The BioTek Microflo Select Reagent Dispenser brings a self-contained, universal microplate dispenser that’s programmable and adjustable. This plate dispenser can be adjusted for height and volume, so it can accommodate all standard and deep well formats, even test tubes under 4 inches with the use of a special carrier (sold separately). The Microflo Select is outfitted with a 1uL cassette but can be changed out allowing you flexibility in volume. This microprocessor-controlled reagent dispenser has an onboard computer that saves your 10 most commonly used protocols in quick access and will hold up to 99 user-defined programs in memory, or simply dispense straight away for most common applications.
