AQUA AQVT-50
Electronic Adjustable Spacing Pipettor
Mid-Range Plate Workflow · 0.4 uL CV at 50 uL · Adjustable Spacing · 12-Channel · 360° Rotatable Head · 12 Programmable Modes
The 2–50 uL range covers the busiest plate-based workflows in modern labs — PCR setup, ELISA standards, antibody dilutions. The AQVT Series delivers it across 12 channels with electronic spacing from 4.5 mm – 9 mm, replacing what was previously a multi-pipette workflow with one instrument.
Why The AQVT-50?
PCR plate setup, restriction digest distribution, and ELISA standard curves all live in the 2–50 uL window — and all suffer when samples need to move between plate formats. Manual multi-channel pipettes hit the volume but lose throughput on every reformat.
The AQVT Series motorizes both the volume and the spacing. Linear stepping piston control delivers 1 uL accuracy and 0.4 uL CV at the 50 uL nominal across all 12 channels, with one-button spacing change covering 384-well (4.5 mm) and 96-well (9 mm) plates.
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.
50 uL NOMINAL ACCURACY
At full volume, the AQVT-50 delivers 2% accuracy and 0.8% 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 50 uL." — The AQVT-50 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
PCR & GENOMICS
PCR plate setup, restriction digests, and ligation reactions across multiple plate formats.
ELISA STANDARDS
Standard curve preparation, antibody titrations, and sample addition where plate-format flexibility matters.
FORMAT-SWITCHING WORKFLOWS
Sample reformatting between 96-well, 384-well, and intermediate plate types in molecular biology pipelines.
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-50 is one of 3 volume tier(s) offered in this series — same handle, same firmware, same spacing range.
