CAS Number :
9002-18-0
Product Identifier
| Product Name | Agar Agar, Type I |
|---|---|
| SKU | GRM666 |
Directions:
Agar Agar Type I is produced for use in bacteriological routine laboratory work, plant tissue culture media, pharmaceutical preparations, where clarity, compatibility are not of prime importance. When suspended in cold water, it swells but does not dissolve. However, it readily dissolves in boiling water and solubility is facilitated by soaking the powder in cold water.
Safety Information
Read the label before opening the container. Wear protective gloves/protective clothing/eye protection/face protection. Follow good microbiological lab practices while handling specimens and culture. Safety guidelines may be referred in individual safety data sheets.
