Asked Questions

What does the use by date mean on Redipor® prepared media?

For Redipor media the Use By date is the last day on which the medium should be inoculated or exposed. Any incubation period that is normal for that product may begin on that day. For example a 14 day sterility test in TSB or a 5 day incubation for a TSA settle plate.

Are there any benefits to dip slides?

Dip slides can be less sensitive than contact plates or swabs and they often have less stringent QC release criteria. However there are circumstances where they have real advantages.

They are convenient and easy to use by the relatively less skilled.
They are ideal for testing water tanks and hygiene monitoring in food preparation and similarly clean but not aseptic environments. Most importantly they are ideal for field use because they are self contained and the slide can be incubated and assessed without opening the device.

We need a specific or bespoke media type. Can Cherwell 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.

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.

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.
