Top 5 Things You May Not Know About Liquid Handling Systems
1. Demand for automated liquid-handling systems parallels the larger automation marketplace. Generally, the need for automation is based on speed or throughput, consistency of results, and the value of a lab worker’s time.
2. A current trend is that users continue to specify high-end liquid-handling systems that serve “workflow automation” needs rather than single-liquid dispensing operations.
3. Another recent development is that though full-blown robotic liquid handling systems are formidable, integrated systems with steep learning curves, that complexity is somewhat mitigated through improved interfaces.
4. The liquid handling market is now addressing users who lack the automation and coding experience demanded by larger automation systems.
5. The original, big-money driver for lab automation was high-throughput screening of drug candidates. While that market still exists, the “numbers game” has reduced from millions or hundreds of thousands of compounds to just hundreds or thousands.
Top 6 Questions You Should Ask When Buying a Liquid Handling System
1. What kind(s) of dispensing technology is (are) used?
2. Is the liquid handler automatable?
3. Can the liquid handler accommodate magnetic or plastic bead-based assays?
4. What is the volume range, and how many different sample vessel types may be used?
5. Ask about the software—is it integrated and user-friendly? Does it allow for pre-programmed and custom protocols?
6. What is the flow rate spectrum?
