Thermo Scientific™ Violet Red Bile Glucose Agar Contact Plate

Description

Selectively enumerate Enterobacteriaceae in food, animal feed, and environmental samples with Thermo Scientific™ Oxoid™ Violet Red Bile Glucose (VRBG) Agar Contact Plate while adhering to ISO 21528 and ISO 11133. Due to the careful addition of selective inhibitory components, neutral red, crystal violet, and bile salts, the medium provides selectivity against non-target Gram-positive bacteria. The medium is tested in accordance with International Pharmacopoeia^1,2,3,4.

Perform effortless surface sampling with easy-to-handle Violet Red Bile Glucose Agar Contact Plate.

• Easy-to-read results due to inclusion of neutral red indicator and crystal violet in the medium. Enterobacteriaceae form purple-pink colored colonies.
• Easy-to-handle contact plate format for effortless surface sampling.
• Adheres to ISO 21528 and ISO 11133:2014 standards.
• Conforms to formulations detailed in International Pharmacopoeia
• Ready-to-use convenience of prepared media.

Prevent agar from falling out of the dish with Thermo Scientific Contact Plates, which feature a dome-shaped bottom. GripFit™ technology makes plates easy-to-handle and ensures the lid remains in place during handling, while being easily removed during environmental monitoring. An inner layer on the base of the plate is sub-divided into grids to allow easy calculation of colony forming units (CFU) from surface tests, enabling labs to report whether contaminant levels fall within pre-defined acceptable limits. Easy stacking provides more stability during handling and transport, and ventilation is reduced to prevent plates from drying out.

Our contact plates are manufactured using a specialized, automated procedure to ensure a smooth, evenly distributed layer of agar on each plate. Surface sampling is achieved by gently rolling the domed surface of the agar onto the area to be tested. If any microorganisms that can cause disease or infection are present, they will grow to form easily visible colonies on the surface of the agar. This offers a reliable and effective way of determining the microbial cleanliness of surface areas and help control invisible dangers associated with microbial contamination. Clearly visible growth is available within three days for bacteria and within five days for fungi.
