Parafilm HS234526B M Roll 125 ft x 4 in Heathrow Scientific Lab Film

Description

Product Overview

Parafilm M roll, model HS234526B, is engineered by Heathrow Scientific to meet the demanding sealing needs of modern laboratories. The roll measures 125 feet in length and 4 inches in width, providing a generous amount of film for both routine and large‑scale experiments. Its semi transparent, flexible composition allows it to conform tightly around irregular shapes such as test tubes, culture tubes, and flasks, creating a barrier that prevents leaks while still permitting gas exchange when required. The material is specifically formulated to resist most acids and alcohols, ensuring that the seal remains intact even in chemically aggressive environments.

In addition to its chemical resistance, the film’s waterproof properties protect samples from moisture ingress, which is critical for preserving the integrity of sensitive reagents. The roll is packaged in a compact box with dimensions of 5.24 x 5.12 x 4.33 inches, making storage simple and space‑efficient. With a weight of just 3.53 ounces, the product is lightweight yet durable, reflecting the high‑quality standards of Heathrow Scientific. Customer reviews consistently rate the product at 4.6 out of 5 stars, highlighting its reliability and ease of use across a wide range of laboratory applications.

Usage

Parafilm is ideal for sealing test tubes, beakers, flasks, and culture tubes during incubation, storage, or transport. Researchers often apply a strip of the film around the opening of a container, then gently stretch it to achieve a tight seal that prevents evaporation and contamination. Because the film is semi transparent, users can still monitor the contents without removing the seal, which saves time and reduces the risk of accidental exposure. The roll’s length allows users to cut pieces of any size, from small strips for microcentrifuge tubes to larger sections for bulk containers.

The film performs well in a variety of laboratory settings, including microbiology, chemistry, and molecular biology labs. It is compatible with most standard laboratory plastics and glassware, and its flexibility makes it suitable for sealing irregularly shaped vessels. When working with temperature‑sensitive assays, the film can be applied at room temperature and will maintain its seal for extended periods, provided the temperature does not exceed the material’s tolerance. For applications requiring gas permeability, such as cell culture incubations, the film’s design permits controlled gas exchange while still protecting against liquid loss.

FAQ

Can Parafilm be used with hot liquids?

Parafilm can safely seal containers with liquids at room temperature and moderate warmth, but it is not designed for direct contact with boiling liquids. For high‑temperature applications, consider a heat‑resistant sealing film.

How many times can the film be reused?

The film can be peeled and reapplied several times on smooth surfaces, but repeated stretching may reduce its sealing effectiveness. For best results, replace the film after several uses on the same container.

Is the film compatible with organic solvents?

Parafilm resists most common acids and alcohols, but strong organic solvents such as acetone or chloroform can degrade the material. Use alternative sealing methods when working with aggressive solvents.

What storage conditions are recommended for Parafilm?

Store the roll in a cool, dry place away from direct sunlight. Keeping the film at temperatures between 15°C and 25°C helps maintain its flexibility and prevents brittleness over time.

Does the film affect optical measurements?

Because the film is semi transparent, it minimally interferes with visual inspection, but it may slightly affect spectrophotometric readings if placed directly in the optical path. Remove the film from the measurement area for precise optical analyses.
