2026
A novel sealing protocol to produce water-tight silicone-based seals for membranes of Polydimethylsiloxane (PDMS) chip devices. Intended for labs setting-up chip models and small-scale chip platform development. We demonstrate the protocol using plastic and native tissue membranes. This procedure only requires PDMS, toluene, mold, membrane, and a vacuum chamber.

Here we present a protocol for performing reactions in simple reaction vessels under low-to-moderate pressures of CO2. The reactions can be performed in a variety of vessels simply by administering the carbon dioxide in the form of dry ice, without the need for costly or elaborate equipment or set-ups.

The present protocol describes the maceration and cleaning of cadaveric bone with a vacuum-sealed, hot water bath immersion technique. This is a low-cost, safe, and effective method to produce anatomical specimens for surgical planning and medical education as an alternative to three-dimensional (3D) printed models.
FAQs
Stretching is central to how Parafilm sealing works. The wax-based film conforms around a container rim, including uneven surfaces, so the covering contacts the opening rather than simply lying across it. This creates a removable barrier that helps protect biological samples from contamination, reduces evaporation, and lowers the chance of accidental spills during handling.
The film does not create the fully airtight condition associated with a tightly closed vessel. Instead, it provides a barrier while permitting limited gas exchange. That distinction matters when researchers want to reduce contamination and evaporation without treating the container as completely isolated from its surroundings. The seal therefore supports handling but does not guarantee airtight isolation.
Its main distinction is the level of protection it provides. The film is removable and helps limit contamination, evaporation, and spills, but it is not characterized as airtight or sterile. Consequently, it can support routine biological handling and sample protection, yet it should not replace a closure specifically required to maintain airtight conditions or sterility.
Application centers on stretching the flexible film around the vessel’s rim so it conforms to the opening’s shape. Because the material is moldable, it can cover uneven surfaces rather than requiring a perfectly uniform edge. After use, the barrier can be removed. This straightforward workflow suits plates, tubes, flasks, and other laboratory containers.
Biologists use this approach with culture plates, tubes, flasks, and other containers during cell culture, microbiology, and sample storage. In these settings, the seal helps maintain sample integrity by limiting exposure-related contamination and evaporation and by reducing accidental spills. Its value is practical: it supports more consistent handling conditions without implying that every container has become sterile or airtight.
Do not rely on it alone when an experiment or storage condition requires an airtight or sterile closure. Parafilm can form a protective, removable barrier, but it is specifically distinguished from closures that ensure those conditions. Researchers should therefore treat it as a supportive sealing measure for biological work, not as a universal replacement for the container’s required closure.
