We can provide a great deal of information so that you can make an informed choice. Our [Growth Media Types page](https://www.cherwell-labs.co.uk/en-gb/growth-media-types) provides information on the different types of prepared media and how they are used in environmental monitoring, sterility testing and process validation as a starting point. For further information on other media and applications, please phone or email us with details. We need a specific or bespoke media type. Can AnalytiChem UK help? Our Redipor Prepared Media range is so extensive that not every product is included in the official price list. In addition to offering such a wide selection of products, we have developed a flexible manufacturing process enabling us to produce bespoke solutions. Contact us to discuss your requirements, whatever they are. Do I need to store my prepared media in the fridge? The majority of our prepared media can be stored in ambient conditions, not exceeding 25ºC. There are only a small number of very specialist products that require different storage conditions. We have never specified refrigeration as a storage condition for our general media as this causes excess condensation and can result in very wet agar, rendering it impossible to use. What is the maximum exposure time for settle plates? Settle plates are used to monitor the level of viable particles in the environment through a process of passive air sampling. A viable particle settles on agar plates at a rate dependent on its characteristics and the airflow in the environment. EU GMP Guide Annex 1 has recommended that 90mm settle plates can be exposed in cleanroom environments for up to 4 hours. However, agar plates may dry out during long exposures where the rate of air exchange is high. So, it might be necessary to use deep filled settle plates, or replace the settle plate after a shorter time to ensure satisfactory growth promotion after exposure. Why might I want gamma irradiated media? The sterility of the packaged medium is assured and all but the outer layer of packaging is also sterile. Thus the risk to the environment to be sampled is greatly reduced. There is an additional benefit that the additional packaging and process extends the room temperature shelf life. This can be sufficient reason for small or irregular users to prefer irradiated. What is the difference between general purpose and selective growth media? General purpose media have nutrients that support the growth of most non fastidious culturable microorganisms. Selective growth media contain components that will inhibit the growth of some types of microorganisms, while supporting the growth of others. General purpose media, such as Tryptone Soya Agar, are used to produce total counts. While selective media, such as XLD for Salmonella species, are used to test presence/absence of specific types of microorganism. What does triple wrap packaging mean? Not as obvious as it might sound. 3 layers of wrap between the agar plate and the outside world, of course, but Redipor can offer at least 3 different ways to achieve that with our standard product range. We then have even more bespoke solutions to meet individual needs. Let us know how and where you want to remove the layers and we can find the best solution. Can I recycle Redipor product packaging?
