C143245The ideal choice for sampling dry, sanitized surfaces in less critical areas
Feel free to contact!
RT/RTplus as well as Envirocheck® Contact Plates are designed for microbial monitoring of dry surfaces, e.g. floors, walls, textiles and working garments of personnel in controlled areas, encompass a versatile range of products for your environmental monitoring needs. Furthermore, they are used for active air sampling using our air sampler of the MAS series.
Formulations are available for determining total aerobic microbial count (Tryptic Soy Agar = Casein Soya Bean Digest Agar = TSA or Plate Count Agar = PCA), yeast and mold count (Sabouraud Dextrose Agar = SDA, DG 18 Agar or Malt Extract Agar = MEA) and total count for specified microorganisms.
Sanitized surfaces should be monitored using plates which contain neutralizers such as lecithin (L), tween 80 (T); histidine (H) and sodium thiosulfate (Th). These neutralizers are capable to inactivate a wide range of disinfectants. In addition to these features the RTplus Contact plates enable safe transportation and incubation under various aeration conditions.
Close lid in clockwise direction (CLOSED position) for:
Safe transportation from sampling area to the lab
A recommended, prolonged aerobic incubation period
Close lid in counter clockwise direction (VENT position) for:
Incubation under microaerophilic or anaerobic conditions
Short-term incubation under aerobic conditions
Secure and reliable:
Data matrix barcode on each plate: Safe and paperless identification of individual plates
Room temperature stability: Storable at site of use
