Serial Dilution Bags Greatly Benefit Microbiological Food Testing

摘要

Inlabtec has published a short article that discusses the benefits gained from use of application specific sterile plastic bags in microbiological food testing. The article compares the now standard protocol of using sample preparation bags for stomaching with how the Inlabtec Serial Diluter makes it possible to now perform serial dilutions in dedicated serial dilution bags expanding the use of bags as a cost and resource saving alternative to test tubes or cups prefilled with diluent. In stomaching a sample together with diluent is put into an inexpensive, sterile plastic bag which is vigorously pounded by paddles when placed inside the paddle blender. Using disposable sample preparation bags eliminates the considerable labour required to clean and sterilise reusable homogeniser cups, running costs are thus drastically reduced.
