Dip slides for microbiological monitoring of surfaces and in liquids. Each slide has media on both sides, with a choice of the same medium, or two different media on the two sides of the slide. This allows sampling of two surfaces with every slide. Testing with dip slides is a safe, reliable, economical and fast indicator of the presence of microorganisms. Dip slides, with a push cap, have a larger contact area.

Validation of aseptic processing should include a simulation test using a nutrient medium, known as the media fill or media simulation test. The selection of the nutrient medium should be made based on the quantity of the product produced, and the selectivity, clarity, concentration and suitability for sterilisation. The process simulation test should imitate, as closely as possible, the routine aseptic manufacturing process, and include all the critical subsequent manufacturing steps. Normally process simulation tests should be repeated twice a year per shift and process. The number of containers used for media fills should be sufficient to enable a valid evaluation. For small batches, the number of containers for media fills should at least equal the size of the product batch.
