Hence they are not appropriate for storing chemicals which react quickly or violently with atmospheric moisture such as the alkali metals; a glovebox or Schlenk-type apparatus may be more suitable for these purposes. Desiccators are sometimes used to remove traces of water from an almost-dry sample.
The collected water molecules are transported from leaf surfaces to an internal storage network via osmotic pressure with capacity sufficient for the plant's growing requirements. [ 1 ] The file snake ( Acrochordus granulatus ), from a family known as completely aquatic, has hygroscopic skin that serves as a water reservoir, retarding ...
A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant. Commonly encountered pre-packaged desiccants are solids that absorb water. Desiccants for specialized purposes may be in forms other than solid, and may work through other principles, such ...
In chemical processing industries like food processing, pharmacology, agriculture, and textiles, drying is an essential unit operation to remove moisture. [1] Vacuum drying is generally used for the drying of substances that are hygroscopic and heat-sensitive, and is based on the principle of creating a vacuum to decrease the chamber pressure ...
The correct storage of carcinogens is important in reducing exposure. Limit access to carcinogens, keep containers and amounts used as small as possible, double containers and chemical resistant trays. Store in a designated area with the appropriate hazard signs and ventilation if required.
A couple of weighing bottles. Weighing bottles are glass laboratory equipment used for precise weighing of solids. Most of the glass used in the bottles is thin and fragile glass, but sometimes they are also made of ceramics or plastics. Dishes tend to have many different shapes. The three most popular are:
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.
The heater is a plastic bag filled with magnesium and iron powders and table salt. When a meal pouch is placed in the bag and water is added, an exothermic reaction occurs which rapidly boils the water to heat the food. The U.S. Army began research into a chemical method to heating meals in 1973. The FRH was first issued in May 1990, and an FRH ...
