21 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.

CO2 Analysis Solution for Food & Beverage Industry


PAC announces the launch of the new Antek R1140 Total Hydrocarbon Analyser, part of PAC’s TQACO2 complete analyser package. TQACO2 is a unique turn-key system with a single operating data system, for quality assurance of CO2 in primarily the food and beverage industries. The new R1140 replaces the R1040 analyser in the Process Analytics product portfolio.


In making the announcement, Lisa Houston, Director, Process Analytics & Elemental Analysis, stated: “Millions of dollars worth of beverages are unnecessarily discarded annually as a result of undetected contamination. The new R1140 Total


Hydrocarbon Analyser, as part of the TQACO2 package, is the solution to preventing undetected sulphur, total and aromatic hydrocarbon, oxygen, and moisture contamination in carbon dioxide. Fast, precise, robust, and reliable, this analyser package


can help prevent product losses, and preserve customer loyalty. ”Traditionally, sulphur in CO2 has been detected using a simple tape, stain tube, or ‘sniff’ test. But these tests are neither accurate nor reliable enough, and COS and other sulphur compounds are missed by tape and stain tube tests, resulting in product spoilage, waste, and loss of customer loyalty. PAC’s


TQACO2 can detect contaminants in CO2 that traditional tape and stain tube tests can’t, and pay back its investment quickly in product savings and quality assurance. Additionally, gas suppliers and bulk CO2 users can now generate their own load report to show compliance with specifications with the R1140 and TQACO2 system.
