Those in the market for an automated liquid handler have a number of considerations, as explained in this article. Types of dispensers for automated liquid handlers are peristaltic pumps, microprocessor-controlled syringes, and hybrid detection systems, with the latter combining both peristaltic pump technology and microprocessor control syringe technology in one system. The sample volume and flow rate required are dependent on the particular application, so it is wise to consider these as well. The throughput required is another important criterion in the selection of an automated liquid handling system; high throughput is appropriate in many instances, while low- and medium-throughput instruments may be applicable in others.
