To complement our range of Redipor® prepared culture media products, we have developed accessories to help transport and position settle and contact plates in optimum locations.
Table top and floor stand options available in the settle plate stands, and a carrier for up to 20 Petri dishes or contact plates.
We also provide surface sampling instrumentation and can create tailored solutions to meet specific criteria. Many of our products have been developed to solve specific issues for large pharmaceutical manufacturers.
Electro-polished stainless steel stands
Developed to find a bespoke solution for a pharmaceutical manufacturer, our standard stand holds single or double settle plates 115mm above the surface. Alternative heights can be made to order.
Floor standing version of the settle plate stand
Stainless steel. Perfect for positioning settle plates in a non-intrusive but optimal location for environmental monitoring. Single and twin plate options available.
Can also be used to carry Petri dishes
Stainless steel carrier for transporting up to 20 contact plates or Petri dishes. Easy to clean and autoclave, and perfect for use with SAS air samplers.
Standardises microbiological surface control
Used in combination with contact plates, the Contact-Weight surface sampler ensures monitoring time and weight are fixed to obtain reproducible results.
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.
Typical requirements suggest 1,000 litres per air sample in high risk areas, such as: grade A filling lines, grade B clean rooms, operating theatres etc. As the criticality of the area reduces, the sample size can be reduced. The aim is to achieve a representative sample; so where higher counts would be expected, a smaller sample produces a more realistic number of cfu to count.
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.
Yes. We have almost thirty years' experience with helping pharmaceutical and associated industries deliver environmental monitoring processes critical to the manufacture of heavily regulated products.
We supply every component you need to create environmental monitoring processes. We also offer bespoke formulations, accessories and even packaging solutions for organisations with very particular needs.

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.
