Fluid K - Ready-to-use Rinse Fluid

Fluid K is designed as a washing solution for sterility testing of petrolatum solutions or oil-soluble pharmaceutical products using the membrane filtration method. Post filtration, the membranes are rinsed with Fluid K, whose composition also supports the growth of microorganisms upon incubation.

Fluid K is suitable for sterility testing of petrolatum products or oil-soluble pharmaceutical products. The washing solution serves as a medium for the growth of microorganisms in test samples. The fluid is also excellent for rinsing pathways of medical devices and products that are difficult to filter or dissolve.

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 slightly yellowish.
