Azithromycin is a broad-spectrum macrolide antibiotic commonly used in the treatment of various bacterial infections. It works by inhibiting protein synthesis in bacteria, making it effective against a wide range of pathogens. The product is available in different forms, including tablets, oral suspension, and injectable solutions. When using azithromycin, it's important to follow the prescribed dosage and complete the full course of treatment to avoid resistance.
In addition to pharmaceutical applications, azithromycin is also used in microbiological testing and culture media formulations. For example, it can be incorporated into certain agar media to inhibit the growth of unwanted microorganisms, allowing for the selective isolation of target organisms.
Other chemical compounds such as ginseng triol (53963-43-2), ethyl p-methoxycinnamate (24393-56-4), and propyl gallate (121-79-9) are widely used in analytical and research settings. These compounds are often employed in high-performance liquid chromatography (HPLC) for purity analysis, with specifications typically ranging from 97% to 99% or higher. They are also used in food safety testing, particularly in the detection of molds, yeasts, and other microbial contaminants.
For microbiological testing, several specialized media are available, including ShaPaul dextrose agar, which is used for surface sampling and the detection of common disinfectants like alcohol and phenolic compounds. Other media such as ITC broth additive medium (40437-72-7) are used for the enrichment of Yersinia enterocolitica, while CIN-1 agar is specifically designed for the isolation of this pathogen.
Additionally, tiger red agar (also known as Bengal red agar) is commonly used in food microbiology for the enumeration of molds and yeasts. VRBA (Violet Red Bile Agar) is another standard medium used for the detection of coliforms and E. coli in food and water samples. Biochemical media for Vibrio species, such as L-arginine-based media, are essential for the identification and differentiation of these bacteria.
Chlorophyll I (32791-84-7) is a natural pigment often used in HPLC analysis for its high purity (≥98%). It is also used in various biological and environmental studies.
Overall, these products play a crucial role in both clinical and industrial microbiology, supporting accurate microbial identification, contamination control, and quality assurance in various sectors. Prices may vary depending on the supplier, quantity, and specific application requirements. Always ensure that the products meet the necessary standards and are suitable for the intended use.
Compared with silver mirrors, copper-free mirrors are of a higher grade. After the Silver Mirror is plated with silver, a layer of copper will be plated to protect it to prevent the mirror from being damaged and easily scratched. The copper-free mirror is to replace the copper protective film with a passivation protective film, making the mirror more environmentally friendly and durable. The passivation protective film of the copper-free mirror makes the mirror more wear-resistant, and is superior to ordinary silver mirrors in adhesion and corrosion resistance.
In addition, we also sell Silver Mirror glass, silver mirror commonly known as waterproof mirror, mercury mirror, silver-plated mirror on glass surface, glass mirror, mirror glass, etc. Silver mirrors are widely used in furniture, handicrafts, decoration, bathroom mirrors, cosmetic mirrors, optical mirrors, and car rearview mirrors.
