AQUA AQVE-300A
Electronic Adjustable Spacing Pipettor
Plate-Filling with Adjustable Spacing · 1.8 uL CV at 300 uL · 8-Channel · 360° Rotatable Head · 12 Programmable Modes
Wash buffers, blocking solutions, and large-volume ELISA fills demand both reach and channel-to-channel uniformity. The AQVE Series (Variant A) covers 10–300 uL across 8 channels with electronic spacing from 4.5 mm – 14 mm, holding 1.8 uL CV at the 300 uL nominal.
Why The AQVE-300A?
Wash steps, blocking buffers, and large-volume substrate addition run at 100–300 uL per well across every assay plate — volumes where serological pipettes lose accuracy and manual multi-channels lose channel uniformity. In high-throughput diagnostic labs, that variability shows up as elevated background and reduced dynamic range.
The AQVE Series (Variant A) motorizes both the volume and the format flexibility. Linear stepping piston control across all 8 channels delivers 4.8 uL accuracy and 1.8 uL CV at the 300 uL nominal, with one-button spacing across 384-well (4.5 mm), 96-well (9 mm), and 48-well (13 mm) plates.
4.5–14 mm ELECTRONIC SPACING
One-button electronic spacing control covers 384 / 96 / 48-well plates — eliminating the row-by-row manual transfers between plate formats that destroy throughput and reproducibility.
300 uL NOMINAL ACCURACY
At full volume, the AQVE-300A delivers 1.6% accuracy and 0.6% 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.
"8 channels, 4.5–14 mm spacing, 1.6% accuracy at 300 uL." — The AQVE-300A replaces a manual workflow between 384 / 96 / 48-well plates with one motorized instrument and a single calibration certificate — the kind of consistency that previously required automated liquid handlers.
