Agar Powder

Agar powder is composed of agarose and agar pectin, insoluble in cold water, soluble in boiling water, slowly soluble in hot water. In biology experiments, the working concentration is 6-25 g/L, and the dosage of agar powder routinely added to microbial culture medium and plant histoculture medium is 1.5-2.0%. When the agar powder does not solidify in the experiment, it is necessary to check the pH value of the medium, the concentration of agar powder, the temperature, the mixing situation, and so on.

If the pH of the medium is too low and acidic, the agar powder will be easily hydrolyzed and will not solidify. If the quality of agar powder is not enough, not fully shaken after dissolved in hot water, etc., it will lead to uneven solidification. Sterilization temperature is too high and heating time is too long, which will also lead to failure of solidification.

Transported at room temperature; stored in a cool and dry place, valid for 36 months.

Prepare microbiological medium in the amount of 15-20 g/L.
