Quantifying resources needed per food analysis and an independent comparison of the manufacturing processes is helpful for the QC companies to holistically assess the efficiency of the various media preparation methods.
An independent food QC laboratory (BAV INSTITUT GmbH, A Tentamus Company, Germany) performed a comparative study of different production processes for buffered peptone water for microbiological examination of food in terms of time, energy, and water requirements.
Five different media manufacturing methods were compared, and process throughput times plus hands-on times of the employees were determined (Classic media production in the laboratory, use of a media preparator, ready-to-use media bags and the ReadyStream® system classic and combined with dilutor). Steps of media production, preparation of first dilution of the samples, and preparation and follow-up steps (e.g. cleaning of the instruments) were considered.
Key Takeaways
- Study: “traditional” vs “new” media preparation methods
- How to improve lab efficiencies
- New media preparation solution
Join this webinar to get a review of the current media preparation solutions, and to help you to improve your laboratory efficiency, and ultimately reduce your laboratory costs.
