stonylab Lab Sealing Film, 10cm Wide x 38m Long, Flexible and Highly Stretchable (Over 500%), Self-Adhesive Film for Secure Lab Container, Prevents Leakage and Evaporation

Description

Product Overview

The STONYLAB Lab Sealing Film is engineered to meet the rigorous demands of modern scientific research and industrial laboratory environments. Constructed from a high‑performance polymer blend, the film offers exceptional chemical resistance, maintaining its integrity when exposed to strong acids, bases, oxidizers, and a wide range of organic solvents. Its unique micro‑porous structure allows controlled airflow while still providing a robust barrier against dust, moisture, and volatile compounds. With dimensions of 10 cm width and 38 m length, each roll delivers ample material for multiple sealing tasks, and the film’s remarkable elasticity—exceeding 500% stretch—ensures a tight seal even on irregularly shaped containers. The self‑adhesive backing eliminates the need for additional tapes or clamps, simplifying the sealing process and reducing the risk of contamination.

Usage

Designed for versatility, this sealing film is suitable for a broad spectrum of laboratory applications. Researchers can employ it to seal vials, flasks, petri dishes, and micro‑centrifuge tubes during long‑term storage, preventing evaporation of volatile reagents and protecting samples from airborne contaminants. In analytical chemistry, the film’s chemical resistance makes it ideal for sealing reaction vessels that undergo harsh conditions, such as high‑temperature incubations or exposure to corrosive reagents. Quality control labs benefit from its ability to maintain sample integrity during transport, while educational institutions appreciate the ease of use for student experiments. The film also performs well in controlled‑environment chambers where precise humidity and gas exchange are required, thanks to its breathable yet protective nature.

FAQ

What temperature range can the film withstand?

The film is rated for continuous use from –80 °C up to 40 °C, making it suitable for both cryogenic storage and moderate heating applications.

Is the film compatible with all types of laboratory glassware?

Yes, the film adheres well to glass, plastic, and metal surfaces. For optimal adhesion, ensure the surface is clean and dry before application.

Can the film be used for long‑term storage of volatile chemicals?

Absolutely. Its airtight seal prevents evaporation and protects against external contaminants, preserving the purity of volatile reagents for weeks or months.

How many containers can be sealed with one roll?

That depends on the size of the containers and the amount of overlap used. A 38 m roll typically seals dozens of standard‑size vials or several larger bottles.

What should I do if the film does not stick properly?

Check that the sealing surface is free of oil, dust, or moisture. If the problem persists, contact STONYLAB technical support for troubleshooting assistance.
