AQUA AQS-200
Electronic Single Channel Pipettor
Mid-Volume Plate Workhorse · 0.20% CV at Full Volume · 0.5 uL Resolution
Cell culture and large-volume immunoassay work demand volumes the AQS-100 can't reach reliably. The AQS-200 extends to 200 uL while holding 0.20% CV at full volume — the precision tier of a 100 uL pipette with the working range of a 1000 uL one.
Why The AQS-200?
The 100–200 uL band is where many cell culture, microbiology, and serial-dilution workflows operate — and where most labs are forced to choose between a 100 uL pipette running at the top of its range or a 1000 uL pipette running at the bottom of its range. Both compromise accuracy.
The AQS-200 is designed precisely for this band. 0.75% accuracy and 0.20% CV at the 200 uL nominal, with 0.5 uL increment resolution from 5 uL upward. One pipette covers what previously required two, and delivers higher precision than either compromise option.
200 uL NOMINAL ACCURACY
At full volume, the AQS-200 delivers 0.75% accuracy and 0.20% CV per the catalog spec, verified against DIN EN ISO 8655-2 at an ISO 17025 accredited lab.
LINEAR STEPPING MOTOR
Motor-driven piston eliminates the thumb-pressure variability that plagues manual pipettes. Aspiration profiles repeat to the same micro-step every cycle, holding accuracy across thousand-sample runs.
DETACHABLE 4.2V LI-ION
800 mAh rechargeable battery clips off the handle in seconds — 8 hours of operation per charge, ~2-hour recharge, with USB Type-A and Type-C charger options.
12 MODES + 6 PROGRAMS
Forward, reverse, mix, dilute, gel-load, titration, multi-stage aspirate, repetitive, sequential dispense and more. Six programs save to memory for instant recall on repeat assays.
"0.75% accuracy and 0.20% CV at 200 uL nominal." — The AQS-200 is purpose-built for the 5 – 200 uL window — the manufacturer's published spec at the nominal volume sets a precision tier that manual pipettes in this range cannot sustain across a full shift.
