The oxygen may be diminished to 75% of it's normal percentage in air before appreciable symptoms develop. The effect of simple asphyxiant gases is proportional to the extent to which they diminish the amount (partial pressure) of oxygen in the air that is breathed. At low oxygen concentrations, unconsciousness and death may occur in seconds without warning. Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death. Inhalation: This gas is inert and is classified as a simple asphyxiant. Inhalation risk: On loss of containment this liquid evaporates very quickly causing supersaturation of the air with serious risk of suffocation when in confined areas.Įffects of exposure: Inhalation: Simple asphyxiant. Routes of exposure: The substance can be absorbed into the body by inhalation. Neon is a rare gas that is found in the Earth's atmosphere at 1 part in 65,000. Neon is usually found in the form of a gas with molecules consisting of a single Neon atom. Neon in the environment Although neon is the forth most abundant element in the universe, only 0.0018% in volume of the earth's atmosphere is neon. Liquefied neon is commercially used as an economical cryogenic refrigerant. Neon and helium are used to make a type of gas laser. Other uses of neon include high-voltage indicators, lightning arrestors, wave meter tubes and television tubes. Neon is also used generically for these types of lights when in reality many other gases are used to produce different colors of light. The reddish-orange color emitted in neon lights is widely used to make advertising signs. In addition, neon forms an unstable hydrate. The ions, Ne +, (Ne Ar) +, (Ne H) +, and ( HeNe +) are have also been observed from optical and mass spectrometric research. It is not known for certain if this or any neon compound exists naturally but some evidence suggests that this may be true. It is a less expensive refrigerant than helium in most applications.Įven though neon is for most practical purposes an inert element, it can form an exotic compound with fluorine in the laboratory. The the refrigerating capacity of helium is over 40 times the one of liquid helium and three times that of liquid hydrogen (on a per unit volume basis). Neon is the second-lightest noble gas, its colour is reddish-orange in a vacuum discharge tube and in neon lamps. Neon Neon was discovered by William Ramsay and Morris Travers in 1898.

It includes safety features such as 110-VAC-to-low-voltage power adapters, tamper-resistant screws, impact-resistant acrylic enclosure, easily locatable bright red laser shutter, bright and very durable nickel-plated laser aperture, industry-standard electrical connections and tripod mount. From the initial concept, everything about the attractive, safe design was intended to interest students in technology. They are not an engineering product or design being sold for educational purposes. It is the lowest powered and most economical laser we offer (.5 mW of laser power is adequate for most basic optical experiments as long as there is not bright light in the room.)ĬT Series lasers were specifically designed for use in education. It is useful in most educational curricula as a beginning tool for exploring/experimenting in laser and optical technology. The IF HN05 is a basic helium-neon CDRH Class II-rated laser. With a complete set of features and long warranty, it is a product that is hard to surpass. Designed for education, and featuring a bright blue transparent enclosure, their attractive looks invite students to participate and explore in optical and laser technology while seeing the laser's internal "working" components. Industrial Fiber Optics' CT Series of lasers are the most popular line of lasers used in middle and high schools in the United States. Economically priced, full-size helium neon lab laser
