Methods for the environmental monitoring of controlled spaces can be split into passive or active methods. Settle plates are the main passive method deployed for air monitoring, contact plates and swabs are used for surface monitoring whereas primary active methods are air samplers, which sample a known volume of air over or through a collection medium.
Many of the requirements for microbiological media remain the same whether the environment is a clean room, isolator, operating theatre, office, factory or waste processing site, This would apply to settle plates for air monitoring, contact plates for surface monitoring as well as plates for active air sampling.
At the point of use:
All Redipor agar plates are designed for storage at room temperature so that it is easier to deliver them to the point of use in good condition. We manufacture agar in Petri Dishes (55mm, 90mm and 140mm diameter) and in Contact Plates. All Redipor agar plates are supplied with a Quality Control Certificate and a batch record to give confidence in their performance.
For the pharmaceutical industry we manufacture Tryptone Soya Agar and Sabouraud Dextrose Agar with several different optional neutralisers for antibiotics and disinfectants. These are wrapped in a choice of multiple layers of sealed film and gamma irradiated in a sealed box to ensure that at the point of use, both the packaging and the agar surface are sterile.
For other environments we can supply selective or differential media to enable the detection of specific types of organism that might be of concern such as yeasts and moulds in ventilation systems or enterobacteriaceae and coliforms in beverage packaging areas. In this case each agar plate is intended to indicate the presence of those types amongst a background of mixed bacteria and sterile outer packaging is less beneficial.
We can also supply agar dip slides for convenient non-critical hygiene monitoring on surfaces and in fluids.
