Settle plates for air monitoring

The 90 mm settle plates contain 30 mL of agar to compensate for desiccation after active sampling of 1000 liters of air and are suitable for prolonged incubation to favor the detection of microorganisms.


Settle plates are either exposed to air for a certain time or used with a microbial air sampler to physically draw a pre-determined volume of air, for detecting microbial airborne contaminations. They can also be used for personnel applications (i.e. gloves).


Settle plates are available both as gamma-irradiated, triple-enveloped for clean rooms and non-irradiated, single-enveloped for less critical environments and are conform to international standards such as EU cGMP, FDA Aseptic Guidance and USP 34.


The 30 mL settle plates are available as Tryptic Soy agar (TSA), w/ or w/o Penase or Lactamator in various concentrations and Sabouraud Dextrose agar (SDA). They are supplemented with neutralizers such as lecithin (L), tween 80 (T), histidine (H) and sodium thiosulfate (Th) for inactivating a wide range of disinfectants. Paperless and secure identification of individual plates are granted by the 2D Data matrix barcode on each plate.

Steam Control GST E6 SS (BA coupons)

Steam Control GST E6 SS are used for regular control of steam sterilization cycles and validation of sterilizers. These biological indicators use a stainless steel BA finish support (coupon) previously inoculated with Geobacillus stearothermophilus (ATCC 7953) spores and enclosed in a steam permeable envelope. The coupons are produced under strictly controlled conditions in order to satisfy the requirements indicated in the current editions of USP and EP and in accordance with the ISO 11138 and EN 866 standards.
