Scharlau Violet Red Bile Lactose Agar (VRBL)

Scharlau Violet Red Bile Lactose Agar is intended for detecting and counting coliforms in milk and other dairy products. The manufacturer cites APHA and ICMSF, FIL-IDF 73B, ISO 4832 and ISO 5541-1 as the documented method context. The medium is also listed under the names VRB Agar, VRBA and VRBL, which help reconcile different procedure terminology. This is the lactose agar product, distinct from the dextrose formulation used for the enterobacteria endpoint. Reference 01-164-500 supplies the selected dehydrated agar. Prepared-media tubes and bottles shown on the family page are separate articles with their own packaging details. The selected article is supplied as 500 g of dehydrated medium in a vacuum-wrapped flask. Prepare it and perform incubation, reading and quality-control checks according to the applicable laboratory procedure and manufacturer instructions.
