PARAFILM Meaning and
Definition
-
Parafilm is a brand name that refers to a thin and transparent, flexible tape widely used in laboratories for sealing containers and preventing the entry or escape of air, moisture, or other contaminants. It is composed of a blend of high molecular weight waxes and polyolefins, which provide it with its unique properties.
The tape is commonly used in scientific and research settings for various purposes, including wrapping around the neck of flasks, test tubes, and other laboratory vessels. It molds tightly to the surface, creating a seamless and airtight seal that helps to maintain the integrity of the samples or substances contained within.
Parafilm has excellent elasticity and conformability, allowing it to stretch and form a tight seal when stretched over the opening of a container, not requiring any additional adhesive. Its pliability also enables easy peeling and resealing, making it a convenient option for repeated use.
In addition to providing a physical barrier to external elements, parafilm is also gas permeable, allowing for the exchange of gases without compromising the seal. This permeability makes it ideal for culturing cells, incubating and fermenting biological samples, and maintaining controlled environments during chemical reactions.
Overall, parafilm is a versatile and reliable sealing material commonly found in laboratories, providing a cost-effective solution for maintaining the integrity and sterility of samples while allowing for necessary gas exchange.

Etymology of PARAFILM
The word "Parafilm" is a compound word derived from "para" and "film". Here's a breakdown of their etymology:
1. "Para": This derives from the Greek prefix "para" (παρά), which means "beside" or "beyond". In English, it is commonly used to indicate something that is similar or related to something else but not identical.
2. "Film": This word traces back to the Latin term "film" or "filma", which originally referred to a thin skin or membrane. It later extended in meaning to include thin, flexible sheets or layers of various materials.
When combined, "para" and "film" form "Parafilm", which suggests a thin, flexible material that is related to or resembles film.
