Breathable adhesive sealing film covers culture plates while allowing gas exchange through the membrane. It is a different choice from a vapor-tight storage seal: select the membrane around oxygen demand, incubation time, shaking and acceptable liquid loss.

| Component | Function |
|---|---|
| Breathable membrane | The illustrated grade has a fine fibrous texture rather than large visible perforations. |
| Adhesive sealing zone | Holds the membrane against the plate rim during the intended workflow. |
| Release liner | Protects the active surface before placement. |
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) | Selection note |
|---|---|---|---|
| Alternative permeability grade | 200 ± 10 µm | 142 × 83 | Request membrane composition and gas/vapor transmission data. |
| Fibrous rayon reference grade | 260 ± 10 µm | 142 × 83; 153 × 82 | Match tab arrangement and usable sealing area to the plate. |
| Item | Selection information |
|---|---|
| Sealing method | Manual adhesive application |
| Reference packaging | 100 sheets/box |
| Typical selection setting | Microplate culture and incubation requiring gas exchange |
| Critical trade-off | Gas exchange versus evaporation under actual incubation conditions |
For microbial culture screening and other plate-based incubation methods that require gas exchange. Plate fill volume, orbital shaking and incubation humidity should be considered together with the membrane.
Fibrous breathable sheet and its application to a deep-well demonstration plate. 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. Permeability depends on composition and structure. Compare measured gas and vapor transmission data for the exact grade.
Confirm the required gas exchange, incubator humidity, sterility and cell-culture protocol with a trial; no universal culture compatibility is implied.
Gas-permeable covers can still allow water loss. The acceptable balance depends on incubation conditions and assay sensitivity.
