Petri dishes on demand

Pre-filled or empty Petri dishes are stored in bulk at one end of the system

West Yorkshire, UK-based Don Whitley Scientific offers the Petri-Flow laboratory system to automate the transportation of Petri dishes from receipt of sample to analysis.

Manufactured by UK firm Zisys to suit individual requirements and workflows, Petri-Flow improves productivity of microbiological testing in food, clinical and water laboratories, the company says.

A key feature of the Petri-Flow is the LIMS connection, which ensures that sample information is printed directly onto each dish, both as a machine-readable barcode and a record of key test details that a technician can easily read. This helps to eliminate manual labelling errors and ensure failsafe identification of the samples from collection to image analysis, according to Don Whitley Scientific.

Petri-Flow allows pre-filled or empty Petri dishes to be stored in bulk at one end of the system. It stacks dishes in accordance with pre-programmed protocols for each sample type before transporting them to a laboratory workbench for inoculation. Samples can then be conveyed to the media pouring station, if required, prior to storage in an incubator.

The company says this flexible modular system can be adapted according to sample throughput and expanded according to the budget using a variety of accessories. It is easy to keep clean and features a built-in conveyor belt cleaning attachment.
