Product Introduction
In high-throughput biological and diagnostic laboratories, manual multichannel pipetting represents a severe operational bottleneck. Repetitive strain injuries (RSI), operator-dependent meniscus variations, well-to-well volume drift, and airborne cross-contamination compromise assay repeatability. When assembling high-density microplate assays, master mix evaporation and fatigue-induced pipetting errors often result in failed runs and costly reagent loss. The YA50-4 automated pipetting workstation was developed specifically to solve these throughput and quality challenges by delivering robust walk-away automation.
Engineered with a dedicated 96-channel air-displacement pipetting head and 4 motorized SBS deck positions, the YA50-4 automates liquid aspiration, dispensing, tip loading, and microplate transport with metrological precision. Covering a 2–50 μL operational volume range, the system delivers accuracy of ≤4% @5μL; ≤2% @25μL; ≤1.5% @50μL and precision CV of ≤2% @5μL; ≤1% @25μL; ≤0.8% @50μL. By automating complex protocols such as serial dilution, multi-reagent master mix distribution, and 96-to-384 plate reformatting, the workstation reduces assay preparation times from hours to minutes.
The compact 580mm × 350mm × 580mm footprint allows straightforward deployment inside standard Class II Type A2 biosafety cabinets or laminar flow clean benches. Complete control is provided by an external 11-inch Android touchscreen tablet operating via wireless Bluetooth or USB Type-C, enabling researchers to configure protocols, monitor run progress, and trigger automated cycles without opening cabinet sashes or disrupting sterile airflow curtains.

FAQ
Q1: How does the air-displacement mechanism ensure uniform delivery across all 96 channels?
The YA50-4 employs a precision-machined 96-channel multi-piston manifold driven by an ultra-fine micro-stepper motor and synchronized lead screw. Each channel utilizes individualized elastomeric seals and precision-bored piston cylinders that maintain identical pneumatic displacement. Factory metrology calibration verifies channel-to-channel variation across the entire 2~50μL range, ensuring CV values remain under ≤2% @5μL; ≤1% @25μL; ≤0.8% @50μL in strict accordance with GBT 41812-2022 and JJG 646-2006 standards.
Q2: Can the YA50-4 be safely installed and operated inside a standard biosafety cabinet?
Yes. The physical footprint of 580mm × 350mm × 580mm and weight of 26.2 kg are deliberately sized to fit through standard sash openings and occupy minimal working space within Class II Type A2 or B2 biosafety cabinets. Because the system utilizes an external 11-inch tablet communicating via wireless Bluetooth, operators can start, pause, and monitor protocols remotely from outside the sash glass, eliminating air curtain disruption and preserving sterile isolation.
Q3: Does the instrument require proprietary consumables, or can standard lab tips be used?
The YA50-4 features an engineered universal tip cone design that is fully compatible with standard robotic and conventional pipette tips adhering to standard tip specifications. Laboratories are not locked into expensive proprietary consumable agreements, which significantly reduces the cost per sample and allows organizations to leverage existing consumable inventory without sacrificing volumetric accuracy.
Q4: How does the workstation handle viscous reagents or liquids prone to foaming?
The control software provides multi-gear speed adjustments for both aspiration and dispense strokes. When handling viscous master mixes, enzymatic glycerol stocks, or detergents that tend to foam, operators can reduce the aspiration velocity and introduce a post-aspirate delay to equilibrate internal tip pressure. Furthermore, reverse pipetting mode can be toggled on the touchscreen to eliminate capillary retention and droplet clinging at the tip orifice.
Q5: How does the automated 96-to-384 plate reformatting function operate on this 4-deck deck?
The motorized X-Y tray accurately indexes the destination 384-well microplate across four quadrant positions (A1, A2, B1, and B2 offsets). In a sequence of four automated aspiration and dispense cycles from the 96-channel head, an entire 384-well plate is completely populated in under three minutes, delivering impeccable positional alignment and avoiding the manual tracking errors inherent in multi-quadrant hand pipetting.
