Buffered NaCl-Peptone solution has low peptone, along with phosphate buffer and sodium chloride that maintains the viability of micro-organisms in the solution without supporting further growth. The polysorbate 80 also assists in the suspension of hydrophobic substances. It further serves to neutralize disinfectants such as quaternary ammonium compounds, iodine, and parabens.

Buffered NaCl-Peptone solution with 1% Tween^® 80 is suitable for the microbial examination of non-sterile pharmaceutical products. It is also used as a solution for sample preparation or as a dilution or washing solution.

Our ready-to-use media provide the highest level of quality and testing confidence. They have been formulated and tested to meet the pharmacopeia requirements. Sterility testing media and rinse solutions are manufactured in an ISO 9001, environmentally controlled production center. Each lot undergoes a stringent quality control (QC) procedure, including pH, sterility, and growth promotion tests. Our manufacturing approach ensures the highest level of clarity for our media and rinsing fluids, thus improving accuracy and reducing the risk of incorrect interpretation and false results.

The appearance of the medium is clear and colorless.
