2015 Automated Liquid Handling System Product Survey Results
Automated liquid handling (ALH) systems span the range from semi-automated multichannel pipettors to room-sized systems. The industry is trending toward versatile, modular ALH systems—seemingly for every budget. Likewise, instrumentation, software, and methods have followed the trend toward greater user accessibility.
Top 7 Questions You Should Ask When Buying an Automated Liquid Handler
- What kind(s) of dispensing technology is used? Peristaltic pump dispensing offers low prime volumes and backflushing; microprocessor- controlled syringes have fast output and high precision. Hybrid detection systems combine both technologies in one and can even add washing functions.
- Is plate handling automatable? Manual plate handling can slow productivity. Automating the process with a compatible microplate stacker increases throughput with walk-away operation.
- Can it accommodate magnetic or plastic bead-based assays? If using bead-based assays, it should be equipped with appropriate magnets or vacuum filtration for critical wash steps.
- What is the volume range, and how many different sample vessel types may be used?
- Ask about the software—is it integrated and user-friendly? Does it allow for pre-programmed and custom protocols?
- What is the flow rate spectrum? A wide flow rate spectrum allows use with sensitive cell-based assays to viscous liquids.
- What assay validation data is available for this specific liquid handler? This provides proof that the instrument performs as indicated.
