Oxoid Dry-Bags make Media Preparation Fast and Easy

We now offer food microbiologists a fast and convenient way to prepare and dispense large volumes of culture media and diluents. Oxoid Dry-Bags™ are ready to use in a matter of minutes and contain sufficient material to make 20 litres (88 aliquots of 225ml) of medium or diluent.

Each Dry-Bag contains pre-weighed dehydrated culture medium or diluent and is irradiated for sterility. All that is required is the addition of water – either through filter sterilization or by adding pre-sterilised water under aseptic conditions. Dry-Bags are available with filters attached for convenience or without filters as a lower-cost option. For those Dry-Bags supplied without filters, autoclavable, reusable filters are also available. 

Oxoid Dry-Bags take the hassle out of media preparation. They remove the need for glassware, making them a safe and convenient option for food-testing laboratories and eliminating the need for washing of glassware and heat sterilisation. Furthermore, there is no need to wait for hot media to cool down.  Once water is added and powder dissolved, Oxoid Dry-Bags are ready to use immediately.  When empty, the bag is simply disposed of with normal laboratory waste.

Cheryl Mooney, food and industrial product manager, Oxoid, comments, “Our aim is to provide food microbiologists with products that enhance the efficiency of the laboratory. Oxoid Dry-Bags are both time-saving and space-saving, ensuring that staff and resources are free for other important tasks.”

Oxoid Dry-Bags are flat-packed in compact boxes of five or ten bags, which can be stored conveniently at room temperature, taking up much less space than fully prepared media products and freeing up valuable refrigerator space.  For further information about the range of media and diluents available as Dry-Bags, please speak to your local Oxoid representative.  For more information about how to use Dry-Bags please download our Dry-Bags datasheet.
