These fillers facilitate pouring or filling of the culture medium in multiple petri dishes of different diameters and depths; minimize the risk of contamination; increase the work efficiency; and reduce the overall procedural time. Key features of automated petri dish and agar plate fillers include capacity to fill several petri dishes in an hour, high filling speed, provision of integrated peristaltic pumps and a UV lamp for maintaining sterility, a variety of carousel sizes, and provision of touchscreen graphic interface with in-built internal control system programs. Some companies also offer additional features such as the shaker function to evenly distribute the medium into a petri dish, tube filler options, cooling options, wireless connectivity to computers, and provision of an optional secondary pump for additives and image inkjet printers for direct printing on petri dishes. These equipment are extensively used for high throughput pharmaceutical assays, cell-based assays, and microplate replicating, wherein preparation of the precision sample is required. Automated petri dish and agar plate fillers are widely used by pharmaceutical and biotechnology companies, contract research organizations (CROs), commercial microbiology laboratories, and to some extent, hospitals and clinical research institutes.
