Dry-Bags Make Light Work of Bulk Media Preparation

Oxoid Dry-Bags are a labour-saving, convenient and rapid way to prepare and dispense large volumes of culture media and diluents. Thermo Fisher Scientific announced a new customer application video that demonstrates to food microbiologists how Dry-Bags™ take the hassle out of media preparation.

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 remove the need for glassware, which makes them a safe and convenient option for food testing laboratories and eliminates washing of glassware and heat sterilisation. Once water is added and powder dissolved, the Dry-Bag is ready to use immediately. When empty, the bag is simply disposed of with normal laboratory waste.

“Our aim is to provide food microbiologists with products that enhance the efficiency of their laboratory,” said Cheryl Mooney, Food and Industrial Product Manager, Oxoid. “Using Oxoid Dry-Bags, ALcontrol Laboratories was able to free up their staff and resources for other important tasks, enabling them to increase capacity for product testing in their laboratory.”

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. 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 are flat-packed in compact boxes of five or ten bags, which can be stored conveniently at room temperature.
