Contact Plate Agar
Contact Plate Agar is used to enumerate microorganisms by the direct application of the agar to the surfaces to test.
The use of this simplified technique is a good verification of the state of cleanliness of equipment after cleaning and disinfection. It can also be used to determine the bacterial load on the hands and fingers of personnel.
The agar can also be used for air control.
Available as dehydrated medium : 500 g bottle
In compliance with regulatory requirements, a USDA permit (VS 16-3) is mandatory for shipments from Canada to the USA due to the inclusion of peptone, an animal byproduct.
The combination of Tryptone and soy peptone leads to an optimal growth due to the synergy between the proteins supplied by casein and the carbohydrates supplied by soybeans.
Sodium chloride maintains the osmotic balance.
The medium is derived from Tryptone-Soy Agar and contains 4 neutralizers that inactivate most disinfectants that may be present in trace quantities after cleaning. This combination facilitates the development of residual viable microorganisms.
The lecithin-polysorbate-histidine-thiosulfate combination neutralizes most disinfectants.
The polysorbate neutralizes hexachlorophene and phenols.
The lecithin neutralizes chlorhexidin and phenol.
Lecithin and polysorbate combination inhibits quaternary ammonium salts.
Sodium thiosulfate neutralizes halogen derivatives.
