|
使用说明:
称取本品 23.5 克于 1L 蒸馏水或去离子水中 (可按比例增加或减少配制量),加热煮沸至完全溶解,分装,121℃ 高压灭菌 15 分钟,灭菌结束后请摇匀,以防琼脂沉积于器皿底部而凝固,备用。
注意事项:
1、pH7.0±0.2 (25℃)。
2、操作时避免与皮肤、眼睛直接接触,如不慎接触,请立即用大量清水冲洗。
3、本品仅用于实验室科研实验,不可用于临床诊断。
Plate Count Agar (PCA) is a general-purpose medium for microbial examination. It is suitable for the enumeration of total aerobic bacterial colonies in food, water and environmental samples. After dilution and plate spreading, the samples are incubated at 36 ℃. The microbial load of samples is calculated by counting colonies.

Instructions for Use:
Weigh 23.5 g of this product into 1 L of distilled or deionized water (the preparation volume can be scaled up or down proportionally). Heat and boil until completely dissolved, dispense into containers, and autoclave at 121°C for 15 minutes. After sterilization, mix well to prevent agar from depositing at the bottom of the vessel and solidification, then set aside for use.
Precautions:
1. pH 7.0±0.2 (at 25°C).
2. Avoid direct contact with skin and eyes during operation. In case of accidental contact, rinse immediately with plenty of clean water.
3. This product is only for laboratory research and experiments, and shall not be used for clinical diagnosis.
