55mm Contact Plates
Rodac plates are used for monitoring environmental hygiene (air and surfaces), to validate cleaning and disinfection operations, to apply Good Manufacturing Practices “GMP”, to increase HACCP system and to train staff to hygiene. Rodac plates allow recovering and growth of microorganisms, which are present in the environment, on suitable culture medium.
Rodac plates are used for monitoring environmental hygiene (air and surfaces), allowing recovering and growth of microorganisms, which are present in the environment, on suitable culture medium; beside they have the agar medium projecting over the opened plate, allowing a rapid contact of the medium with the surface under test. Disinfections and antiseptics, used for environmental sanitization, can inhibit microbial growth on the culture medium of the Rodac plates, so it is necessary that media contain substances inactivating disinfections and antiseptics: Lecithin, Histidine, Tween 80 and sodium thiosulphate neutralize disinfections and antiseptics commonly used such as ammonium quaternary compounds, phenolic derivates, aldehydes, mercury compounds and active chlorine. N.B.: For the products present in the previous tables and marked by the asterisk * (ref. 15323S, 15362, 15339S) neutralizing is constituted only by Lecithin and Tween 80. Tryptic Soy Agar Casein Soya Bean Digest Agar (Irradiated), Sabouraud CAF Agar (Irradiated), Plate Count Agar + Neutralizing (Irradiated), Sabouraud Dextrose Agar + Neutralizing (Irradiated), Sabouraud CAF Agar + Neutralizing (Irradiated) and Tryptic Soy Agar + Neutralizing Casein Soya Bean Digest Agar (Irradiated) plates are irradiated after packaging to assure the sterility of the outside envelopes (irradiation of the outside package is not performed for plates containing stainings).
