Nalgene+Water+bottles

Nalgene, or thermo scientific nalgene, is a polyethylene plastic originally developed for laboratory storage as well as laboratory storage nalgene is now used in manufacturing water bottles, vials, and bags. Though the plastic is extremely effective it has come under fire with claims of the plastic secreting BPA. This chemical is led to gene altering, but the company suggests the chemicals are only secreted when it is used outside normal temperatures.

Many Nalgene water bottles and other hard plastic sport water bottles are made of polycarbonate (#7 on the bottom), which may leach Bisphenol A, an estrogen-like chemical. Canada is considering a ban of products containing Bisphenol A (BPA) and a new American study links it to breast cancer and early puberty, and is particularly concerned about the effect on babies. Others have raised concerns about the effect of feminizing hormones on men, such as breast enlargement or dropping semen counts. At the same time, sport water bottles are ubiquitous and we don't want people going back to buying bottled water. What should you do? Time to nix the Nalgene? We looked at our past posts and the latest reports, and suggest the following.

**Thermo Scientific Nalgene** is a brand of [|polyethylene] plastic developed and manufactured by [|Nalge Nunc International] originally developed for laboratory storage containers. It is now used in the manufacture of water containers, vials, bottles, bags and [|carboys] for packaging, shipping, and storage. The name Nalgene is a [|registered trademark]. That original Nalgene line included such items as [|jars], [|bottles] , [|test tubes] , [|graduated cylinders] , and [|Petri dishes] helpful to laboratory workers, chemists, and biologists because they were shatterproof and lighter than glass. The properties of the respective plastics make them suitable for work with many materials in various temperature ranges.

Nalgene Outdoor
In the 1970s, conservationists began [|discouraging] the former reckless approach of disposing of [|cans] and glass containers by [|burning] and [|burying] in wilderness and recreation areas, and some places began forbidding such materials by regulation. Thermo Scientific Nalgene products became popular replacements among backpackers for storing consumables; the light, wide-mouthed, [|HDPE] and [|Lexan] bottles were more secure than plastic bags, and found use for both liquids and solid foods.

Originally, wilderness travelers purchased Nalgene products through laboratory-equipment suppliers (or perhaps gained access to them in their workplaces). Company lore has it that the company president Marsh Hyman discovered that his son's [|Boy Scout] troop was using Nalgene lab containers when camping. Since then, the company has re-packaged and marketed items that most appeal to them for consumer sales through their line of Nalgene Outdoor Products. [|[1]] By the late 1990s, the "Nalgene" trademark was recognized by many hikers and sales of the 1-litre wide-mouth bottle of translucent polycarbonate (originally typically grey, but now commonly in bright colors, often with custom labels made for the bottle retailer) with a screw-on plastic top that stays attached when the bottle is open, began to increase. Now, most hikers and others recognize the distinctive appearance of Nalgene-branded bottles. Its laboratory pedigree is suggested by the markings, in hundreds of millilitres, of the volumes contained when filled to the corresponding levels. The materials resist stains or absorbing odors, and permit filling the bottle with boiling water. [|[2]] The wide-mouth bottle is more widely used and sold over the narrow-mouth bottles in sub-freezing conditions since it is easier to break through frozen ice in the wider mouth. Currently, Nalgene markets seven different kinds of bottles: Stainless, Grip n' Gulp, Multidrink, 32 oz. Wide Mouth, On-the-Fly, 32 oz. Glow, and Oasis. Products originated by other manufacturers, that are designed for compatibility with this item's overall dimensions or its 2.5 inch neck include: Another widely available Nalgene Outdoor product is a 650-ml (22-fl oz) "All-Terrain" or "bike" bottle. The bottle itself is [|LDPE], and its screw top has two moving parts: a drinking nozzle that seals until snapped open by pulling on it, and a hinged Lexan dome, that when closed both snaps the nozzle closed and protects the nozzle against contamination. Unlike traditional Nalgene containers, this item can be damaged and potentially ruined by filling it with very hot water. Recently, Nalgene has added [|hydration systems] to its cycling and wilderness product line. The line features 1- to 3-litre bladders with hose-and-bite-valve assemblies in small back-carried packs (mostly under 1000 cubic inches (16 L) of additional storage). Nalgene offers the option of two different bladder materials for a choice of superior taste and bacteria resistance versus improved durability. In addition, the bladder on these products can be quickly detached from the hose and pack by a self-sealing connector on the bladder. These features seemed aimed at dissatisfaction in traditional hydration systems with problems of awkward filling and/or spilling water into gear that shares the pack. Increased awareness of the importance of [|hydration] - and perhaps a [|fad] of [|wilderness chic] - has led to the appearance of some Nalgene containers in urban and suburban settings like gyms, offices, and campuses. Many colleges give or sell Nalgene water bottles to their students, and Nalgene bottles are also customized and sold as retail promotions.
 * Screw-on water-purifying filters
 * Stainless-steel collapsible-handle cups, for drinking and/or stove-top cooking, that store compactly with a Nalgene litre-bottle nested inside them
 * Insulated Nylon-fabric cases for Nalgene 1 litre bottles; features include stable attachment points and, in most cases, nesting for a cup
 * Snap-in plastic "splash guards" that narrow the neck opening to a size where drinking while in motion is less likely to cause spilling
 * Screw-in filters, which allow the user to add coffee grounds or tea, pour boiling water over the contents, seal the lid, and brew the beverage.
 * Screw on LED lights, creating a usable lantern with low power consumption.
