The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally invented the compound in 1938. [4] Polytetrafluoroethylene is a fluorocarbon solid , as it is a high- molecular-weight polymer consisting wholly of carbon and fluorine .
Nalgene is a brand of plastic products developed originally for laboratory use, including items such as jars, bottles, test tubes, and Petri dishes, that were shatterproof and lighter than glass. The properties of plastic products make them suitable for work with many substances in various temperature ranges.
Today's Saran Wrap is no longer composed of PVDC in the United States, due to cost, processing difficulties, and health and environmental concerns with halogenated materials, [1] and is now made from polyethylene. [12] [13] [14] However, polyethylene has a higher oxygen permeability, which in turn affects food spoilage prevention.
A reagent bottle is a type of laboratory glassware. The term " reagent " refers to a substance that is part of a chemical reaction (or an ingredient of which), and "media" is the plural form of " medium " which refers to the liquid or gas which a reaction happens within, or is a processing chemical tool such as (for example) a flux .

Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon FEP. Other brandnames are Neoflon FEP from Daikin or Dyneon FEP from Dyneon/3M. FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP and PFA both share PTFE's useful ...
A wash bottle is a squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks. Wash bottles are sealed with a screw-top lid. When hand pressure is applied to the bottle, the liquid inside becomes pressurized and is forced out of the nozzle into a narrow stream of liquid.
In laboratory and other scientific settings, they are usually referred to simply as flasks. Flasks come in a number of shapes and a wide range of sizes, but a common distinguishing aspect in their shapes is a wider vessel "body" and one (or sometimes more) narrower tubular sections at the top called necks which have an opening at the top.
