Upgrades to a highly regarded microdispenser system allows the instrument fo replace up to five separate liquid handlers, saving operator time and instrumentation costs

The new BioTek (Winooski, VT, USA) MultiFlo FX Microplate Dispenser is now available with optional RAD (Random Access Dispense) technology to further extend its application range and flexibility. RAD technology offers single-channel dispensing to random individual microplate wells along with rapid reagent dispensing into large volume wells of 6- to 24-well microplates. MultiFlo FX can also be separately configured with an optional wash module for 6- to 384-well plates.
The Multiflo FX accommodates microplate types ranging from 6- to 1536-wells, and dispenses volumes of from one to three microliters accurately and precisely. BioTek's proprietary angled dispensing ensures compatibility with all dispense protocols including media exchanges with loosely adherent cell monolayers. For assays requiring minimum reagent usage, the MultiFlo's prime volume is less than one milliliter. A built-in priming trough is designed to allow both recovery of reagents or to send primed reagent directly to waste.

MultiFlo FX was especially designed for sensitive cell-based assays, ELISAs, and bead-based assays, with angled dispense tips and flexible flow rates to maintain cell integrity.

Due to its small footprint and base height of less than 20.3 cm, the MultiFlo FX readily fits on any laboratory bench or robotic system. It is easily integrated with the BioTek BioStack Microplate Stacker, allowing up to 75 plates to be dispensed automatically. Simplified programming via intuitive on-board software and a color touch screen display enable control of dispense patterns, and two integrated USB ports provide convenient file transfer and storage options.

“Microplate-based bulk dispensing can be complex, especially in an automated system,” said Jason Greene, BioTek product manager. “We specifically designed MultiFlo FX to streamline this process, providing more value through multitasking, and time savings.”
