Description

Agar CAS NO 9002-18-0 is a natural polysaccharide hydrocolloid extracted from red algae, primarily composed of agarose and agaropectin. It is valued for its exceptional gelling, thickening, and stabilizing properties, forming strong, thermoreversible gels at low concentrations. This versatile product is essential for manufacturers in the food, pharmaceutical, and microbiological industries, where precise texture control and inert support media are critical requirements.

Application

• Food Industry: Used as a gelling agent, thickener, and stabilizer in confectionery (e.g., jellies, marshmallows), dairy products (e.g., yogurt, ice cream), bakery fillings, and canned meats.
• Microbiological Culture Media: Serves as the standard solidifying agent for nutrient agar plates and slants in laboratory research, clinical diagnostics, and quality control testing.
• Pharmaceuticals: Employed as a disintegrant in tablets, a suspending agent in liquid formulations, and a base for suppositories and controlled-release drug delivery systems.
• Molecular Biology: Used to prepare gels for electrophoresis (agarose gels) to separate DNA, RNA, and protein fragments.
• Plant Tissue Culture: Provides a solid, sterile support medium for the growth of plant cells and tissues in vitro.
• Cosmetics & Personal Care: Functions as a thickener and gelling agent in lotions, creams, toothpaste, and hair care products.
• Industrial Applications: Used as a clarifying agent in brewing, a sizing agent in textiles, and a component in impression materials for dentistry.

Quality Control

Our Agar is produced and tested to meet stringent quality standards suitable for food, pharmaceutical, and technical applications. We offer various grades, including Food Grade (FCC) and Bacteriological Grade, with specifications for gel strength, moisture, ash, and microbiological limits. A Certificate of Analysis (COA) detailing purity, physical properties, and compliance is provided with every shipment to ensure traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to atmospheric moisture.
