AQUA AQVT-12
Electronic Adjustable Spacing Pipettor
Sub-Surge Scientificer Adjustable Spacing · 0.125 uL CV at 12.5 uL · 12-Channel · 360° Rotatable Head · 12 Programmable Modes
Sub-microliter pipetting across multiple plate formats traditionally meant single-channel transfers, row by row, well by well. The AQVT Series replaces that workflow with motorized 12-channel delivery and electronic spacing control from 4.5 mm – 9 mm — covering 384-well (4.5 mm) and 96-well (9 mm) plates in one programmable instrument.
Why The AQVT-12?
At 0.5–12.5 uL, manual multi-channel pipettes lose two ways at once: thumb-driven plungers cannot deliver consistent volumes across the row, and any plate-format change forces the operator back to single-channel work. NGS library prep, qPCR setup, and primer dilution workflows pay both penalties.
The AQVT Series eliminates both. Linear stepping motor control delivers 0.25 uL accuracy and 0.125 uL CV at the 12.5 uL nominal, while one-button electronic spacing across 4.5 mm – 9 mm lets one technician move samples between plate formats without putting the pipette down.
4.5–9 mm ELECTRONIC SPACING
One-button electronic spacing control covers 384 / 96-well plates — eliminating the row-by-row manual transfers between plate formats that destroy throughput and reproducibility.
12.5 uL NOMINAL ACCURACY
At full volume, the AQVT-12 delivers 2% accuracy and 1% CV per the catalog spec, verified against DIN EN ISO 8655-2 at an ISO 17025 accredited lab.
360° ROTATABLE HEAD
The head is fully tubeless and rotates a full 360°, keeping the display visible regardless of grip angle. Faster parameter checks and improved ergonomics on long protocols.
12 MODES + 6 PROGRAMS
Forward, reverse, mix, dilute, repetitive dispense, sequential, multi-stage aspirate, stepper. Six programs save to memory — recall complex protocols with one button.
"12 channels, 4.5–9 mm spacing, 2% accuracy at 12.5 uL." — The AQVT-12 replaces a manual workflow between 384 / 96-well plates with one motorized instrument and a single calibration certificate — the kind of consistency that previously required automated liquid handlers.

Ideal Applications
qPCR & NGS WORKFLOWS
qPCR plate setup, NGS library prep, and adapter ligation across plate formats where sub-microliter precision drives result quality.
PLATE FORMAT TRANSFER
Moving sub-microliter samples between 96-well, 384-well, and tube-strip formats without manual single-channel transfers.
PRIMER & PROBE WORK
Primer working dilutions, probe distribution, and master mix setup for high-throughput molecular diagnostics.
Other Models in the AQVT Series
Twelve channels covering an entire row of a 96-well plate or 384-well alternating row in one stroke — the highest-throughput format in the AQUA adjustable-spacing range. The AQVT-12 is one of 3 volume tier(s) offered in this series — same handle, same firmware, same spacing range.
