†5.77 of disodium hydrogen phosphate anhydrous are equivalent to 7.2g of disodium hydrogen phosphate dihydrate
Directions
Suspend 14.63g of Sodium Chloride Peptone Broth (Buffered) in 1 litre of water (purified as required). If required, add 1-10ml Tween® 20 or 80 per litre of medium. Mix well and distribute into final containers. Sterilize by autoclaving at 121°C for 15 minutes.
方向
将 14.63 克氯化钠蛋白胨肉汤（缓冲）悬浮在 1 升水中（根据需要进行纯化）。 如果需要，每升培养基添加 1-10 毫升 Tween® 20 或 80。 充分混合并分配到最终容器中。 通过在 121°C 高压灭菌 15 分钟进行灭菌。
Description
Sodium Chloride Peptone Broth (Buffered) is intended for the dilution of samples in the analysis of non-sterile products for microbial contaminants.
The combination of phosphate buffer, sodium chloride and peptone increases the viability of sensitive micro-organisms by providing an isotonic environment. This is of particular importance when trying to recover cells that may be stressed or sensitive to osmotic pressure.
This solution conforms to the harmonised Microbial Limit Testing chapters from the EP/USP/JP 1,2,3. Additional information about this and other products in our harmonised range can be obtained by downloading our Harmonised Culture Media Portfolio.
