AHN pipet4u® Revolution 12-Channel Electronic Pipette (30–300 µL)

Overview

The AHN pipet4u® Revolution 12-Channel Electronic Pipette is an ISO 8655-2:2022–compliant precision liquid handling instrument engineered for high-throughput assay preparation, ELISA plate filling, PCR setup, and cell culture workflows in regulated laboratory environments. Unlike conventional manual multichannel pipettes, this device employs a brushless DC motor coupled with a closed-loop position-sensing system to deliver consistent piston displacement across all 12 channels—minimizing inter-channel variability and operator-induced fatigue. Its core architecture follows the gravimetric principle defined in ISO 8655-6:2022, where volume delivery is validated via calibrated analytical balance measurements under controlled environmental conditions (20–25 °C, 40–60% RH). Designed for seamless integration into GLP- and GMP-aligned workflows, the pipette supports audit-trail–enabled operation logging when paired with optional software modules.

Key Features

• 12-channel parallel dispensing with synchronized actuation and independent tip ejection per channel
• Adjustable volume range from 30 µL to 300 µL in 0.5 µL increments, optimized for reproducible transfer of viscous or volatile aqueous solutions
• Autoclavable lower assembly (up to 121 °C, 20 min, 1 bar saturated steam) — compatible with ISO 17665-1 sterilization cycles
• Rechargeable lithium-ion battery providing ≥10,000 pipetting cycles per full charge; USB-C charging interface with status LED indicator
• OLED display with intuitive icon-driven navigation, real-time volume confirmation, and error-code diagnostics (e.g., air-gap detection, tip fit failure)
• Universal tip compatibility with all major conical tip brands meeting ISO 8655-3:2022 dimensional tolerances
• Ergonomic design certified to ISO 10075-2:2021 for reduced musculoskeletal strain during extended use

Sample Compatibility & Compliance

The pipet4u® Revolution maintains metrological integrity across a broad spectrum of liquid classes, including aqueous buffers (PBS, Tris-HCl), glycerol-containing reagents (≤30% v/v), ethanol–water mixtures (up to 70%), and low-protein cell suspensions. It is not intended for highly corrosive (e.g., concentrated acids/bases), high-viscosity (>100 mPa·s at 20 °C), or particulate-laden samples without pre-filtration. All performance specifications comply with ISO 8655-2:2022 accuracy and precision requirements. Device firmware adheres to IEC 62304 Class B software safety standards. CE marking confirms conformity with EU Medical Device Regulation (MDR 2017/745) Annex I essential requirements for laboratory equipment.

Software & Data Management

While standalone operation requires no PC connection, the pipette supports optional data export via Bluetooth 5.0 to the AHN pipetManager™ desktop application (Windows/macOS). This software enables calibration certificate generation per ISO/IEC 17025 guidelines, user-defined protocol storage (up to 50 presets), and CSV-formatted usage logs—including timestamp, operator ID, volume setting, and cycle count. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements when configured with electronic signatures and role-based access control. Calibration intervals are tracked automatically and trigger configurable notifications prior to expiry.

Applications

• High-density microplate preparation for drug screening (96-/384-well formats)
• Parallel genomic DNA quantification and library normalization in NGS workflows
• Multi-step dilution series generation under ISO/IEC 17025 traceability
• QC/QA testing of raw materials in pharmaceutical manufacturing (ICH Q5A, Q5B)
• Cell seeding consistency validation in bioprocess development labs
• Standard curve generation for immunoassays requiring <2% CV across replicates

FAQ

Is the entire pipette autoclavable?
No—only the lower tip-cone assembly (including ejector sleeve and O-rings) is rated for autoclaving. The upper body housing, electronics, and battery must be cleaned using 70% ethanol wipes only.
Does it support reverse pipetting mode?
Yes—three programmable pipetting modes are available: forward, reverse, and repetitive dispensing—with adjustable aspirate/dispense speeds and pause intervals.
What calibration documentation is provided?
Each unit ships with a factory-issued ISO/IEC 17025–accredited calibration certificate (DAkkS or UKAS equivalent), traceable to PTB and NIST standards.
Can it be integrated into LIMS or ELN systems?
Via pipetManager™ API (RESTful JSON over HTTPS), enabling bidirectional data exchange with LabVantage, Benchling, and Veeva Vault RIM platforms.
How often does it require recalibration?
Annual recalibration is recommended under routine use; however, interval adjustment may be justified per risk assessment per ISO/IEC 17025 clause 7.8.2.
