Oxoid Dry-Bags speed up media preparation

Oxoid is now offering food microbiologists a fast 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 sterilisation 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 remove the need for glassware, 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, 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, said: '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.

The Dry-Bags are flat packed in boxes of five or 10 bags, which can be stored at room temperature, taking up much less space than fully-prepared media products and freeing up refrigerator space.
