Repeater Pipettors

Repeater pipettors, also referred to as repeat dispenser pipettes, work by aspirating a single large volume and dispensing it as multiple sequential equal aliquots without requiring a refill between dispenses. Manual repeater pipettes are mechanically straightforward and require no power source, making them a reliable and cost-effective option for standard reagent dispensing tasks. Meanwhile, electronic variants add programmable control over aspiration and dispensing speeds, adjustable aliquot volumes, and improved consistency across the full syringe capacity. Repeater pipettes are ideal in tasks such as master mix distribution, aliquot preparation, and any application requiring a large number of identical transfers into individual vessels. When selecting a repeater pipette, key considerations include the range of compatible syringe tip volumes, the smallest and largest aliquot sizes the instrument can reliably deliver, and whether electronic functionality is warranted, depending on throughput and reproducibility demands. Syringe tip compatibility and per-tip consumable costs are also worth evaluating, as these vary across manufacturers and can represent a meaningful operational expense in high-volume laboratory settings.
