Request Information

Ready-to-use Media for Passive Air Monitoring

Merck’s single-bagged non-irradiated 90 mm settle plates are the perfect choice for active and passive Microbial Air Sampling as part of your environmental monitoring routines in less critical areas. Each settle plate is labeled with a data matrix barcode, containing article number, lot number, serial number and expiry date. This paperless documentation enables secure data transfer, while saving time and effort. The Settle Plates can be stored at room temperature and have a long shelf life, adding to the convenience of these products.

LI (Long Incubation) Settle Plates

The LI Settle Plates from Merck are single-bagged and non irradiated and are thus an ideal choice for air monitoring in less critical areas. These plates contain either Tryptic Soy agar (TSA), a gerneral pupose medium, or Sabouraud Dextrose agar (SDA), which is ideally suited for the growth of yeast and molds. Both are prepared according to the recommendations of the European and US pharmacopeias. They are supplemented with neutralizers such as lecithin (L), tween 80 (T), histidine (H) and soidum thiosulfate (Th) to inactivate a wide range of disinfectants.

The LI Settle Plates come with a higher than standard filling volume of 30 ml to compensate for water loss during extended incubation periods. For safe and efficient documentation, they are barcoded, enabling each plate to be fully traceable back to its date of use and the location of sampling.
