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.

Compatibility: Ammonium sulfate is generally compatible with other fertilizers, and it can be used in combination with them to provide a balanced nutrient profile.
Safety Considerations: When handling ammonium sulfate, it's important to follow safety guidelines and use appropriate protective equipment to prevent skin or eye contact and inhalation.
Storage: Ammonium sulfate should be stored in a cool, dry place to prevent moisture absorption.
Fluorescence Method Dissolved Oxygen Analyzer is based on the principle of fluorescence quenching, blue light irradiates to the fluorescent material to make the fluorescent material excitate red light, because the oxygen molecules can take away the energy (quenching reaction), the time and intensity of red light and the concentration of oxygen molecules are inversely proportional. By measuring, the phase difference is excitated between the red light and the reference light, then to calculate the concentration of oxygen molecules by corresponding to the internal calibration value. By adopting innovative new fluorescent technology, no membrane and electrolyte is needed, almost no maintenance, excellent performance, easy to operate, no oxygen consumed, can be applied to any occasion, including those low water cycle.
