1.Name: Sodium nitrate
Chemical formula: NaNO3
Formula weght:84.99
2.Property:
(1) ordinary sodium nitrate: white little crystals or light yellow
(2) dry powder sodium nitrate: non-caking, showing loose status.
Density:2.257. It is liable to deliquesce, dissolved in water, soluble in liquid ammonia, slightly soluble in ethanol and glycerin, Melting Point:308. While being heated up to about 380 it will decompose and release oxygen and turn into sodium nitrite,as the heating goes on, it will decompose into oxygen, nitrogen and nitrogen oxide. It has strong oxidability and can cause combustion explosion if being mixed with organic substance, sulfur, sodium nitrate etc.
3. Usage:Â it has been wildly used in the glass industry, dye, dynamite, metallurgy, machinery, ceramic etc.

Apple is beauty to share, both to lose weight, but also make the skin smooth and soft. Apple is a low-calorie food, every 10 green apple 0 grams only produce 60 kcal calories; apple nutrient soluble, easy to be absorbed by the body, it is "living water," said, is conducive to dissolving sulfur elements, so that the skin lubrication soft The There are copper, iodine, manganese, zinc, potassium and other elements, the human body such as the lack of these elements, the skin will dry, easy to crack, itchy.
Vitamin C in the apple is the protective element of the cardiovascular, the health element of the heart disease.
Eat more apples than those who do not eat or eat less apples cold risk is lower So, there are scientists and physicians called the apple "all-round health fruit" or called "general practitioner". Air pollution is more serious, eat apples can improve the respiratory system and lung function, protect the lungs from the dust and dust in the air.

1.Product description
Name: Glutaraldehyde 50%
CAS NO. 111-30-8
Appearance: colorless or yellowish clear and bright liquid
2.characteristics and applications
Glutaraldehyde is colorless or yellowish clear and bright liquid with slight irritating smell, and can be dissolved in organic dissolvent such as water, ether and ethanol.
In water solution, Glutaraldehyde doesn't exist much in free state; instead, Glutaraldehyde makes appearance as hydrates with different forms.and most of them are hydrates with annular structure.
Glutaraldehyde is reactive in property, and liable to polymerize and oxidize, which will react with compounds containing active oxygen and nitrogen. The reaction of the product with protein is mainly carried out between the carbonyl group of the former and the amino group of the latter. Among the known aldehydes, the product is one of the best cross-linking agents for proteins.
Glutaraldehyde has a small influence on the activity of enzyme, and most of enzymes can be fixed under controlled condition, to cross-link without losing their activity. Contrbuting to its outstanding characteristics, the product has drawn special concern from people and been put at broad application.
Oxygen concentrators are typically used as stationary sources to provide long-term oxygen therapy (LTOT) to patients at home. Oxygen concentrators consist of a cabinet that houses the compressor and filters; tubing; a nasal cannula and/or face mask.
