shape, thermal program and required seal removal |
For PCR plate preparation and temporary plate closure in laboratory workflows when the chosen adhesive grade is qualified for the intended conditions. Use a dedicated optical grade when fluorescence must be read through the seal.
Clear film shown before and after removal from a demonstration plate. Round impressions are not pre-cut holes. Plate 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.
Not necessarily. Compare the adhesive construction, instrument optical requirements and qualification data before selecting a replacement.
Do not assume the original seal remains intact after peeling. Reuse needs assessment for residue, adhesion and sample exposure; use a new seal where the workflow requires it.
Provide the plate model or drawing, outside dimensions and well array, plus any tab clearance limits. Overall film size alone is not a compatibility test.
Send your plate and application details to Puretest for configuration review, sample availability and a quotation.
