Specimen application device for petri dish biological tests etc. - has three loops with two lateral loops being in different planes, opt. being of disposable plastic or of platinum

摘要

In bacteriological and microbiological investigations, the nutrient surface in a Petri dish is divided into three areas each separately inoculated. A device applying the specimen has three loops. In relation to the central loop, the two lateral loops are located in different planes or inclined in V-shaped fashion. Loops and handle may constitute a throwaway injected plastic assembly, or the loops may be Pt wires sterilisable by flame treatment, and integral with a Pt handle. ADVANTAGE - Combines simple inoculation procedure with inexpensive application implement.
